Bruce Momjian	4a3a1e2cf1	Hi, ... small changes in formatting.c code (better memory usage ...etc.) and better to_char's cache (will fastly for more to_char()s in one query). (It is probably end of to_char() development in 7.0 cycle.) Karel	26 years ago
Bruce Momjian	eae5184d11	Hi, ... the to_char() source code is large, here are regression tests for numeric/timestamp/int8 part. It is probably enough test for formatting code in the formatting.c module. The others (float4/float8/int4) types share this formatting code and eventual bugs for these types aren't few probable. Patch fix timestamp_to_char() for infinity/invalid timestamp too. Karel	26 years ago
Thomas G. Lockhart	41f1f5b76a	Implement "date/time grand unification". ... Transform datetime and timespan into timestamp and interval. Deprecate datetime and timespan, though translate to new types in gram.y. Transform all datetime and timespan catalog entries into new types. Make "INTERVAL" reserved word allowed as a column identifier in gram.y. Remove dt.h, dt.c files, and retarget datetime.h, datetime.c as utility routines for all date/time types. date.{h,c} now deals with date, time types. timestamp.{h,c} now deals with timestamp, interval types. nabstime.{h,c} now deals with abstime, reltime, tinterval types. Make NUMERIC a known native type for purposes of type coersion. Not tested.	26 years ago
Bruce Momjian	394af52795	I'm sending patch with new version of to_char numbers formatting. ... The PostgreSQL's to_char() is very compatible with Oracle's to_char now. I hope that to_char's 3000 rows of source is without bugs, but will good if anyone test it, for me it works very well :-) Karel ---------------------------------------------------------------------- Karel Zak <zakkr@zf.jcu.cz> http://home.zf.jcu.cz/~zakkr/	26 years ago

Bruce Momjian	b866d2e2d7	as attache of this mail is patch (to the main tree) with to_char's ... family functions. Contain: conversion from a datetype to formatted text: to_char( datetime, text) to_char( timestamp, text) to_char( int4, text) to_char( int8, text) to_char( float4, text) to_char( float8, text) to_char( numeric, text) vice versa: to_date ( text, text) to_datetime ( text, text) to_timestamp ( text, text) to_number ( text, text) (convert to numeric) PostgreSQL to_char is very compatible with Oracle's to_char(), but not total exactly (now). Small differentions are in number formating. It will fix in next to_char() version. ! If will this patch aplly to the main tree, must be delete the current to_char version in contrib (directory "dateformat" and note in contrib's README), this patch not erase it (sorry Bruce). The patch patching files: doc/src/sgml/func.sgml ^^^^^^^^ Hmm, I'm not sure if my English... :( Check it anyone (volunteer)? Thomas, it is right? SGML is not my primary lang and compile the current PG docs tree is very happy job (hard variables setting in docs/sgml/Makefile --> HSTYLE= /home/users/t/thomas/.... :-) What add any definition to global configure.in and set Makefiles in docs tree via ./configure? src/backend/utils/adt/Makefile src/backend/utils/adt/formatting.c src/include/catalog/pg_proc.h src/include/utils/formatting.h Karel Zak <zakkr@zf.jcu.cz> http://home.zf.jcu.cz/~zakkr/	26 years ago
