Re: Bit string help, please - Mailing list pgsql-sql

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;
