QT mysql无法操作 [复制链接]

我连接MYSQL数据库显示可以连接上，但是对已连接上的数据库添加表，插入数据全部失败
create table: "cfg_trgops" "Table 'cfg_trgops' already exists QMYSQL: Unable to execute query"
"To DB add is error ! Using unsupported buffer type: -842150451 (parameter: 1) QMYSQL3: Unable to bind value"
"To DB add is error ! Using unsupported buffer type: -842150451 (parameter: 1) QMYSQL3: Unable to bind value"
"To DB add is error ! Using unsupported buffer type: -842150451 (parameter: 1) QMYSQL3: Unable to bind value"
"To DB add is error ! Using unsupported buffer type: -842150451 (parameter: 1) QMYSQL3: Unable to bind value"
"To DB add is error ! Using unsupported buffer type: -842150451 (parameter: 1) QMYSQL3: Unable to bind value"
"To DB add is error ! Using unsupported buffer type: -842150451 (parameter: 1) QMYSQL3: Unable to bind value"
"To DB add is error ! Using unsupported buffer type: -842150451 (parameter: 1) QMYSQL3: Unable to bind value"
这是什么原因？

有表了就不要添加了，要么添加一个不是cfg_trgops名字的表？

我删除掉了，就可以创建，但是之后的插入还是不行。。

不是有错误信息么，MySQL表存在不能添加啊。删除表'cfg_trgops'。

我用的是QT4.8.2是不是这个对编译器还有要求，还是对驱动有什么要求？
