    Default Concatenation of numbers

    Hello,
    I have a problem of concatenating alphabet.
    I initially gave alphabets numeric value (e.g a=10, b=11) accordingly.
    Now i want to concatenate these vales. I have kept all these values
    in the database, what can i do to make use of the MySQL database to
    bring the values out and use them for concatenation in order to form
    a word.

    Concatenation of a word like "baby" (11+10+11+35) brings 11101135.
    How do i do it?

    Thank you very much

    The compiler thinks 10+2 is a numeric expression and will add the two number together.
    If you want to create a String with "10" and "2" put an empty String: "" between them:
    10 + "" + 2
