I am trying to build a function which check for the schema and table in
database if present then select the table values else create that schema and
table and passing schema and table name as parameters of a function.
CREATE OR REPLACE FUNCTION master.chkbypram(schemaname text,state
text,wallmaterial text,roofmaterial text)
RETURNS SETOF refcursor AS
$BODY$
DECLARE
Resulttable refcursor;
tblinclusion text;
Begin
tblinclusion = 'inclusion'||'_'|| $2 ;
if ( (execute 'SELECT exists(select schema_name FROM
information_schema.schemata WHERE schema_name = '||$1||')')and ( execute
'select exists(select * from information_schema.tables where
table_name='||tblinclusion||')') )
then
OPEN Resulttable FOR execute ' select * from '||$1||'.'||$2 using
schemaname,state;
RETURN NEXT Resulttable;
else
execute 'CREATE SCHEMA '||&1 using schemaname;
tblinclusion = 'inclusion'||'_'|| $2 ;
execute 'create table '||&1||'.'||tblinclusion||' AS
select * from master.population_2 where
statecode = '||$2
|| 'and distinct_key not in
(
select distinct(distinct_key)
from master.population_2
where
(
statecode = '||$2
||'and cast (substr(population_2.hhd_housingcodes, 4) as int ) >= 4
and substr(population_2.hhd_housingcodes, 1,1) in (SELECT code FROM
regexp_split_to_table('||$3||', E',') AS code)
and substr(population_2.hhd_housingcodes, 2,1) in (SELECT code FROM
regexp_split_to_table('||$4||', E',') AS code)
)
or
statecode = '||$2
||'and
(
cast (substr(population_2.hhd_assetcodes, 4,1) as int)=3
or cast (substr(population_2.hhd_assetcodes, 5,1) as int)=1

)
or
statecode = '||$2
||'and
