And another demand, please:

Could you - or someone else - please select any JobId and execute the
following (my)sql-statement:

mysql>EXPLAIN SELECT Path.Path, Filename.Name, File.FileIndex,
File.JobId, File.LStat
FROM (
        SELECT max(FileId) as FileId, PathId, FilenameId
        FROM (
                SELECT FileId, PathId, FilenameId
                FROM File
                WHERE JobId IN (<insert your JobId here>)
        ) AS F GROUP BY PathId, FilenameId
) AS Temp JOIN Filename ON (Filename.FilenameId = Temp.FilenameId) JOIN
Path ON (Path.PathId = Temp.PathId) JOIN File ON (File.FileId =
Temp.FileId) WHERE File.FileIndex > 0 ORDER BY JobId, FileIndex ASC

Please post the result. Thanks in advance!
