PDO Prepared Inserts multiple rows in single query

Question

I am currently using this type of SQL on MySQL to insert multiple rows of values in one single query:

INSERT INTO `tbl` (`key1`,`key2`) VALUES (\'r1v1\',\'r1         


        

Answer 1

That's simply not the way you use prepared statements.

It is perfectly okay to insert one row per query because you can execute one prepared statement multiple times with different parameters. In fact that is one of the greatest advantages as it allows you to insert you a great number of rows in an efficient, secure and comfortable manner.

So it maybe possible to implement the scheme you proposing, at least for a fixed number of rows, but it is almost guaranteed that this is not really what you want.
