Subject Re: How to specify the number of arguments in Aggregate functions
Date Thu, 25 Sep 2014 23:03:06 GMT
The "SqlOperandTypeChecker operandTypeChecker" argument to SqlAggFunction
determines the number and type of arguments that will be accepted. To date
all agg functions have accepted 1 argument (except 'COUNT(*)' which is
really 0 arguments) but it should work. OperandTypes.NUMERIC_NUMERIC might
be what you need.
