Hi Friends,
I want to know which data type was best to choose for assigning Primary Keys.
If we choose INT as a data type by default it takes 32 bits (4 bytes) in Hana.
For even small values like 2,33,55 also i know that it takes 4 bytes only.
Kindly tell me the advantages & disadvantages of INTEGER over VARCHAR when use a column as a primary key.
Also tell me the advantages & disadvantages of VARCHAR over INTEGER when we assigning VARCHAR as a primary key.
Please Ellaborate
