Error Code

S02050

Error Message

The "select" clause does not support the following functions: aggregate, order-sensitive, row reduction, and null-filling functions. RefId: S02050

Probable Causes

In a pivot by query, this error occurs when the following functions are applied to the query column:

Aggregate functions
Order-sensitive functions (e.g. rowSum)
Row-based functions (e.g. rowSum)
Null-filling functions (e.g. ffill)

time = [10:20:44,10:20:44,10:20:44,10:20:45,10:20:45,10:20:45,10:20:46,10:20:46,10:20:46,10:20:46,10:20:46,10:20:46]
sym = ["A","B","C","A","B","C","A","B","C","A","B","C"]
value = [510,434,999,837,402,615,495,885,745,968,975,165]
t = table(time,sym,value)

db = database("dfs://test_pivot",VALUE,`A`B`C)
pt = db.createPartitionedTable(t,`pt,`sym)
pt.append!(t)

select sum(asis(value)) from pt pivot by time,sym
select cumsum(asis(value)) from pt pivot by time,sym
select rowSum(asis(value)) from pt pivot by time,sym
select ffill(asis(value)) from pt pivot by time,sym
=> The 'select' clause does not support the following functions: aggregate, order-sensitive, row reduction, and null-filling functions.

Solutions

Ensure that the afore-mentioned functions are not applied to the query column in a pivot by query.

Additionally, the conditions for the combined use of asis and pivot by specified in pivot by should also be met.
