Question

请原谅任何措辞不好的问题，因为我对PL / SQL和Oracle的经验很少。但是，我目前不知道如何将表作为参数传递。目前，此过程输出与指定输入匹配的一个条目。例如，如果交易产品= a，交易区域= c，交易对象区域= b，交易台= d，交易法律实体= e，对冲产品= f且对冲法律实体= g，则返回此唯一组合。但是，我希望能够为每个参数分配多个值并返回所有结果。例如，根据前面的例子，如果我指定对冲法律实体= g或h，那么我希望看到2个条目 - ＆＃34; a，c，b，d，e，f，g＆＃34; AND＆＃34; a，c，b，d，e，f，h＆＃34;。我相信这是通过将我的参数类型更改为varchar2s表而不是单个varchar2来完成的。非常感谢任何见解。

如果我必须创建一个带有表名变量和OUT参数为SYS_REFCURSOR的过程，这就是我写它的方式。希望您可以根据代码进行调整。
