I have had a read thru the "DB2 for i5/OS porting guide: MySQL to System i
platform" and found a very interesting statement made about when to use
Char versus VarChar. Page 11 has this tidbit:
"The CHAR data type must always be used for columns of 40 bytes or fewer."
Why would IBM make such a strong statement that we use a Char when the
field is less than 40 bytes in length? Would it still be the case when I
have a 35 character field that over 75% of the time only contains 15
characters? What about a 10 character field that is mostly only has data
that is 4 characters in length? I realize that with a VarChar there are
the bytes tacked on to contain the length, but I must be missing something
someplace.
Can someone with some deep dark knowledge of the internal workings of DB2
for i5/OS give me some info on why IBM would say this.
Thanks,
Scott
