COUNT(DISTINCT a.b)
#600New Features
count_distinct
inExpr
andFunc
which corresponds toCOUNT(DISTINCT a)
Changes
bool
parameter toFunctionCall
nameddistinct
which will keep track if theDISTINCT
modifier needs to be applied for the first argument.Note:
For now, adding the
distinct
parameter toFunctionCall
may seem like an overkill to support just one use case, but in the future more functions could be added that support theDISTINCT
modifier. Technically every aggregate function actually supports it but they are rarely used except forCOUNT
.
