Description:
------------
Executing a prepared statement that includes identical named
placeholders among others breaks postgresql's PREPARE command.
PDO->prepare does not translate the number of unique placeholders in
the statement correctly. Looks like it increments the argument number on
the basis of the placeholder's position index instead using an unique
index (see therefor pgsql log entries in the actual result section).
pdo_pgsql
My postgresql version is 8.2.5
Reproduce code:
---------------
Table Setup
CREATE TABLE nodes
(
id integer NOT NULL PRIMARY KEY
, root integer NOT NULL
, lft integer NOT NULL
, rgt integer NOT NULL
);
INSERT INTO nodes (id, root, lft, rgt) VALUES (1, 1, 1, 6);
INSERT INTO nodes (id, root, lft, rgt) VALUES (2, 1, 2, 3);
INSERT INTO nodes (id, root, lft, rgt) VALUES (3, 1, 4, 5);
// Assumes that $Dbh is pdo object
// Let pgsql log all statements, so we can see the prepared statement
as it is seen by the postgresql server
$Dbh->query("SET log_statement = 'all'");
$Stmt = $Dbh->prepare('SELECT * FROM nodes WHERE (lft > :left OR rgt >
:left) AND root = :rootId');
$Stmt->bindValue('left', 1, PDO::PARAM_INT);
$Stmt->bindValue('rootId', 1, PDO::PARAM_INT);
if (!$Stmt->execute())
print_r($Stmt->errorInfo());
// And a second one to get it clearly
$Stmt = $Dbh->prepare('SELECT * FROM nodes WHERE (lft > :left OR rgt >
:left OR rgt > :left) AND root = :rootId');
$Stmt->bindValue('left', 1, PDO::PARAM_INT);
$Stmt->bindValue('rootId', 1, PDO::PARAM_INT);
if (!$Stmt->execute())
print_r($Stmt->errorInfo());
Expected result:
----------------
no error
In the pgsql log:
STATEMENT: SELECT * FROM nodes WHERE (lft > $1 OR rgt > $1) AND root =
$2
STATEMENT: SELECT * FROM nodes WHERE (lft > $1 OR rgt > $1 OR rgt > $1)
AND root = $2
Actual result:
--------------
Array
(
[0] => 42P18
[1] => 7
[2] => ERROR: could not determine data type of parameter $2
)
Array
(
[0] => 42P18
[1] => 7
[2] => ERROR: could not determine data type of parameter $2
)
And in the pgsql log:
STATEMENT: SELECT * FROM nodes WHERE (lft > $1 OR rgt > $1) AND root =
$3
STATEMENT: SELECT * FROM nodes WHERE (lft > $1 OR rgt > $1 OR rgt > $1)
AND root = $4
