Re: psql questions

Hi John,

Thanks, I had tried the semi-colon, it's the unusual quoting syntax I was
missing.

\set '/'jed\''
select :jed;

Is that the only way you can quote it to make a string work?

You prefix the variable with a colon to get the value. Here are a few
examples:

\set mystring '\'here is a string\''

select :mystring || ' test';
        ?column?
----------------------
  here is a string test
(1 row)


\set myint 37

select :myint + 10;
  ?column?
----------
        47
(1 row)
