JDBC Metadata getPrimaryKey(....) method,Exception thrown Bug/Err?

[radhabalan]

Below is the code sniplet which is throwing an exception at the second line when used with a Type3 Teradata driver to connect to a Teradata database. Tried some other method getCatalogs() and it works fine.

DatabaseMetaData dbMetaData = con.getMetaData();
rs = dbMetaData.getPrimaryKeys(null, schema, name.toUpperCase());


Can anybody please suggest why its returing an error. Is it a bug in method implementation.

We tried two sets of Parameters for getPrimaryKeys(.,.,.)method
1. null, DatabaseName, TableName
2, Null, Null, DatabaseName.TableName


Help appreciated...

Thanks.
