Re: Embedded SQL Select Into

Thanks Gary...LikeRec, eh? I would need an F spec in my program to identify
the record format I'm 'liking', right?

Michael,
Another example

* Start: data to store F/S Cashless Vend "Job" Info ----------------------
D job_MaxC C const(400)
max Jobs per Qry
D job_Max S 5I 0 Inz(job_MaxC)
" " " "
D job@ S 5I 0 Inz(0)
index to job#
D job_Rows S 5I 0 Inz(0)
rows from query

D job# DS DIM(job_MaxC) Qualified
D Fset 2A
Basis File Set
D SetLoc 4A
" Settlement Loc
D SetDat 7S 0
" " Date
D PrnNum 4A
Personnel/Driver Nbr
D BatNum 5S 0
" " Date
D JobNum 6S 0
" " Date
D RecSta 3S 0
Job Record Status
* End : data to store F/S Cashless Vend "Job" Info ----------------------

* Cursor to select Cashless Vend transactions to post
C/EXEC SQL
C+ DECLARE job_Csr CURSOR FOR
C+ SELECT DISTINCT fset, setloc, setdat, prnnum,
C+ 1 AS batnum, 0 AS jobnum, -- we will set these
values
C+ recsta
C+ FROM fspost
C+ WHERE recsta = 100
C+ ORDER BY 1,2,3,4
C/END-EXEC

C/EXEC SQL OPEN job_Csr
C/END-EXEC
C If SQLCODE <> *ZERO
Sql error
C LeaveSr
we're done for
C End

C/EXEC SQL
C+ FETCH job_Csr FOR :job_Max ROWS INTO :job#
C/END-EXEC
C Eval job_Rows = Sqler3
C If SQLCODE = *Zero And job_Rows >= job_Max
C LeaveSr
we're done for
C End

C SELECT
C When SQLCODE = *ZERO
* Have transactions to post: continue
C When SQLCODE = 100
* No transactions to post: exit
C LeaveSr


To create a DS based on a file, look at LIKEREC in your ILE RPG Language
Reference,
your D spec will look something like this:

D xids DS Likerec(XI01.XI01REC)
i/o buffer

I'd sure appreciate it. I'm trying to fetch rows into an externally
described data structure. I'm making this more difficult than it should be
I'll bet.

Note that your DS can be defined as a datastructure array - see post

You cannot do an array using into. Wish we could. You must define
a cursor, open and then do a fetch into for x rows and then close
cursor.

Also, you are going to have to have a data structure to read into.

Sigh...so I'm trying this:

Exec SQL
Select Session_Id Into :WkSession_ID
From MblSesP
Where Session_End is null;

I've defined Wk_Session_ID as:

D WkSession_ID S 128
D Dim(1000)

Note: I've also tried to define it as a data structure array (or
thought
I
did). I get an SQL0312 error - variable not found or unusable.

The definition of Session_ID (from DSPFFD) is:

SESSION_ID CHAR 128 130 43 Both
SESSION_ID
Variable length field -- Allocated length : None
Default value . . . . . . . . . . . . . . : None
Coded Character Set Identifier . . . . . : 37

Two questions: What am I doing wrong, and why does SQL hate me?

Thanks!
