Thread: Psql Internal Variable question
Hi,
I am trying to use psql \set and \echo commands to set some internal variables.
My variable starts with single quote and ends with single quote.
That is actual value of the variable.
Eg.
set cur_db 'pgdb'
\echo :cur_db
--I am expecting here 'pgdb' but psql shows pgdb
As mentioned above, I am expecting \echo to return 'pgdb' to me but it returns pgdb.
I tried using escape char, but it did not work.
Can somebody help me?

Thanks

Hello \set removes outer quotes if you use PostgreSQL 9.0 you can use \set xxx 'Pavel ''Stěhule' postgres=# \set AUTOCOMMIT = 'on' PROMPT1 = '%/%R%# ' PROMPT2 = '%/%R%# ' PROMPT3 = '>> ' VERBOSITY = 'default' VERSION = 'PostgreSQL 9.1beta1 on x86_64-unknown-linux-gnu, compiled by gcc (GCC) 4.5.1 20100924 (Red Hat 4.5.1-4), 64-bit' DBNAME = 'postgres' USER = 'pavel' PORT = '5432' ENCODING = 'UTF8' EDITOR_LINENUMBER_SWITCH = '+' HISTSIZE = '6000' HISTFILE = '~/.psql_history-5432' xxx = 'Pavel 'Stěhule' postgres=# \echo :'xxx' 'Pavel ''Stěhule' Regards Pavel 2011/6/1 Prafulla Tekawade <prafulla.tekawade@gmail.com>: > Hi, > > I am trying to use psql \set and \echo commands to set some internal > variables. > My variable starts with single quote and ends with single quote. > That is actual value of the variable. > > Eg. > set cur_db 'pgdb' > \echo :cur_db > --I am expecting here 'pgdb' but psql shows pgdb > > As mentioned above, I am expecting \echo to return 'pgdb' to me but it > returns pgdb. > I tried using escape char, but it did not work. > Can somebody help me? > > > > -- > Thanks > Prafulla >
