Question

I have a table ‘X’ and did the following

1. CREATE PARTITION FUNCTION PF1(INT) AS RANGE LEFT FOR VALUES (1, 2, 3, 4)
2. CREATE PARTITION SCHEME PS1 AS PARTITION PF1 ALL TO ([PRIMARY])
3. CREATE CLUSTERED INDEX CIDX_X ON X(col1) ON PS1(col1)

this 3 steps created 4 logical partitions of the data I had.

My question is, how do I revert this partitioning to its original state ?

Answer 1

After 2 days of continuous searching

The Steps:

1. DROP INDEX CIDX_X on X /* drop the clustered */
2. CREATE CLUSTERED INDEX CIDX_X1 ON X(col1) ON [PRIMARY] /* Create another clustered index on the table to free it from the partitioning scheme; Here, the “ON [primary]” part is key to removing the partition scheme from the table ! */
3. DROP PARTITION SCHEME PS1
4. DROP PARTITION FUNCTION PF1
5. DROP INDEX CIDX_X1 ON X /* drop the dummy clustered index you created, as it was only created to free the table from the partitioning scheme */
