ModularAccessor class
A database accessor implicitly created by a .drift
file.
When modular code generation is enabled, drift will emit a file with a ModularAccessor for each drift file instead of generating all the code for a database into a single file.

Methods
-
$expandVar(
int start, int amount) → String -
Used by generated code to expand array variables.
inherited
-
$write(
Component component, {bool? hasMultipleTables, int? startIndex}) → GenerationContext -
Will be used by generated code to resolve inline Dart components in sql by
writing the
component
.inherited -
$writeInsertable(
TableInfo< Table, dynamic> table, Insertable insertable, {int? startIndex}) → GenerationContext -
Writes column names and
VALUES
for an insert statement.inherited -
accessor<
T extends DatabaseAccessor< (GeneratedDatabase> >T create(GeneratedDatabase)) → T -
Find an accessor type, or create it with
create
. The result will be cached. -
alias<
T, D> (ResultSetImplementation< T, D> table, String alias) → T -
Creates a copy of the table with an alias so that it can be used in the
same query more than once.
inherited
-
batch(
FutureOr< void> runInBatch(Batch batch)) → Future<void> -
Runs statements inside a batch.
inherited
-
close(
) → Future< void> -
Closes this database and releases associated resources.
inherited
-
computeWithDatabase<
Ret> ({required FutureOr< Ret> computation(DB), required DB connect(DatabaseConnection)}) → Future<Ret> -
Available on DB, provided by the ComputeWithDriftIsolate extension
Spawns a short-lived isolate to run thecomputation
with a drift database. -
createStream<
T extends Object> (QueryStreamFetcher< T> stmt) → Stream<T> -
Creates and auto-updating stream from the given select statement. This
method should not be used directly.
inherited
-
customInsert(
String query, {List< Variable< variables = const [], Set<Object> >ResultSetImplementation> ? updates}) → Future<int> -
Executes a custom insert statement and returns the last inserted rowid.
inherited
-
customSelect(
String query, {List< Variable< variables = const [], Set<Object> >ResultSetImplementation> readsFrom = const {}}) → Selectable<QueryRow> -
Creates a custom select statement from the given sql
query
.inherited -
customSelectQuery(
String query, {List< Variable< variables = const [], Set<Object> >ResultSetImplementation> readsFrom = const {}}) → Selectable<QueryRow> -
Creates a custom select statement from the given sql
query
. To run the query once, use Selectable.get. For an auto-updating streams, set the set of tables the readyreadsFrom
and use Selectable.watch. If you know the query will never emit more than one row, you can also usegetSingle
andwatchSingle
which return the item directly without wrapping it into a list.inherited -
customStatement(
String statement, [List? args]) → Future< void> -
Executes the custom sql
statement
on the database.inherited -
customUpdate(
String query, {List< Variable< variables = const [], Set<Object> >ResultSetImplementation> ? updates, UpdateKind? updateKind}) → Future<int> -
Executes a custom delete or update statement and returns the amount of
rows that have been changed.
You can use the
updates
parameter so that drift knows which tables are affected by your query. All select streams that depend on a table specified there will then update their data. For more accurate results, you can also set theupdateKind
parameter to UpdateKind.delete or UpdateKind.update. This is optional, but can improve the accuracy of query updates, especially when using triggers.inherited -
customWriteReturning(
String query, {List< Variable< variables = const [], Set<Object> >ResultSetImplementation> ? updates, UpdateKind? updateKind}) → Future<List< QueryRow> > -
Runs a
INSERT
,UPDATE
orDELETE
statement returning rows.inherited -
delete<
T extends Table, D> (TableInfo< T, D> table) → DeleteStatement<T, D> -
Starts a DeleteStatement that can be used to delete rows from a table.
inherited
-
doWhenOpened<
T> (FutureOr< T> fn(QueryExecutor e)) → Future<T> -
Performs the async
fn
after this executor is ready, or directly if it's already ready.inherited -
exclusively<
T> (Future< T> action()) → Future<T> -
Obtains an exclusive lock on the current database context, runs
action
in it and then releases the lock.inherited -
into<
T extends Table, D> (TableInfo< T, D> table) → InsertStatement<T, D> -
Starts an InsertStatement for a given table. You can use that statement
to write data into the
table
by using InsertStatement.insert.inherited -
markTablesUpdated(
Iterable< TableInfo< tables) → voidTable, dynamic> > -
Marks the
tables
as updated.inherited -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyUpdates(
Set< TableUpdate> updates) → void -
Dispatches the set of
updates
to the stream query manager.inherited -
resultSet<
T extends ResultSetImplementation> (String name) → T -
Find a result set by its
name
in the database. The result is cached. -
select<
T extends HasResultSet, R> (ResultSetImplementation< T, R> table, {bool distinct = false}) → SimpleSelectStatement<T, R> -
Starts a query on the given table.
inherited
-
selectExpressions(
Iterable< Expression< columns) → Selectable<Object> >TypedResult> -
Creates a select statement without a
FROM
clause selectingcolumns
.inherited -
selectOnly<
T extends HasResultSet, R> (ResultSetImplementation< T, R> table, {bool distinct = false}) → JoinedSelectStatement<T, R> -
Starts a complex statement on
table
that doesn't necessarily use all oftable
's columns.inherited -
serializableConnection(
) → Future< DriftIsolate> -
Available on DB, provided by the ComputeWithDriftIsolate extension
Creates a DriftIsolate that, when connected to, will run queries on the database already opened bythis
. -
tableUpdates(
[TableUpdateQuery query = const TableUpdateQuery.any()]) → Stream< Set< TableUpdate> > -
Listen for table updates reported through notifyUpdates.
inherited
-
toString(
) → String -
A string representation of this object.
inherited
-
transaction<
T> (Future< T> action(), {bool requireNew = false}) → Future<T> -
Executes
action
in a transaction, which means that all its queries and updates will be called atomically.inherited -
update<
Tbl extends Table, R> (TableInfo< Tbl, R> table) → UpdateStatement<Tbl, R> -
Starts an UpdateStatement for the given table. You can use that
statement to update individual rows in that table by setting a where
clause on that table and then use UpdateStatement.write.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
