psql access of user's environmental variables

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I need to use the value of an environment variable as part of an SQL query within psql.

I can do the following withing psql:

\set  local_site  `echo  $FXA_LOCAL_SITE

\echo  local site =  :local_site

The result is "local_site = xxx"  which is correct.

What I really want to do is the following:

\set  local_site  `echo  $FXA_LOCAL_SITE

UPDATE  table_name  SET  office_id =  :local_site;

This results in the message

              column  "xxx" does not exist

Is there any way that I can use the value of the FXA_LOCAL_SITE env variable in my UPDATE statement?
