REQUEST
I want to get a value of the specific environment variable by querying a database.
SOLUTION
First, define a variable
oracle@dbpilot.net: export MYVAR="My Variable"
oracle@dbpilot.net: echo $MYVAR
My Variable
A value of any variable can be retrieved through DBMS_SYSTEM.GET_ENV procedure
COL OS_VAR FOR A30
VARIABLE OS_VAR VARCHAR2(50);
EXEC DBMS_SYSTEM.GET_ENV('MYVAR',:OS_VAR);
SQL> PRINT OS_VAR;
OS_VAR
------------------------------
My Variable
Version : 14:53 19.01.2018
Database : Oracle database 10g – 12cR2
