Dear list,
I recently discovered the crosstab function in postgresql.
What I'm trying to accomplish is turn this:
Suppliernumber Productnumber Price
0 2 0.8
0 3 1.2
1 2 0.9
1 3 1.1
Into this:
Productnumber Supplier1 Supplier2
2 0.8 0.9
3 1.2 1.1
The problem is that the data is being shifted when there is no
price for Supplier1 for product 3:
Productnumber Supplier1 Supplier2
2 0.8 0.9
3 1.1(WRONG!)
I'm using this command to retrieve the data:
select * from crosstab('select int_artnr, int_crednr, flt_inkoopprijs from
artcredinkoopprijzen where
int_crednr = 2 OR int_crednr = 3') as c(int_artnr integer, supp1 float4,
supp2
float4);
Am I doing something wrong or is this a limitation of the function?
With kind regards,
Paul
