Hi everyone,

we are reusing the SQL EMF model created in DTP, to perform some model
transformations. I noticed that DerivedTable has an attribute called
"queryExpression". However, no one seems to be setting it (nor I could
find calls to DerivedTable.setQueryExpression(QueryExpression)

We are interested in knowing, through this model, which is the query
that defines a View, so I guessed that may be the place to get it.

Can you confirm the implementation does no set this attribute? Is there
any chance to get it into the model?

Cheers,
Víctor.

Take a look at the parseView method in class DerbyDdlParser in plugin
org.eclipse.datatools.connectivity.apache.derby for an example where the
setQueryExpression is getting called. Also take a look at the
DerbyCatalogView and DerbyTableLoader classes.

Thanks Brian, I'll give it a look and see if it can be used for other
connectivity implementations :)
Cheers!
