PDO: Got error when exec 'DELETE' on something doesn't exist #336
Description
Hi,
I got a weird behavior when I try to delete something that doesn't exist (table exist, but the row I want to deleted doesn't), with pdo driver.
On PHP 5.6, there were no problem.
Bellow a test script and results obtained on this system:

Summary Microsoft Drivers for PHP for SQL Server
(SQLSRV)
Description The Microsoft Drivers for PHP for SQL Server are
PHP extensions that allow for the reading and
writing of SQL Server data from within PHP
scripts. The SQLSRV extension provides a
procedural interface while the PDO_SQLSRV
extension implements PDO for accessing data in
all editions of SQL Server 2005 and later
(including Azure SQL DB). These drivers rely on
the Microsoft ODBC Driver for SQL Server to
handle the low-level communication with SQL
Server.
*This package contains only the SQLSRV driver.*
