[postgis-users] Using CASE

Hi

I've been attempting to use CASE to establish the spatial point in the following expression.

Update p_id.image
 set the_geom =  
 (select st_translate(library.dgm_device.the_geom, 
 st_x (st_centroid(p_id.p_id.othe_geom))  - 
 st_x (st_centroid(library.dgm_device.ithe_geom)) , 
 st_y (st_centroid(p_id.p_id.othe_geom)) - Select Case when p_id.devices.status = 'Pump #1'
 and p_id.devices.devices_id = '3614'
 then - 10000 - 
 st_y (st_centroid(library.dgm_device.the_geom)))
 from p_id.p_id, library.dgm_device, p_id.processes, processes_count, p_id.devices  
 where library.dgm_device.description = 'In Line Pump'
 and library.dgm_device.orientation = ta_orientation
 and p_id.p_id.p_id_id = processes_count.p_id_id
 and p_id.p_id.process_id = p_id.processes.process_id
 and p_id.devices.devices_id = '3614'
 and  p_id.processes.fluid_id = p_id.devices.fluid_id) 
 from p_id.devices
 where p_id.image.fluid_id = p_id.devices.fluid_id
 and p_id.devices.devices_id = '3614'
 and p_id.image.text_ = 'Pump #1'
 and p_id.image.device_id = '3614';

I get - "ERROR:  syntax error at or near "Select"
LINE 14:  st_y (st_centroid(p_id.p_id.othe_geom)"

Any help would be appreciated.

Bob
