_beginTransaction ( )

protected

Returns: void

_commit ( )

protected

Commit a transaction.

Returns: void

_connect ( )

protected

Creates a connection to the database.

Returns: void

Exceptions

Zend_Db_Adapter_Mysqli_Exception

_quote ( $value )

protected

Quote a raw string.

Parameters

mixed $value Raw string

Returns: string Quoted string

_rollBack ( )

protected

Roll-back a transaction.

Returns: void

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 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

Todo:: use INFORMATION_SCHEMA someday when MySQL's implementation isn't too slow.

Use mysqli extension API, because DESCRIBE doesn't work well as a prepared statement on MySQL 4.1.

See Also: Zend_Db_Adapter_Mysqli_Exception

The optional argument of a MySQL int type is not precision or length; it is only a hint for display width.

getQuoteIdentifierSymbol ( )

Returns the symbol the adapter uses for delimiting identifiers.

Returns: string

getServerVersion ( )

Retrieve server version in PHP style.

Returns: string

isConnected ( )

Test if a connection is active.

Returns: boolean

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.

MySQL does not support sequences, so $tableName and $primaryKey are ignored.

Parameters

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

Returns: string

Todo:: Return value should be int?

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

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

Parameters

string	$sql
int	$count
int	$offset	OPTIONAL

Returns: string

See Also: Zend_Db_Adapter_Mysqli_Exception; Zend_Db_Adapter_Mysqli_Exception

listTables ( )

Returns a list of the tables in the database.

Returns: array

See Also: Zend_Db_Adapter_Mysqli_Exception

prepare ( $sql )

Prepare a statement and return a PDOStatement-like object.

Parameters

string $sql SQL query

Returns: Zend_Db_Statement_Mysqli

setFetchMode ( $mode )

Set the fetch mode.

Parameters

int $mode

Returns: void

Exceptions

Zend_Db_Adapter_Mysqli_Exception

See Also: Zend_Db_Adapter_Mysqli_Exception; Zend_Db_Adapter_Mysqli_Exception

supportsParameters ( $type )

Check if the adapter supports real SQL parameters.

Parameters

string $type 'positional' or 'named'

Returns: bool
