Question

我正在使用sql server 2005。我有以下字段名为referenceInfo。如果长度大于11，则为身份编号。如果长度小于12则是批准。

问题是它会跳到第二行。如何在同一行中制作它？

CASE
    WHEN LEN(CONVERT(varchar(12), GUEST_CHECK_LINE_ITEM_HIST.referenceInfo)) > 11 THEN (+'"') + RTRIM(CONVERT(varchar(12), GUEST_CHECK_LINE_ITEM_HIST.referenceInfo)) + '"'
    ELSE '""'
  END AS [Identity Number],
  CASE
    WHEN LEN(CONVERT(varchar(12), GUEST_CHECK_LINE_ITEM_HIST.referenceInfo)) < 12 THEN (+'"') + RTRIM(CONVERT(varchar(12), GUEST_CHECK_LINE_ITEM_HIST.referenceInfo)) + '"'
    ELSE '""'
  END AS [ApprovalCode]

我不确定，但似乎您正在尝试将两行合并为一行。既然你没有提供完整的sql，请尝试这样的事情（猜测ReceiptNo是唯一的）。这两个字段都需要t1或t2：

select all_other_fields
,      max(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 '""'
       end) as [identity number]
,      max(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 '""'
       end) as [approvalcode]
from   guest_check_line_item_hist t1
join   guest_check_line_item_hist t2
on     t1.ReceiptNo = t2.ReceiptNo
group
by     all_other_fields

SQL值不在同一行
