Hello,
I have a problem with "ODatabaseMetaDataResultSet". I can't find any
documentation about it and I don't know how it works.
Do you mean the class in
connectivity/source/inc/FDatabaseMetaDataResultSet.hxx?
In that class all table structures are defined which you need to create
the correct resultset for every method of the databasemetadata which
returns a resultset.
E.g. When you have a look in source/drivers/odbc/ODatabaseMetaData.cxx
::getTableTypes there the resultset will be created and the correct
metadata for the resultset will be set.
::connectivity::ODatabaseMetaDataResultSet* pResult = new
::connectivity::ODatabaseMetaDataResultSet();
Reference< XResultSet > xRef = pResult;
pResult->setTableTypes(); // set metadata for the resultset ->
XResultSetMetaData
Afterwords the data is collected
::connectivity::ODatabaseMetaDataResultSet::ORows aRows;
for(sal_Int32 i=0;i < nSize;++i)
{
::connectivity::ODatabaseMetaDataResultSet::ORow aRow;
aRow.push_back(::connectivity::ODatabaseMetaDataResultSet::getEmptyValue());
// the first value must be this one
aRow.push_back(new
::connectivity::ORowSetValueDecorator(sTableTypes[i]));
aRows.push_back(aRow);
}
// set the data at the resultset
pResult->setRows(aRows);
// last but not least return it
return xRef;
The table structure (resultset structure) can be found in the
documentation of the com.sun.star.sdbc.XDatabaseMetaData
http://api.openoffice.org/docs/common/ref/com/sun/star/sdbc/XDatabaseMetaData.html#getTableTypes
I wanted to add table information to it in
ODatabaseMetaData::getTableType() to get the tables but it don't work.
My connection to the database works... but I can't see table-names in
oobase.
The getTableTypes method only return the types of tables supported by
the database. Returning "TABLE" and "VIEW" should be enough. See above.
When you want to see tables you have to implement getTables(...). You
may do something like that
// most classes already have a mutex like this one
::osl::MutexGuard aGuard( m_aMutex );
ODatabaseMetaDataResultSet* pResult = new ODatabaseMetaDataResultSet();
Reference< XResultSet > xRef = pResult;
// see
http://api.openoffice.org/docs/common/ref/com/sun/star/sdbc/XDatabaseMetaData.html#getTables
pResult->setTablesMap();
ODatabaseMetaDataResultSet::ORows aRows;
for(allMyTables)
{
ODatabaseMetaDataResultSet::ORow aRow(3);
// the first 3 values aren't needed so far (0,catalog, schema)
aRow.reserve(6);
aRow.push_back(new ORowSetValueDecorator(aName));
// TABLE NAME
aRow.push_back(new ORowSetValueDecorator(aTable));
// TABLE TYPE
aRow.push_back(ODatabaseMetaDataResultSet::getEmptyValue());
// REMARKS
aRows.push_back(aRow);
}
By the way...
Where can I get / include a MutexGuard that I can use in functions like
getTableType?
#ifndef _OSL_MUTEX_HXX_
#include <osl/mutex.hxx>
#endif
When you need a mutex in member initialization you must derive your
class in first place from ::cppu::BaseMutex so that the mutex is already
available when you want to use it.
#include <cppuhelper/basemutex.hxx>
Thanks,
André Klitzing
