Everyone has some way to inititalize variables in SQL*PLUS. My favorite is to use the "col" directive with "new_val" option. This approach does not require a spoolfile making it somewhat easier to use in SQL*PLUS coding choirs.
-- Here is one way to set an ARCHIVE_KEY variable --=============================================== -- Clear the variable undefine ARCHIVE_KEY ; -- Set the column to define col ARCHIVE_KEYval new_val ARCHIVE_KEY -- Select and initialize the variable -- **** -- NOTE: This is my format of ARCHIVE_KEY. -- You can change the format as needed. select to_char(sysdate ,'YYYYMMDD_HH24MISS') ARCHIVE_KEYval from dual; -- This is just to display the value select '&&ARCHIVE_KEY' ARCHIVE_KEY from dual ; --eof--
