Error validating the default for column newsequentialid


If not, how would I pass those values into a udf and use it for the formula?

Question is not well formed : Although the IDENTITY property automates row numbering within one table, separate tables, each with its own identifier column, can generate the same values.

After some investigation we figured out that we could use the new OS function Uuid Create Sequential with some byte scrambling to convince the rest of SQL engine that guids are produced in sequential order.

I want to create a computed column with this formula: ISNULL(NULLIF (tot_mnc, 0) / NULLIF (repl_value, 0), 0) It works in a straight select query, but when I put it in the formula of the table design window, I get an error "Error validating the formula for column 'test_fci'" I don't know if it's relevant but repl_value is itself a computed column with the formula: (repl_value_e_g + repl_value_aux) Is it possible to use the system functions in a computed column?

When I try and do this I get an error "error validating default value for column".

This is because the IDENTITY property is guaranteed to be unique only for the table on which it is used.

I imagine that by now you already have a solution, but I'm posting for the benefit of the next person to come across it. When a GUID column is used as a row identifier, using NEWSEQUENTIALID can be faster than using the NEWID function.The Database Engine does not automatically generate values for the column.To insert a globally unique value, create a DEFAULT definition on the column that uses the NEWID or NEWSEQUENTIALID function to generate a globally unique value.

Creates a GUID that is greater than any GUID previously generated by this function on a specified computer since Windows was started.After restarting Windows, the GUID can start again from a lower range, but is still globally unique.
