Hello.
 
I have a very simple sql-question from an sql-beginner:
 
Suppose I have Table A looking something like this:
 
Index    Text    NrA
 
And Table B like this:
 
NrA    NrB
 
Then I want to change all occurences of NrA in Table A to NrB...
 
I've tried:
 
UPDATE tableA Set tableA.nrA = B.nrB From tableB B Where tableA.nrA = B.nrA;
 
But that doesn't seem to work...
 
Best regards
