Hi, I am using Cloudscape(IBM Cloudscape Version 10.1) and derbyclient.jar provided by derby. Following are the code I am using for clean the database connection and also PreparedStatement.
public void cleanup(Connection aoConnection, PreparedStatement aoPreparedStatement) { try{ if(!(aoConnection ==null || aoConnection.isClosed())) aoConnection.close();//Release Connection if(aoPreparedStatement != null) aoPreparedStatement.close(); }catch(SQLException aoSQLException){ aoSQLException.printStackTrace(); } } But some time this method call get hang. Can any one tell me why it is happening? I have one more problem with this database. I am updating a table using following code. //Table create script CREATE TABLE TABLE_MEMORY ( MEMORY_ID BIGINT NOT NULL GENERATED ALWAYS AS IDENTITY, MEMORY SMALLINT, PRIMARY KEY (MEMORY_ID) ); //JAVA Code Connection aoConnection = getConnection(); PreparedStatement psUpdate = aoConnection.prepareStatement("UPDATE TABLE_MEMORY SET MEMORY=? WHERE MEMORY_ID=?"); psUpdate.setInt(counter++, 38650); psUpdate.setInt(counter++, 15254); int updated = psUpdate.executeUpdate(); If I run above code, executeUpdate method does not throw any exception and always returns value 1. But, due to size of value I am setting (38650) is more than size of smallint, so it does not update database. Can any one tell me why value return by executeUpdate method is 1 even database update is failed? For any reply thanks in advance. Thanks & Regards Shambhu Kumar Sinha
