if(@usertype> 0)
set @strSql= 'SELECT dbo.ayUser.UserID,dbo.ayUser.UserName,dbo.ayUser.UserEmail,dbo.ayUser.PassWordID, dbo.ayPassWord.ayPassWordID,dbo.ayPassWord.ayPassWord FROM dbo.ayPassWord INNER JOIN dbo.ayUser ON dbo.ayUser.PassWordID = dbo.ayPassWord.ayPassWordID where dbo.ayUser.username= '+@userinfo+ ' and dbo.ayPassWord.ayPassWord= '+@userpwd
else
set @strSql= 'SELECT dbo.ayUser.UserID,dbo.ayUser.UserName,dbo.ayUser.UserEmail,dbo.ayUser.PassWordID, dbo.ayPassWord.ayPassWordID,dbo.ayPassWord.ayPassWord FROM dbo.ayPassWord INNER JOIN dbo.ayUser ON dbo.ayUser.PassWordID = dbo.ayPassWord.ayPassWordID where dbo.ayUser.userEmail= '+@userinfo+ ' and dbo.ayPassWord.ayPassWord= '+@userpwd
EXECUTE sp_executesql @strSql
print @usertype
print @strSql
end
exec checkuser 1, 'ddd ', '123456 '
服务器: 消息 207，级别 16，状态 3，行 1
列名 'ddd ' 无效。
