Dear Group, 
 I have 13 tables with duplication of elements and
14th tables that has all the unique elements of 13
tables. What I do not have in 14th table are columns
that are part of these 13 tables. 
I wanted to male a view with all 14 tables. 
My code looks like this:
CREATE  VIEW affy_annotation AS
SELECT
        affy_unique_probeset.affy_probeset_name,
        fc_probe_set_id,
        fc_aeneChip_array,
        fc_species_scientific_name,
        fc_annotation_date,
        ..........................,
        ..................
FROM
        affy_unique_probeset,
        affy_hc_g110,
        affy_hg_focus,
        affy_********,
        affy_********,
        *************,
WHERE affy_unique_probeset.affy_probeset_name =
fc_Probe_Set_ID;
=>\i /home/...../..../postgres/marray2/view.sql
psql:/home/../temp/postgres/marray2/view.sql:58:
ERROR:  column reference "fc
_probe_set_id" is ambiguous
In my case every table (13 numbers) has 20 columns and
column names are identical. 
In the select statement it is difficult to specify
every table name . column name and do this for 20
times for every chip. 
So could any one let me know how to create a view from
multiple tables.
