public Class AvgWithArgumentCastFunction

extends AvgFunction
Class Inheritance
Imports
java.sql.Types
Some databases strictly return the type of the aggregation value for AVG which is problematic in the case of averaging integers because the decimals will be dropped. The usual workaround is to cast the integer argument as some form of double/decimal.
