Sql 选择中的位置（使用LISTAGG后）

我想从oracle数据库中的不同表运行此sql

表A装运线

表B=pckwrk

表C=invdtl

结果

---

在sql的这一部分中，其中a.wrkref=W00003DRHO'，“W00003DRHP select LISTAGGsubnum，”，“在来自invdtl的wrkrefsubnum的GROUPORDER内，”，其中a.wrkref中的wrkref是结果NULL，而不是S00004979333'，“S00004979346'，“S00004979358'，“S00004979365'，“SO0004979365”‌​S00004979369'，'S0000‌​4979375如何在value a.wrkref的开始和结束处添加单引号？我猜您正在尝试使用in谓词将字符串与子字符串匹配，只有在表达式相等时才能成功。试一试，演示

所以当INSTRa.wrkref，，，1=0时，替换CASE，然后。。。以

结果=正常 其他的 通过wrkrefsubnum在GROUPORDER中选择LISTAGGsubnum 来自invdtl 在a.wrkref中wrkref在哪里 a、 wrkref W00003DRHO'，'W00003DRHP result=NULL i nwant to add'for and after a.wrkref to get like'W00003DRHO'，'W00003DRHP'

结束

问题是什么？如果value a.werkref=W00003DRHO'，W00003DRHP是结果空值，而不是S00004979333'，S00004979346'，S00004979358'，S00004979365'，S00004979369'，S00004979375，请扩展您的问题。您如何无法从oracle数据库中的不同表运行此sql？在这部分sql中，a.wrkref=W00003DRHO'，“W00003DRHP select listagsubnum，，“GROUPORDER内，wrkrefsubnum from invdtl，其中a.wrkref中的wrkref为结果NULL，而不是S00004979333'，“S00004979346”，'S00004979358'、'S00004979365'、'S00004979369'、'S00004979375如何在ValueA.wrkref的开头和结尾添加单引号
