Subject: [GENERAL] string = any()

Hi all.

I am writing PHP where it prepares a statement like:
$sql = 'select * from aTable where id = any($1)';

then in php I create a string:
$args = "{1,2,3}";

And run it:

$q = pg_query_params($db, $sql, $args);

This is not actual code, just a sample. And it works great for integers. I
cannot get it to work with strings.

Just running this in psql does not work either:
select 'bob' = any( '{''joe'', ''bob'' }' )

But this does:
select 'bob' = any( array['joe', 'bob'] )

But I can't seem to prepare and execute:
$sql = "select 'bob' = any( $1 )";
$args = "array['joe', 'bob']";
$q = pg_query_params($db, $sql, $args);

Running on 9.0.4 on Slackware 64.

Any hits would be appreciated.

Explicit casting is required otherwise the system simply treats you input as
a simple scalar varchar.

" SELECT 'bob' = ANY( $1::varchar[] ) ... "

You can also pass in a delimited string and perform a "split_to_array($1,
',')" - didn't check exact syntax but you get the idea
