merge hdb

[Isaac]

Hi,

   Is there a way to merge sym files, which are for hdb data.     I have two hdb folders, they are same except the date.

Here is a link http://code.kx.com/wiki/Contrib/CompactingHdbSym to help you get started. It will not solve your problem directly but you will get some ideas from this script.

HTH,

Kim

basically, re-enumerate one by the other's symfile, then you can
manipulate the data as you like

should be something like

\l hdb2
\l dbmaint.q
{fncol'[`:.;x;exec c from meta x where
t="s";`:/path/to/hdb1/sym?get@]}each{x where -1h=(type .Q.qp get@)each
x}tables[]
