Abstract

Extends: ORM\Dbal\Dbal

Database abstraction for SQLite databases

Methods

ORM\Dbal\Sqlite::__construct

public function __construct(
    \ORM\EntityManager $entityManager, 
    array $options = [], 
)

Dbal constructor.

Parameters

ORM\Dbal\Sqlite::__construct

↑ top

ORM\Dbal\Sqlite::beginTransaction

public function beginTransaction(): bool

Begin a transaction or create a savepoint

ORM\Dbal\Sqlite::beginTransaction

↑ top

ORM\Dbal\Sqlite::commit

public function commit(bool $all = false): bool

Commit the current transaction or decrease the savepoint counter

Actually nothing will be committed if there are savepoints. Instead the counter will be decreased and the commited savepoint will still be rolled back when you call rollback afterwards.

Hopefully that gives a hint why save points are no transactions and what the limitations are.

Begin transaction
  updates / inserts for transaction1
  Create savepoint transaction1
    updates / inserts for transaction2
    Create savepoint transaction2
      updates / inserts for transaction3
    <no commit here but you called commit for transaction3>
    updates / inserts for transaction2
  rollback of transaction2 to savepoint of transaction1
  update / inserts for transaction1
commit of transaction1

Parameters

ORM\Dbal\Sqlite::commit

↑ top

ORM\Dbal\Sqlite::delete

public function delete(string $table, array $where): int

Delete rows from $table using $where conditions

Where conditions can be an array of key => value pairs to check for equality or an array of expressions.

Examples: $dbal->delete('someTable', ['id' => 23]) $dbal->delete('user', ['name = \'john\'', 'OR email=\'john.doe@example.com\''])

Tip: Use the query builder to construct where conditions: $em->query('user')->where('name', 'john')->orWhere('email', '...')->delete();

Parameters

ORM\Dbal\Sqlite::delete

↑ top

ORM\Dbal\Sqlite::deleteEntity

public function deleteEntity(\ORM\Entity $entity): bool

Delete $entity from database

This method does not delete from the map - you can still receive the entity via fetch.

Parameters

ORM\Dbal\Sqlite::deleteEntity

↑ top

ORM\Dbal\Sqlite::describe

public function describe(string $table): \ORM\Dbal\Table|\ORM\Dbal\Column[]

Describe a table

Parameters

ORM\Dbal\Sqlite::describe

↑ top

ORM\Dbal\Sqlite::escapeIdentifier

public function escapeIdentifier(string $identifier): string

Returns $identifier quoted for use in a sql statement

Parameters

ORM\Dbal\Sqlite::escapeIdentifier

↑ top

ORM\Dbal\Sqlite::escapeValue

public function escapeValue(mixed $value): string

Returns $value formatted to use in a sql statement.

Parameters

ORM\Dbal\Sqlite::escapeValue

↑ top

ORM\Dbal\Sqlite::insert

public function insert(mixed $table, array $rows): mixed

Parameters

ORM\Dbal\Sqlite::insert

↑ top

ORM\Dbal\Sqlite::insertAndSync

public function insertAndSync(\ORM\Entity $entities): bool

Insert $entities and update with default values from database

The entities have to be from same type otherwise a InvalidArgument will be thrown.

Parameters

ORM\Dbal\Sqlite::insertAndSync

↑ top

ORM\Dbal\Sqlite::insertAndSyncWithAutoInc

public function insertAndSyncWithAutoInc(\ORM\Entity $entities): int|bool

Insert $entities and sync with auto increment primary key

The entities have to be from same type otherwise a InvalidArgument will be thrown.

Parameters

ORM\Dbal\Sqlite::insertAndSyncWithAutoInc

↑ top

ORM\Dbal\Sqlite::insertEntities

public function insertEntities(\ORM\Entity $entities): bool

Insert $entities into database

The entities have to be from same type otherwise a InvalidArgument will be thrown.

Parameters

ORM\Dbal\Sqlite::insertEntities

↑ top

ORM\Dbal\Sqlite::rollback

public function rollback(): bool

Rollback the current transaction or save point

ORM\Dbal\Sqlite::rollback

↑ top

ORM\Dbal\Sqlite::setOption

public function setOption(string $option, mixed $value): $this

Set $option to $value

Parameters

ORM\Dbal\Sqlite::setOption

↑ top

ORM\Dbal\Sqlite::update

public function update(
    string $table, 
    array $where, 
    array $updates, 
    array $joins = [], 
): int

Update $table using $where to set $updates

Simple usage: update('table', ['id' => 23], ['name' => 'John Doe'])

For advanced queries with parenthesis, joins (if supported from your DBMS) etc. use QueryBuilder:

$em->query('table')
 ->where('birth_date', '>', EM::raw('DATE_SUB(NOW(), INTERVAL 18 YEARS)'))
 ->update(['teenager' => true]);

Parameters

ORM\Dbal\Sqlite::update
