I have a function that takes as a parameter ROWTYPE:
create or replace function test_func(test_table)
returns varchar as '
declare
lv_return varchar;
begin
......
return lv_return;
end;
' LANGUAGE 'plpgsql';
How do I call this function from the C program (ecpg)? How my
declaration should look like?
I trued structure and got error: Too many arguments
Thanks for your help
