The information in this article applies to:
This article was previously published under Q168659
BUG #: 15660 (NT: 6.5)
SYMPTOMS
In SQL Server 6.5, you will receive a message 1505 when duplicate values
exist in a column and you attempt to create a unique index on that column.
In versions of SQL Server 6.5 earlier than Service Pack 3, the message was
a bit confusing:
Msg. 1505, Level 16, State 1
Create unique index aborted on duplicate key. Primary key is 'type 3c,
len 8'
However, beginning in SQL Server 6.5 Service Pack 3, SQL Server indicates
the duplicate value that the CREATE INDEX command aborted on:
Msg 1505, Level 16, State 1
Create unique index aborted on duplicate key. Primary key is '12'
RESOLUTION
Identify the duplicate column values that make up the index and remove them
before issuing the CREATE UNIQUE NONCLUSTERED INDEX statement.
STATUS
Microsoft has confirmed this to be a problem in SQL Server version 6.5.
This problem has been fixed in Service Pack 3 for Microsoft SQL Server
version 6.5.
MORE INFORMATION
For more information, see the CREATE INDEX statement in the T-SQL Reference
Manual or the SQL Server Books Online.
