Member Function Documentation

_dsn()

_dsn ( )

protected

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

Returns

string

Definition at line 81 of file Oci.php.

    {
        // baseline of DSN parts
        $dsn = $this->_config;

        if (isset($dsn['host'])) {

            $tns .= ';charset=' . $dsn['charset'];
        }

        return $this->_pdoType . ':' . $tns;
    }

_quote()

_quote (   $value )

protected

Quote a raw string. Most PDO drivers have an implementation for the quote() method, but the Oracle OCI driver must use the same implementation as the Zend_Db_Adapter_Abstract class.

Parameters

string

$value

Raw string

Returns

string Quoted string

Definition at line 117 of file Oci.php.

    {
        if (is_int($value) || is_float($value)) {
            return $value;
        }
        $value = str_replace("'", "''", $value);
        return "'" . addcslashes($value, "\000\n\r\\\032") . "'";
    }

describeTable()

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 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 IDENTITY => integer; true if column is auto-generated with unique values

Todo:

Discover integer unsigned property.

Parameters

string	$tableName
string	$schemaName	OPTIONAL

Returns

array

Use FETCH_NUM so we are not dependent on the CASE attribute of the PDO connection

Oracle does not support auto-increment keys.

lastInsertId()

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.

Oracle does not support IDENTITY columns, so if the sequence is not specified, this method returns null.

Parameters

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

Returns

string

lastSequenceId()

lastSequenceId

(

$sequenceName

)

Return the most recent value from the specified sequence in the database. This is supported only on RDBMS brands that support sequences (e.g. Oracle, PostgreSQL, DB2). Other RDBMS brands return null.

        return $value;
    }

limit()

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

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

Parameters

string	$sql
integer	$count
integer	$offset

Exceptions

Zend_Db_Adapter_Exception

Returns

string

Zend_Db_Adapter_Exception

Oracle does not implement the LIMIT clause as some RDBMS do. We have to simulate it with subqueries and ROWNUM. Unfortunately because we use the column wildcard "*", this puts an extra column into the query result set.

Parameters

Returns

integer

quoteTableAs()

quoteTableAs	(		$ident,
			$alias = null,
			$auto = false
	)

Quote a table identifier and alias.

Parameters

string | array | Zend_Db_Expr	$ident	The identifier or expression.
string	$alias	An alias for the table.

Returns

string The quoted identifier and alias.
