NAME

DBIx::QuickORM::Dialect::SQLite - SQLite dialect for DBIx::QuickORM.

DESCRIPTION

The SQLite-specific DBIx::QuickORM::Dialect. Introspects schema metadata from SQLite's pragma_* tables and sqlite_master, drives transactions and savepoints via the SQLite driver, and reports SQLite's feature set (RETURNING support, no async support).

SYNOPSIS

my $dialect = DBIx::QuickORM::Dialect::SQLite->new(dbh => $dbh, db_name => $name);

PUBLIC METHODS

$driver = $dialect->dbi_driver
$name = $dialect->dialect_name
$bool = $dialect->supports_returning_update
$bool = $dialect->supports_returning_insert
$bool = $dialect->supports_returning_delete
$bool = $dialect->async_supported
$bool = $dialect->async_cancel_supported

Feature flags and constants describing the SQLite dialect. SQLite does not support async queries.

$stype = $dialect->supports_type($type)

Returns SQLite's native storage type name for a supported logical type, or nothing. SQLite has no native JSON type; JSON-ish types fall back to TEXT via supports_type('text').

$dialect->async_prepare_args
$dialect->async_ready
$dialect->async_result
$dialect->async_cancel

SQLite does not support async queries; these croak.

$version = $dialect->db_version

The version of the SQLite library itself (not the DBD::SQLite module version).

$dialect->start_txn(%params)
$dialect->commit_txn(%params)
$dialect->rollback_txn(%params)
$dialect->create_savepoint(%params)
$dialect->commit_savepoint(%params)
$dialect->rollback_savepoint(%params)

Transaction and savepoint control via the SQLite driver. Each accepts an optional dbh parameter, defaulting to the dialect's own handle; savepoint methods take a savepoint name.

$dsn = $dialect->dsn($db)

Builds a SQLite DSN string from a database config object.

PUBLIC METHODS

$tables = $dialect->build_tables_from_db(%params)

Introspects all tables and views (including temp ones) and returns a hashref of name to schema-table object.

($pk, $unique, $links) = $dialect->build_table_keys_from_db($table, %params)

Introspects a table's primary key, unique keys, and foreign-key links.

$bool = $dialect->table_has_autoinc($table)

True if the named table declares an AUTOINCREMENT column.

$columns = $dialect->build_columns_from_db($table, %params)

Introspects a table's columns and returns a hashref of column name to column object.

$indexes = $dialect->build_indexes_from_db($table, %params)

Introspects a table's indexes and returns an arrayref of index specs.

PRIVATE METHODS

@cols = $dialect->_primary_key($table)

Returns the primary-key column names for a table, ordered by key position.

$ddl_or_undef = $dialect->_table_ddl($table)

The stored CREATE TABLE statement for the named table (permanent or temp), or undef when the table does not exist.

$sql = $dialect->_strip_sql_noise($sql)

Returns the SQL with string literals replaced by empty strings and comments removed, so keyword matching cannot false-positive on either.

$col_or_undef = $dialect->_rowid_alias_column($table)

The name of the column that aliases SQLite's rowid, or undef if the table has none. The alias rule: a rowid table (no WITHOUT ROWID) with a single-column primary key whose declared type is exactly INTEGER (INT, BIGINT, etc. do not alias). Not handled: the obscure x INTEGER PRIMARY KEY DESC column-definition form, which SQLite does not treat as an alias.
