Constructor & Destructor Documentation

__construct

(

array

$config = array()

)

Constructor.

$config is an array of key/value pairs containing configuration options. Note that the SQLite options are different than most of the other PDO adapters in that no username or password are needed. Also, an extra config key "sqlite2" specifies compatibility mode.

dbname => (string) The name of the database to user (required, use :memory: for memory-based database)

sqlite2 => (boolean) PDO_SQLITE defaults to SQLite 3. For compatibility with an older SQLite 2 database, set this to TRUE.

Parameters

array

$config

An array of configuration keys.

Member Function Documentation

_checkRequiredOptions ( array  $config )

protected

Check for config options that are mandatory.

Throw exceptions if any are missing.

Parameters

array

$config

Exceptions

Zend_Db_Adapter_Exception

See Also

Zend_Db_Adapter_Exception

_connect ( )

protected

Special configuration for SQLite behavior: make sure that result sets contain keys like 'column' instead of 'table.column'.

Exceptions

Zend_Db_Adapter_Exception

if we already have a PDO object, no need to re-connect.

_dsn ( )

protected

DSN builder.

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

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

SQLite INTEGER primary key is always auto-increment.

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

listTables

(

)

Returns a list of the tables in the database.

Returns

array
