Hi Dave,
"catalogs" are the same as "databases" I think. Basically, typing \l at the psql prompt will list them. The MySQL
driverlists all the databases when getCatalogs() is called (by the way, Peter E has implemented it in
DatabaseMetaData.getCatalogs()when I requested it - see CVS). I think maybe the name is just confusing?
Methods like Connection.getCatalog() should return the database which the driver is currently connected to.
Connection.setCatalog(Stringdatabase) should connect to the specified database. The
DatabaseMetaData.supportsCatalogsInXXX()may need to be modified. I'm not sure about the stuff in
DatabaseMetaData.getTables()for example - at the moment specifying null gets all the tables in the database which the
driveris currently connected to. I think this is fine - but different database name patterns might be specified and
theymay have to be implemented?
The MySQL driver implements get/setCatalog() as well as getCatalogs(). Supporting catalogs is necessary for my database
toolto list the databases available etc.
Thanks,
Jason Davies
