Question

我正在编写一个sql查询来从我们的一个链接oracle服务器中提取一些数据。

此查询的唯一问题是两个日期添加行（删除了查询运行）但我需要他们的数据。

我收到以下错误： OLE DB提供商＆＃34; MSDAORA＆＃34;对于链接服务器＆＃34; MAGINUS＆＃34;返回消息＆＃34; ORA-00904：＆＃34; DATEADD＆＃34;：无效标识符

有人可以为这些规定语法吗？

提前致谢

System.out.println(count(a));

Dateadd对SQL Server有效，但是您发送到Oracle数据库的查询需要对oracle有效。因此，您需要将dateadd移到openquery之外，并进入SQL Server位：

DECLARE  @TSQL VARCHAR(8000)
    ,@CUSTOMER_ACCOUNT VARCHAR(20)

SELECT @TSQL1 = '
SELECT   CustomerAccount
        ,ContactName
        ,MembershipNumber
        ,ProductDescription
        ,DATEADD(SECOND, MembershipStartDate, ''19700101'')  AS MembershipStartDate
        ,DATEADD(SECOND, MemberhrshipEndDate, ''19700101'') AS MemberhrshipEndDate
        ,Price Paid
FROM OPENQUERY(MAGINUS,''
SELECT 
 CM.CUSTOMER_ACCOUNT  AS "CustomerAccount"
,CM.CONTACT_NAME      AS "ContactName"
,CM.MEMBERSHIP_NUMBER AS "MembershipNumber"
,P.LONG_DESCRIPTION_1 AS "ProductDescription"
,CM.MEMBERSHIP_START_DATE AS "MembershipStartDate"
,CM.MEMBERSHIP_EXPIRY_DATE AS "MemberhrshipEndDate"
,SH.ORDER_VALUE AS "Price Paid"
FROM MAGINUS.CUSTOMER_MEMBERSHIP CM 
INNER JOIN MAGINUS.PRODUCT  P 
ON CM.PRODUCT_CODE = P.PRODUCT_CODE
INNER JOIN MAGINUS.SALES_HEADER SH
ON CM.CUSTOMER_ACCOUNT = SH.CUSTOMER_ACCOUNT
AND CM.SALES_DOCUMENT_NUM = SH.SALES_DOCUMENT_NUM
WHERE CM.CUSTOMER_ACCOUNT = ''''' + @CUSTOMER_ACCOUNT + ''''''')'
EXEC (@TSQL1)
