mariadb_stm...ecute_direct(3) MariaDB Connector/Cmariadb_stm...ecute_direct(3) Name mariadb_stmt_execute_direct - prepares and executes a prepared state- ment Synopsis #include <mysql.h> int mariadb_stmt_execute_direct(MYSQL_STMT * stmt, const char *query, size_t length); Description Prepares and executes a statement which was previously allocated by mysql_stmt_init(3), using the current values of the parameter variables if any parameters exist in the statement. Parameters • stmt - A statement handle, which was previously allocated by mysql_stmt_init(3). • query SQL statement • length Length of SQL statement Return value Returns zero on success, non-zero on failure. Notes • Since the number of parameter of the statement is unknown before exe- cution it is mandatory to set the number of parameters via the mysql_stmt_attr_set(3) function. • If the SQL statement is a zero-terminated string, you can also pass -1 as length. • The statement handle is intended for one-time execution. Reusing the statement handle might lead to unexpected behavior. History This function was added in Connector/C 3.0 and requires MariaDB 10.2 or later versions. See Also • mysql_stmt_attr_set(3) • mysql_stmt_bind_param(3) Example ```C static int execute_direct_example(MYSQL mysql) { MYSQL_STMT stmt= mysql_stmt_init(mysql); MYSQL_BIND bind[2]; int intval= 1; int param_count= 2; char *strval= "execute_direct_example"; /* Direct execution without parameters */ if (mariadb_stmt_execute_di- rect(stmt, "CREATE TABLE execute_direct (a int, b varchar(30))", -1)) goto error; memset(&bind, 0, sizeof(MYSQL_BIND) * 2); bind[0].buffer_type= MYSQL_TYPE_SHORT; bind[0].buffer= &intval; bind[1].buffer_type= MYSQL_TYPE_STRING; bind[1].buffer= strval; bind[1].buffer_length= strlen(strval); /* set number of parameters */ if (mysql_stmt_attr_set(stmt, STMT_ATTR_PREBIND_PARAMS, ¶m_count)) goto error; /* bind parameters */ if (mysql_stmt_bind_param(stmt, bind)) goto er- ror; if (mariadb_stmt_execute_direct(stmt, "INSERT INTO execute_direct VAL- UES (?,?)", -1)) goto error; mysql_stmt_close(stmt); return 0; error: printf("Error: %s", mysql_stmt_error(stmt)); mysql_stmt_close(stmt); return 1; } Version 3.4 mariadb_stm...ecute_direct(3)
