About

INSERT is one of the major keywords in SQL and has the function of inserting data into a table. It can optionally specify a list of columns to load into and a set of literal values (VALUES) or the results of a statement.

The syntax is of the form:

INSERT INTO [destination table] ([optional column list])
VALUES ([value list])

or

INSERT INTO [destination table] ([optional column list])
SELECT (select statement)

On some systems ( for example), the INTO is optional.

INSERT statements can be used to add multiple rows to a table at a time, and is preferable when loading bulk data instead of a single INSERT statement per row added. To do so, separate the ([value list]) with a comma:

INSERT INTO [destination table] ([optional column list])
VALUES ([value list]), [([value list]), ([value list]), ([value list])...]
