mysql_stmt_fetch - Fetches result set row from a prepared statement
#include <mysql.h> int mysql_stmt_fetch(MYSQL_STMT * stmt);
Fetch the result from a prepared statement into the buffer bound by [mysql_stmt_bind_result()}(mysql_stmt_bind_result).
stmt- a statement handle, which was previously allocated by mysql_stmt_init(3).
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_stmt_bind_result(3), mysql_stmt_execute(3), mysql_stmt_fetch_column(3), mysql_stmt_result_metadata(3), mysql_stmt_store_result(3).
