I am trying to add PK on exsting table having data.

My script:

1.ALTER TABLE dbo.Posting_Zeroes_post_dates ADD [ID] [INT] PRIMARY KEY IDENTITY (1, 1) NOT NULL

Before running this script I am droping the exsisting index on that table . just giving more details.

2.ALTER TABLE dbo.Posting_Zeroes_post_dates DROP CONSTRAINT IX_Posting_Zeroes_post_dates

I am getting error on 1 sql.
Error :
Msg 1505, Level 16, State 1, Line 1
CREATE UNIQUE INDEX terminated because a duplicate key was found for object name 'dbo.Posting_Zeroes_post_dates' and index name 'PK__Posting_Zeroes_p__20285207'. The duplicate key value is (69).
Msg 1750, Level 16, State 0, Line 1
Could not create constraint. See previous errors.
The statement has been terminated.

I have check and could not find duplicate records.

I am restoring data from Prodcution to Test and ran the above sql , i got above error but if i ran the sql again after half an hour it ran sucessfully.

Any help would be appreciated.

I believe you need to include the Key Name as shown below:

ALTER TABLE dbo.Posting_Zeroes_post_dates ADD [ID] [INT] PRIMARY KEY (IX_Posting_Zeroes_post_dates) IDENTITY (1, 1) NOT NULL

it is the instance name that you gave when installing sql server on your machine.
click on 'Browse for more' under servers and you must see the instance name under local server-database engine
