Constructors

GeneratedDatabase(QueryExecutor executor, {StreamQueryStore? streamStore})
Used by generated code
GeneratedDatabase.connect(DatabaseConnection connection)
Used by generated code to connect to a database that is already open.

Properties

allSchemaEntities → Iterable<DatabaseSchemaEntity>
A list of all DatabaseSchemaEntity that are specified in this database.
no setter
allTables → Iterable<TableInfo<Table, dynamic>>
A list of tables specified in this database.
no setter
attachedDatabase → GeneratedDatabase
The database class that this user is attached to.
no setteroverride
connection → DatabaseConnection
The database connection used by this DatabaseConnectionUser.
finalinherited
executor → QueryExecutor
The executor to use when queries are executed.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
migration → MigrationStrategy
Defines the migration strategy that will determine how to deal with an increasing schemaVersion. The default value only supports creating the database by creating all tables known in this database. When you have changes in your schema, you'll need a custom migration strategy to create the new tables or change the columns.
no setter
options → DriftDatabaseOptions
The DriftDatabaseOptions to use for this database instance.
no setteroverride
resolvedEngine → DatabaseConnectionUser
A, potentially more specific, database engine based on the Zone context.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
schemaVersion → int
Specify the schema version of your database. Whenever you change or add tables, you should bump this field and provide a migration strategy.
no setteroverride
streamQueries → StreamQueryStore
Manages active streams from select statements.
no setterinherited
streamUpdateRules → StreamQueryUpdateRules
The collection of update rules contains information on how updates on tables result in other updates, for instance due to a trigger.
no setter
typeMapping → SqlTypes
A SqlTypes mapping configuration to use when mapping values between Dart and SQL.

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
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
beforeOpen(QueryExecutor executor, OpeningDetails details) → Future<void>
A callbacks that runs after the database connection has been established, but before any other query is sent.
override
close() → Future<void>
Closes this database and releases associated resources.
override
createMigrator() → Migrator
Creates a Migrator with the provided query executor. Migrators generate sql statements to create or drop tables.
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<Object>> variables = const [], Set<ResultSetImplementation>? updates}) → Future<int>
Executes a custom insert statement and returns the last inserted rowid.
inherited
customSelect(String query, {List<Variable<Object>> variables = const [], Set<ResultSetImplementation> readsFrom = const {}}) → Selectable<QueryRow>
Creates a custom select statement from the given sql query.
inherited
customSelectQuery(String query, {List<Variable<Object>> variables = const [], Set<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 ready readsFrom and use Selectable.watch. If you know the query will never emit more than one row, you can also use getSingle and watchSingle 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<Object>> variables = const [], Set<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 the updateKind 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<Object>> variables = const [], Set<ResultSetImplementation>? updates, UpdateKind? updateKind}) → Future<List<QueryRow>>
Runs a INSERT, UPDATE or DELETE 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<Table, dynamic>> tables) → void
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
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<Object>> columns) → Selectable<TypedResult>
Creates a select statement without a FROM clause selecting columns.
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 of table's columns.
inherited
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.
