postgres - comparing two arrays

Question

postgres has an array data type, in this case a numeric array:

CREATE TABLE sal_emp (name text, pay_by_quarter integer[]);
INSERT INTO sal_emp VALUES (\'one\         


        

Answer 1

figured it ... there's an && operator

http://www.postgresql.org/docs/8.2/static/functions-array.html

"&& overlap (have elements in common) ARRAY[1,4,3] && ARRAY[2,1]"

Answer 2

Trying not to plagiarise pstanton's answer, but clarifying a use case.

To have a condition that is satisfied by any of two (or more) columns having any of a list of values:

 select * from mytable
 where array(col1, col2) && array('foo', 'bar', baz')
