ColumnBuilder<T extends Object> class

A column builder is used to specify which columns should appear in a table. All of the methods defined in this class and its subclasses are not meant to be called at runtime. Instead, the generator will take a look at your source code (specifically, it will analyze which of the methods you use) to figure out the column structure of a table.

Methods

autoIncrement() → ColumnBuilder<BigInt>

Available on ColumnBuilder<BigInt>, provided by the BuildInt64Column extension

Enables auto-increment for this column, which will also make this column the primary key of the table.
autoIncrement() → ColumnBuilder<T>

Available on ColumnBuilder<T>, provided by the BuildIntColumn extension

Enables auto-increment for this column, which will also make this column the primary key of the table.
call() → Column<T>

Available on _BaseColumnBuilder<T>, provided by the BuildGeneralColumn extension

Turns this column builder into a column. This method won't actually be called in your code. Instead, the generator will take a look at your source code to figure out your table structure.
check(Expression<bool> condition) → ColumnBuilder<T>

Available on ColumnBuilder<T>, provided by the BuildColumn extension

Adds a CHECK constraint to this column.
clientDefault(T onInsert()) → ColumnBuilder<T>

Available on ColumnBuilder<T>, provided by the BuildColumn extension

Sets a dynamic default value for this column.
customConstraint(String constraint) → ColumnBuilder<T>

Available on ColumnBuilder<T>, provided by the BuildColumn extension

Tells drift to write a custom constraint after this column definition when writing this column, for instance in a CREATE TABLE statement.
generatedAs(Expression<T> generatedAs, {bool stored = false}) → VirtualColumnBuilder<T>

Available on ColumnBuilder<T>, provided by the BuildColumn extension

Declare a generated column.
map<Dart>(TypeConverter<Dart, T?> converter) → ColumnBuilder<T>

Available on _BaseColumnBuilder<T>, provided by the BuildGeneralColumn extension

Uses a custom converter to store custom Dart objects in a single column and automatically mapping them from and to sql.
named(String name) → ColumnBuilder<T>

Available on _BaseColumnBuilder<T>, provided by the BuildGeneralColumn extension

By default, the field name will be used as the column name, e.g. IntColumn get id = integer() will have "id" as its associated name. Columns made up of multiple words are expected to be in camelCase and will be converted to snake_case (e.g. a getter called accountCreationDate will result in an SQL column called account_creation_date). To change this default behavior, use something like IntColumn get id = integer((c) => c.named('user_id')).
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
nullable() → ColumnBuilder<T>

Available on _BaseColumnBuilder<T>, provided by the BuildGeneralColumn extension

Marks this column as nullable. Nullable columns should not appear in a primary key. Columns are non-null by default.
references(Type table, Symbol column, {KeyAction? onUpdate, KeyAction? onDelete, bool initiallyDeferred = false}) → ColumnBuilder<T>

Available on ColumnBuilder<T>, provided by the BuildColumn extension

Adds a foreign-key reference from this column.
toString() → String
A string representation of this object.
inherited
unique() → ColumnBuilder<T>

Available on _BaseColumnBuilder<T>, provided by the BuildGeneralColumn extension

Adds UNIQUE constraint to column.
withDefault(Expression<T> e) → ColumnBuilder<T>

Available on ColumnBuilder<T>, provided by the BuildColumn extension

The column will use this expression when a row is inserted and no value has been specified.
withLength({int? min, int? max}) → ColumnBuilder<T>

Available on ColumnBuilder<T>, provided by the BuildTextColumn extension

Puts a constraint on the minimum and maximum length of text that can be stored in this column.

Operators

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