mysql_stmt_result_metadata — Returns result set metadata from a prepared statement

MYSQL_RES * mysql_stmt_result_metadata(MYSQL_STMT * stmt);

If a statement passed to mysql_stmt_prepare() is one that produces a result set, mysql_stmt_result_metadata() returns the result set that can be used to process the meta information such as total number of fields and individual field information.

Parameters

stmt: A statement handle, which was previously allocated by mysql_stmt_init().

Return value

A result set containing field information for a result set
