Can you show DDL for table or view being used. Row count, and ideally a visual explain of the query that failed?

DDL:
CREATE TABLE "ABC"."E_SEGMENT_EVENT" (
            "CC_SEGMENT_ID" INTEGER NOT NULL,
            "EVNT_CODE" CHAR(4) NOT NULL,
            "SGEV_SEQ" INTEGER NOT NULL,
            "SGEV_SOM_HH" INTEGER,
            "SGEV_SOM_MM" INTEGER,
            "SGEV_SOM_SS" INTEGER,
            "SGEV_SOM_FF" INTEGER,
            "SGEV_CREATE_DATE" TIMESTAMP NOT NULL,
            "SGEV_CREATE_USER_ID" VARCHAR(10) NOT NULL,
            "EVNT_GROUP" INTEGER

In common case, the query not failed. but repeatedly run sometimes it will show this error. This error also show up in other DB2ResultSet.Read() or DB2ResultSet.ReadFirst()  function.

Hi Best,

Does the query always fail or is the failure intermittent?
Is Common.DataHelper a standard package or something that your shop has developed?


Following the stack trace, ObjRs.Read() calls IBM.Data.DB2.DB2ResultSet.Read() and the exception is occurring in FetchScroll.

Has the database connection been opened prior to this function is called?  
Do you know if ObjRs is using SQLCA or trying to manage its own cursor?
