I am trying to insert multiple rows in a single insert query using host variable array in my application program IV2XVAL to improve the performance of my insert program. I am getting SQLCODE -310 in the insert query whereas I have checked that we are not passing any non-numeric data to decimal field.
When I looked for a resolution on google, I got a reference to www-01.ibm.com/support/docview.wss?uid=swg1PM21877 . It looks like it might not be due to application program and something to do with DB2 itself. Can you please have a look and help me out if possible.

Insert Query
Code:

      INSERT INTO VLXFS               
      (COMPANY_CODE         ,         
      MASTER_ID                    ,   
      VALUATION_DATE               ,   
      VALUATION_START_DATE         ,   
      SEQUENCE_NUMBER              ,   
      ENTRY_NUMBER                 ,   
      FUND_NUMBER                  ,   
      FUND_TYPE_INDICATOR          ,   
      FUND_DOLLARS                 ,   
      FUND_UNIT_VALUE              ,

I am getting SQLCODE -310 as below

SQLCODE -310
Decimal host variable or parameter 5 contains non-decimal data

I have checked all the parameters to insert query and there is no non-numeric data being moved to numeric field. Below is the snapshot from abend-aid with the values being passed to the failing insert query.

Shouldn't it be:
Code:
01  VALUE11-FUND-ARRAY.                                   
    05 COMPANY-CODE         PIC X(3)          OCCURS 999.                 
    05 MASTER-ID            PIC X(15)         OCCURS 999.
    05 VALUATION-DATE       PIC X(8)          OCCURS 999.                 
    05 VALUATION-START-DATE PIC X(8)          OCCURS 999.                 
    05 SEQUENCE-NUMBER      PIC S9(4)V COMP-3 OCCURS 999. 
and so on... ?

-310
What you posted link is from 2010-2011 and recent versions have all of them fixed for sure. So correct your SELECT query and make sure it matches up the host declarations and it has nothing to do with DB2 or system errors but the data itself. Did you check Host variable number or parameter number which is bad one in the SQLCA?

Marso, I think (not sure) when we use individual variables listed in INSERT or SELECT then occurs goes individually otherwise Group Occurs should work else TS would get different Sqlcode even before -310.

Thank you so much Marso.. It worked.. But performance didn't improved as expected for multi row insert v/s single row insert.

Code:
01  VALUE11-FUND-ARRAY.                                   
    05 COMPANY-CODE         PIC X(3)          OCCURS 999.                 
    05 MASTER-ID            PIC X(15)         OCCURS 999.
    05 VALUATION-DATE       PIC X(8)          OCCURS 999.                 
    05 VALUATION-START-DATE PIC X(8)          OCCURS 999.                 
    05 SEQUENCE-NUMBER      PIC S9(4)V COMP-3 OCCURS 999. 

and so on...

Coded for you - do it yourself next time

Performance may not improve as it is impacted by outside influences such as the number of other jobs accessing DB2 and other workload on the machine. You must remember that the same amount of DB activity takes place - you are simply making fewer calls to DB2.

If you have a really large number of rows to insert, you may increase performance by writing them to a temporary file and then doing a LOAD RESUME.
