Hi there;<br />
<br />
I got a table having columns having 2 PKs.<br />
<br />
So that is it possible to have same values for a column for the given row?<br />
<br />
Table<br />
ColA ColB<br />
1 &nbsp; &nbsp; &nbsp; &nbsp;2<br />
2 &nbsp; &nbsp; &nbsp; &nbsp;3<br />
3 &nbsp; &nbsp; &nbsp; &nbsp;2<br />
4 &nbsp; &nbsp; &nbsp; &nbsp;4<br />
4 &nbsp; &nbsp; &nbsp; &nbsp;5<br />

For ColA; 4 4 and 4 5, so ColA can have 4, even he is a PK?<br />
Same for ColB 1 2 and 3 2 ?<br />

Kind regards<br />
