kdb splayed table meta error

I have a splayed table which I can select data from just fine.

When I try to view the meta data I get a `sym error. Can anyone suggest reasons why this might happen?

 q)meta tablename
 k){$[(20h>t)|77h<t:@x;`;98h>@. t:!x;`;t]}
 'sym
 .:
 `sym
 q.Q))

Solution

You are getting error because enumerated sym file is missing. Normally Q interpreter looks it into one directory above splayed directory.

For ex: If you give a save command like this:

       q)  t:([]sym:`a`b;id:1 2)

       q) `:/home/test/t/ set .Q.en[`:test] t

It will create directory 't' inside /home/test for splayed table 't' and create enumerated 'sym' file in directory /home/test.

To load this table:

       q)\l /home/test

Other thing is, you can also load enumerated 'sym' file manually like this:

       q)sym:get `:path to sym file

All tables in memory will automatically get mapped to this new list.
