我之前新建过这样一个标签，运行了几次后出的这个问题，之前前一直好好的，用了很久没问题：

SELECT     TOP (100) PERCENT dbo.KS_FormRecord47.item0 AS Expr4, dbo.KS_FormRecord47.item1 AS Expr5, dbo.KS_FormRecord43.RecordID, dbo.KS_FormRecord43.AddDate,
                      dbo.KS_FormRecord43.item6, dbo.KS_FormRecord43.item0, dbo.KS_FormRecord43.item9, dbo.KS_FormRecord43.item5, dbo.KS_FormRecord43.item7, dbo.KS_FormRecord43.item11,
                      dbo.KS_FormRecord44.item0 AS Expr1, dbo.KS_FormRecord44.item1, dbo.KS_FormRecord44.item4, dbo.KS_FormRecord44.item6 AS Expr2, dbo.KS_FormRecord44.item7 AS Expr3,
                      dbo.KS_FormRecord44.item3, dbo.KS_FormRecord45.item0 AS Expr6, dbo.KS_FormRecord45.item1 AS Expr7, dbo.KS_FormRecord46.item0 AS Expr8
FROM         dbo.KS_FormRecord43 INNER JOIN
                      dbo.KS_FormRecord44 ON dbo.KS_FormRecord43.RecordID = dbo.KS_FormRecord44.CopyNO INNER JOIN
                      dbo.KS_FormRecord47 ON dbo.KS_FormRecord43.RecordID = dbo.KS_FormRecord47.CopyNO INNER JOIN
                      dbo.KS_FormRecord45 ON dbo.KS_FormRecord43.RecordID = dbo.KS_FormRecord45.CopyNO INNER JOIN
                      dbo.KS_FormRecord46 ON dbo.KS_FormRecord43.RecordID = dbo.KS_FormRecord46.CopyNO
ORDER BY dbo.KS_FormRecord43.AddDate DESC
