棘手的问题，大家可以讨论~~~~~~~~~~~~(200分)

分开运行没有问题，合起来运行就报错“access violation at address 4d9f562b in module'idodbc32.dll'”

没办法了，请各位帮忙看看

在每次CLEAR之前先CLOSE看看如何
不行的话单步调试一下这种问题一般并不难解决

用ADO试试

每次执行后
先DM1.Qtemp1.close;

别用try finally
改用try Except。

在Clear前应该先关闭打开的Qtemp1.Close;

TT , 我试过了，问题依旧，5~~~~~~~~~~~~~

你只是把query open不要execsql

sorry, 各位，原来是我DataBaseName 设置上出了一点问题。
问题已解决，各位把分平分了吧
