The SELECT INTO statement is usually used to create backup copies of tables.
That also explain that SELECT INTO creates a new table and fills it with data computed by a query.
SELECT INTO syntax is:
SELECT [COLUMN NAME 1], [COLUMN NAME 2] ,...
INTO [BACKUP TABLE NAME]
FROM[TABLE NAME]
EXAMPLE 1 :
Let’s say we want to create a copy of the GameScores table and data.
SQL Statement:
SELECT * INTO GameScores_backup
FROM GameScores
SELECT INTO statement also can export the backup data to another database, let's see the example 2.
EXAMPLE 2 :
Let’s say we want to create a copy of the GameScores table and data to another database name backup_database.
SQL Statement:
SELECT * INTO GameScores_backup IN 'backup_database.mdb'
FROM GameScores
