sql question

2002-03-12 22:58

Is it possible to add SQL commands before and after the query string?


Use Case: I would like to issue commands to create temporary tables, for praticular views, to allow joins durring the query... And then delete those temporary tables after the report is done running...


But I would like to issue these SQL commands in the XML file, so there part of the report.


Thanks, tim

I have posted an answer to this in the other thread:

I can't get there either. This thread is quite stale, but useful as a historical reference, so I'll mention that this thread:


addresses the question, albeit briefly.

The query executer provided by JasperReports, JRJdbcQueryExecuter, calls PreparedStatement.executeQuery, which can only do selects, not updates or table creation. In that other thread Teodor suggests creating a "custom query executer" that could add some intelligence to the built-in query executer. "The Definitive Guide to JasperReports" talks about this in Chapter 8 in the section "Query Executer API."
