Methods

constructQuery() → GenerationContext
Constructs the query that can then be sent to the database executor.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
replace(Insertable<D> entity, {bool dontExecute = false}) → Future<bool>
Replaces the old version of entity that is stored in the database with the fields of the entity provided here. This implicitly applies a where clause to rows with the same primary key as entity, so that only the row representing outdated data will be replaced.
toString() → String
A string representation of this object.
inherited
where(Expression<bool> filter(T tbl)) → void
Makes this statement only include rows that match the filter.
inherited
whereSamePrimaryKey(Insertable<D> d) → void

Available on SingleTableQueryMixin<T, D>, provided by the QueryTableExtensions extension

Applies a where statement so that the row with the same primary key as d will be matched.
write(Insertable<D> entity, {bool dontExecute = false}) → Future<int>
Writes all non-null fields from entity into the columns of all rows that match the where clause. Warning: That also means that, when you're not setting a where clause explicitly, this method will update all rows in the table.
writeInto(GenerationContext context) → void
Writes this component into the context by writing to its GenerationContext.buffer or by introducing bound variables. When writing into the buffer, no whitespace around the this component should be introduced. When a component consists of multiple composed component, it's responsible for introducing whitespace between its child components.
inherited
writeReturning(Insertable<D> entity) → Future<List<D>>
Applies the updates from entity to all rows matching the applied where clause and returns affected rows after the update.
writeStartPart(GenerationContext ctx) → void
Subclasses must override this and write the part of the statement that comes before the where and limit expression..
override

Operators

The equality operator.
