1999-08-05Revise parse_coerce() to handle coercion of int and floatTom Lane
constants, not only string constants, at parse time. Get rid of parser_typecast2(), which is bogus and redundant...
1999-07-19Rewrite parser's handling of INSERT ... SELECT so that processingTom Lane
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.
1999-07-17 Move some system includes into c.h, and remove duplicates.Bruce Momjian
1999-07-16Support subscripts on bare column names.Tom Lane
1999-07-16Final cleanup.Bruce Momjian
1999-07-15Remove unused #includes in *.c files.Bruce Momjian
1999-07-11Ignore resjunk targetlist entries when matching arguments toTom Lane
a SubLink with the subplan's targetlist. This fixes a problem seen with, for example, a subselect that uses GROUP BY.
1999-05-26Make functions static or NOT_USED as appropriate.Bruce Momjian
1999-05-25pgindent run over code.Bruce Momjian
1999-05-22Fix for DEFAULT ''.Bruce Momjian
1999-05-18Add Aggref and ArrayRef to the set of node types that transformExprTom Lane
will pass through rather than spitting up. This is necessary to handle cases where coerce_type causes a subexpression to be retransformed, as in SELECT count(*) + 1.0 FROM table
1999-05-13Rip out QueryTreeList structure, root and branch. QuerytreeTom Lane
lists are now plain old garden-variety Lists, allocated with palloc, rather than specialized expansible-array data allocated with malloc. This substantially simplifies their handling and eliminates several sources of memory leakage. Several basic types of erroneous queries (syntax error, attempt to insert a duplicate key into a unique index) now demonstrably leak zero bytes per query.
1999-05-12Handle conversion of floating point constants to internal strings.Thomas G. Lockhart
1999-04-23Add disk space message to "can not extend" message.Bruce Momjian
1999-04-19Fix problems seen when result of a subselect was used in anTom Lane
expression context (ie, not at the top level of a WHERE clause). Examples like this one work now: SELECT name, value FROM t1 as touter WHERE (value/(SELECT AVG(value) FROM t1 WHERE name = touter.name)) > 0.75;
1999-04-18After transforming a CASE expr with a default argument,Tom Lane
delete the default argument from the node. This prevents the executor from spitting up on the untransformed argument expression. Typical failure was: select (case f1 when 'val' then 'subst' else f1 end) from t1; ERROR: copyObject: don't know how to copy 704
1999-02-03Cleanup of source files where 'return' or 'var =' is alone on a line.Bruce Momjian
1999-01-24Rename Aggreg to Aggref.Bruce Momjian
1998-12-13Improve CASE statement support.Thomas G. Lockhart
Try to label CASE columns for a SELECT if not specified with an AS clause.
1998-12-04Implement CASE expression.Thomas G. Lockhart
1998-10-02 the following little patch adds array references to queryBruce Momjian
parameters. With it applied a function like CREATE FUNCTION getname(oid8, int4) RETURNS name AS 'SELECT typname FROM pg_type WHERE oid = $1[$2]' LANGUAGE 'sql'; is possible. Mainly I need this to enable array references in expressions for PL/pgSQL. Complete regression test ran O.K. Jan
1998-10-01Fix for constbyval.Bruce Momjian
1998-09-01OK, folks, here is the pgindent output.Bruce Momjian
1998-09-01Renaming cleanup, no pgindent yet.Bruce Momjian
1998-07-12Change atttypmod from int16 to int32, for Thomas.Bruce Momjian
1998-07-08Allow floating point constants for "def_arg" numeric arguments.Thomas G. Lockhart
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.
1998-06-15Remove un-needed braces around single statements.Bruce Momjian
1998-05-29Do type conversion to match columns in UNION clauses.Thomas G. Lockhart
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.
1998-05-09Add capabilities for automatic type conversion.Thomas G. Lockhart
1998-04-26Re-apply Darren's char2-16 removal code.Bruce Momjian
1998-04-07Back out char2-char16 removal. Add later.Bruce Momjian
1998-03-30The following uuencoded, gzip'd file will ...Bruce Momjian
1. Remove the char2, char4, char8 and char16 types from postgresql 2. Change references of char16 to name in the regression tests. 3. Rename the char16.sql regression test to name.sql. 4. Modify the regression test scripts and outputs to match up. Might require new regression.{SYSTEM} files... Darren King
1998-03-26BETWEEN and LIKE patch from ThomasBruce Momjian
1998-02-27In '(a,b,...) Op [ANY|ALL] (SubSelect)' Op is restricted toVadim B. Mikheev
'=' and '<>'.
1998-02-26pgindent run before 6.3 release, with Thomas' requested changes.Bruce Momjian
1998-02-13gram.y: ALL_SUBLINK type was returned for x Op (subquery).Vadim B. Mikheev
parse_expr.c: only Op of bool type are supported currently...
1998-02-13Fix for EXISTS.Vadim B. Mikheev

1998-02-05Fix for varchar functions, and indextyple j-1 fix.Bruce Momjian
1998-02-03Parser cleanup for expr and subqueries.Bruce Momjian
1998-02-01Fix for psort. fixes regression tests.Bruce Momjian
1998-02-01AIX patch from Darren King and Univel patch from Billy Allie, mostlyBruce Momjian
related to grammar and parser issues, with one postmaster fix.
1998-01-20Add Var.varlevelup to code. More parser cleanup.Bruce Momjian
1998-01-20Parser cleanup.Bruce Momjian
Add lock to i386 asm.

1998-01-19Added code so SubLinks make it to optimizer.Bruce Momjian
1998-01-19Create SubLink nodes in parser for Vadim.Bruce Momjian
1998-01-16New pg_attribute.atttypmod for type-specific information likeBruce Momjian
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.
