Name
mysql_stmt_result_metadata - Returns result set metadata from a pre-
pared statement.
Synopsis
#include <mysql.h>
MYSQL_RES * mysql_stmt_result_metadata(MYSQL_STMT * stmt);
Description
If a statement passed to mysql_stmt_prepare(3) 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.
Parameter
• stmt - a statement handle, which was previously allocated by
mysql_stmt_init(3).
Return value
Returns a result set that can be used to process metadata information.
Notes
• The result set returned by mysql_stmt_result_metadata() contains only
metadata. It does not contain any row results. The rows are ob-
tained by mysql_stmt_fetch(3).
• This result set pointer can be passed as an argument to any of the
field-based functions that process result set metadata, such as:
mysql_num_fields(3), mysql_fetch_field(3), mysql_fetch_field_di-
rect(3), mysql_fetch_fields(3), mysql_field_count(3),
mysql_field_seek(3), mysql_field_tell(3), mysql_free_result(3)
