如何在 T-SQL 中专门使用 LIKE 查找特定符号+字符组合

Question

我有一些杂乱的数据需要清理，并且在其他模式匹配中，我正在尝试删除任何类似的内容：'-c[^ROAEH]'。

从另一个类似的问题，我试过：

SELECT *
FROM #AcctKeysInt
WHERE NewCustName LIKE '[!-c][^ROAEH]'
ESCAPE '!'

还有：

SELECT *
FROM #AcctKeysInt
WHERE NewCustName LIKE '[-c]%[^ROAEH]'

显然是常见的：

SELECT *
FROM #AcctKeysInt
WHERE NewCustName LIKE '[-]c[^ROAEH]'

和

SELECT *
FROM #AcctKeysInt
WHERE NewCustName LIKE '%[-]c[^ROAEH]'

基本上，我无法设法将连字符包含到字符搜索中，因为我得到的返回结果没有特别以“-c”开头的字符串。

我已经对该数据进行了其他模式匹配清理，其中找到了'-'，但是没有使用LIKE运算符，所以我想知道是否有LIKE 是一种方法吗？对于上下文，这里有一些其他模式匹配代码来清除我使用过的数据：

DROP TABLE IF EXISTS #AccountKeysCleansed;
SELECT strAcctNbrCurrent
       ,strAcctNbrHistoric
       ,strCustName
       ,CustNameOld
       ,GarbageOld
       ,IntCustName
       ,IntGarbage
       ,CASE WHEN CHARINDEX('- c', IntCustName) > 0 THEN TRIM(LEFT(IntCustName, CHARINDEX('- c', IntCustName) - 1))
             WHEN CHARINDEX('-cl', IntCustName) > 0 THEN TRIM(LEFT(IntCustName, CHARINDEX('-cl', IntCustName) - 1))
             WHEN CHARINDEX('*CAS', IntCustName) > 0 THEN TRIM(LEFT(IntCustName, CHARINDEX('*CAS', IntCustName) - 1))
             WHEN CHARINDEX('*CLOS', IntCustName) > 0 THEN TRIM(LEFT(IntCustName, CHARINDEX('*CLOS', IntCustName) - 1))
             WHEN CHARINDEX('* CLOS', IntCustName) > 0 THEN TRIM(LEFT(IntCustName, CHARINDEX('* CLOS', IntCustName) - 1))
             WHEN CHARINDEX('-  cl', IntCustName) > 0 THEN TRIM(LEFT(IntCustName, CHARINDEX('-  cl', IntCustName) - 1))
             WHEN CHARINDEX('*pend CLOSE', IntCustName) > 0 THEN TRIM(LEFT(IntCustName, CHARINDEX('*pend CLOSE', IntCustName) - 1))
             WHEN CHARINDEX('- To CLOSE', IntCustName) > 0 THEN TRIM(LEFT(IntCustName, CHARINDEX('- To CLOSE', IntCustName) - 1))
             WHEN CHARINDEX('-To CLOSE', IntCustName) > 0 THEN TRIM(LEFT(IntCustName, CHARINDEX('-To CLOSE', IntCustName) - 1))
             WHEN CHARINDEX('-=CLOSE', IntCustName) > 0 THEN TRIM(LEFT(IntCustName, CHARINDEX('-=CLOSE', IntCustName) - 1))
             WHEN CHARINDEX('(CLOSE',IntCustName) > 0 THEN TRIM(LEFT(IntCustName, CHARINDEX('(CLOSE', IntCustName) - 1))
             WHEN CHARINDEX('*deceas',IntCustName) > 0 THEN TRIM(LEFT(IntCustName, CHARINDEX('*deceas', IntCustName) - 1))
             WHEN CHARINDEX('-deceas',IntCustName) > 0 THEN TRIM(LEFT(IntCustName, CHARINDEX('-deceas', IntCustName) - 1))
             WHEN CHARINDEX('*legal',IntCustName) > 0 THEN TRIM(LEFT(IntCustName, CHARINDEX('*legal', IntCustName) - 1))
             WHEN IntCustName LIKE '*%' THEN RIGHT(IntCustName, LEN(IntCustName) - 1)
             ELSE IntCustName END NewCustName
       ,CASE WHEN CHARINDEX('- c', IntCustName) > 0 THEN RIGHT(IntCustName, LEN(IntCustName) - CHARINDEX('- c', IntCustName) + 1) + IntGarbage
             WHEN CHARINDEX('-cl', IntCustName) > 0 THEN RIGHT(IntCustName, LEN(IntCustName) - CHARINDEX('-cl', IntCustName) + 1) + IntGarbage
             WHEN CHARINDEX('*CAS', IntCustName) > 0 THEN RIGHT(IntCustName, LEN(IntCustName) - CHARINDEX('*CAS', IntCustName) + 1) + IntGarbage
             WHEN CHARINDEX('*CLOS', IntCustName) > 0 THEN RIGHT(IntCustName, LEN(IntCustName) - CHARINDEX('*CLOS', IntCustName) + 1) + IntGarbage
             WHEN CHARINDEX('* CLOS', IntCustName) > 0 THEN RIGHT(IntCustName, LEN(IntCustName) - CHARINDEX('* CLOS', IntCustName) + 1) + IntGarbage
             WHEN CHARINDEX('-  cl', IntCustName) > 0 THEN RIGHT(IntCustName, LEN(IntCustName) - CHARINDEX('-  cl', IntCustName) + 1) + IntGarbage
             WHEN CHARINDEX('*pend CLOSE', IntCustName) > 0 THEN RIGHT(IntCustName, LEN(IntCustName) - CHARINDEX('*pend CLOSE', IntCustName) + 1) + IntGarbage
             WHEN CHARINDEX('- To CLOSE', IntCustName) > 0 THEN RIGHT(IntCustName, LEN(IntCustName) - CHARINDEX('- To CLOSE', IntCustName) + 1) + IntGarbage
             WHEN CHARINDEX('-To CLOSE', IntCustName) > 0 THEN RIGHT(IntCustName, LEN(IntCustName) - CHARINDEX('-To CLOSE', IntCustName) + 1) + IntGarbage
             WHEN CHARINDEX('-=CLOSE', IntCustName) > 0 THEN RIGHT(IntCustName, LEN(IntCustName) - CHARINDEX('-=CLOSE', IntCustName) + 1) + IntGarbage
             WHEN CHARINDEX('(CLOSE', IntCustName) > 0 THEN RIGHT(IntCustName, LEN(IntCustName) - CHARINDEX('(CLOSE', IntCustName) + 1) + IntGarbage
             WHEN CHARINDEX('*deceas',IntCustName) > 0 THEN RIGHT(IntCustName, LEN(IntCustName) - CHARINDEX('*deceas', IntCustName) + 1) + IntGarbage
             WHEN CHARINDEX('-deceas',IntCustName) > 0 THEN RIGHT(IntCustName, LEN(IntCustName) - CHARINDEX('-deceas', IntCustName) + 1) + IntGarbage
             WHEN CHARINDEX('*legal',IntCustName) > 0 THEN RIGHT(IntCustName, LEN(IntCustName) - CHARINDEX('*legal', IntCustName) + 1) + IntGarbage
             WHEN IntCustName LIKE '*%' THEN '*' + IntGarbage
             ELSE IntGarbage END newGarbage
INTO   #AccountKeysCleansed
FROM   #AccountKeysInt;

举个例子，我试图清除的一些用户名的名称如下：

“名字姓氏-cro”
“随机名称 cah”
“RandomName-caird”
“姓名-通用-姓氏-coh” ... 等等。所以我希望 SQL 找到“-c[ROAEH]”，然后将“-”右边的任何内容添加到（列）垃圾堆中。

你知道我如何使用 LIKE 运算符做到这一点吗？

Answer 1

您似乎在寻找模式“%-c[roaeh]%”

SELECT *
FROM #AcctKeysInt
WHERE NewCustName LIKE '%-c[roaeh]%'

这种模式也适用于 PATINDEX

PATINDEX('%-c[roaeh]%', IntCustName)
