beginner:problem in Dynamic query with postGIS

[Win Myint Aung]

Dear members,

I would like request you to help me the dynamic query problems. I created map file to show the point for one day on map. Because the table in PostGIS has many rows for many different days. I tested with FILTER but it is not the one I want. I tried to make criteria in DATA by WHERE clause. Please see map file here.

This part make errors in map file. Other part is ok.

LAYER #Confidence
  CONNECTIONTYPE postgis
  NAME "firepoint"
  CONNECTION "user=postgres password=kyawsannoo1234 dbname=hotspot_db host=localhost port=5432"
#  DATA "the_geom from firepoint"
  DATA "the_geom FROM (SELECT hotspot_tmp.the_geom as the_geom,hotspot_tmp.gid as oid,hotspot_tmp.date as date 
 FROM hotspot_tmp WHERE hotspot_tmp.date='2006-08-15')"
#  FILTER "f_posibl >=75"
#  HEADER '/ms4w/projects/hotspot/htdocs/templates/HFVS_header.html'
#  FOOTER '/ms4w/projects/hotspot/htdocs/templates/HFVS_footer.html'

msDrawMap(): Image handling error. Failed to draw layer named 'firepoint'. 
prepare_database(): Query error. Error executing POSTGIS DECLARE (the actual query) statement: 'DECLARE mycursor BINARY CURSOR FOR SELECT f_posibl::text,asbinary(force_collection(force_2d(the_geom)),'NDR'),OID::text from (SELECT hotspot_tmp.the_geom as the_geom,hotspot_tmp.gid as oid,hotspot_tmp.date as date FROM hotspot_tmp WHERE hotspot_tmp.date='2006-08-15') WHERE the_geom && setSRID('BOX3D(-15 -80,195 60)'::BOX3D, find_srid('','(SELECT hotspot_tmp.the_geom as the_geom,hotspot_tmp.gid as oid,hotspot_tmp.date as date FROM hotspot_tmp WHERE hotspot_tmp.date='2006-08-15')','the_geom') )' 

Postgresql reports the error as 'ERROR: subquery in FROM must have an alias HINT: For example, FROM (SELECT ...) [AS] foo. '

More Help:

Error with POSTGIS data variable. You specified '<check your .map file>'.
Standard ways of specifiying are : 
(1) 'geometry_column from geometry_table' 
(2) 'geometry_column from (<sub query>) as foo using unique <column name> using SRID=<srid#>' 

Make sure you put in the 'using unique <column name>' and 'using SRID=#' clauses in.
