Merge 2 integer columns into 1 seperate column in database

P: 5
1st column: block_number
2nd column: unit_number

I want to merge the 2 columns and get a tenant_id column.
E.g. block_number = 12
unit_number = 1234

tenant_id = 121234
But i kept trying and get an addition of both columns which is 1246. How should i separate both of them but remain them as int instead of changing them to varchar.

Don't merge them. Keep them separate. You can just calculate it when needed. To do the calculation, use the append operator and not the addition operator.

What I'm trying to say is that you don't need a tenant id column. It repeats data unnecessarily.

I understand. But im trying to say i need this column. It is a compulsory column.

Whether or not it's compulsory, I've already answered the question in my first post.
