GetSchema() PrimaryKeys Collection does not exits

Hi!

I'm evaluating OraDirect.Net product but I got surprised when I did not find the PrimaryKeys Collection from GetSchema() method. The most Curious thing is that the Microsoft Native Oracle Provider has it. In the following lines you can see their differences...

UniqueKeys
PrimaryKeys << I Need this one
ForeignKeys
ForeignKeyColumns

Rather than the current GetSchema return collections, I really need this PrimaryKeys Collection. And unfortunatelly, In my case, I cannot assume Unique Index as PrimaryKeys.

Can you help me? Is there any way to get this PrimaryKeys Collection?

Kind regards,

Primary Keys collection has not been implemented in OracleConnection yet. We are working on this issue now. Alternatively, you can get PrimaryKeys in the following way:

OracleCommand selCom = new OracleCommand("select * from dept");
OracleDataTable dt = new OracleDataTable(selCom, connection);
dt.Active = true;
DataColumn[] dc = dt.PrimaryKey;
