Sql server 2008 从单个查询输出到多个文件

我有点困了。。。我试图从查询中获取输出，并根据单个条件将其分解为多个文件。我在将varchar类型转换为int时出错，我无法找出原因。正在SQL Server 2008中工作

DECLARE @LOOP AS INT;
DECLARE @SQL AS VARCHAR(MAX);
DECLARE @BCP AS VARCHAR(MAX);
DECLARE @COUNTER AS INT;
DECLARE @FILENAME AS VARCHAR(MAX);

SET @COUNTER='1'

SELECT @LOOP = COUNT(DISTINCT LIST_ID) FROM DATA_TABLE
WHERE STATUS='2' AND LIST_ID IS NOT NULL ;

SET @SQL=(SELECT CUSTOMER_NO FROM CUSTOMER A, DATA_TABLE B
WHERE A.CUSTOMER_ID=B.CUSTOMER_ID AND A.STATUS='2' AND LIST_ID='+@LOOP+');

SET @FILENAME='QUERYOUT C:\Projects\FILE_"'+@LOOP+'.TXT'

WHILE @COUNTER<=@LOOP
BEGIN
SELECT 
@BCP='BCP "'+@SQL+'+'+@FILENAME+''
SET @COUNTER=@COUNTER+1
END
GO

我试图使用循环值让我知道每个文件的内容。例如，LOOP='1'表示该文件包含与列表\u ID='1'关联的客户记录

关于这个错误的想法？

我不确定我是否完全理解您需要什么，但是如果您想为每个

列表ID发出BCP命令，您需要对它们进行循环并为每个执行

这可能不是你需要的，但与其等到我下班回家，我现在就发布它

DECLARE @FILENAME AS VARCHAR(MAX);
DECLARE @LISTID INT
DECLARE @LOOP AS INT;
DECLARE @BCP AS VARCHAR(MAX);
DECLARE @SQL AS VARCHAR(MAX);

DECLARE cur CURSOR FOR SELECT DISTINCT LIST_ID FROM DATA_TABLE WHERE STATUS='2' AND LIST_ID IS NOT NULL
OPEN cur

FETCH NEXT FROM cur INTO @LISTID

WHILE @@FETCH_STATUS = 0 BEGIN
    SET @FILENAME='QUERYOUT C:\Projects\FILE_'+Cast(@LISTID AS Varchar)+'.TXT -c -t -T'
    SET @SQL='(SELECT CUSTOMER_NO FROM CUSTOMER A, DATA_TABLE B WHERE A.CUSTOMER_ID=B.CUSTOMER_ID AND A.STATUS=''2'' AND LIST_ID='+@LISTID+')';
    SELECT @BCP='BCP '+@SQL+' '+@FILENAME+''
    EXEC xp_cmdshell @BCP
    FETCH NEXT FROM cur INTO @LISTID
END

CLOSE cur    
DEALLOCATE cur

1.将varchar（最大值）更改为varchar（8000）

2.为所有表添加DBNAME.SCHEMA，因为默认情况下它将指向主数据库。

在下面添加了双引号（“）

3.@FILENAME='QUERYOUT“C:\Projects\FILE_'+Cast（@LISTID AS Varchar）+'.TXT“-C-t-t'

4.“（“从客户A、数据表B中选择客户号，其中A.CUSTOMER\u ID=B.CUSTOMER\u ID和A.STATUS='2'，LIST\u ID='+@LISTID+'”）；
SET@FILENAME='QUERYOUT C:\Projects\FILE\u'+-CAST（@LOOP AS VARCHAR）+'.TXT”
DECLARE @FILENAME AS VARCHAR(MAX);
DECLARE @LISTID INT
DECLARE @LOOP AS INT;
DECLARE @BCP AS VARCHAR(MAX);
DECLARE @SQL AS VARCHAR(MAX);

DECLARE cur CURSOR FOR SELECT DISTINCT LIST_ID FROM DATA_TABLE WHERE STATUS='2' AND LIST_ID IS NOT NULL
OPEN cur

FETCH NEXT FROM cur INTO @LISTID

WHILE @@FETCH_STATUS = 0 BEGIN
    SET @FILENAME='QUERYOUT C:\Projects\FILE_'+Cast(@LISTID AS Varchar)+'.TXT -c -t -T'
    SET @SQL='(SELECT CUSTOMER_NO FROM CUSTOMER A, DATA_TABLE B WHERE A.CUSTOMER_ID=B.CUSTOMER_ID AND A.STATUS=''2'' AND LIST_ID='+@LISTID+')';
    SELECT @BCP='BCP '+@SQL+' '+@FILENAME+''
    EXEC xp_cmdshell @BCP
    FETCH NEXT FROM cur INTO @LISTID
END

CLOSE cur    
DEALLOCATE cur
