I am new to MySQL. I would like to copy the content of one table to another table within the same database. Basically, I would like to insert to a table from another table.

Answer 1

INSERT INTO TARGET_TABLE SELECT * FROM SOURCE_TABLE;

EDIT: or if the tables have different structures you can also:

INSERT INTO TARGET_TABLE (`col1`,`col2`) SELECT `col1`,`col2` FROM SOURCE_TABLE;

EDIT: to constrain this..

INSERT INTO TARGET_TABLE (`col1_`,`col2_`) SELECT `col1`,`col2` FROM SOURCE_TABLE WHERE `foo`=1
