我從數據庫中檢索一些行。例如,檢索後,我有兩行作爲有效載荷。我想在行內迭代。檢索到的兩行如下,在騾子的有效載荷中迭代
[{PAYLOAD_MSG=PU, SENSITIVEDATAINDICATOR=Y, ERRORMESSAGE=User generated exception test,
INTERFACEID=I0826, EXCEPTIONID=73, PAYLOADMSGID=I0826MessTesting0002, SEVERITY=2, INTERFACENAME=replay,
SOURCEPROTOCOL=MQ, CREATIONTIME=2016-03-01 08:29:36.211319, EVENTSOURCE=MQ_Input.transaction.Rollback},
{PAYLOAD_MSG=UvdjI, SENSITIVEDATAINDICATOR=N, ERRORMESSAGE=User generated exception test, INTERFACEID=I0826,
EXCEPTIONID=72, PAYLOADMSGID=I0826MessTesting0001, SEVERITY=2, INTERFACENAME=replay, SOURCEPROTOCOL=MQ,
CREATIONTIME=2016-03-01 08:29:36.211319, EVENTSOURCE=MQ_Input.transaction.Rollback}]
我想訪問第一行的Payload_Msg以及第二行。具體如何做到這一點?我試了下面的方法,
