Microsoft SQL Server Functions (PDO_SQLSRV)

Introduzione

PDO_SQLSRV is a driver that implements the PHP Data Objects (PDO) interface to enable access from PHP to MS SQL Server (starting with SQL Server 2005) and SQL Azure databases.

Installazione

The most recent version of the driver is available for download here: » SQLSRV download. The driver sources are hosted in a » public repository.

For more information about system requirements, see » SQLSRV System Requirements.

On Windows the PDO_SQLSRV extension is enabled by downloading and adding appropriate DLL files to the PHP extension directory and the corresponding entry to the php.ini file.

On Linux and macOS, the PDO_SQLSRV extension can be installed using » PECL. See the » installation tutorial for details.

Costanti predefinite

Le costanti qui sotto sono definite da questo driver, e sono disponibili solo quanto l'estensione è stata o compilata nel PHP o caricata dinamicamente a runtime. In aggiunta, queste costanti specifiche del driver dovrebbero essere usate solo se si sta usando il driver stesso. Utilizzare attributi specifici di mysql con il driver postgres può portare a risultati imprevedibili. PDO::getAttribute() può essere usata per ottenere l'attributo PDO_ATTR_DRIVER_NAME per identificare il driver, se il codice può funzionare con driver differenti.

PDO::SQLSRV_TXN_READ_UNCOMMITTED (int)
This constant is an acceptable value for the SQLSRV DSN key TransactionIsolation. This constant sets the transaction isolation level for the connection to Read Uncommitted.
PDO::SQLSRV_TXN_READ_COMMITTED (int)
This constant is an acceptable value for the SQLSRV DSN key TransactionIsolation. This constant sets the transaction isolation level for the connection to Read Committed.
PDO::SQLSRV_TXN_REPEATABLE_READ (int)
This constant is an acceptable value for the SQLSRV DSN key TransactionIsolation. This constant sets the transaction isolation level for the connection to Repeateable Read.
PDO::SQLSRV_TXN_SNAPSHOT (int)
This constant is an acceptable value for the SQLSRV DSN key TransactionIsolation. This constant sets the transaction isolation level for the connection to Snapshot.
PDO::SQLSRV_TXN_SERIALIZABLE (int)
This constant is an acceptable value for the SQLSRV DSN key TransactionIsolation. This constant sets the transaction isolation level for the connection to Serializable.
PDO::SQLSRV_ENCODING_BINARY (int)
Specifies that data is sent/retrieved as a raw byte stream to/from the server without performing encoding or translation. This constant can be passed to PDOStatement::setAttribute, PDO::prepare, PDOStatement::bindColumn, and PDOStatement::bindParam.
PDO::SQLSRV_ENCODING_SYSTEM (int)
Specifies that data is sent/retrieved to/from the server as 8-bit characters as specified in the code page of the Windows locale that is set on the system. Any multi-byte characters or characters that do not map into this code page are substituted with a single byte question mark (?) character. This constant can be passed to PDOStatement::setAttribute, PDO::setAttribute, PDO::prepare, PDOStatement::bindColumn, and PDOStatement::bindParam.
PDO::SQLSRV_ENCODING_UTF8 (int)
Specifies that data is sent/retrieved to/from the server in UTF-8 encoding. This is the default encoding. This constant can be passed to PDOStatement::setAttribute, PDO::setAttribute, PDO::prepare, PDOStatement::bindColumn, and PDOStatement::bindParam.
PDO::SQLSRV_ENCODING_DEFAULT (int)
Specifies that data is sent/retrieved to/from the server according to PDO::SQLSRV_ENCODING_SYSTEM if specified during connection. The connection's encoding is used if specified in a prepare statement. This constant can be passed to PDOStatement::setAttribute, PDO::setAttribute, PDO::prepare, PDOStatement::bindColumn, and PDOStatement::bindParam.
PDO::SQLSRV_ATTR_QUERY_TIMEOUT (int)
A non-negative integer representing the timeout period, in seconds. Zero (0) is the default and means no timeout. This constant can be passed to PDOStatement::setAttribute, PDO::setAttribute, and PDO::prepare.
PDO::SQLSRV_ATTR_DIRECT_QUERY (int)
Indicates that a query should be executed directly, without being prepared. This constant can be passed to PDO::setAttribute, and PDO::prepare. For more information, see » Direct and Prepared Statement Execution.

An updated driver compatible with both PHP 7.0 and Linux is available on the PHP-7.0-Linux branch of https://github.com/Microsoft/msphpsql/

This is more up to date and supports some additional features over the ODBC / DBLIB drivers.

It is currently considered an 'Early Technical Preview' and hence has some limitations, but in my experience it has been stable.

Watch out!

If you use PDO SQLSRV on windows 7, using 32 bit php on XAMMP, you might encounter driver problems : "This extension requires the Microsoft ODBC Driver 11 for SQL Server to communicate with SQL Server"

The reason, Microsoft 32-bit ODBC driver doesn't install properly on 64-bit Windows 7.

Check the solution to PDO SQLSRV driver problem here in StackOverflow
