INSERT INTO `insert_table` (`datetime`, `uid`, `content`, `type`) 
    VALUES ('0', 'userid_0', 'content_0', 0);
INSERT INTO `insert_table` (`datetime`, `uid`, `content`, `type`) 
    VALUES ('1', 'userid_1', 'content_1', 1);

geändert in:

INSERT INTO `insert_table` (`datetime`, `uid`, `content`, `type`) 
    VALUES ('0', 'userid_0', 'content_0', 0), ('1', 'userid_1', 'content_1', 1);
