Question

I’m using sql server 2005/2008 and I have a table that it’s PK (rec_index) is also indexed.

CREATE TABLE [dbo].[MyTable] 
(
    [rec_index] INT IDENTITY(1,1) PRIMARY KEY CLUSTERED,
    file_desc nvarchar(50),
    is_modified bit
)

However unfortunately I already have a table like this in my DB which O created without the index.

How can I ask if the table already is indexed do nothing, else add an index? I can’t drop it and than re-create it since i will loose data.

I’m looking for something like "if not exists <index for rec_index> do <create index for rec_index>"

Answer 1

maybe something like:

IF NOT EXISTS ( select * 
                  from sys.objects 
                 where parent_object_id = object_id('MyTable') 
                   and type = 'PK' )

do <create index for rec_index>
