Hello all,
I have a big database in which much information is stored in TEXT type
columns (I did this initially because I did not want to limit the
maximum size of the string to be stored)... but...
.. let's say I choose an upper limit (p.ex. 200) for the string sizes
and I start a fresh database with VARCHAR(200).
What tradeoffs can I expect ? disk usage ? query execution times ?
thx
Joao
