[postgis-users] GeomFromText in a user function.<BR></FONT><BR></DIV>

<P class=MsoNormal>I’m going to apologize up front for being a
nood.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>I have been trying to create a user function that I can call
as needed by passing in bbox coordinates. I have the standard SQL working as
show below;<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>SELECT *<o:p></o:p></P>
<P class=MsoNormal>FROM "MyTable" t<o:p></o:p></P>
<P class=MsoNormal>WHERE WITHIN(<o:p></o:p></P>
<P class=MsoNormal>GeomFromText('POLYGON((5 1, 8 4, 7 3, 6 2, 5
1))'),t.geom);<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>The above runs fine, they are not valid values based on the
geom column is based on lat/lon.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>When I place it in a PostgreSQL function it keeps telling me
“type "geomfromtext" does not exist”.<o:p></o:p></P>
<P class=MsoNormal>I have run out of ideas and can’t find a lot on the net about
PostgreSQL function similar to this. Below is my last attempt:<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>CREATE OR REPLACE FUNCTION fn_Poly(double precision, double
precision, double precision, double precision, double precision, double
precision, double precision, double precision)<o:p></o:p></P>
