Обсуждение: Solution proposal for TODO item "Clients: sequences"
Dear People, Hereby a proposal for the TODO item "Clients: Have psql show current values for a sequences". I have added a new slash command to psql client "\sq" for showing the last values of the existing sequences in the public schema. The code is only tested on rh9. The new files are sequence_info.c and sequence_info.h I would like to hear your comments. (Be gentle this is my first) The sources can be downloaded from http://www.truesoftware.net/psql/ Regards, Gevik ---------------------------------------------------------------- SCREEN OUTPUT ---------------------------------------------------------------- [gevik@voyager psql]$ ./psql Welcome to psql 8.0.0beta5, the PostgreSQL interactive terminal. Type: \copyright for distribution terms \h for help with SQL commands \? for help with psql commands \g orterminate with semicolon to execute query \q to quit gevik=# \sq Current sequence valuesSequence | Last value -----------+------------mytableid | 5seq1 | 1 (2 rows) gevik=#
That would be something good for 8.1 so I will keep your email.

It would be nice to add the current sequence value to \ds, but the existing psql query would have to be overhauled to do that. Right now the same query does all the work for most \d commands. --------------------------------------------------------------------------- Gevik Babakhani wrote: > Dear People, > > Hereby a proposal for the TODO item "Clients: Have psql show current values > for a sequences". > I have added a new slash command to psql client "\sq" for showing the last > values of the > existing sequences in the public schema.

So what would be your suggestion in order to add this functionality? -----Original Message----- From: pgsql-hackers-owner@postgresql.org [mailto:pgsql-hackers-owner@postgresql.org] On Behalf Of Bruce Momjian Sent: Sunday, June 05, 2005 3:17 AM To: Gevik Babakhani Cc: Pgsql-Hackers@Postgresql.

I would suggest adding it to \ds or create a \ds+ so that it is in common with the rest of the commands. -Jonah Gevik babakhani wrote: >So what would be your suggestion in order to add this functionality? > > >-----Original Message----- >From: pgsql-hackers-owner@postgresql.org >[mailto:pgsql-hackers-owner@postgresql.org] On Behalf Of Bruce Momjian >Sent: Sunday, June 05, 2005 3:17 AM >To: Gevik Babakhani >Cc: Pgsql-Hackers@Postgresql.
