Do you need to DROP PARTITION SCHEME PS1?

Luzix · Answer

If you tries to delete a partition scheme and it´s being used there is a error:

The partition scheme "PS1" is currently being used to partition one or more tables.

I tried these:

CREATE TABLE dbo.SalesHistory
(
    Date_key INT NOT NULL,
    Customer_key INT NOT NULL,
    Amount MONEY 
) ON PS1(Date_key)
GO

ALTER TABLE Sales SWITCH PARTITION 1 TO dbo.SalesHistory PARTITION 1
GO

ALTER PARTITION FUNCTION PF1() MERGE RANGE (20120331)
GO

ALTER PARTITION SCHEME PS1 NEXT USED [FG1]
GO

ALTER PARTITION FUNCTION PF1() SPLIT RANGE (20121231)
GO
