The primary key is made up of a smallint value that represents a Month and BIGINT a loan_number.--The partion key is a small int value.--I have tried the approach of selecting by the partition key, but as you can imagine because of the amount of data each select can take quite some time.--I also tried using an import\export task it started moving some data, but it is also extremly slow.--The new table has 24 partitions. each partition represents 24 values of the partition key from 0 - 552Here is the definition of the partitioned table. The heap table is the same except it does not have the identity column created_by\date attributes. --Partitioned table CREATE TABLE dbo.qc_partition( qc_partition_id BIGINT IDENTITY(1,1) , pool_id CHAR(3) NOT NULL, deal_no CHAR(5) NOT NULL, group_no CHAR(3) NOT NULL, servicer VARCHAR(4) NULL, internal_loan_id CHAR(6) NOT NULL, external_loan_id VARCHAR(18) NOT NULL, last_int_p SMALLDATETIME NULL, balance MONEY NULL, int_rate NUMERIC(6, 3) NULL, total_payment_due MONEY NULL, sched_principal MONEY NULL, sched_mnth_p MONEY NULL, mba_stat VARCHAR(1) NULL, ots_stat VARCHAR(1) NULL, payment_hist VARCHAR(12) NULL, exception VARCHAR(1) NULL, start_date SMALLDATETIME NULL, end_date SMALLDATETIME NULL, fc_end_typ VARCHAR(1) NULL, payoff_d SMALLDATETIME NULL, payoff_r VARCHAR(1) NULL, sell_date SMALLDATETIME NULL, inv_bal MONEY NULL, next_percent NUMERIC(6, 3) NULL, loss_val MONEY NULL, net_rate NUMERIC(7, 4) NULL, period SMALLINT NOT NULL, file_name CHAR(8) NOT NULL, created_by VARCHAR(70) NOT NULL DEFAULT CURRENT_USER , created_date DATETIME NOT NULL DEFAULT (GETDATE())) ON partition_scheme_qc (period) One more question about the indexing. I created the following index, but was wondering if anyone had better idea on that. Also, What would be the best way to create a clustered-index\primary key here.CREATE NONCLUSTERED INDEX IX_period_external_loan_idON qc_partition (period, external_loan_id)ON partition_scheme_qc (period)GODoes anyone have any ideas?Thank you for your helpWed, 09 Jan 2013 18:44:15 GMTmishka-723908
