This command do it

Code:
eval echo -ne "db2' '-x' \"'select' 'DOCID' 'from' 'ICMADMIN.{$(paste -sd, et.tst)}' where ITEMID='\'{$(paste -sd, itid.tst)}\''\"\n'"
db2 -x "select DOCID from ICMADMIN.NNSPDM_PRI_01001 where ITEMID='A1001001A19D02A60150B20570'"
 db2 -x "select DOCID from ICMADMIN.NNSPDM_PRI_01001 where ITEMID='A1001001A19D02A60150B20572'"
 db2 -x "select DOCID from ICMADMIN.NNSPDM_PRI_01001 where ITEMID='A1001001A19D02A60150B20574'"
 db2 -x "select DOCID from ICMADMIN.NNSPDM_PRI_01001 where ITEMID='A1001001A19D02A60150E20578'"
 db2 -x "select DOCID from ICMADMIN.NNSPDM_PRI_01001 where ITEMID='A1001001A19D02A60150E20576'"
 db2 -x "select DOCID from ICMADMIN.NNSTDM_DOC_04001 where ITEMID='A1001001A19D02A60150B20570'"

but if I try do
Code:
bash <(eval echo -ne "db2' '-x' \"'select' 'DOCID' 'from' 'ICMADMIN.{$(paste -sd, et.tst)}' where ITEMID='\'{$(paste -sd, itid.tst)}\''\"\n'")

but the db2 connection is almost exists.

If I take a command with cut/paste i got no errors.

Well, I can absolutely accurately reproduce
Code:
eval echo -ne "db2' '-x' \"'select' 'DOCID' 'from' 'ICMADMIN.{$(paste -sd, et.tst)}' where ITEMID='\'{$(paste -sd, itid.tst)}\''\"\n'"
db2 -x "select DOCID from ICMADMIN.NZGPIM_DAT_01001 where ITEMID='A1001001A19D02A60150E20576'"

Now hopefully right

The echo is correct, now should I make it executable.
The other variant works too:

Code:
join -12 -22 -o 1.1,2.1 <(xargs -n1 <et.tst) <(xargs -n1 <itid.tst) | 
while read a b; do
	eval echo -ne "db2' '-x' \"'select' 'DOCID' 'from' 'ICMADMIN."$a"' where ITEMID='\'"$b"\''\"\n'"
done

Code:
join -12 -22 -o 1.1,2.1 et.tst itid.tst |
while read a b; do
    db2 -x "select DOCID from ICMADMIN.$a where ITEMID='$b'"
done

Reread I fixed the code

I made the script with
Code:
#!/bin/bash -x

Code:
+ join -12 -22 -o 1.1,2.1 et.tst itid.tst
+ read a b
+ db2 -x 'select DOCID from ICMADMIN.NNSPDM_PRI_01001 where ITEMID='\''A1001001A19D02A60150B20570'\'''

My advice. Just make sure that one line is executed without any cycles.
Then the working sample will be conveniently substitute in script
Code:
db2 -x "select DOCID from ICMADMIN.NNSPDM_PRI_01001 where ITEMID='A1001001A19D02A60150B20570'"

I have nothing to check, I have not installed db2

The overall approach seems a bit complex, selecting rows with identical criteria from a few different tables. How about serving a single db2 invocation a script, selecting all the criteria with an IN clause from a table, and running this across the tables needed? Letting the shell do (almost) all the transformations, although that needs some shell variable crisscross. Like


Code:
ARGLIST=$(sed -n ":L; N; \${s/\n/','/g; s/^\|$/'/g; p; q};  bL; " file2)

TABLES=( $(<file1) )
IFS=$'\n'
TABLES=( ${TABLES[*]/#/select DOCID from ICMADMIN.} )
db2  <<< "${TABLES[*]/%/ where ITEMID in ($ARGLIST);}"
select DOCID from ICMADMIN.NNDTY4_DOC_05001 where ITEMID in ('A1001001A19D02A60148J20560','A1001001A19D02A60149F20562','A1001001A19D02A60149F20566','A1001001A19D02A60149F20564','A1001001A19D02A60149F20568','A1001001A19D02A60150B20570','A1001001A19D02A60150B20572','A1001001A19D02A60150B20574','A1001001A19D02A60150E20578','A1001001A19D02A60150E20576');
select DOCID from ICMADMIN.NNDTY5_DOC_05001 where ITEMID in ('A1001001A19D02A60148J20560','A1001001A19D02A60149F20562','A1001001A19D02A60149F20566','A1001001A19D02A60149F20564','A1001001A19D02A60149F20568','A1001001A19D02A60150B20570','A1001001A19D02A60150B20572','A1001001A19D02A60150B20574','A1001001A19D02A60150E20578','A1001001A19D02A60150E20576');
