Join two select queries












2















I am trying to join two select queries. Here is my query.



(select 'stack' as id from RDB$DATABASE) t
inner join
(select 'stack' as id from RDB$DATABASE) q
on t.id=q.id


When I execute this query throws me error



Context: Statement::Prepare( (select 'stack' as id from RDB$DATABASE) t
inner join
(select 'stack' as id from RDB$DATABASE) q
on t.id=q.id )
Message: isc_dsql_prepare failed
SQL Message : -104
Invalid token
Engine Code : 335544569
Engine Message :
Dynamic SQL Error
SQL error code = -104
Token unknown - line 1, column 1
(


If I understand the error correctly, Firebird doesn't like '(' at the start of the query.



If so, how can I join two queries?

          The error "Token unknown - line 1, column 1 (" is returned because the presence of ( in that location is unexpected. Your current query only has two sub-queries it is trying to join, but it is missing the select and from clauses. This makes it a syntactically invalid statement. See SELECT in the Firebird 2.5 Language Reference for the full syntax.



          A valid query would be



          select *
          from (select 'stack' as id from RDB$DATABASE) t
          inner join (select 'stack' as id from RDB$DATABASE) q
          on t.id=q.id
