sql server - Create a unique identifier using SQL -

-

is there sql coding can generate unique identifier on click of default button? i'm looking system number physical paper files before placed storage. problem there 3 offices, , each office needs sequential number system (i.e. p001, p002, p003 , c001, c002...).

below code have far generate prefix unique id number.

select case when ptbranch=3 'p' when ptbranch=4 'a' else 'c' end + convert(varchar(2),getdate(),12) lamatter ptmatter = $matter$

the idea code generate whole file number e.g. p110001, p110002 (where p, c or denotes office file in, , 11 denotes year file placed storage)

any pointers appreciated

the sql server function newid() generate guid.

your sql queries not generate buttons or else. sql language querying databases, not writing software interfaces.
