What is the purpose of the SQL WHERE clause?

  • To delete rows
  • To filter rows based on a specified condition
  • To insert new rows
  • To update rows in a table
The SQL WHERE clause is used to filter rows from a table based on a specified condition. When querying a database, the WHERE clause allows you to specify criteria that the rows must meet to be included in the result set. This enables you to retrieve only the data that meets certain conditions, making queries more targeted and efficient. In the context of database testing, the WHERE clause is essential for selecting specific subsets of data for validation, ensuring that the test cases focus on the relevant portions of the database.
