Detailed Description

Definition at line 39 of file Sqlite.php.


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$configAn 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

Zend_Db_Adapter_Exception

Reimplemented from Zend_Db_Adapter_Abstract.

Definition at line 104 of file Sqlite.php.

_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$tableName
string$schemaNameOPTIONAL
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$offsetOPTIONAL
Returns:
string
