Hi all;

I'm selecting from a table that has a varchar(1000) but I only want to
display the firs 20 characters. Looked at the string functions in the docs
but nothing jumped out...

Suggestions?

Thanks in advance

substring(string [from int] [for int])

Hi,
I think you can use the overlay function to do this.

http://www.postgresql.org/docs/current/static/functions-string.html

create table t1 (f char(10));
insert into t1 values ('abcdefg'),('hijklmno');
-- the below cmd will display only the first 2 characters of f.
-- if you want trim the spaces :) after this.
select overlay(f placing ' ' from 3 to 10);

Regards
kalyan

Hi all;

I'm selecting from a table that has a varchar(1000) but I only want to
display
the firs 20 characters. Looked at the string functions in the docs but
nothing
jumped out...

Suggestions?

Thanks in advance
