ADD COMMAND-link 2 fields where numeric value matches

Question

I have a Add Command that looks like this.
SELECT *
FROM "AS400"."MTMODBC"."#MTMTRP" "_MTMTRP"
LEFT OUTER JOIN (
SELECT CHGTRP, CHGFCD, Max(CHGDTE) As Max_CHGDTE, Max(CHGTIM) As Max_CHGTIM
FROM  "AS400"."MTMODBC"."#MTMTCHG" "_MTMTCHG"
WHERE CHGFCD= '076'
GROUP BY CHGTRP, CHGFCD
) C1
ON
TRIP#=CHGTRP
LEFT OUTER JOIN "AS400"."MTMODBC"."#MTMGAS" "_MTMGAS" ON (TRIP#=GTRIP#)
LEFT OUTER JOIN "AS400"."MTMODBC"."#MTMMBR" "_MTMMBR" ON (TCSTKY=MCSTKY)
LEFT OUTER JOIN "AS400"."MTMODBC"."#DMSFAC" "_DMSFAC" ON (TDELZP=DFZIP and DFADDR1=TDELVA)
LEFT OUTER JOIN (SELECT TRIP# AS NTRIP#, THCPCS
FROM "AS400"."MTMODBC"."#MTMND" "_MTMND") N1
ON TRIP#=NTRIP#
WHERE TINSCD= '0342' and
(TRPFLG Like 'S%' OR
TRPFLG in ('X1','X2','X3')) and
TREASC not in ('53','81') and
TAPTDT>=20101001 and
TAPTDT<=20110331
The bolded fields are Alpha numeric and I would like to match them on values
EX: DFADDR1 has a value 123 High St
and TDELVA has a value 123 High St
How do I match them on the first 3 digits?
Thanks!

Hi,
What about using  substing function in the join.
(TDELZP=DFZIP and substr(DFADDR1,0,3)=substr(TDELVA,0,3))
I have assumed that numeric filed length is fixed.Which is the database?
