Subject Re: How to script database upgrade using ANT script
Date Thu, 04 Nov 2010 16:45:37 GMT
Hi,

you will need to use the <exec/> task for steps like creating the 
database and importing the dump into the new schema.
Once your database is up, you can use the <sqlexec/> task to run DDL and 
DML statements.
To check whether a script exists, there is a task called <available/> 
which can set a property if a file is available.
For error checking, you can run <exec/> with failonerror="true" to stop 
your build if a script fails.
You need to test before hand whether the system commands or the scripts 
that you will run to create the database and import the dump are 
returning proper exit statuses. (setting ERRORLEVEL on Windows or $? on 
UNIX).

Regards,

Antoine
