Passing parameters to Oracle SQL file from Batch file

I have a SQL file that updates certain table. However, the table name depend on the machine name on which the software is installed. (Something like: TableFooBar-MyMachine). I have to write a batch file that calls an Oracle SQL script which will update this table.

So, BatchFile --> Update. Sql --> TableFooBar-MyMachine

The Update. Sql will have statement like: 

Update TableFooBar-<Machine-Name> where fooid = -99;

This batch file needs to run on many machines. There are actually many update statements on such tables. I do not want people to edit the sql files. Instead if I set the machine name in the batch file and pass it to the sql, I'm pretty much done! How do I pass the machine name parameter to the .sql file to achieve this?

Yes, you can do this, by creating the SQL file from the BATCH file.

It would look like this:

@echo off
set SQL = update.sql
ECHO connect username/password@database
ECHO Prompt Updating tables > %SQL%
ECHO Update TableFooBar-%1 where fooid = -99; >> %SQL%

sqlplus @update.sql

you can use substitution variables

update.sql

--
Update TableFooBar-&1 set column_foo='bar' where fooid = -99;
--

and then call

sqlplus foo/bar@db @update.sql <Machine-Name>
