Question

i want to move a table to a new filegroup. Using the accepted answer as a starting point:

CREATE CLUSTERED INDEX CIX_YourTable
   ON dbo.YourTable(YourClusteringKeyFields)
   WITH DROP_EXISTING
   ON [filegroup_name]

i adapt it to my use:

CREATE CLUSTERED INDEX PK_AuditLog_AuditLogID
   ON dbo.AuditLog(AuditLogID)
   WITH DROP_EXISTING
   ON [TheOtherFileGroup]

gives the error:

Msg 1907, Level 16, State 1, Line 1
Cannot recreate index ‘PK_AuditLog_AuditLogID’. The new index definition does not match the constraint being enforced by the existing index.

This is, i assume, because PK_AuditLog_AuditLogID is

• a clustered index
• a primary key

So i need the syntax to create a primary key clustered index WITH DROP_EXISTING

Answer 1

CREATE UNIQUE CLUSTERED INDEX PK_AuditLog_AuditLogID
   ON dbo.AuditLog(AuditLogID)
   WITH DROP_EXISTING
   ON [TheOtherFileGroup]

The logical primary key constraint is preserved (though tested in 2012)

CREATE TABLE dbo.AuditLog
(
AuditLogID int constraint PK_AuditLog_AuditLogID primary key
)


CREATE UNIQUE CLUSTERED INDEX PK_AuditLog_AuditLogID
   ON dbo.AuditLog(AuditLogID)
   WITH DROP_EXISTING
   ON [Primary]



SELECT CONSTRAINT_TYPE  /*Returns PRIMARY KEY*/
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS
WHERE CONSTRAINT_NAME = 'PK_AuditLog_AuditLogID'
