Hi Ed,
I tried exactly what you did and it works for me.
My postgres is 8.3.0 running on redhat advanced
server. This is what it told me:
prompt=# SELECT ('1' || repeat('0', 7))::bit varying;
varbit
----------
10000000
(1 row)
prompt=#

Tena Sakai

Subject: Re: [SQL] Bit string help, please
I tried this real quick at the psql command prompt, and unfortunately it
doesn't work:
mydb=# select ('1' || repeat('0',7))::bit varying;
ERROR: cannot cast type text to bit varying
I appreciate the try though. Any other ideas? I am using PostgreSQL
8.2.3.1. I don't know if that matters too much.
Thanks,
Ed

Try casting from a string:
SELECT ('1' || repeat('0', n-1))::bit varying;
