Question

I want to copy the CV column with the varbinary info from the table TBLPERSON to the TBLPERSONREPRESENTATION table into the CV column, where the row has the same PersonID as the TBLPERSON. What’s the best way to do this?

TBLPERSON

PersonID | Name   |  CV

1_ _ _ _ | Jo _ _ | **varbinary**
2_ _ _ _ | Cash _ | **varbinary**
3_ _ _ _ | Blade _| **varbinary**

TBLPERSONREPRESENTATION

PersonRepresentationID    | PersonID   | Name  | CV
1 _ _ _ _ _ _ _ _ _ _ _ _ | 1 _ _ _ _ _| Jo    | NULL
2 _ _ _ _ _ _ _ _ _ _ _ _ | 2 _ _ _ _ _| Cash  | NULL
3 _ _ _ _ _ _ _ _ _ _ _ _ | 3 _ _ _ _ _| Blade | NULL

So to be clear I want to copy the varbinary to the CV column in TBLPERSONREPRESENTATION…

Answer 1

This should work:

UPDATE TBLPERSONREPRESENTATION
SET CV = P.CV
FROM TBLPERSON P INNER JOIN
     TBLPERSONREPRESENTATION R ON P.PersonID = R.PersonID
;
