Обсуждение: concatenation of string literals

This works :
psql -c "select arcode ||  phnum from nccbor_member;"

 But this doesn't
psql -c " select arcode || '-' || phnum from nccbor_member;"

 It's an inconvience because I am doing mail merges in wordperfect
using postodbc, and I keep having to do things like put dashes in
phone numbers and such in wordperfect, is there another way to concat
string literals?

You will probably need to put parenthases around either the first two or
the last two strings:

psql -c " select (arcode || '-') || phnum from nccbor_member;"

that should work fine

My guess is you have to cast the '-' to text and that postgresql at the
moment sees '-' as a char:

select arcode || '-'::text || phnum from nccbor_members

Try:
psql -c " select (arcode || '-') || phnum from nccbor_member;"
