主题：[求助]请教，如何获取SQL服务器所有表名？

1、Sel ect * From {订单} Where 实际的主键列名  Is Null

2、Sel ect * From {订单} Where 1=0

你可以动态生成一个临时表，即可获取表结构。

Dim cmd As new SQLCommand
cmd.CommandText = "Sel ect * From {表A} Where [_Identify] Is null"
cmd.C
Dim dt As DataTable = cmd.ExecuteReader
For Each dc As DataCol In dt.DataCols
    output.show(dc.name)
