There seems to be inadequate info on filling arrays from a table, (vs
keyboarding), and
how to do a lookup in an array. I've tried to almost no avail.
- - - - - - -
I have a loop that I'm executing thousands of times and inside of it I have
SELECT INTO myvar column1 FROM mytable WHERE column2 =
somevalue ;
I'm trying to use an array lookup, ala this, that I found in the manual
ANY/SOME (array)
expression operator ANY (array expression)
But I'm a newbie to arrays, so I've tried
DECLARE myarray VARCHAR[] := array['''',''''] ;
then in the body
SELECT INTO myarray ARRAY[column1, column2] from mytable ;
I've discovered via trial and error that the above arrayification works
on a simple SQL query without variables.
How can I go about getting a simple variable out of that array on a
match on another column?
This query executing thousands of times is killing me!
Thanks,
Ralph
