SET and SELECT in SQL
In SQL, the two most important statements for assigning variables are SET and SELECT. SET is used to assign single values efficiently, while SELECT is used to retrieve data and assign multiple values.
SET
SET is primarily used for assigning values to variables. It’s commonly employed within stored procedures, scripts, or batches to store a single scalar value.
Syntax:
SET @variable_name = expression;
SELECT
SELECT, on the other hand, serves a broader purpose. It retrieves data from one or more tables, views, or expressions, and it is not limited to assigning values to variables. It is a versatile command used for querying and returning result sets.
Syntax:
SELECT column1, column2, …
FROM table_name
WHERE condition;
