在Unix / Linux中如何提取两个括号之间的单词？

缺口

我有一个SAS数据集，其中查询列表作为变量之一。以下是变量值之一：

SELECT * FROM ( SELECT Table1 file2.txt file.txt QUEUES QDefinitions
Parameters TRAP-Deposit-DSTran.dat.2016-08-07 FROM CS_CASE WHERE 
ANT_CD='FI_BASE_TENANT')t1 LEFT OUTER JOIN Table2 t2 ON 
t2.CASE_ID=t1.CASE_ID LEFT OUTER JOIN Table3 t3 ON 
t3.SERVICE_XID=t1.SERVICE_XID LEFT OUTER JOIN Table4 t4 ON 
t4.SERVICE_ID=t1.SERVICE_ID WHERE ( t1.CASESTATUs_CD = (NEW) OR 
t1.CASE_STATUS_CD = (OPEN) )
AND ( t3.SEARCH_VALUE = (HighVal_Ind) AND t3.SEARCH_VALUE_N <= 3 ) AND 
( t4.SEARCH_VALUE_Nm = (Curr_Strategy) AND t4.SEARCH_STRG = (095) ) 
GROUP BY t1.CASE_REFERENCE,t2.LAST_SCRFP,t1.SERVICE_ID 
ORDER BY t2.LAST_SCRFP DESC

我想要做的就是我想把值输入代码这里是在()为(' ')。

例如：

WHERE ( t1.CASESTATUs_CD = (NEW) OR t1.CASE_STATUS_CD = (OPEN) )

我想将其更改为：

WHERE ( t1.CASESTATUs_CD = ('NEW') OR t1.CASE_STATUS_CD = ('OPEN') )

我该怎么做？

您的问题尚不清楚，但也许这是您想要的：

$ sed -E 's/\(([^()]+)\)/('\''\1'\'')/g' file
SELECT * FROM ( SELECT Table1 file2.txt file.txt QUEUES QDefinitions
Parameters TRAP-Deposit-DSTran.dat.2016-08-07 FROM CS_CASE WHERE
ANT_CD='FI_BASE_TENANT')t1 LEFT OUTER JOIN Table2 t2 ON
t2.CASE_ID=t1.CASE_ID LEFT OUTER JOIN Table3 t3 ON
t3.SERVICE_XID=t1.SERVICE_XID LEFT OUTER JOIN Table4 t4 ON
t4.SERVICE_ID=t1.SERVICE_ID WHERE ( t1.CASESTATUs_CD = ('NEW') OR
t1.CASE_STATUS_CD = ('OPEN') )
AND ( t3.SEARCH_VALUE = ('HighVal_Ind') AND t3.SEARCH_VALUE_N <= 3 ) AND
( t4.SEARCH_VALUE_Nm = ('Curr_Strategy') AND t4.SEARCH_STRG = ('095') )
GROUP BY t1.CASE_REFERENCE,t2.LAST_SCRFP,t1.SERVICE_ID
ORDER BY t2.LAST_SCRFP DESC

上面是在此输入文件上运行的：

$ cat file
SELECT * FROM ( SELECT Table1 file2.txt file.txt QUEUES QDefinitions
Parameters TRAP-Deposit-DSTran.dat.2016-08-07 FROM CS_CASE WHERE
ANT_CD='FI_BASE_TENANT')t1 LEFT OUTER JOIN Table2 t2 ON
t2.CASE_ID=t1.CASE_ID LEFT OUTER JOIN Table3 t3 ON
t3.SERVICE_XID=t1.SERVICE_XID LEFT OUTER JOIN Table4 t4 ON
t4.SERVICE_ID=t1.SERVICE_ID WHERE ( t1.CASESTATUs_CD = (NEW) OR
t1.CASE_STATUS_CD = (OPEN) )
AND ( t3.SEARCH_VALUE = (HighVal_Ind) AND t3.SEARCH_VALUE_N <= 3 ) AND
( t4.SEARCH_VALUE_Nm = (Curr_Strategy) AND t4.SEARCH_STRG = (095) )
GROUP BY t1.CASE_REFERENCE,t2.LAST_SCRFP,t1.SERVICE_ID
ORDER BY t2.LAST_SCRFP DESC
