mysql_stmt_fetch retrieves the next row from a prepared statement result set into the buffers bound by mysql_stmt_bind_result, returning MYSQL_NO_DATA at end of set.
int mysql_stmt_fetch(MYSQL_STMT * stmt);stmt - a statement handle, which was previously allocated by mysql_stmt_init().
Fetch the result from a prepared statement into the buffer bound by mysql_stmt_bind_result().
Returns 0 for success, MYSQL_NO_DATA if the end of the result set has been reached, or MYSQL_DATA_TRUNCATED 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() which can decrease performance (but reduces memory cost).
Truncation reporting must be enabled by function mysql_optionsv() with option MYSQL_REPORT_DATA_TRUNCATION
