Question

我正在使用SQL Server 2005.我试图合并两行。

需要帮助才能排除身份编号和ApprovalCode NULL值。

SELECT DISTINCT CASE
                  WHEN (CONVERT(varchar(12), t1.referenceInfo)) like '1000%' THEN
                   (+ '"') + RTRIM(CONVERT(varchar(12), t1.referenceInfo)) + '"'
                  ELSE
                   '0'
                END AS [ identity number ],
                CASE
                  WHEN LEN(ISNUMERIC(CONVERT(varchar(12), t2.referenceInfo))) < 12 THEN
                   (+ '"') + RTRIM(CONVERT(varchar(12), t2.referenceInfo)) + '"'
                  WHEN (CONVERT(varchar(12), t2.referenceInfo)) LIKE '10%' THEN
                   (+ '"') + RTRIM(CONVERT(varchar(12), t2.referenceInfo)) + '"'  
                  ELSE
                   '0'
                END AS approvalcode
  FROM dbo.GUEST_CHECK_LINE_ITEM_HIST t1
 INNER JOIN dbo.GUEST_CHECK_LINE_ITEM_HIST t2
    ON t1.guestCheckID = t2.guestCheckID
 WHERE t1.guestCheckID = 78362401
   AND (t1.referenceInfo) LIKE '1000%'
  and (t2.referenceInfo) NOT LIKE '1000%'
  --AND LEN(ISNUMERIC(CONVERT(varchar(12), t2.referenceInfo))) < 12 
 GROUP BY t1.referenceInfo, t2.referenceInfo

参考表如下 http://postimg.org/image/45q41bogf/

我想将身份号码中10000％的值停放，并将批准代码中小于12位的值停放。如果批准代码少于12位，则为null。

感谢能否帮助我解决这个问题

Answer 1

尝试添加

HAVING [identity number] is not null and approvalcode is not null

Answer 2

尝试：

SELECT DISTINCT CASE
                  WHEN LEN(CONVERT(varchar(12), t1.referenceInfo)) > 11 THEN
                   (+ '"') + RTRIM(CONVERT(varchar(12), t1.referenceInfo)) + '"'
                  WHEN LEN(CONVERT(varchar(12), t2.referenceInfo)) > 11 THEN
                   (+ '"') + RTRIM(CONVERT(varchar(12), t2.referenceInfo)) + '"'
                  ELSE
                   '0'
                END AS [ identity number ],
                CASE
                  WHEN LEN(CONVERT(varchar(12), t1.referenceInfo)) < 12 THEN
                   (+ '"') + RTRIM(CONVERT(varchar(12), t1.referenceInfo)) + '"'
                  WHEN LEN(CONVERT(varchar(12), t2.referenceInfo)) < 12 THEN
                   (+ '"') + RTRIM(CONVERT(varchar(12), t2.referenceInfo)) + '"'
                  ELSE
                   '0'
                END AS approvalcode
  FROM dbo.GUEST_CHECK_LINE_ITEM_HIST t1
 INNER JOIN dbo.GUEST_CHECK_LINE_ITEM_HIST t2
    ON t1.guestCheckID = t2.guestCheckID
 WHERE t1.guestCheckID = 78362401
   AND t2.referenceInfo is not null
   and t1.referenceInfo is not null
 GROUP BY t1.referenceInfo, t2.referenceInfo

请注意，我更改了where子句的2行。看起来您使用了“＆lt;＆gt; 0”，您可能打算使用“is not null”。

SQL将两行合并为一行
