Declaring a Variable

Question

0.00/5 (No votes)

I would normally declare a variable in the following manner...

DECLARE @myVariable Text
SET @myVariable = 'pages'

SELECT
@myVariable
FROM
coredata

How would this change in PostgreSQL (...pgAdmin III) query?

Hi,

Have a look here:

There is no such feature in PostgreSQL. You can do it only in pl/PgSQL (or other pl/*), but not in plain SQL.

For a beginner (...in PostgreSQL) the http://stackoverflow.com/a/1491329[^] solution is a bit confusing.

Yes, but it answers your question.

Ok, I'll work on it...but PostgreSQL seems to have made something relatively simple - complex.
