G'day Brent, I'm forever creating tables as subsets of existing tables so it is a truly useful function, however, I've suffered the same concerns - perhaps it is worth pursuing the name being changed?
I've also never really understood the distinction between the populate_ and the probe_ functions? the probe_ one appears to be a 'lite' version, but it may have some other purpose that I don't understand? cheers Ben On 19/05/2011, at 9:02 AM, pcr...@pcreso.com wrote: > I foubd this an unfortunately ambiguous name. > > it doesn't populate geometry columns so much as update the geometry_columns > table. > > But irrespective of the name, it is nice to have :-) > > > Cheers > > Brent Wood > > --- On Thu, 5/19/11, Ben Madin <li...@remoteinformation.com.au> wrote: > > From: Ben Madin <li...@remoteinformation.com.au> > Subject: Re: [postgis-users] how to keep geometry_columns in sync with tables > and views > To: "PostGIS Users Discussion" <postgis-users@postgis.refractions.net> > Date: Thursday, May 19, 2011, 12:50 PM > > Ge, > > Try > > SELECT Populate_Geometry_Columns(); > > http://postgis.refractions.net/docs/Populate_Geometry_Columns.html > > which promises to truncate the geometry columns table first, then rebuild it. > > cheers > > Ben > > > > On 18/05/2011, at 8:05 PM, G. van Es wrote: > >> Hi Edward, >> >> This will not work because this function doesn't do anything with views. >> Also stale records aren't removed. >> >> Ge >> >> --- On Wed, 5/18/11, Edward Mac Gillavry <emacgilla...@hotmail.com> wrote: >> >> From: Edward Mac Gillavry <emacgilla...@hotmail.com> >> Subject: Re: [postgis-users] how to keep geometry_columns in sync with >> tables and views >> To: postgis-users@postgis.refractions.net >> Date: Wednesday, May 18, 2011, 4:57 AM >> >> Hi Ge, >> >> You may want to check Probe_Geometry_Columns >> (http://postgis.refractions.net/docs/Probe_Geometry_Columns.html). >> >> Kind regards, >> >> Edward >> >> >> >> Date: Wed, 18 May 2011 04:38:51 -0700 >> From: gves2...@yahoo.com >> To: postgis-users@postgis.refractions.net >> Subject: [postgis-users] how to keep geometry_columns in sync with tables >> and views >> >> Hi All, >> >> We have a lot of tables and views updated, or better said, replaced on a >> daily basis.
