Conversion of 'Date' field using UDF

Hi Experts,

Please help me to get a clear view on the below matter:

>can we write a 'UDF' to convert a date format of SAP(YYYYMMDD) into a particular standard date format(e.g JDBC:ddmonyy)?if yes,please share the template of the UDF? (or without UDF,any other way is there?)

Regards,

Rasmiraj Tripathy.
