Description

Class for connecting to SQLite2 and SQLite3 databases and performing common operations.

Properties

$_numericDataTypes
jump to class

array $_numericDataTypes = 'array'

Keys are UPPERCASE SQL datatypes or the constants Zend_Db::INT_TYPE, Zend_Db::BIGINT_TYPE, or Zend_Db::FLOAT_TYPE.

Values are: 0 = 32-bit integer 1 = 64-bit integer 2 = float or decimal

Details

$_numericDataTypes: array
Associative array of datatypes to values 0, 1, or 2.
visibility: protected

final: false
static: false

$_pdoType
jump to class

string $_pdoType = 'sqlite'

PDO type

Details

$_pdoType: string
visibility: protected

Methods

__construct

__construct(
          array $config
              =

          )
        
        :

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.

Arguments

$config: array
An array of configuration keys.
