Hi,
Found this blog http://www.saphana.com/community/blogs/blog/2013/04/07/best-practices-for-sap-hana-data-loads
where he says "Avoid using VARCHARs if you don't need them. Fixed width CHAR is better for smaller fields, and INTEGER fields are even better. VARCHARs have a cost, and don't compress as well."
If it is true then why sap has decided to get rid of CHAR data type in the first place?
Regards,
Vijay.
