AND Operator

The AND operator is used to combine multiple conditions in a SQL query. All conditions must be true for the overall expression to be true.

Example: Using AND

SELECT Name
FROM FreedomFighters
WHERE City = 'Madurai' AND Contribution = 'Healthcare';

Output:

Returns the names of freedom fighters from Madurai who contributed to healthcare.

Do's and Don'ts

Do's

  • Use AND for precise filtering when multiple conditions must be met.
  • Test the query to ensure that all conditions are correctly combined.

Don'ts

  • Don't use AND if any of the conditions can be false; consider other operators.
  • Don't forget to use parentheses when combining AND with OR to control precedence.
