Can we have HDB table without sym column?

Hi, I’ve created few new table in the RDB, without sym columns, and that working fine.

However, after it archive to HDB, and I just run “select from table where date=xxx” , there is error saying that “folder/sym file” is missing, is that a sym column is mandatory for all HDB?

Your hdb is probably missing the sym file=FD. Is there a sym variable defin= ed? key:sym sym in key. How did you save the tables? If you used .Q.en[:.] kdb probably made the s= ym file in the rdb root not the hdb root. You’d have to use .Q.en[`:hdbroot=] instead. If none of your tables have symbol columns, you could create an empty sym f= ile and try again.

Thanks David, I use .Q.dpft 

Sorry, please ignore, it is just I default to use sym as&nbsp;;<tt>p#field if that is not specified
