triggers

问题 I am using an INSTEAD OF insert trigger on a table to set an incrementing version number on the row and also copy the row to a 2nd history/audit table. The rows are inserted to both tables without a problem. However, I am having trouble returning the new identity from the 1st table back to the user.

Clicking the image should do the same as clicking the link though, I made a JSFiddle to show what I mean (and to show the problem): the JSFiddle When I click the two links in there a new window is opened which has the site I want.
