Hello everybody, I am a SQL server DBA and I am planning to implement table partitioning on some of our large tables in our data warehouse. I am thinking to design it using the sliding window scenario. I do have one concern though; I think the staging tables we use for new data loading and for switching out the old partition are going to be non-partitioned, right?? Well, I don't have an issue with the second staging table that is used for switching out the old partition. My concern is on the first staging table that we use it for switch in purpose, since this table is non-partitioned and holding the new data, HOW ARE WE GOING TO USE/access THIS DATA FOR REPORTING PURPOSE before we switch in to our target partitioned table????? say, this staging table is holding a one month worth of data and we will be switching it at the end of the month. Correct me if I am wrong okay, one way I can think of accessing this non-portioned staging table is by creating views, which we dont want to change our codes.

Do you guys share us your thoughts, experiences???

We really appreciate your help.

Hi BG516,

According to your description, you need to implement table partitioning on some of our large tables in our data warehouse, the problem is that you need the partition table only hold a month data, please correct me if I have anything misunderstanding.

In this case, you can create non-partitioned table, import the records which age is more than one month into the new created table. Leave the records which age is less than one month on the table in your data warehouse Then you need to create job to copy the data from partition table into non-partitioned table at the last day of each month. In this case, the partition table only contain the data for current month. Please refer to the link below to see the details.
