Get data from PostgreSQL function to java

Question

I have written a simple function in PostgreSQL database. From my JAVA source code I am calling this function like

SELECT getData(\'act         


        

Answer 1

As your function returns a result set you should be using select * from getdata('active').

Don't put calls to set returning functions into the select list.

SELECT usr.username 
FROM cust_invoice_index as inv
 JOIN (SELECT * FROM getdata('active')) as usr ON usr.userid=inv.userid_edit
