VersionedVirtualTable class - versioned_schema library

Constructors

VersionedVirtualTable({required String entityName, required DatabaseConnectionUser attachedDatabase, required List<GeneratedColumn<Object> Function(String)> columns, required String moduleAndArgs, String? alias}): Create a small virtual table from the individual fields.
VersionedVirtualTable.aliased({required VersionedVirtualTable source, required String? alias}): Create a virtual table by copying fields from source and applying a alias to columns.

Properties

$columns → List<GeneratedColumn<Object>>: All columns from this table or view.
finalinherited
$primaryKey → Set<GeneratedColumn<Object>>: The primary key of this table. Can be empty if no custom primary key has been specified.
no setterinherited
actualTableName → String: The name of the table in the database. Unlike aliasedName, this can not be aliased.
no setterinherited
aliasedName → String: The (potentially aliased) name of this table or view.
no setterinherited
asDslTable → Table: Type system sugar. Implementations are likely to inherit from both TableInfo and Tbl and can thus just return their instance.
no setterinherited
attachedDatabase → DatabaseConnectionUser: The generated database instance that this view or table is attached to.
finalinherited
columnsByName → Map<String, GeneratedColumn<Object>>: Gets all $columns in this table or view, indexed by their (non-escaped) name.
no setterinherited
customConstraints → List<String>: Custom table constraints that should be added to the table.
finalinherited
dontWriteConstraints → bool: Drift will write some table constraints automatically, for instance when you override primaryKey. You can turn this behavior off if you want to. This is intended to be used by generated code only.
no setterinherited
entityName → String: The (unalised) name of this entity in the database.
finalinherited
hashCode → int: The hash code for this object.
no setterinherited
isStrict → bool: Whether this table is STRICT.
finalinherited
moduleAndArgs → String: Returns the module name and the arguments that were used in the statement that created this table. In that sense, CREATE VIRTUAL TABLE <name> USING <moduleAndArgs>; can be used to create this table in sql.
final
primaryKey → Set<Column<Object>>: Override this to specify custom primary keys:
no setterinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
tableName → String?: The sql table name to be used. By default, drift will use the snake_case representation of your class name as the sql table name. For instance, a Table class named LocalSettings will be called local_settings by default. You can change that behavior by overriding this method to use a custom name. Please note that you must directly return a string literal by using a getter. For instance @override String get tableName => 'my_table'; is valid, whereas @override final String tableName = 'my_table'; or @override String get tableName => createMyTableName(); is not.
no setterinherited
uniqueKeys → List<Set<GeneratedColumn<Object>>>: The unique key of this table. Can be empty if no custom primary key has been specified.
no setterinherited
withoutRowId → bool: Whether to append a WITHOUT ROWID clause in the CREATE TABLE statement. This is intended to be used by generated code only.
finalinherited

Methods

blob() → ColumnBuilder<Uint8List>: Use this as the body of a getter to declare a column that holds arbitrary data blobs, stored as an Uint8List. Example:
inherited
boolean() → ColumnBuilder<bool>: Use this as the body of a getter to declare a column that holds bools. Example (inside the body of a table class):
inherited
createAlias(String alias) → VersionedVirtualTable: Creates an alias of this table or view that will write the name alias when used in a query.
override
customType<T extends Object>(UserDefinedSqlType<T> type) → ColumnBuilder<T>: Defines a column with a custom type when used as a getter.
inherited
dateTime() → ColumnBuilder<DateTime>: Use this as the body of a getter to declare a column that holds date and time.
inherited
int64() → ColumnBuilder<BigInt>: Use this as the body of a getter to declare a column that holds a 64-big integer as a BigInt.
inherited
integer() → ColumnBuilder<int>: Use this as the body of a getter to declare a column that holds integers.
inherited
intEnum<T extends Enum>() → ColumnBuilder<int>: Creates a column to store an enum class T.
inherited
map(Map<String, dynamic> data, {String? tablePrefix}) → QueryRow: Maps the given row returned by the database into the fitting data class.
inherited
mapFromCompanion(Insertable<QueryRow> companion, DatabaseConnectionUser database) → Future<QueryRow>: Converts a companion to the real model class, D.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
real() → ColumnBuilder<double>: Use this as the body of a getter to declare a column that holds floating point numbers. Example
inherited
sqliteAny() → ColumnBuilder<DriftAny>: Use this as a the body of a getter to declare a column that holds arbitrary values not modified by drift at runtime.
inherited
text() → ColumnBuilder<String>: Use this as the body of a getter to declare a column that holds strings. Example (inside the body of a table class):
inherited
textEnum<T extends Enum>() → ColumnBuilder<String>: Creates a column to store an enum class T.
inherited
toString() → String: A string representation of this object.
inherited
validateIntegrity(Insertable<QueryRow> instance, {bool isInserting = false}) → VerificationContext: Validates that the given entity can be inserted into this table, meaning that it respects all constraints (nullability, text length, etc.).

Operators

operator ==(Object other) → bool: The equality operator.
