Using Embedded SQL

Hello:

I have a few questions using Embedded SQL in RPG ILE scenario. Say for
example: I have 2 files. File A is a control file and File B is a
transaction data file.


                        File B has 5 fields: BFIELD1   char    10
                                                   BFIELD2   char    10
                                                   BFIELD3   char    10
                                                   BFIELD4   char    10
                                                   BFIELD5   char    10

                        File A has 1 Field : AField      Char      10

Now the data in File A is: Record 1: BFIELD1
                                            2: BFIELD2
                                            3: BFIELD5

The data above in File A are the field names I want to select from File B.

ProgramX should read File A and build an dynamic SQL statement using the
data from File A. and then the execution of the SQL should result the data
from File B.

Can this be done using EMBEDDED SQL? If yes does any one have a sample code.


Thanks for your help in advance.
