it is very easy.
I am using pgrouting workshop2010 material and find the best route. I do it.
but I also want to select special streets in pgsql and show them in red
color in the browser.
for this I have added a filed in the name of "Status" in the pgsql database
. then for some streets that I want to show them in the browser I set the
Status field to CLOSE:
then I want to show the records which the STATUS of them set to  CLOSE  with
red line in the browser. I mean this query:select * from ways where Status
is CLOSE,
with this command I select the streets taht are CLOSE, then I want to show
them in the browser with red color.
I want to select the records that are CLOSE and bring and show them by
geoext format .
do you understand my mean?
