I have to correct something I said before. I took the *AUTO out of the DIM(*AUTO:9999) keyword in the declaration and it still barfed the same message. So it has nothing to do with *AUTO.

Also, I have /exactly and precisely/ (redundant for emphasis) the same syntax in another regular *PGM program and it has been running smoothly for a long time.

What I don't get is how an SQL pre-compiler can get error out on a variable definition conflict when there is only one. (for the SQL statement variable used to "Prepare" the cursor.

definition conflict  two different definitions for something out of one definition.

Thanks, Charles!

I don't know whether it's relevant at this stage, but this all happens in the context of a service program procedure.

*SQL0314 Sev=35 Record=2297 Text = Position 40 Host variable QQSTMT not unique.*

*SQL5011 sev=30 Record=2301Text = Position 67 Host structure array MX not defined or not usable for reason code 1. *

In the calcs I build a dynamic SQL statement in variable QQSTMT to use in the normal SQL cursor.

==>As I wrote this I realized that it might be caused by the other error SQL0314.

BIG problem with SQL0314 is that I only find once that QQSTMT is defined. I suspect that issue is elsewhere but it gives me no clue.



*DCL-DS MX EXTNAME(CS58V004)DIM(9999) ;*




*2297 exec SQL Prepare STMT1 from :QQSTMT *


*exec SQL Declare M1 cursor for STMT1 ;;*


*exec SQL Open M1;*


*2301 exec SQL Fetch Next From M1 for :RowsToFetch rows into :MX ;*


P. S.I wrestled with the SQL5011 error before. Reading the text for it, looks like 12 different possible causes for it. The last time it happened for me I posted a please-help, but other changes in the code resolved the issue, and I couldn't figure out which change did it.

In coding a service procedure as a sort-of I/O server.

I have defined a data structure to receive rows from an SQL View:



This exact syntax works perfectly elsewhere without the *AUTO.

I'm getting error SQL5011  Host structure array MX not defined or not
usable for reason code 1.

Reason code 1: Host structure array not defined or is not a valid
structure. A valid structure must have at least one valid member....

Can somebody help or point me somewhere. I saw something similar before
so I suspect it's not the *AUTO throwing things off.
