get schema name

can some one pls tell me how to get the 'schema name' for a particular 'sequen开发者_JS百科ce' using jdbc

I assume you are using Oracle DB.
If that's the case you can run the query given below via JDBC and get the column named sequence_owner for the Schema Name to which a sequence belongs to.

SELECT sequence_owner
  FROM all_sequences
 WHERE sequence_name = '<YOUR_SEQUENCE_NAME>'

select SCHEMA_NAME from INFORMATION_SCHEMA.SCHEMATA

This is return all schema names.
