Populating A DB From 2 Tables (Dynamic)

Hi

I am quite new to the complexities of MS SQL and have a problem, I would like to resolve. I have 2 tables with a unique identifier in both and want to populate a new table with information from both, but the second table I would like to populate just some fields that have a DOB eg

Table 1:
uniqueId
Name
Address

Table2:
uniqueId
Type
Setting

example of content for Table 2:
uniqueId Type Setting
123 DOB 03/04/74
234 TFN 12345678
567 POA Mr Smith

So the new table needs to be populated with a ll of info in table 1 and has a new field called DOB so only the clients with a DOB should populate this field, if the client in Table 1 has a TFN reference, this record should be added to the new table but no value needs to be entered eg

123 Chris Smith 1 high street 03/04/74
234 Jon brown 2 high terrace <Null>
