Name
mysql_stmt_fetch - Fetches result set row from a prepared statementSynopsis
-
#include <mysql.h> int mysql_stmt_fetch(MYSQL_STMT * stmt);
Description
Fetch the result from a prepared statement into the buffer bound by [mysql_stmt_bind_result()}(mysql_stmt_bind_result).Parameter
- •
- stmt - a statement handle, which was previously allocated by mysql_stmt_init(3).
Return value
Returns 0 for success, MYSQL_NO_DATA if the end of the result set has been reached, or MYSQL_DATA_TRUNCATION if one or more values are truncated.Notes
- •
- Note that all columns must be bound by the application before calling mysql_stmt_fetch().
- •
- Data are transferred unbuffered without calling mysql_stmt_store_result(3) which can decrease performance (but reduces memory cost).
- •
- Truncation reporting must be enabled by function mysql_optionsv(3) with option MYSQL_REPORT_DATA_TRUNCATION
