Question

I’m making this select:

select code,name from talbe1
union all
select code,name from table2

The actual code isnt important to me but what is important to me is that the code column will be unique column, and with this select I cant grantee it..
Is there any save word/something that will give me something like that:

select getUniqueCode(),name from(
select name from talbe1
union all
select name from table2)

Thanks.

Have a look at the mysql UUID call. Which would result in something like this:

select UUID(),name from(
select name from talbe1
union all
select name from table2)
