If you actually allocate space in the table, then it's not a proper 'calculated column', though the value in the field might be calculated. A calculated column is a one that only comes into being during a query, when you name the result of some calculation with an AS clause, such as SELECT count(*) AS number_in_the_db FROM tablename....

So, simply allocate the space during CREATE TABLE and structure your UPDATEs and INSERTs such that you do SET tst_Name="some name", tst_NameLength="9" etc.

I don't know why you'd want to save the string length, though.
