SQL & PL/SQL :: Parsing Name And Address?

I intend to write procedures/functions in PL/SQL to parse Name

field into various fields : Title, FirstName, MiddleName, LastName, Gender
E.g:
Nguyen Van A
Nguyen Thi B

After parsing, the result will be shown as:

TitleFirstNameMiddleNameLastNameGender
MrNguyenVanAMale
MsNguyenThiBFemale

I supposed that Title & Gender are realized through MiddleName field. If MiddleName's values in (Thi, Dieu) then Title is assigned as Ms, and Gender =

Female. Otherwise, Title = "Mr", and Gender = "Male".

2/ Another procedure/function is ParseAddress with the

requirement as:

Address field is divided into Street, Group, Area, Ward, County fields
E.g.:
No 6 Sum Street - Group 8 - Area 2 - ABCD Ward - London

The result:

StreetGroupAreaWardCounty No 6 Sum StreetGroup 8Area 2ABCDLondon

I have tried coding by Visual Basic, it is OK. But if I interpret to PL/SQL ->

it doesn't work.
