* Create a new parsetree node type, TypeCast, so that transformation ofTom Lane2000-01-17
| | | | | | SQL cast constructs can be performed during expression transformation instead of during parsing. This allows constructs like x::numeric(9,2) and x::int2::float8 to behave as one would expect.
* Make number of args to a function configurable.Bruce Momjian2000-01-10

* Teach grammar and parser about aggregate(DISTINCT ...). No implementationTom Lane1999-12-10
| | | | | | | yet, but at least we can give a better error message: regression=> select count(distinct f1) from int4_tbl; ERROR: aggregate(DISTINCT ...) is not implemented yet instead of 'parser: parse error at or near distinct'.
* Add system indexes to match all caches.Bruce Momjian1999-11-22
| | | | | | | Make all system indexes unique. Make all cache loads use system indexes. Rename *rel to *relid in inheritance tables. Rename cache names to be clearer.
* New NameStr macro to convert Name to Str. No need for var.data anymore.Bruce Momjian1999-11-07
| | | | | | Fewer calls to nameout. Better use of RelationGetRelationName.
* Eliminate local inefficiencies in updateTargetListEntry, make_var, andTom Lane1999-11-01
| | | | make_const --- don't repeat cache searches that aren't needed.
* Rewrite parser's handling of INSERT ... SELECT so that processingTom Lane1999-07-19
| | | | | | | | | of the SELECT part of the statement is just like a plain SELECT. All INSERT-specific processing happens after the SELECT parsing is done. This eliminates many problems, e.g. INSERT ... SELECT ... GROUP BY using the wrong column labels. Ensure that DEFAULT clauses are coerced to the target column type, whether or not stored clause produces the right type. Substantial cleanup of parser's array support.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have attached a patch to allow GROUP BY and/or ORDER BY function or expressions. Note worthy items: 1. The expression or function need not be in the target list. Example: SELECT name FROM foo GROUP BY lower(name); 2. Simplified the grammar to use expressions only. 3. Cleaned up earlier patch in this area to make use of existing utility functions. 3. Reduced some of the members in the SortGroupBy parse node. The original data members were redundant with the new expression node. (MUST do a "make clean" now) 4. Added a new parse node "JoinUsing". The JOIN USING clause was overloading this SortGroupBy structure. With the afore mentioned reduction of members, the two clauses lost all their commonality. 5. A bug still exist where, if a function or expression is GROUPed BY, and an aggregate function does not include a attribute from the expression or function, the backend crashes. (or something like that) The bug pre-dates this patch. Example: SELECT lower(a) AS lowcase, count(b) FROM foo GROUP BY lowcase; *** BOOM *** --Also when not in target list SELECT count(b) FROM foo GROUP BY lower(a); *** BOOM AGAIN ***
* Cleanup makeTargetEntry and remove internal.c.Bruce Momjian1998-07-20

* Change atttypmod from int16 to int32, for Thomas.Bruce Momjian1998-07-12
|
* Allow floating point constants for "def_arg" numeric arguments.Thomas G. Lockhart1998-07-08
| | | | | | Used in the generic "CREATE xxx" parsing. Do some automatic type conversion for inserts from other columns. Previous trouble with "resjunk" regression test remains for now.
* Remove un-needed braces around single statements.Bruce Momjian1998-06-15
|
* I made several adjustments to my earlier patch to handle theBruce Momjian1998-06-05
| | | | condition where the target label is ambiguous.
* Do type conversion to match columns in UNION clauses.Thomas G. Lockhart1998-05-29
| | | | | | | | | | | Currently force the type to match the _first_ select in the union. Move oper_select_candidate() from parse_func.c to parse_oper.c. Throw error inside of oper_inexact() if no match for binary operators. Check more carefully that types can be coerced even if there is only one candidate operator in oper_inexact(). Fix up error messages for more uniform look. Remove unused code. Fix up comments.
* From: David Hartwig <daveh@insightdist.com>Marc G. Fournier1998-05-21
| | | | | Here is a patch to remove the requirement that ORDER/GROUP BY clause identifiers be included in the target list.
* Add capabilities for automatic type conversion.Thomas G. Lockhart1998-05-09

* Pass attypmod through to executor by adding to Var and Resdom.Bruce Momjian1998-02-10

* Parser cleanup.Bruce Momjian1998-01-20
| | | | Add lock to i386 asm.
* New pg_attribute.atttypmod for type-specific information likeBruce Momjian1998-01-16
| | | | | | | | | | | varchar length. Cleans up code so attlen is always length. Removed varchar() hack added earlier. Will fix bug in selecting varchar() fields, and varchar() can be variable length.
