RE: get the SQL to be executed
Perhaps you can use the log output (with some tweaks to the log4j configuration). However I'm not sure how and if Torque 3.3 logs the update statements. But then again I've heard of drivers which at as a bridge between the application and the real driver (e.g http://www.squirrelsql.org/) and which can do the logging for you. Torque 4 will not work because it uses prepared statements for updates, this will not give you any sensible sql.

You can use a logging driver such as p6spy to see your SQL statements. http://sourceforge.net/projects/p6spy/ On 19 January 2012 08:25, Thomas Fox wrote: > Perhaps you can use the log output (with some tweaks to the log4j > configuration).

RE: get the SQL to be executed
If you are trying to generate an initial data scripts rather than a "audit log", you might look at the dumpdata and datasql tasks that Torque supplies. I have used these to create initial data sets that applications need (e.g. initial user entry, rights entry, etc.) If you need to do this inside the code, you might look at the apache ddlutils project db.apache.com/ddlutils. This has some code callable functions to generate various SQL scripts. If you don't need SQL, but are really looking for a way to export/import data between Torque applications, look at sf.net/projects/torque-addons. This has a framework for easily creating XML exports of records. You may need to write some record handler code to deal with foreign keys.

Re: get the SQL to be executed
Thanks all for your responses. Just to clarify, I need to generate sql commands inside my code to generate a file that can be used by another software (not written by me) to import data. I would like not to execute commands but only write them (because this is what I need). If I cannot find alternatives, I can execute them and use one of the logging facilities that have been suggested.

Well, inserts are sort of tricky because the actual SQL generation happens deep inside Village. If you have control over your class loader, you may modify a copy of the com.workingdogs.village.Record class and put that first in the chain. Look for the saveWithInsert() method. This is probably the closest you can get, IMHO. Bye, Thomas. - To unsubscribe, e-mail: torque-user-unsubscr...@db.apache.org For additional commands, e-mail: torque-user-h...@db.apache.org
RE: get the SQL to be executed
Or, if the info you're exporting maps to your Torque app's
tables, you could probably just add "toSQL()" methods to
the record stubs that creates the INSERT statements.
E.g. if you have a User record object, modify the User.java
Torque created with something like:
Public String toSQL() {
StringBuffer sql = new StringBuffer;
// Build SQL statement from current object contents
return sql.toString();
}
Then just do a normal Torque query to get the data you're
interested in and loop thru the results calling toSQL to
create your output file.
Note that once the "stub" classes are built, Torque will not
replace them if your regenerate the code. So the toSQL() code
is safe.
It would also be possible to create some generic Torque record to
SQL code by using the "map" information. This lets you determine
the column info in a table. So you could look up the table info
for a record object, then create the sql by iterating over the
column names and using the column type to determine the string
format to use.
But for a few table objects, it might be easier to just do the
manually created toSQL() methods.
