Uniqueidentifier equivalent in Oracle
Posted on 2004-04-26
I may need to migrate an existing SQL Server database to Oracle. The database makes heavy use of the uniqueidentifier data type for primary keys. I read from an older post that there is not a uniqueidentifier equivalent in Oracle. Is this still true? If so, is there any indication this data type may be available in a future version?
I am assuming at this point that I will need to use the char or varchar2 data type to represent this column since I have to synchronize data from the SQL Server system to the Oracle system. Besides the extremely large indexes this will create, do you see any problems with doing this?
If you have any other approaches to this problem, I would love to hear from you.
