next release:
|
||||
lateral since it is easy. I think it is effectively just a prefix
|
||||
operator on tablerefs (can appear like this from lateral a, from
|
||||
lateral a,b, from a, lateral b, from a natural join lateral b
|
||||
(although all of these are sematically garbage, this is the
|
||||
valid syntax)
|
||||
more dots: implement as dot operator
|
||||
|
||||
row ctor: row(a,b) is fine, but also when there is 2 or more elements,
|
||||
the word row can be omitted: (a,b)
|
||||
more symbolic operators, array access a[5]? don't think this is
|
||||
standard sql, if not, leave for now. There is something about
|
||||
arrays in sql:2008
|
||||
escapes in string literals
|
||||
|
||||
window frames and named windows
|
||||
|
||||
|
||||
review tests to copy from hssqlppp
|
||||
|
||||
order by nulls first/last
|
||||
extend case
|
||||
group by extensions. Question: some of the syntax can be represented
|
||||
by app and row ctor, should this be reused or new syntax created
|
||||
(the standard has special syntax for cube and rollup).
|
||||
table, values
|
||||
collate? -> postfix operator which binds very tightly:
|
||||
a < 'foo' collate 'C'
|
||||
->
|
||||
Op "<" [Iden "a", SpecialOp "collate" [StringLit 'foo', StringLit
|
||||
'C']]
|
||||
also postfix in order by:
|
||||
select a from t order by a collate 'C': add to order by syntax, one
|
||||
collation per column
|
||||
function table reference
|
||||
much more table reference tests, for joins and aliases etc.
|
||||
ansi standard versions of limit and offset
|

|

OFFSET start { ROW | ROWS }
