Question

我不确定我的语法是否正确。我所拥有的是一个查询，它将两个查询中的ID列为一个。我已经在表格之间建立了链接，以尽可能减少结果。

这是我必须使用的查询。我关注的两个列是SampleCode和Replicate。 http://tinypic.com/r/2ym5zt1/8

输出需要如何格式化就像这个例子（注意：在这种情况下，％只是一个地方填充物）：

C%    C%R
C%-1  C%-2
C%-1  C%-3
C%-2  C%-3
RL%   RLD%
RL%-1 RLD%-1

基本上，它将每个样本与其他样本进行比较。我已经尝试过滤器来缩小选择范围，但事情并没有正确排列。我曾尝试编写一个case语句但由于某种原因，THEN子句的语法似乎不起作用。只有C％R才有效。

CASE WHEN SAMPLES_1.SAMPLECODE LIKE 'C%R%' THEN LEFT(SAMPLES.SAMPLECODE,6)
     WHEN SAMPLES_1.SAMPLECODE LIKE 'RLD%' THEN SAMPLES.SAMPLECODE LIKE 'RL1%'
END

就RL而言，我不能使用精确的THEN语句，因为它可以是RL1％或RL1％-1。如果有办法通过SQL设置C％-1，C％-2 ......等，我宁愿这样做。但是，如果不可能，我将在Crystal Reports中对其进行格式化。

先谢谢。

这是查询

Answer 1

我不确定我是否完全理解这个问题，但语法不正确。您可以在LIKE之后使用WHEN，但不能在THEN之后使用CASE WHEN SAMPLES_1.SAMPLECODE LIKE 'C%R%' THEN LEFT(SAMPLES.SAMPLECODE, 6) WHEN SAMPLES_1.[REPLICATE] LIKE 'RLD%' -- Changed to the Replicate column THEN ( SELECT TOP 1 SAMPLECODE FROM dbo.Samples WHERE SAMPLECODE LIKE 'RL1%' ORDER BY SAMPLECODE ) END。

尝试使用子查询。如果您可以设置SQLFiddle，我们可以为您提供更好的帮助。

Answer 2

所以这个有点有趣了。我从原始查询中获取了输出。样本并没有像我报告所需要的那样排成一行。所以我在SQL中做了最小的过滤。我把查询带入水晶报告中并制作了一些公式来过滤其余的。它实际上比我想象的要容易。谢谢大家的建议。

在过滤结果后，使用LIKE的SQL Case语句
