c语言mysql数据库事务开始、提交、回滚范例_MySQL

memset ( sql, 0x00, sizeof( sql ) );

memcpy ( sql, "set autocommit=0;", 17 );

if( mysql_query( sock, sql ) ){

sprintf( g_acTrcMsg, "关闭自动提交模式失败[%d][%s]", mysql_errno( sock ), mysql_error( sock ) );TRCLOG1

return -1;

}

2、 事务开始

memset ( sql, 0x00, sizeof( sql ) );

memcpy ( sql, "start transaction;", 18 );

if( mysql_query( sock, sql ) ){

sprintf( g_acTrcMsg, "建立事务失败[%d][%s]", mysql_errno( sock ), mysql_error( sock ) );TRCLOG1

return -1;

}

3、 事务回滚

memset ( sql, 0x00, sizeof( sql ) );

memcpy ( sql, "rollback;", 9 );

if( mysql_query( sock, sql ) ){

sprintf( g_acTrcMsg, "事务回滚失败[%d][%s]", mysql_errno( sock ), mysql_error( sock ) );TRCLOG1

return -1;

}

4、 事务提交

memset ( sql, 0x00, sizeof( sql ) );

memcpy ( sql, "commit;", 7 );

if( mysql_query( sock, sql ) ){

sprintf( g_acTrcMsg, "提交事务失败[%d][%s]\n", mysql_errno( sock ), mysql_error( sock ) );TRCLOG1

return -1;
