guid is the correct solution if you want it globally unique - why does the fact it's a complicated string (it's not a string, that's just how the UI renders it) matter?

you acn use another table to hold on the globel id.

table_globel_id<br />
@id as bigint

whenever inserting to any table use ID from this table
like: select isnull(id,0) from table_globel_id

and whenever complitiong the sql query/transaction increase the value of the id in table_globel_id.

like:

SQL

if exixt(select * from table_globel_id)
 then 
update table_globel_id set id=id+1
else
insert into table_globel_id(id)=1

GUID is the commonly used solution. If you dont like it then try process id with thread id and append timestamp.
