Property
Data Type or Allowed Values
Description
ANALYTIC
'TRUE'|'FALSE'
indicates the aggregate function must be windowed. default false.
ALLOWS-ORDERBY
'TRUE'|'FALSE'
indicates the aggregate function supports an ORDER BY clause. default false
ALLOWS-DISTINCT
'TRUE'|'FALSE'
indicates the aggregate function supports the DISTINCT keyword. default false
DECOMPOSABLE
'TRUE'|'FALSE'
indicates the single argument aggregate function can be decomposed as agg(agg(x) ) over subsets of data. default false
USES-DISTINCT-ROWS
'TRUE'|'FALSE'
indicates the aggregate function effectively uses distinct rows rather than all rows. default false
Note that virtual functions defined using the Teiid procedure language cannot be aggregate functions.

Note

If you have defined a UDF (virtual) function without a Teiid procedure definition, then it must be accompanied by its implementation in Java. To configure the Java library as dependency to the VDB, see Support for User-Defined Functions in Red Hat JBoss Data Virtualization Development Guide: Server Development.
