> translate(string|char|varchar input, string|char|varchar from, 
> string|char|varchar to): string
> Translates the input string by replacing the characters present in the from 
> string with the corresponding characters in the to string. This is similar to 
> the translate function in PostgreSQL. If any of the parameters to this UDF 
> are NULL, the result is NULL as well.
