SELECT Statement

The SELECT statement is the most commonly used command in SQL for retrieving data from one or more tables. It allows you to specify which columns to return in the query result.

Example: Basic SELECT Query

SELECT Name, City FROM FreedomFighters;

Output:

Returns the Name and City of all records in the FreedomFighters table.

Do's and Don'ts

Do's

  • Specify only the columns you need to optimize query performance.
  • Use meaningful aliases to make the result easier to understand.

Don'ts

  • Don't use SELECT * unless you need all columns, as it may impact performance.
  • Don't forget to test and optimize queries for large datasets.
