Joe, that is exactly what I want.
Could you please give more detail example for this crosstab ? I have
warehouse and product table like this :
CREATE TABLE tblwarehouse (
id integer NOT NULL,
warehousename character varying(20)
);
COPY tblwarehouse (id, warehousename) FROM stdin;
2 OFFICE
3 STORE2
\.
CREATE TABLE tblproduct (
id serial NOT NULL,
produkid text,
warehouseid integer,
onhand integer
);
COPY tblproduct (produkid, warehouseid, onhand) FROM stdin;
2791404000014 2 10
2791404000021 3 10
2791404000014 3 45
\.
I need crosstab query to display record from tblproduct like this :
PRODUKID | OFFICE | STORE2 | TOTAL
---------------+--------+--------+ ------
2791404000014 | 10 | 45 | 55
2791404000021 | 0 | 10 | 10
The crosstab warehouse column name is taken from tblwarehouse so when end
user add warehouse, crosstab column name will change automatically. And also
each row has total qty.
Please give detail command for this.
Thanks in advance !

If I understand your question, the best thing is to run the query
"select distinct warehousename from test order by 1" in your
application first, and then use the result to build a crosstab SQL
string. Then execute the crosstab SQL string with a second query.
