Hi, Does anyone here know if switching from CHAR to VARCHAR gives any positive effect in terms of table size? Explain the situation briefly. I've got an application written on ILE/C that works with rather big table (historical data since 1996). Currently the table size is 260M records and PF size 170GB. The record size is app. 650 bytes and it has some pretty large char fields, that can be either empty or almost empty :-) Technically I can make a new table with VARCHARs and rewrite my program to use VARCHAR instead of CHAR, but shall it reduce the table size? Somehow I suspect that it will only increase the table... TIA and regards, Jevgeni. -- This is the Bare Metal Programming IBM i (AS/400 and iSeries) (C400-L) mailing list To post a message email: C400-L-Zwy7GipZuJhWk0Htik3J/[email protected] To subscribe, unsubscribe, or change list options, visit: https://lists.midrange.com/mailman/listinfo/c400-l or email: C400-L-request-Zwy7GipZuJhWk0Htik3J/[email protected] Before posting, please take a moment to review the archives at https://archive.midrange.com/c400-l.
