Cache SQL sorted after sorting

p rd 13 August 2017

I used Cache 2016.

I used the following statement to sort after paging, but suggested an error:

SELECT *
FROM
  (SELECT sslog.userRowid,
          sslog.CreateDate,
          sslog.CreateTime,
          Sslog.SSUSR,
          sslog.Terminal,
          ssuser.Initials,
          ssuser.USName
   FROM SUser_Log sslog
   LEFT JOIN DHC_SSuser ssuser ON (Sslog.SSUSR = ssuser.userRowid
                                   OR sslog.ssusr = ssuser.Initials
                                   OR sslog.ssusr = ssuser.USName)
   WHERE ssuser.USName ['admin'
   ORDER BY sslog.CreateDate DESC)
WHERE %VID> 5

Also used the following way:

SELECT sslog.userRowid,
       sslog.CreateDate,
       sslog.CreateTime,
       Sslog.SSUSR,
       sslog.Terminal,
       ssuser.Initials,
       ssuser.USName
FROM SUser_Log sslog
LEFT JOIN DHC_SSuser ssuser ON (Sslog.SSUSR = ssuser.userRowid
                                OR sslog.ssusr = ssuser.Initials
                                OR sslog.ssusr = ssuser.USName)
WHERE ssuser.USName ['admin'
  AND %VID> 5
ORDER BY sslog.CreateDate DESC

But suggested that% VID does not exist.

How can I modify my SQL statement? Thank you!

not a problem of version

A subquery using ORDER requires a TOP clause

Change the query to

SELECT *
FROM
  (SELECT TOP ALL
          sslog.userRowid,
          sslog.CreateDate,
          sslog.CreateTime,
          Sslog.SSUSR,
          sslog.Terminal,
          ssuser.Initials,
          ssuser.USName
   FROM SUser_Log sslog
   LEFT JOIN DHC_SSuser ssuser ON (Sslog.SSUSR = ssuser.userRowid
                                   OR sslog.ssusr = ssuser.Initials
                                   OR sslog.ssusr = ssuser.USName)
   WHERE ssuser.USName ['admin'
   ORDER BY sslog.CreateDate DESC)
WHERE %VID> 5

I fixed formatting in your post a little bit just to look it more clear and prettier.

But noticed WHERE% VID instead of WHERE %VID, and AND% VID instead of AND %VID . And decided that it was an formatter error, which I used, but looks like it was in original SQL as well.

So, can you add error message? For me, the first query should work, while next one will not work, because %VID will not exist.

And which Caché version are you using?

%VID appeared since 2011.1.

Is that actually a table or a view ? it seems that %VID works only on SQL Views
