I have a multi-segment RM COBOL file that is described like this:
01 MSVALU-REC.
05 MSVALU-KEY.
10 MSVALU-TYPE PIC X. 001
10 MSVALU-MODEL PIC X(12). 002
10 MSVALU-MODEL-ID PIC X. 014
10 MSVALU-REP-AREA PIC 999. 015
10 MSVALU-SEQ PIC 99. 018
05 MSVALU-MODEL-INFO.
10 MSVALU-MODEL-TABLE OCCURS 10 TIMES.
15 MSVALU-IDS PIC X.
15 MSVALU-IDS-TEXT PIC X(20).
10 FILLER PIC X.
05 MSVALU-AREA-INFO REDEFINES MSVALU-MODEL-INFO.
10 MSVALU-AREA-TABLE OCCURS 10 TIMES.
15 MSVALU-AREA PIC XXX.
15 MSVALU-AREA-TEXT PIC X(18).
10 FILLER PIC X.
05 MSVALU-COMP-INFO REDEFINES MSVALU-MODEL-INFO.
10 MSVALU-COMP-TABLE OCCURS 10 TIMES.
15 MSVALU-COMP PIC XXX.
15 MSVALU-COMP-TEXT PIC X(18).
10 FILLER PIC X.
When I attach to the associated .DAT file and query it, I get everything as a flat structure with the MSVALU-MODEL-INFO segment as one big (structured) string. Here are the results from:
SELECT * FROM MSVALU
MSVALU-TYPE MSVALU-MODEL MSVALU-MODEL-ID MSVALU-REP-AREA MSVALU-SEQ MSVALU-MODEL-TABLE
----------- ------------ --------------- --------------- ---------- ------------------
A CTS F 0 1 [[0,13PERIODIC MAINT. ],[null,null],[null,null],[null,null],[null,null],[null,null],[null,null],[null,null],[null,null],[null,null]]
C 1110C F 5 1 [[0,05COLD WEATHER START],[0,11RADIATOR & FAN SHR],[0,12FAN ],[0,15ENGINE SPEED CONTR],[0,21AIR CLEAN & PIPING],[0,31MUFFLER & EXHAUST ],[0,40ENGINE MOUNTING ],[0,61EX FUEL PUMP ],[0,63FUEL LINES & FIT ],[0,64FUEL TANK ]]
C 1110C F 7 1 [[0,52CLUTCH ELEMENTS ],[null,null],[null,null],[null,null],[null,null],[null,null],[null,null],[null,null],[null,null],[null,null]]
...
more rows...
...
Is there a way to select the lower segments (i.e. the MSVALU-MODEL-INFO or MSVALU-AREA-INFO ror MSVALU-COMP-INFO)? Something like:
SELECT * FROM MSVALU.MSVALU-MODEL-INFO
or
SELECT * FROM MSVALU/MSVALU-MODEL-INFO
or
SELECT * FROM MSVALU\MSVALU-MODEL-INFO
or
SELECT * FROM MSVALU[MSVALU-MODEL-INFO]
or
SELECT * FROM MSVALU-MODEL-INFO
(all of which I have tried)
I have also tried variants on reading just the defined structures as a column, like this:
SELECT "MSVALU-COMP-INFO" from MSVALU
And while this returns data, it does not look like just the particularly defined or redefined segments.
Any help would be appreciated.

Glenn

MSVALU-MODEL-INFO is a compound column, and you have some alias column too. It can not be take as table name. You can use those column names directly in your sql. For instance,
select "MSVALU-AREA-TEXT", "MSVALU-COMP-INFO","MSVALU-COMP-TABLE(3)","MSVALU-COMP-TABLE","MSVALU-COMP","MSVALU-SEQ" FROM MSVALU

Great. Thanks.
It would be nice if the JDBC exploration api actually showed that these values were there and the SELECT * would return them.

You wish a feature select * from MSVALU.MSVALU-MODEL-INFO
will show
MSVALU-MODEL-TABLE? but MSVALU-MODEL-TABLE is an array column
MSVALU-IDS(2), MSVALU-IDS-TEXT,MSVALU-IDS-TEXT(3), MSVALU-MODEL-TABLE,MSVALU-MODEL-TABLE(0) can be used in your sql.
Maybe you need a function,
For instance select top 1 subcolumnname('MSVALU-IDS') from MSVALU ?
