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.
