getColumns() method on Databasemetadata returns empty for table synonyms

[Bhagya Tangutur]

How can i get Information about table columns from TableSynonym.
getColumns name in DatabaseMetadata returns empty result set for tableSynonyms.

because of security restrictions and for easy database maintainence i should not use table names itself.

I am using following method to check number of columns in Table synonym.
passing tableSynonym for tableName pattern argument.

getColumns(String catalog, String schemaPattern, String tableNamePattern, String columnNamePattern)
Retrieves a description of table columns available in the specified catalog.

Do you guys suggest any work around to get Columns associated with real table from its synonym.

What database backend and driver are you using? I've not seen this problem with views but it may be a driver issue.

i am using Oracle thin driver.
Infact i am able to retrieve columns for table synonym,i set the property setINcludeSynonyms(true) on
oracle.jdbc.driver.OracleConnection from ther eit works fine.

Now when i am trying to get Primary keys through table synonym.I am getting
empty result set for it.Please let me know if you have any solution for it.

Thanks
