Methods

batch() → Batch

Creates a batch, used for performing multiple operation in a single atomic operation.

delete(String table, {String? where, List<Object?>? whereArgs}) → Future<int>

Convenience method for deleting rows in the database.

execute(String sql, [List<Object?>? arguments]) → Future<void>

Execute an SQL query with no return value.

insert(String table, Map<String, Object?> values, {String? nullColumnHack, ConflictAlgorithm? conflictAlgorithm}) → Future<int>

This method helps insert a map of values into the specified table and returns the id of the last inserted row.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

query(String table, {bool? distinct, List<String>? columns, String? where, List<Object?>? whereArgs, String? groupBy, String? having, String? orderBy, int? limit, int? offset}) → Future<List<Map<String, Object?>>>

This is a helper to query a table and return the items found. All optional clauses and filters are formatted as SQL queries excluding the clauses' names.

queryCursor(String table, {bool? distinct, List<String>? columns, String? where, List<Object?>? whereArgs, String? groupBy, String? having, String? orderBy, int? limit, int? offset, int? bufferSize}) → Future<QueryCursor>

See DatabaseExecutor.rawQueryCursor for details about the argument bufferSize See DatabaseExecutor.query for the other arguments.

rawDelete(String sql, [List<Object?>? arguments]) → Future<int>

Executes a raw SQL DELETE query and returns the number of changes made.

rawInsert(String sql, [List<Object?>? arguments]) → Future<int>

Executes a raw SQL INSERT query and returns the last inserted row ID.

rawQuery(String sql, [List<Object?>? arguments]) → Future<List<Map<String, Object?>>>

Executes a raw SQL SELECT query and returns a list of the rows that were found.

rawQueryCursor(String sql, List<Object?>? arguments, {int? bufferSize}) → Future<QueryCursor>

Executes a raw SQL SELECT with a cursor.

rawUpdate(String sql, [List<Object?>? arguments]) → Future<int>

Executes a raw SQL UPDATE query and returns the number of changes made.

toString() → String

A string representation of this object.

inherited

update(String table, Map<String, Object?> values, {String? where, List<Object?>? whereArgs, ConflictAlgorithm? conflictAlgorithm}) → Future<int>

Convenience method for updating rows in the database. Returns the number of changes made
