Oracle: dynamically select script

Question

How do I run a script in SQLPlus whose pathname is passed in a string. Something like the following (fails):

SET SERVEROUTPUT ON;
DECLARE
   path VARCHAR2(128);
BEGIN
   path := '<runtime_path>' || 'test_script.sql';
   dbms_output.put_line(path);
   @ path;
END;
/

Answer 1

You can pass a parameter to SQLPlus but you cannot mix PL/SQL with SQLPlus commands. So your example will not fly. So you might need to wrap it with a shell script. But as I look at your PL/SQL routine you just try to add the path. Maybe this is possible though.

Call sqlplus like this

sqlplus user/password@database @genericscript.sql path

And then within genericscript.sql

SET SERVEROUTPUT ON
start &1.myscript.sql
quit

In my example the myscript.sql has this content

select 'hello welt' from dual;

So I got the following output from SQLPlus

[oracle@localhost sqp]$ sqlplus user/pw@db @genericscript.sql /home/oracle/sqp/

Hope it helps. You can have a look at the SQLPLUS reference manual.

I prefer the PDF

One option:

D:\>type run.sql
col p new_value path noprint
select '&1.' as p from dual
/

@&path
D:\>type run1.sql
select 'This is run1' from dual
/
D:\>sqlplus hr/hr@sandbox @run.sql d:\run1.sql

This is run1

And you can inline scripts in anonymous blocks too, very convenient:

D:\>sqlplus hr/hr@sandbox @parent.sql d:\child.sql

The way I do it on Windows is creating a BAT file containing:

sqlplus my_username/my_password@tns.test.company.com %*

Then from the command prompt, to execute the SQL-contents of a file, I just type:

batfile.bat @myfile.sql

The only way to run an executable from PL/SQL is to dynamically create a scheduler program of type EXECUTABLE and schedule a job.
