Question

我有一个生成动态SQL的过程，在查询excel电子表格时会创建一个insert into语句。

可以将消息屏幕中的结果打印粘贴到ssms窗口并执行。当我尝试从存储过程中执行SQL时，我得到如下语法错误：

'SELECT  * into TestClient FROM OPENROWSET('Microsoft.ACE.OLEDB.12.0', 'Excel 12.0;HDR=YES;Database=G:\CustomerETL\Employee\PendingETL\ETLEmployeexls.xls;', [Sheet1$])'
Msg 102, Level 15, State 1, Line 15
Incorrect syntax near 'SELECT  * into TestClient FROM OPENROWSET('.

以下是整个存储过程。我知道问题出现在滴答声中（在创建动态SQL的SET块中，我只能找出丢失滴答的位置。

这是proc：

USE [ETL]
GO
/****** Object:  StoredProcedure [dbo].[ImportExcelSheetForCustomerEmployeeUpdate2]    Script Date: 12/19/2017 4:03:05 PM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[ImportExcelSheetForCustomerEmployeeUpdate2](@BatchID int)    

as

--EXEC ImportExcelSheetForCustomerEmployeeUpdate 2



/*  --  TRUNCATE TABLE FilesToImport
UPDATE FilesToImport

我发布这个作为答案，但它应该是评论。当我尝试将其添加为评论时StackOveflow一直认为我试图将@count添加为电子邮件目标。

在您的代码中：

WHILE @Count＆gt; 0 BEGIN

BEGIN

SELECT TOP 1 @FileID = FileID，@ USERFilename = ETLFilename，@ ClientName = ClientName ，@ FileType = FileType，@ ColCount = ColumnCount，@ RowToETL = RowsToETL FROM FilesToImport WHERE StatusID = 1 AND BatchID = @BatchID

END

您没有更新@count的值。这将永远不会循环或循环。您可能想要添加一个语句（在结束之前），例如：设置@count = @@ rowcount;
