Julian Hyde commented on CALCITE-6970:
--------------------------------------
Could the summary just be 'In UPDATE, allow SET to assign to multiple columns'?
We shouldn't just change the parser; we should change the parser, validator,
sql-to-rel converter so that we can execute such queries (e.g. in Quidem
scripts). And have validation tests where 'update ... set (x,x) =' and 'update
... set (x,y,z) = (select a,b ...' give good error messages.
> The parser should support that the sql update multiple fields with a source
> select
