Question

在vb 里写的sql语句如何返回结果，如下段代码

txtsql = "BEGIN TRANSACTION "
txtsql = txtsql & "DECLARE @errorSum INT "
txtsql = txtsql & "SET @errorSum=0 "
txtsql = txtsql & "delete from 教课信息 "
txtsql = txtsql & "WHERE 编号=Text5.Text "
txtsql = txtsql & "SET @errorSum=@errorSum+@@error "

txtsql = txtsql & "IF @errorSum<>0 "
txtsql = txtsql & "BEGIN print '删除失败' "
txtsql = txtsql & "ROLLBACK TRANSACTION "
txtsql = txtsql & "END "
txtsql = txtsql & "ELSE BEGIN "
txtsql = txtsql & "print '删除成功' "
txtsql = txtsql & "COMMIT TRANSACTION "
txtsql = txtsql & "END "
ExecuteSQL (txtsql)

如何把“删除失败”“删除结果” 反映到vb界面的控件上，比如label，需要什么函数么？

少年，像你这样写语句就相当于把所有语句都写在一行上了，这样是不能被编译器准确编译的。还有把SQL语句嵌到VB中，你得先写好数据库连接语句，不然你写的语句再对也读取不到数据库数据不是。再看书研究一下吧
