Very long object ID's?

[#1]

I created some new tables in one of my files this afternoon, I noticed the Object ID was very long, as in:

CH38_5462303, or LB20_2358345

Why has the underscore and trailing digits been added? I'm used to seeing only integers after the object type, eg. CH24, LB01, etc.

Hi,

You can use in script this condition,

Purgechar(Object ID, '_' & chr(39))   as  Object_ID
