Question

I have this query to select a row from table:-

select identifier, name from content where rawid=
        (select contentid from content where rawid='002cd122-f604-4093-b242-1bd12eafaceb')

I want a query which will select all rows from content such that each row corresponds to a rawid from another table, called rawIdentifiers.
I want to give rawid from this table, rawIdentifiers:-

For example, this query will give me one row:-

select identifier, name from content where rawid=
            (select contentid from content where rawid='00504a25-bc6a-4edd-8c30-cb57e12b7c3d')

this will give other row:

    select identifier, name from content where rawid=
                    (select contentid from content where rawid='002cd122-f604-4093-b242-1bd12eafaceb')

and so on.

I want one query to get all the rows in a table. How can I do that?

Sounds like you want to do a join. You may want to read up on joins so that you can understand what exactly they are doing. I think you want something along the lines of:

select identifier, name 
from content 
inner join rawidentifiers ON content.identifier = rawidentifiers.identifier

I’m not sure of your exact table structure so I’m guessing about the column names.
