= next release
|
|
|
|
Most important goal is to replace the fixity code and fix all the
|
|
bugs here.
|
|
|
|
== docs
|
|
|
|
add to website: pretty printed tpch, maybe other queries as
|
|
demonstration
|
|
|
|
add preamble to the rendered test page
|
|
|
|
add links from the supported sql page to the rendered test page for
|
|
each section
|
|
|
|
== testing
|
|
|
|
review tests to copy from hssqlppp
|
|
|
|
much more table reference tests, for joins and aliases etc.?
|
|
|
|
review internal sql collection for more syntax/tests
|
|
|
|
== features
|
|
|
|
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
|
|
have to do fixity for this to work
|
|
|
|
all ansi string literal syntax?
|
|
|
|
check ansi standard for operators
|
|
|
|
== other
|
|
|
|
change any/some/all to be proper infix operators like in
|
|
|
|
review syntax to replace maybe and bool with better ctors
|
|
maybe review some of the dodgy ast names like orderfield and inthing
|
|
|
|
|
|
|
|
= Later general tasks:
|
|
|
|
demo program: convert tpch to sql server syntax exe processor
|
|
|
|
dialect framework
|
|
try to implement fixity without the hse hack
|
|
source position annotation?
|
|
review abstract syntax (e.g. combine App with SpecialOp?)
|
|
|
|
more operators
|
|
|
|
sql server top syntax
|
|
|
|
named windows
|
|
|
|
extended string literals, escapes and other flavours (like pg and
|
|
oracle custom delimiters)
|
|
|
|
run through other manuals for example queries and features: sql in a
|
|
nutshell, sql guide, sql reference guide, sql standard, sql server
|
|
manual, oracle manual, teradata manual + re-through postgresql
|
|
manual and make notes in each case of all syntax and which isn't
|
|
currently supported also.
|
|
|
|
check the order of exports, imports and functions/cases in the files
|
|
fix up the import namespaces/explicit names nicely
|
|
|
|
do some tests for parse errors?
|
|
|
|
left factor parsing code in remaining places
|
|
|
|
quasi quotes?
|
|
|
|
ast checker: checks the ast represents valid syntax, the parser
|
|
doesn't check as much as it could, and this can also be used to
|
|
check generated trees. Maybe this doesn't belong in this package
|
|
though?
|
|
|
|
= sql support
|
|
|
|
proper character sets for identifiers, escapes, etc.
|
|
|
|
placeholder/positional arg
|
|
|
|
full number literals -> other bases?
|
|
apply, pivot
|
|
within group aggregate syntax
|
|
|
|
try to do full review of sql2003 query syntax
|
|
|
|
make ansi dialect which only supports ansi sql. Maybe there is a use
|
|
for a separate SQL 92, 99 and 2003 dialects?
|
|
|
|
other dialect targets:
|
|
postgres
|
|
oracle
|
|
teradata
|
|
ms sql server
|
|
mysql?
|
|
db2?
|
|
|
|
maybe later: other dml
|
|
insert, update, delete, truncate, merge + set, show?
|
|
copy, execute?, explain?, begin/end/rollback?
