Question

This is a summary of what I am trying to do:

$array[0] = 1;
$array[1] = 2;

$sql = "SELECT * FROM table WHERE some_id = $array"

Obviously, there are some syntax issues, but this is what I want to do, and I haven’t found anything yet that shows how to do it.

Currently, my plan is to do something along these lines:

foreach($idList as $is)
    $where .= 'some_id=' . $id . ' OR';
endforeach

$sql = "SELECT * FROM table WHERE " . $where;

So is there support in PostgreSQL to use an array to search, or do I have to do something similar to my solution?

Answer 1

SELECT  *
FROM    table
WHERE   some_id = ANY(ARRAY[1, 2])

or ANSI-compatible:

SELECT  *
FROM    table
WHERE   some_id IN (1, 2)

The ANY syntax is preferred because the array as a whole can be passed in a bound variable:

SELECT  *
FROM    table
WHERE   some_id = ANY(?::INT[])

You would need to pass a string representation of the array: {1,2}
