Bug #62998 [NEW]: pg_query_params() doesn't handle NULL
From: php at richardneill dot org
Operating system: Linux
PHP version: 5.3.16
Package: PostgreSQL related
Bug Type: Bug
Bug description:pg_query_params() doesn't handle NULL
Description:
------------
pg_query_params($conn,$sql,$params) is supposed to correctly handle
NULL->SQL_NULL. It doesn't do this (despite the documentation); instead it
breaks the query.
Documentation
"If parameters are used, they are referred to in the query string as $1,
$2, etc. params specifies the actual values of the parameters. A NULL value
in this array means the corresponding parameter is SQL NULL. "
Test script:
---------------
Here's a simple example:
$result = pg_query_params ($conn,
"select CASE WHEN NULL is $1 then 'it is null' ELSE 'it is not null'
END",
array(NULL) );
echo pg_last_error($conn);
print_r (pg_fetch_assoc($result));
This query fails, because the parameter $1 is not actually passed as NULL,
instead it seems to be the empty string.
My SQL is definitely right:
pg_query_params ($conn,
"select CASE WHEN NULL is NULL then 'it is null' ELSE 'it is not null'
END",
array() );
works fine, to return the string "it is null".
Expected result:
----------------
It should be possible to pass SQL_NULL to the database in a parameter.
