    The byte size of a field generally depends upon the datatype of the column which you can find out with
    SHOW COLUMNS FROM tbl_tablename;
    1 byte: TINYINT, YEAR
    2 bytes: SMALLINT
    3 bytes: MEDIUMINT, TIME, DATE
    4 bytes: INT, TIMESTAMP,FLOAT etc.
    string types are one byte per character plus one byte for the terminator (unless it's a multibyte character set).
    SELECT LENGTH (string);
    returns the number of characters.
