I know that I can run an sql file directly from the command line as follows:
/sql -LOGON user/password@tnsname ./scripts/sql_script.sql parameter1
And I know that I can call a javascript program from within the sqlcl shell as follows:
/sql>script scripts/js_script.js &1
The question is do I have to use the sql-wrapper script, or how can I run the javascript directly from the command line without the wrapper as follows:
/sql -LOGON user/password@tnsname ./scripts/js_script.js parameter1
How have I not made that possible yet?? It's now on my todo list..
In the meantime you could do something like this.
