Question

序言：我的SQL很基本。我从供应商处收到一个SQL查询，该查询从几个不同的数据库中选择并导出每个员工的注释和其他数据，并以CSV的形式导出为CSV，这是由他们编写的，但他们对此请求没有帮助。该查询提取了太多数据，从而使导入文件成为一个非常耗时的文件。因此，我想添加/修改查询以具有“ WHERE date> whatdate”以将我的结果缩小到最近的数据。例如，我只想拉出过去两天输入的评论。

我要为其添加子句的列是定义为datetime的列“ A.CMS502”。我相信这是此查询中唯一相关的列。此列中的日期示例为“ 2003-10-06 17：05：21.000”。如果有帮助，我正在使用SQL Server 2008。这可能吗？谢谢。

SELECT 
    'ID,Acct/LnNbr,NoteCreatedDate,CollectorId,ApplytoAll,Note'
UNION ALL
SELECT 
    ID + ',' + ID + ',' + NoteCreatedDate + ',' + CollectorId + ',' + 'No' + ',' + Note
FROM
    (SELECT 
         CASE WHEN SUBSTRING(A.CMS301,LEN(A.CMS301),1) = 'S' 
                 THEN SUBSTRING(A.CMS301,1,LEN(A.CMS301) - 1) 
                 ELSE A.CMS301 
         END + '-' + 
         CASE WHEN SUBSTRING(A.CMS301,LEN(A.CMS301),1) = 'S' 
                 THEN 'S' ELSE 'L'
         END AS [ID],
         REPLACE(CONVERT(VARCHAR, A.CMS501, 10), '-', '') AS [NoteCreatedDate],
         CASE WHEN U.CMS1201 IS NOT NULL 
                 THEN U.CMS1205 + ' ' + U.CMS1204 
                 ELSE (SELECT CMS1205 + ' ' + CMS1204 FROM sysUSER WHERE CMS1201 = 'PSUSER')
         END AS CollectorId,
         CAST(A.CMS512 AS NVARCHAR(MAX)) AS [Note]
     FROM 
         ACTIVITY AS A
     LEFT JOIN 
         sysUSER AS U ON A.CMS503 = U.CMS1201
     WHERE 
         A.CMS504 NOT IN (411,500,511,711,804,900,901,903,907,2000,999777)
         AND A.CMS504 NOT BETWEEN 1102 AND 1199) AS S

尝试一下，这将在最后2天输出。

SELECT 'ID,Acct/LnNbr,NoteCreatedDate,CollectorId,ApplytoAll,Note'
UNION ALL
SELECT ID + ',' + ID + ',' + NoteCreatedDate + ',' + CollectorId + ',' + 'No' + ',' + Note
FROM
(
SELECT CASE WHEN SUBSTRING(A.CMS301,LEN(A.CMS301),1) = 'S' THEN SUBSTRING(A.CMS301,1,LEN(A.CMS301) - 1) ELSE A.CMS301 END
+ '-' + CASE WHEN SUBSTRING(A.CMS301,LEN(A.CMS301),1) = 'S' THEN 'S' ELSE 'L'
END AS [ID]
,REPLACE(CONVERT(varchar,A.CMS501,10),'-','') AS [NoteCreatedDate]
,CASE WHEN U.CMS1201 IS NOT NULL THEN U.CMS1205 + ' ' + U.CMS1204 ELSE
(SELECT CMS1205 + ' ' + CMS1204 FROM sysUSER WHERE CMS1201 = 'PSUSER')
END AS CollectorId
,CAST(A.CMS512 AS nvarchar(max)) AS [Note]
FROM ACTIVITY AS A
LEFT JOIN sysUSER AS U
ON A.CMS503 = U.CMS1201
WHERE A.CMS504 NOT IN (411,500,511,711,804,900,901,903,907,2000,999777)
AND A.CMS504 NOT BETWEEN 1102 AND 1199

AND A.CMS502 >= DATEADD(D, -2, GETDATE())

) AS S

需要帮助在预写的SQL语句中添加WHERE子句
