Question

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?

Answer 1

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>
