<p class="MsoNormal">I have been able to derive a geometry from a query. I want to insert that geometry into a Multilinestring field. I have some SQL code to do it. When I run the code, the output say that the query was successful. But I don’t see the geometry
inserted into the table. Here is the code:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">update highschools_aroo set routegeom = <o:p></o:p></p>
