I created a user defined function in ClickHouse and I can use it in my queries, it works fine, but I cannot use it in updating a column.
Is there a config I am missing? Shouldn’t it work for update too?

Here is how I use it in my update query:

ALTER TABLE table1 UPDATE column2 = func1(column1) WHERE 1;

And here is what I get:

Code: 46. DB::Exception: Received from localhost:9000. DB::Exception: Unknown function func1: While processing func1(column1). (UNKNOWN_FUNCTION)
