Hi there Im a new member of the community I would like to ask a question regarding on how to update a record on the database,

 

for example i have a table 

 

Users

UserID | Lastname| Firstname| password|email address|

1            a                 b              

 

 

is there a way that if i input the lastname firstname password and email address, if the lastname and firstname  exist it will just update the record.

 

Thanks in advance
