Disable wrapping in Psql output

由 ☆樱花仙子☆ 提交于 2019-12-03 14:38:13
问题 When using Psql in Linux, if the result of my SQL query contains many columns or long strings of data, it will wrap the initial view and only once I scroll to the side will it stop wrapping and show each row on a separate line. I've tried various \pset options such as format unaligned , format aligned , format wrapped , columns 0 , columns 1000 , but none seemed to fully stop wrapping unless I generate static output to a file. How can I set it to never wrap the output while still being

问题 I'm trying to import a (rather large) .txt file into a table geonames in PostgreSQL 9.1. I'm in the /~ directory of my server, with a file named US.txt placed in that directory.

I then enter this query: COPY geonames FROM 'US.txt', DELIMITER E'\t', NULL 'NULL'); I then receive this error: ERROR: could not open file "US.txt" for reading: No such file or directory. Do I have to type in \i US.txt or something

PostgreSQL user listing

问题 I want to get a list of users for a certain database in psql - for example "template0". Who are the users? Or for "template1" database: - who are the users there? Already tried: \du+ -- no database is Listed not Users Select * from "pg_users"; -- no database is listed 回答1: User aren't actually, "for the database", they're for cluster and are given different permissions to access databases. To list users \du should do, but you need to be connected. Something like psql template1 -c '\du' from

How to select a schema in postgres when using psql?

由 家住魔仙堡 提交于 2019-12-03 01:45:06
问题 I have a postgres database with multiple schemas. When I connect to the database from a shell with psql and I run \dt it uses the default connection schema which is public . Is there a flag I can specify or how can I change the schema? 回答1: In PostgreSQL the system determines which table is meant by following a search path, which is a list of schemas to look in. The first matching table in the search path is taken to be the one wanted, otherwise, if there is no match a error is raised, even

customize pager in psql

由 。_饼干妹妹 提交于 2019-12-02 23:46:42
When I use psql , the command line tool of PostgreSQL, in interactive mode, it lists data as paginated output. However, because I use psql in a terminal application which can handle long outputs itself, I rather would like to get the whole output without the paginating with the annoying --more-- line. Is there any way to customise the paging behavior in psql ? I tried to set LESS in the surrounding shell environment to cat , but this din't help. Any suggestions? From the fine psql manual : \pset option [ value ] [...] pager Controls use of a pager program for query and psql help output. If the

psql return code if zero rows found

由 霸气de小男生 提交于 2019-12-02 21:31:25
问题 I would like for my psql command to fail if zero rows are found: psql -U postgres -d db -c "select * from user where id=1 and name='Joe';" I want to be able to check the return value. Return 0 from the process(!) if at least one row exists and return non-zero from the psql process if no such row exists. How can I set a return code if no rows are found? 回答1: I don't think psql can do it by itself, but if you just want to see if there are any rows or not with the exit status you could combine
