在我的工作中，我们的SQL Server版本是2012年，我相信，在2017版本中，现在有一个TRANSLATE命令。因为我们只有2012 SQL Server，所以我需要一些UPDATE和REPLACE的组合（REPLACE（REPLACE显然可以执行与一个TRANSLATE语句相同的操作。
我的表有一个SKU列，WebDescription列和一个HTML_WebDescription列。我的目标是在WebDescription中使用文本，并在必要时将其替换为和
标记，然后将其放在HTML_Column中。
到目前为止......我有：
UPDATE TableauWarehouse_Test.dbo.EntityAttributes_WebCoreInfo_WebDescription
SET HTML_WebDescription = '<p><strong>' +
REPLACE(REPLACE(REPLACE(WebCoreInfo_WebDescription, CHAR(13) + CHAR(10) +
CHAR(13) + CHAR(10),'</p>'+ CHAR(13) + CHAR(13) +'<p><strong>'),
CASE WHEN DIFFERENCE(CHAR(13),'.') <= 6 THEN '.' ELSE 'jfjdkfjsk' END,
'.</strong>'),
CASE WHEN DIFFERENCE('<strong>','<strong>') > 4 THEN '.</strong>' ELSE
'HFJKDJSK' END, '???')+ '</p>'
它返回：

我只需要正确关闭我的强力标签（即应用程序。）。现在它正在每个时期之后放置一个收盘强标签。
谢谢大家！
答案 0 :(得分：0)
T-SQL中的DIFFERENCE函数不是您所期望的，它与SOUNDEX函数有关。
要查找字符串中字符的位置，请使用CHARINDEX函数。
在这里，我在每行第一次出现一个点后添加了</strong>：
SELECT '<p><strong>'
+ LEFT(WebCoreInfo_WebDescription,ISNULL(NULLIF(CHARINDEX('.',WebCoreInfo_WebDescription),0),LEN(WebCoreInfo_WebDescription)))
+'</strong>' + ISNULL(SUBSTRING(WebCoreInfo_WebDescription,NULLIF(CHARINDEX('.',WebCoreInfo_WebDescription),0)+1,LEN(WebCoreInfo_WebDescription)),'')
+ '</p>'
FROM TableauWarehouse_Test.dbo.EntityAttributes_WebCoreInfo_WebDescription
我使用NULLIF函数来处理CHARINDEX返回0时的情况（当该行中没有点时）。
