Subj:   Phone number matching from dec to char
From:   Burton, Bruce

I have two tables to match by phone number. Phone number in either case is in a standard 10 byte format with npa, nxx, line.

table 1 phone# decimal(10,0)
table 2 phone# char(10)

I've tried casting phone1 as char(10) and phone2 as dec(10,0) but no luck matching...comes up with a truncation error when casting phone1 as char(10) and comes up with 'bad data' when casting phone 2 as dec(10,0).

I finally got the match to work when I did a substring:

where substr(phone1,2,10))=phone2

Not sure why this worked. Any suggestions on the best way to cast either one of the variables?
