Given a <codeph>CDbColSet* set</codeph>, we can count the number of nullable columns like this:</p> <codeblock id="GUID-14CED4FF-C2A4-54E4-B089-A97EA9503AE6" xml:space="preserve">TInt nullable=0;
+for (TDbColSetIter iter(*set);iter;++iter)

+        ++nullable;
+    }</codeblock> </section> </conbody></concept>
