Postgresql Select rows where column = array

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

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}
