Re: Soft coding SQL based on parameter file

Nope, just a typo.

Roger,

Assuming you used copy and paste for the code snippet, it looks like the definition for the RcdCount field has the letter "o" as the decimal places, instead of the number zero.

subject: Soft coding SQL based on parameter file

I have a need to soft-code SQL (embedded RPGLE) based on a parameter file for some auditing we need to do.  Record count and a couple of hash totals.

Table name will be passed as a parm to the program and it then looks up the columns it needs to query.

Configuration File Layout:     // Sample config
  Table_Name   10a                // SLP15
  Column1_Name   10a         // BBAL15
  Column2_Name   10a         // PTMT15
  Column1_Text  32a             // Customer Balance
  Column1_Text  32a             // Payment Amount

myDataStruct:         // Sample result data
  Name1   10a           //  BBAL15
  Name2   10a           //  PTMT15
  Text1      32a           //  "Customer Balance"
  Text2      32a           // "Payment Amount"
  Value1   31p2         //  10000.00
  Value2   31p2         // 2000.00
  RcdCount   10i o    // 4000

What I need is to be able to generate the equivalent of this based on and it is giving me fits:

select 'BBAL15', 'PTMT15', 'Customer Balance', 'Amount Paid', sum(BBAL15), sum(PTMT15), count(*) into myDataStruct  from SLP15

I've tried stringing it together with :HostVariable, using parameter markers, and nothing seems to work.   A lot of SQL0312 errors.

Does anyone have a simple example of this or pointers to get me going?  It's got to be the magic mix of literals and column names that is the problem.

Thanks.
