Inserting from the results of a MySQL SELECT

Posted by on November 7, 2011 in Database, MySQL | 0 comments

If you need a quick way to insert into another table from the results of a query, the best way would be to use the INSERT-SELECT Syntax. It’s quite simple.

INSERT INTO tableA (FieldA, FieldB) (SELECT FieldC, FieldD FROM tableB) ;

Note that field A & C and B & D should have the same data type. Using this method you can avoid any secondary programming language or loops to achieve your insert.
