_beginTransaction ( )

protected

Begin a transaction.

Returns: void

_commit ( )

protected

Commit a transaction.

Returns: void

See Also: Zend_Db_Adapter_Db2_Exception

_connect ( )

protected

Creates a connection resource.

Returns: void

See Also: Zend_Db_Adapter_Db2_Exception; Zend_Db_Adapter_Db2_Exception

_determineI5 ( )

protected

Check the connection parameters according to verify type of used OS.

Returns: void

_getExecuteMode ( )

Gets the execution mode.

Returns: int the execution mode (DB2_AUTOCOMMIT_ON or DB2_AUTOCOMMIT_OFF)

_i5LastInsertId	(	$objectName = `null`,
		$idType = `null`
	)

protected

_i5listTables ( $schema = null )

protected

Db2 On I5 specific method.

Returns a list of the tables in the database . Used only for DB2/400.

Returns: array

_quote ( $value )

protected

Quote a raw string.

Parameters

string $value Raw string

Returns: string Quoted string

Use db2_escape_string() if it is present in the IBM DB2 extension. But some supported versions of PHP do not include this function, so fall back to default quoting in the parent class.

_rollBack ( )

protected

Rollback a transaction.

Returns: void

See Also: Zend_Db_Adapter_Db2_Exception

_setExecuteMode ( $mode )

Parameters

integer $mode

Returns: void

See Also: Zend_Db_Adapter_Db2_Exception

closeConnection ( )

Force the connection to close.

Returns: void

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 DB2 not supports UNSIGNED integer. 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

Parameters

string	$tableName
string	$schemaName	OPTIONAL

Returns: array

To avoid case issues, fetch using FETCH_NUM

The ordering of columns is defined by the query so we can map to variables to improve readability

In IBM DB2, an column can be IDENTITY even if it is not part of the PRIMARY KEY.

getQuoteIdentifierSymbol ( )

Returns: string

getServerVersion ( )

Retrieve server version in PHP style.

Returns: string

isConnected ( )

Test if a connection is active.

Returns: boolean

isI5 ( )

Return whether or not this is running on i5.

Returns: bool

lastInsertId	(	$tableName = `null`,
		$primaryKey = `null`,
		$idType = `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.

The IDENTITY_VAL_LOCAL() function gives the last generated identity value in the current process, even if it was for a GENERATED column.

Parameters

string	$tableName	OPTIONAL
string	$primaryKey	OPTIONAL
string	$idType	OPTIONAL used for i5 platform to define sequence/idenity unique value

Returns: string

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.

Parameters

string $sequenceName

Returns: string

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

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

Parameters

string	$sql
integer	$count
integer	$offset	OPTIONAL

Returns: string

See Also: Zend_Db_Adapter_Db2_Exception; Zend_Db_Adapter_Db2_Exception

DB2 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.

listTables ( $schema = null )

Returns a list of the tables in the database.

Parameters

string $schema OPTIONAL

Returns: array

nextSequenceId ( $sequenceName )

Generate a new value from the specified sequence in the database, and return it.

This is supported only on RDBMS brands that support sequences (e.g. Oracle, PostgreSQL, DB2). Other RDBMS brands return null.

Parameters

string $sequenceName

Returns: string

prepare ( $sql )

Returns an SQL statement for preparation.

Parameters

string $sql The SQL statement with placeholders.

Returns: Zend_Db_Statement_Db2

setFetchMode ( $mode )

Set the fetch mode.

Parameters

integer $mode

Returns: void

Exceptions

Zend_Db_Adapter_Db2_Exception

See Also: Zend_Db_Adapter_Db2_Exception; Zend_Db_Adapter_Db2_Exception

supportsParameters ( $type )

Check if the adapter supports real SQL parameters.

Parameters

string $type 'positional' or 'named'

Returns: bool
