stmt − a statement handle, which was previously allocated by mysql_stmt_init(3). |
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.

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 |
