HISTORY_LOG_INFO() in SQLRPGLE

[Alan Addison]

I have an issue with using HISTORY_LOG_INFO from imbedded SQL. I consistently get from the pre-compiler:

Position 34 Variable RSET not defined or not usable.
Reason: A member of the host structure does not have an
equivalent SQL data type.

In the following code:

DDoIt S 256 Inz('select * -
D from table(-
D qsys2/history_log_info() ) -
D where message_id in (-
D ''CPF1124'', ''CPF1164'')')

Exec SQL Prepare SqlStmt from doIt ;
If SqlCode <> 0;
DsplText = 'SQL Prepare Error';
Dsply dsplText '' Answer;
*InLR = *On;
Return;
EndIf;
Exec SQL Declare C1 Cursor for SqlStmt;

Exec SQL Open C1;
If SqlCode <> 0;
DsplText = 'SQL Open Error';
Dsply dsplText '' Answer;
*InLR = *On;
Return;
EndIf;
DoU SqlCode <> 0 or @End;
Exec SQL Fetch C1 into :RSet;
If SqlCode = 0;

It is a pity that the above code didn't get formatted to be more readable...

RSet definition is from IBM: https://www.ibm.com/docs/en/i/7.2?to...table-function


Any comments/suggestions would be greatly appreciated.
