Member Function Documentation

_beginTransaction ( )

protected

Begin a transaction.

It is necessary to override the abstract PDO transaction functions here, as the PDO driver for MSSQL does not support transactions.

_commit ( )

protected

Commit a transaction.

It is necessary to override the abstract PDO transaction functions here, as the PDO driver for MSSQL does not support transactions.

_connect ( )

protected

Returns

void

_dsn ( )

protected

Creates a PDO DSN for the adapter from $this->_config settings.

Returns

string

_rollBack ( )

protected

Roll-back a transaction.

It is necessary to override the abstract PDO transaction functions here, as the PDO driver for MSSQL does not support transactions.

describeTable	(		$tableName,
			$schemaName = null
	)

Returns the column descriptions for a table.

The return value is an associative array keyed by the column name, as returned by the RDBMS.

The value of each array element is an associative array with the following keys:

SCHEMA_NAME => string; name of database or schema TABLE_NAME => string; COLUMN_NAME => string; column name COLUMN_POSITION => number; ordinal position of column in table DATA_TYPE => string; SQL datatype name of column DEFAULT => string; default expression of column, null if none NULLABLE => boolean; true if column can have nulls LENGTH => number; length of CHAR/VARCHAR SCALE => number; scale of NUMERIC/DECIMAL PRECISION => number; precision of NUMERIC/DECIMAL UNSIGNED => boolean; unsigned property of an integer type PRIMARY => boolean; true if column is part of the primary key PRIMARY_POSITION => integer; position of column in primary key PRIMARY_AUTO => integer; position of auto-generated column in primary key

Todo:

Discover column primary key position.

Discover integer unsigned property.

Parameters

string	$tableName
string	$schemaName	OPTIONAL

Returns

array

Discover metadata information about this table.

Discover primary key column(s) for this table.

getServerVersion

(

)

Retrieve server version in PHP style Pdo_Mssql doesn't support getAttribute(PDO::ATTR_SERVER_VERSION)

Returns

string

lastInsertId	(		$tableName = null,
			$primaryKey = null
	)

Gets the last ID generated automatically by an IDENTITY/AUTOINCREMENT column.

As a convention, on RDBMS brands that support sequences (e.g. Oracle, PostgreSQL, DB2), this method forms the name of a sequence from the arguments and returns the last id generated by that sequence. On RDBMS brands that support IDENTITY/AUTOINCREMENT columns, this method returns the last value generated for such a column, and the table name argument is disregarded.

Microsoft SQL Server does not support sequences, so the arguments to this method are ignored.

Parameters

string	$tableName	OPTIONAL Name of table.
string	$primaryKey	OPTIONAL Name of primary key column.

Returns

string

Exceptions

Zend_Db_Adapter_Exception

limit	(		$sql,
			$count,
			$offset = 0
	)

Adds an adapter-specific LIMIT clause to the SELECT statement.

string $sql integer $count integer $offset OPTIONAL Zend_Db_Adapter_Exception string
