Hi,

I want to write a update query by considering two table. In my case i want to change the password of a particular person by considering his email id. Means personPassword is one field in person table. And personEmail is another field in another table. My query is :

SQL

UPDATE Person
SET personPassword = @NewOrganizerPassword
Where personEmailID = @PersonEmailID

The two tables are :

1) Person :

PersonID
PersonPassword

2) Person_Email :

PersonID
PersonEmail

How to write the update query for updating the person password.

Thanks in advance......

Solution 1

Try this:

SQL

UPDATE Person
SET Password = @Password
FROM Person p
INNER JOIN Person_Mail
ON p.Personid = Person_Mail.Personid
WHERE PersonMailID = @PersonMailID

Where PersonID =(select  PersonID from Person_Email  where personEmailID=@personEmailID)
