Reply with quote

How can I unload data from more than 1 DB2 table.
The selection creiterion is given as a SELECT query with union in the UNLOAD parameters as :

UNLOAD
UNLOADDN(SYSRE001)
SORTDEVT SYSDA
SELECT a, b,c
From table1
UNION
SELECT d,b,c
from table2,table1
where table1.b=table2.d and
table1.a=substr(d,1,3)
group by table1.a,b,c,d


It errors as "UNEXPECTED TOKEN "UNION' ENCOUNTERED'

NOTE: d is of 8 characters and a is of 3 characters

Ex: table1 -->
a b c
001 ab1 xyz
001 ab2 abc

table2: -->
d
ab100035
ab100050

Output should be like that :


a b c

001 ab1 xyz
001 ab100035 xyz
001 ab100050 xyz
001 ab2 abc

Try this setup and see if this works for you:


//STP0100 EXEC PGM=IKJEFT01,DYNAMNBR=20
//SYSREC00 DD DSN=Give dataset name for output raw data,
// DISP=(,CATLG,DELETE),
// UNIT=SYSDA,
// SPACE=(CYL,(1,99),RLSE),DCB=(MODEL.DSCB1,BLKSIZE=0)
//SYSPUNCH DD DUMMY
//SYSTSPRT DD SYSOUT=*
//SYSPRINT DD SYSOUT=*
//SYSUDUMP DD SYSOUT=*
//SYSTSIN DD *
DSN SYSTEM(DBxx)
RUN PROGRAM(DSNTIAUL) PLAN(DSNTIAUL) PARMS('SQL')
END
/*
//SYSIN DD *
SELECT statement
UNION
SELECT statement
;
/*
//*
