Sql server newsequentialid error validating the default for column

But this is going to be very disruptive (blocking, I/O) if your table is large, since all of the other users on the system will have to wait for that to complete.If you want to see exactly what Management Studio does, create this table: Now, in Object Explorer, right-click the table and choose Design.A computed column is a virtual column that is not physically stored in the table, unless the column is marked PERSISTED.The column is computed from an expression that uses other columns in the same table.An expression that is nullable can be turned into a nonnullable one by specifying ISNULL with the constant, where the constant is a nonnull value substituted for any NULL result.REFERENCES permission on the type is required for computed columns based on common language runtime (CLR) user-defined type expressions.- and you shouldn't be doing that, you should be listing the column names explicitly (and you can then put the columns in any order you want).You can drop and re-create the table, like others have said, with the columns in your preferred order.

Tmp_flarb ( a int NOT NULL, b int NOT NULL, d datetime NOT NULL, c timestamp NOT NULL, e uniqueidentifier NOT NULL ) ON [PRIMARY] GO ALTER TABLE dbo.

Tmp_foo ( a int NULL, b int NULL, r int NULL ) ON [PRIMARY] GO ALTER TABLE dbo.


For example, a computed column can have the definition: cost AS price * qty.

The expression can be a noncomputed column name, constant, function, variable, and any combination of these connected by one or more operators.
