Re: [postgis-users] Import excel file to postgresql
Hi José, You have to convert the excel file to csv and use the copy command like that: copy table_name from 'C:\Users\TEMP\filename.csv' WITH CSV DELIMITER ';'; You have to create the table before and delete the column names of csv file.

Re: [postgis-users] RE : st_offsetcurve
Thanks Hugues...
In this time the select return the street number, my_single_geom and
my_union_geom.
The my_union_geom are the two parallels right?
I tried to see the result in qgis, adding a new column (the_geom) equal
to the column my_union_geom, and adding a new entry inthe table
geometry_columns. But I can not see the result, qgis does not recognize
as a geometry column.
What would have to do to see the result?
Thanks

Ok, the error comes from the select : try using select a.n_street,
my_union_geom, ST_Parallel(the_geom,-3.0,0,0) my_single_geom
I forgot to add the table reference a.
I think I made another mistake using the over method. It would rather be
something like that :
select n_street, st_union(ST_Parallel(the_geom,3.0,0,0)) over(partition by
n_street) my_union_geom,
ST_Parallel(the_geom,-3.0,0,0)) my_single_geom
from streets
Firts time I read too fast this time I wrote too fast !

Hi,
This error is normal. You can not use a group by clause with an aggregate
function and keep all of single records from your original database. Which one
will you choose to keep for each unique n-street value ?
To do that you can use two different tricks (but your table will have as many
lines as you have unique couple n_street/the_geom):
Using with with a join
With my_union as (

Re: [postgis-users] st_offsetcurve
greate. The funcion works.
I'm doing something like that:
ST_Parallel(the_geom,3.0,0,0)
but give me error:
column streetss.the_geom must appear in the GROUP BY clause or be used
in an aggregate function
anybody know the problem?
thanks

Folks,
Sorry about that. The file:
http://www.spatialdbadvisor.com/file_download/55/PostGIS_Parallel.sql
Did not contain all the required types and functions. One needed also
to access the types and functions for my ST_GetVector function.
I have now included all the required types and related functions in
the above script and replaced it on my site.
I have changed a bit in the code as it didn't handle some situations
as I expected. Hopefully my test cases give good coverage.
My tests, conducted on PostgreSQL 9.1 and PostGIS 2.0 on Windows 7 64

0.5 as offset,2 as roundFactor,
