Hello Monks,

I'm trying to find the best way to represent an SQL query using SQL::Abstract (actually SQL::Abstract::More via DBIx::DataModel; SQL::Abstract is also used by DBIx::Class). Unfortunately there is not a great deal of information on constructing SQL queries that fall outside the bounds of the usual 'SELECT * FROM x WHERE ...' using SQL::Abstract.

My ideal query:

SELECT 
  CASE
    WHEN record.is_public = 'Yes' THEN 'public'
    WHEN EXISTS ( SELECT 1
      FROM permissions
      WHERE permissions.rec_id = record.id AND user_id = $user_id )
      THEN 'accessible'
  ELSE
    'private'
  END
  AS viewable,
 record.id,
 record.display_name
FROM
record
WHERE 
record.id = $rec_id; # or other criteria

[download]

...where $user_id and $rec_id (or other WHERE criteria) are supplied by the Perl code.

Has anyone used SQL::Abstract for this kind of query?

Thanks!
