postgis layer query

[Delfos, Jacob]

Hi Christina,
 
Have you checked the tolerance and toleranceunits of the layer? For
example, if you set tolerance to 4, and your units are degrees (rather
than pixels), it would apply about 400km, which would be a lot. Then it
may end up returning everything in your map. So maybe set toleranceunits
to pixels, and the amount to something sensible, and try again.
 
Hope this helps,
 
Jacob

	Hallo all,
	
	I am trying to do a query an Postgis Layer.
	
	In my Postgis Layer there is a tablespace with more than 1000
rows. Every row is a line on my map.
	When I click on a line, I get all the lines in the tablespace
queried. 
	Is it possible, to get only the line queried where I clicked on,
and not the whole tablespace?
	
	I am using Mapscript.
	
	I hope, somebody can help me!
	
	Thanks in advance.
	
	
	Best regards!
