How to Searching Across All Tables in SQL Server for Specific Data

Introduction

Searching for specific data in a database with hundreds of tables can be a challenge. This guide demonstrates how to dynamically search all tables in SQL Server for a specific value using a script. This approach is useful when you don’t know which table or column contains the data.

Why This is Useful

  • Large databases with many tables and columns.
  • Unfamiliarity with the database schema.
  • Debugging or data migration tasks.

The SQL Script

Below is a complete script you can use to search for any value across all tables and columns in your database. It works for text and GUIDs (uniqueidentifier), handles missing tables, and avoids syntax issues.

DECLARE @SearchValue NVARCHAR(255) = 'your_search_value'; -- Replace with your value
DECLARE @SQL NVARCHAR(MAX) = '';
DECLARE @TempSQL NVARCHAR(MAX) = '';

-- Dynamically build the SQL query for all text-based and uniqueidentifier columns
SELECT @TempSQL = (
    SELECT 
        CASE 
            WHEN OBJECT_ID(TABLE_SCHEMA + '.' + TABLE_NAME, 'U') IS NOT NULL THEN 
                'SELECT ''' + TABLE_SCHEMA + '.' + TABLE_NAME + ''' AS TableName, ''' + COLUMN_NAME + ''' AS ColumnName, ' +
                '[' + COLUMN_NAME + '] AS MatchFound ' +
                'FROM [' + TABLE_SCHEMA + '].[' + TABLE_NAME + '] ' +
                'WHERE [' + COLUMN_NAME + '] LIKE ''%' + @SearchValue + '%'' UNION ALL '
            ELSE ''
        END
    FROM INFORMATION_SCHEMA.COLUMNS
    WHERE DATA_TYPE IN ('char', 'varchar', 'text', 'nchar', 'nvarchar', 'ntext', 'uniqueidentifier')
    FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)');

-- Remove the trailing 'UNION ALL'
IF LEN(@TempSQL) > 10
    SET @SQL = LEFT(@TempSQL, LEN(@TempSQL) - 10);

-- Execute the dynamically generated SQL if valid
BEGIN TRY
    IF @SQL <> ''
        EXEC sp_executesql @SQL;
    ELSE
        PRINT 'No matching data found.';
END TRY
BEGIN CATCH
    PRINT 'An error occurred, but it was ignored: ' + ERROR_MESSAGE();
END CATCH;

How It Works

  1. Dynamic Query Generation:
    • The script dynamically generates SQL queries for all tables and columns where the data type matches char, varchar, nvarchar, text, ntext, or uniqueidentifier.
  2. Object Existence Check:
    • It uses OBJECT_ID to ensure tables exist before querying them, avoiding errors from missing tables or views.
  3. Error Handling:
    • A TRY...CATCH block ensures that any errors (e.g., syntax issues or inaccessible tables) are safely ignored.
  4. Safe Execution:
    • The script avoids invalid SQL by trimming trailing UNION ALL and skips non-existent objects.

Use Cases

  • Debugging: Locate specific data in a large database.
  • Data Migration: Identify where specific values are stored for migration.
  • Auditing: Ensure sensitive information is properly stored.

How Automating Web Browsers with Selenium and C# in VS Code using Cursor with Command

Web automation is now a cornerstone in software testing and task scripting, allowing developers and testers to simulate user behavior, perform regression testing, and automate repetitive actions. One of the most powerful tools for browser automation is Selenium, and with the rise of cross-platform development, many are now using C# in Visual Studio Code (VS Code) to build these solutions.

In this blog, we’ll walk through how to set up and use Selenium with C# in VS Code, and execute browser commands programmatically using Cursor to mimic user interactions.

Why Selenium with C#?

Selenium supports multiple programming languages, but C# offers robust object-oriented support, great performance, and a rich ecosystem with .NET. It’s a preferred choice in enterprises and QA teams familiar with Microsoft technologies.

Benefits of using C# with Selenium:

  • Full .NET Core compatibility for cross-platform automation
  • Rich LINQ support for manipulating test data

Prerequisites

Before jumping into code, ensure you have the following installed:

Step-by-Step Setup

1. Create a New Console App

dotnet new console -n SeleniumAutomation
cd SeleniumAutomation

2. Add Selenium WebDriver NuGet Packages

Use the following commands to install necessary libraries:

dotnet add package Selenium.WebDriver
dotnet add package Selenium.WebDriver.ChromeDriver
dotnet add package Selenium.Support

3. Code: Launching and Controlling Browser

Open the Program.cs file and write the following code:

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using System;
using System.Threading;

class Program
{
    static void Main(string[] args)
    {
        ChromeOptions options = new ChromeOptions();
        options.AddArgument("--start-maximized");  // Open browser in maximized mode
        using IWebDriver driver = new ChromeDriver(options);

        driver.Navigate().GoToUrl("https://www.google.com");
        Thread.Sleep(2000); // Wait for 2 seconds

        IWebElement searchBox = driver.FindElement(By.Name("q"));
        searchBox.SendKeys("Selenium WebDriver with C#");
        searchBox.SendKeys(Keys.Enter);

        Thread.Sleep(4000); // View results

        driver.Quit(); // Close browser
    }
}

Using Cursor Commands to Simulate Human-Like Actions

For more realistic user interaction, we can control the cursor or mouse pointer using external libraries like InputSimulator or native Windows API wrappers. Here’s an example using the System.Windows.Forms.Cursor for simple movement (only works on Windows):

Add Reference

dotnet add package System.Windows.Forms

Simulate Cursor Movement

using System.Windows.Forms;
using System.Drawing;

class CursorDemo
{
    public static void MoveCursor()
    {
        // Move the cursor to a specific location (x:100, y:200)
        Cursor.Position = new Point(100, 200);
        Console.WriteLine("Cursor moved to (100, 200)");
    }
}

Automating Clicks Using JavaScript with Selenium

You can also execute mouse-like interactions via JavaScript when real cursor movement isn’t necessary:

IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
js.ExecuteScript("document.querySelector('input[name=q]').click();");

Running and Debugging in VS Code

To run the project in VS Code:

  1. Open your project folder in VS Code.
  2. Press Ctrl + Shift + P, select .NET: Generate Assets for Build and Debug.
  3. Press F5 to build and run the application.
  4. The browser should launch and perform the automated actions.

Tips for Effective Browser Automation

  • Always wait for elements to be visible using WebDriverWait or ExpectedConditions.
  • Handle exceptions to prevent hanging browsers.
  • Use headless mode for CI/CD environments:
options.AddArgument("--headless");
  • Log your test steps using Console.WriteLine() or integrate with logging frameworks.

Conclusion

Automating browsers with Selenium and C# in VS Code is a powerful way to streamline testing and repetitive tasks. With cursor control, you can simulate real user actions and make your automation scripts more interactive. Whether you’re automating form submissions, scraping data, or testing web apps, this setup gives you all the flexibility you need in a lightweight and efficient environment.

Why Software Testing is the Backbone of Successful Tech Companies

More and more technological focus is on software and practically every business and industry today have software at its core. Companies ranging from those in the finance sector, or even healthcare, and extending to e-commerce and education sectors are relying more and more on complex and efficient software systems to be able to use their resources effectively, create value for their clients, and be competitive on the market. Still, in spite of the many benefits that software offers, there are some down sides especially if the software is inadequately tested. Repercussions face businesses due to bugs, security holes, performance issues and other disruptive factors. This is the reason why software testing has become the lifeline and the Most Important Function of Tech Companies It Ensured the reliability of products and their competitive position with regard to the quality of the user experience.

Preventing Catastrophic Failures

A major responsibility that software testers must take up is to ensure that any form of deviation or defect is rectified before the software is deployed. One software bug can create chaos and lead to loss of money, loss of image, and may even lead to costly lawsuits. For instance, in 2012, a software bug at Knight Capital Group made the company lose 440 million dollars within a span of just 45 minutes, which almost brought the firm to its knees. Also, a similar lack of attention to software in the healthcare industry can cause fatalities by making unsubstantiated proposals on treatments or even miss critical medical conditions. These are among the things that make companies look the other way when it comes to making cuts on testing.

Problems of this type can be avoided in the first place by testing various properties early in the software development process. It makes certain that the systems perform as expected in a variety of situations and circumstances. For technology firms, user-initiated disruptions are not only futile, but also undesirable if continuity of customer trust is to be maintained, which in turn lends itself to competitiveness against other firms as well as maximizing overall revenue.

Enhancing User Experience (UX)

As the world is becoming a global marketplace, user experience (UX) has become the most important key competitive advantage for any online business. Today’s consumers will leave applications, sites, or platforms that perform even a tad slow, have bugs, or are cumbersome to use in a heartbeat. This is where software testing comes in. It guarantees that the applications perform within acceptable limits, are usable on different devices and are usable in smooth ways.

Usability testing is among the biggest ways targeted at making sure that the software is the right fit for the targeted users. This helps companies discover and adjust any design or navigation problems that would irritate users or affect their experience. Also, performance testing also assesses the way the application behaves under a heavy load, in order to make sure that it will withstand the highest volume of use. All these tests help in building up the user-friendly components of a product leading to increased user retention and customer loyalty as well.

Supporting Agile and DevOps Methodologies

There is an increase in the implementation of both Agile and DevOps as methods of development in the tech firms. Especially, these methodologies include building and deploying applications incrementally through constant refinement and relentless deployment. Nevertheless, without constant verification and validation, it would be close to impossible to keep the quality of software in such a velocity-oriented environment.

Testing is there in the whole life cycle of development in practice and DevOps. Various tools for conducting tests automatically check the effectiveness of the new code, evaluate the code for faults, and verify that the added features do not interfere with any of the previous features. With this level of testing, companies can release more updates frequently while maintaining the quality level. It also allows them to accommodate customer requirements quickly thus improving the development time.

Ensuring Security in an Increasingly Digital World

The increasing inter-connectedness of the world has exposed software companies to security threats and as such, the security concerns keep changing. Information security breaches can result in great risks like compromising large amounts of data, exposing very private data to unauthorized people and the strenuous process to repair the damage done to the corporation’s reputation. Hence, this leads to Security testing being recognized as an essential part of the overall comprehensive testing process.

Security testing confirms the prevention of such defects in the software system, which can open up certain user’s vulnerabilities to external people with malicious aspirations. And, it provides measures to ensure sensitive information security, correct enforcement of user permissions, and protection against hacking attacks in the systems. For technology companies, the requirement for such analysis is not only the safety of users – it is rather fundamental for the security of the organization itself and for foreseeing such damaging things as legal consequence as a result of data leakage.

Reducing Long-Term Costs

Towards this goal, some companies take it as an unnecessary cost, Jeanie Noe Pahutan asserts that the opposite is true. This is why it is vital to deal with a defect as early as possible during the software lifecycle. Studies show that the cost of adjusting post-verification errors can rise to 30 times more than appropriating these errors as they occur in the coding activity. A reason for this is that such problems are usually at the later stages of the cycle, which usually leads to having to change several stages that come after it, which makes the development and release of the product take longer than planned.

Testing helps prevent companies from releasing products with bugs and later putting up very extravagant and unnecessary post-release patching or emergency bug fixing. Also, it lessens the amount of support and maintenance that will be needed once the product has been released to its intended users. In the end, testing helps achieve the objectives of the technology companies as they are able to release high quality software without having to keep spending resources in correcting errors.

Driving Innovation with Confidence

At last, let us look at one more aspect that is so often underappreciated – software testing and its contribution to innovation. If companies are confident with the stability and security of the prolusion software, they are able to extend the limits, so to say. New features or new technologies can be tested by developers without a fear of causing a disruptive change. Testing offers a cushion that gives companies the ability to be very aggressive on innovation and yet ensure quality.

The process of testing has also become highly effective and extensive with the introduction of test automation. As opposed to state manual testing where only a limited number of tests can be performed, automated testing can achieve this within a number of minutes due to the fact that pre-scripted tests are controlled by a program which also gives a result. This enables technology firms to continue living with the reality of ever achieve enhancement of their systems by releasing novel modifications sequentially in constant terms to outpace their rivals.

Conclusion

Testing software cannot be viewed merely as a process of performing many chores — it is an activity that determines how successful tech companies will be. It avoids expensive mistakes and poor usability, embraces Agile and DevOps processes, secures systems and promotes creativity. In the business where the pace, consistency, and users’ trust matter most — software testing is a core practice that focuses on the long-term health of the business. Businesses that choose to adopt an effective test strategy would not only mitigate risks but also create an opportunity that will better their prospects and foster creativity.

Security Testing for Critical Systems in Software Testing

Introduction:

In today’s increasingly interconnected world, software systems are central to the functioning of businesses, governments, and industries. Many of these systems, such as financial applications, healthcare systems, defense technologies, and critical infrastructure, handle sensitive data or control essential processes. For such systems, security is paramount. A security breach can lead to data loss, financial damage, compromised operations, or even loss of life. Therefore, ensuring the security of critical systems through rigorous testing is an essential component of the software development lifecycle.

What is Security Testing?

Security testing is the process of evaluating a software application or system to identify vulnerabilities, weaknesses, or threats that could lead to unauthorized access, data leakage, or manipulation. It aims to protect the system from malicious attacks, prevent data breaches, and ensure that sensitive information remains secure.

Security testing for critical systems involves assessing how the software behaves in the presence of malicious actors, incorrect usage, or unexpected inputs, and ensuring that the system meets required security standards and compliance regulations.

Key Objectives of Security Testing for Critical Systems:

  1. Identify Vulnerabilities: Detect flaws or weaknesses that could potentially be exploited by attackers. These vulnerabilities may exist in the software, system architecture, or its integration with other systems.
  2. Ensure Data Protection: Critical systems often handle sensitive information. Security testing ensures that data privacy measures are in place and that information is encrypted, masked, or securely stored.
  3. Verify Authentication and Authorization: Strong mechanisms for user authentication and authorization are vital for preventing unauthorized access to critical systems. Security testing ensures that only authorized users can access sensitive parts of the system.
  4. Detect and Mitigate Threats: Identify potential threats, including common attack methods such as SQL injection, cross-site scripting (XSS), and denial-of-service (DoS) attacks. The goal is to ensure that the system is resilient to such threats.
  5. Compliance with Regulations: Many critical systems are subject to industry-specific regulations, such as HIPAA (for healthcare), GDPR (for data privacy), or PCI-DSS (for payment systems). Security testing ensures that the system complies with these standards.

Types of Security Testing for Critical Systems:

  1. Vulnerability Scanning: Automated tools are used to scan the system for known vulnerabilities. These tools compare the system’s components against a database of known security flaws and provide insights into any potential weaknesses.
  2. Penetration Testing (Pen Test): Penetration testing involves simulating real-world cyber-attacks to identify exploitable vulnerabilities. Ethical hackers (or penetration testers) attempt to gain unauthorized access to the system by exploiting weaknesses in its design, implementation, or configuration.
  3. Static Application Security Testing (SAST): SAST involves reviewing the source code of the application without executing it. It identifies vulnerabilities at the code level, such as insecure coding practices, poor input validation, or missing security controls.
  4. Dynamic Application Security Testing (DAST): DAST is performed while the application is running. It focuses on identifying vulnerabilities that occur during the operation of the application, such as improper handling of user inputs or weak session management.
  5. Threat Modeling: Threat modeling helps identify potential security risks early in the software design phase. This involves analyzing how an attacker might exploit weaknesses and how various parts of the system might be targeted.
  6. Security Code Review: A manual or automated review of the application’s code to detect any weaknesses or flaws related to security. This often includes checking for issues such as poor input validation, hardcoded passwords, or insufficient data encryption.
  7. Risk Assessment: Risk assessments identify potential security threats based on system architecture, external threats, and business impact. This includes determining the likelihood of attacks and the impact of those attacks on the organization’s operations.

Best Practices for Security Testing in Critical Systems:

  1. Shift Left Security: Security testing should start early in the development lifecycle, not just during the testing phase. Integrating security into the DevOps process (DevSecOps) ensures that security is embedded throughout the design, development, and deployment stages.
  2. Continuous Security Testing: Security testing shouldn’t be a one-time event but an ongoing process. With the rapid pace of new threats and vulnerabilities emerging daily, continuous testing and monitoring of the system’s security posture is critical.
  3. Use of Automation Tools: While manual penetration testing and code reviews are essential, automated tools can significantly enhance the speed and thoroughness of security testing. Tools like OWASP ZAP, Nessus, and Burp Suite can automate common security tests.
  4. Security Awareness and Training: Developers, testers, and other stakeholders involved in critical systems should be trained to understand common security risks and how to avoid them. This includes recognizing common attack vectors and following best security practices during development.
  5. Patch Management: Vulnerabilities in critical systems often arise from outdated software or libraries. Regular patch management and updates ensure that known vulnerabilities are addressed and patched promptly.
  6. Simulation of Real-World Attacks: Use red teams (simulated adversarial attackers) to conduct security exercises that mimic real-world attacks. These exercises help assess the effectiveness of security controls, the response to incidents, and the ability to mitigate breaches.
  7. Zero Trust Architecture: In a zero-trust model, no user or system is trusted by default, even if they are inside the corporate network. Implementing zero trust in critical systems ensures that every access request is verified and validated, reducing the risk of internal or external breaches.
  8. Logging and Monitoring: Critical systems must have comprehensive logging and monitoring mechanisms in place to detect suspicious activities in real time. Security testing should verify the effectiveness of these mechanisms in identifying and responding to threats quickly.
  9. Incident Response and Recovery Planning: Security testing for critical systems should also assess the system’s ability to respond to security incidents. This includes verifying incident response procedures and the robustness of disaster recovery and business continuity plans.

Challenges in Security Testing for Critical Systems:

  1. Complexity: Critical systems are often large, complex, and interconnected with other systems, making it challenging to conduct exhaustive security testing.
  2. Evolving Threats: The landscape of cybersecurity threats is constantly changing, and new attack methods are developed regularly. This requires continuous learning, adaptation, and testing.
  3. Resource Constraints: Comprehensive security testing can be resource-intensive. Many organizations may face budget or time constraints when trying to implement thorough security testing for critical systems.
  4. False Positives and Negatives: Security testing tools can sometimes produce false positives (indicating vulnerabilities where none exist) or false negatives (failing to detect actual vulnerabilities), requiring human intervention and expertise to interpret results correctly.

Conclusion:

Security testing for critical systems is a vital part of software testing. It ensures that software is resilient to cyber threats, protecting both sensitive data and the integrity of the system. Given the potential consequences of security failures, organizations must adopt a comprehensive and proactive approach to security testing, integrating it early into the development lifecycle, using the latest tools and techniques, and ensuring continuous monitoring. By doing so, they can minimize the risk of cyber-attacks, maintain the trust of their users, and meet regulatory compliance requirements, all while safeguarding the functionality and security of critical systems.
