Question

I wrote a script that creates some tables (it previously drops them if they exist) and then tries to create two indexes on each table.

The first index uses the Primary Key column to create a non-clustered index, and the second uses another column to create the clustered indexed. This is because the primary key column is a GUID instead of an int.

How can I drop the default index if I don’t know it’s name? or how can I specify a name for the primary key column index so I can drop it? Or better yet, how can I specify the 2 index i need right in the Create Table statement?

SELECT * FROM sys.indexes

However, I’m not understanding where in your process you actually have to drop an index.

You said you are creating some tables and then creating two indexes on each table.

If you are DROPping existing tables at the beginning, any indexes are automatically dropped.

There is no such thing as a default index.

Tables can either be heaps or clustered indexes. If you drop the clustered index, the table will be converted to a heap and any non-clustered indexes will have to be updated to point to the data in the unordered heap.

You can create like this all at once:

CREATE TABLE dbo.tbl
(
    Id int NOT NULL IDENTITY (1, 1) CONSTRAINT UK_ID UNIQUE CLUSTERED,
    SomeUUID UNIQUEIDENTIFIER NOT NULL CONSTRAINT PK_SomeUUID PRIMARY KEY NONCLUSTERED
)
