AggregateFunction (jOOQ 3.3.4 API)

All Superinterfaces:

Field<T>, GroupField, QueryPart, Serializable, WindowOverStep<T>

All Known Subinterfaces:

GroupConcatOrderByStep, GroupConcatSeparatorStep
```
public interface AggregateFunction<T>
extends Field<T>, WindowOverStep<T>
```
An aggregate function is a special field that is usually used in a GROUP BY context. It is also the base for window function construction.

  - over
```
@Support(value={CUBRID,DB2,POSTGRES,ORACLE,SQLSERVER,SYBASE})
