Hello,

after having prepared statements containing parameters (e.g. "insert
into test (id, info) values (?,?)" or "select x, y where a = ? and b =
?") using the function mysql_stmt_prepare(), I can ask for the number of
parameters using mysql_stmt_param_count() and get the correct count.

But if I try to get details of the parameters using the funktion
mysql_stmt_param_metadata(), I always get NULL for the result.

My Environment: WinXP Prof. SP2, MySQL 5.0.13-rc-nt-max with
InnoDB-Tables, MS Visual C++ 6

Isn't the function mysql_stmt_param_metadata() implemented right now? -
Detail description in the manual says "to be added" but also "This
function was added in MySQL 4.1.2."


With best regards

Roland.

There's no description because it doesn't do anything yet.
