Writing SQL test cases in English

Vexdata provides ability to write test cases in English which are converted to SQL.

SQL Rule

Write the test case in English in the AI Prompt section and click on Generate SQL.

Ensure that all the tables required for this test case are selected in the source section. This is necessary to generate SQL from English.

Our software enhances the ease and accuracy of data quality testing by allowing users to write test cases in natural language, powered by OpenAI. Below are examples to guide you in creating effective test cases for both single-table and multi-table test scripts.

Sample Data

1. Users Table

   user_id	name	age	credit_limit
   1	Alice	25	5000
   2	Bob	34	15000
   3	Charlie	29	7000

2. Orders Table

   order_id	user_id	order_amount	order_date
   101	1	300	2024-01-15
   102	2	2200	2024-01-18
   103	1	450	2024-02-05

English Inputs and Corresponding SQL

1. Validate that no users are underage

   • English: Ensure that all users are at least 18 years old in users table

   • SQL:

     SELECT * FROM Users WHERE age < 18;

2. Validate that no users are beyond retirement age

   • English: Check that no user is older than 65 in Users table.

   • SQL:

     SELECT * FROM Users WHERE age > 65;

3. Validate that all users have a positive credit limit

   • English: Confirm that every user has a credit limit greater than zero in users table.

   • SQL:

     SELECT * FROM Users WHERE credit_limit <= 0;

4. Ensure total orders do not exceed credit limits

   • English: Validate that the sum of order amounts for each user in Orders table does not exceed their credit limit in Users table.

   • SQL:

     SELECT u.user_id, u.name, SUM(o.order_amount) AS total_orders, u.credit_limit
     FROM Users u
     JOIN Orders o ON u.user_id = o.user_id
     GROUP BY u.user_id
     HAVING SUM(o.order_amount) > u.credit_limit;

5. Check for active users with no orders.

   • English: Identify users in users table who have not placed any orders.

   • SQL:

     SELECT u.user_id, u.name
     FROM Users u
     LEFT JOIN Orders o ON u.user_id = o.user_id
     WHERE o.order_id IS NULL;

These examples provide a clear demonstration of how English test case inputs can be translated into SQL queries to validate data across different scenarios in a database system.
