Summary: PDOStatement::execute() errors when querying for
backslash and question mark
Status: Bogus
Type: Bug
Package: PDO related
Operating System: Windows 7
PHP Version: 5.2.14
Block user comment: N
New Comment:
The problem is also specific to the order in which the parameters appear
in the
statement, for instance this also executes without problem:
$stmt = $pdo->prepare("SELECT * FROM table WHERE column1 = '?' AND
column2 =
'\'");
$result = $stmt->execute();
So I assume the issue lies in the way PDO parses the SQL statement when
preparing.

The question mark is surrounded by quotes and so should be used as a
literal value
to query the table column, not as a parameter placeholder. The exact
same SQL
statement executes fine when using PDO::query, e.g.
$result = $pdo->query("SELECT * FROM table WHERE column1 = '\' AND
column2 =
'?'");

Sorry, but your problem does not imply a bug in PHP itself. For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions. Due to the volume
of reports we can not explain in detail here why your report is not
a bug. The support channels will be able to provide an explanation
for you.
Thank you for your interest in PHP.
Question marks are parameter placeholders.

Description:
------------
Using PDO to prepare and then execute a statement that queries for a
backslash and
then a question mark sequentially in two columns generates a warning.
Test script:
---------------
$pdo = new PDO("mssql:dbname=mydb;host=myhost", "myuser",
"mypassword");
$stmt = $pdo->prepare("SELECT * FROM table WHERE column1 = '\' AND
column2 = '?'");
$result = $stmt->execute();
Expected result:
----------------
Array or false.
Actual result:
--------------
Warning: PDOStatement::execute() [pdostatement.execute]:
SQLSTATE[HY093]: Invalid
parameter number: no parameters were bound in ...
