What should you do after writing an SQL select query for a custom data set to ensure correctness?

Testing the SQL select query with the test button is essential for ensuring correctness because it allows you to execute the query in a controlled environment, confirming that it returns the expected results. This action helps identify syntax errors, logical flaws, or any misconfigurations in the query. By using the test feature, you can validate the functionality of the query against the data set it’s intended to work with, making necessary adjustments before finalizing it.

Other actions, while potentially beneficial for collaboration and review, do not directly assess the functionality of the query itself. For instance, submitting the query for review may not provide immediate feedback on its correctness, and while saving and running a query can confirm its execution, these steps may not include any pre-execution validation. Sharing with a team member for feedback can be valuable but does not replace the critical step of independently validating the query's correctness through testing.
