- 所有超级接口:
- Bindable, SqlRenderable, TableFunction
- 所有已知子接口:
- AggregateFunction, ConversionFunction, DatetimeFunction, JsonFunction, LogicalFunction, NumberFunction, ScalarFunction, StringFunction, WindowsFunction
- 所有已知实现类:
- Abs, AbstractColumFunction, AllColumn, AnonymousFunction, AsBinary, AsText, Avg, Ceiling, Column, ColumnFunctionDecorator, Contains, Count, DateFormat, DenseRank, Distance, DistanceSphere, Distinct, Floor, JsonExtract, JsonUnquote, Latitude, Length, Longitude, Max, Md5, Min, Mod, Now, NumberColumn, Rank, Round, RowNumber, SRID, StdDev, SubString, Sum, Truncate, Upper, Variance
public interface ColumFunction
extends SqlRenderable, Bindable, TableFunction
一般情况下实现者不能直接实现该类,需要先继承AbstractColumFunction,因为AbstractColumFunction附带列运算
