Oracle's function created via jdbc is in an invalid state

Question

When I create Oracle's function in SQL Developer everything is ok, but when I create the same function via jdbc it is in invalid state

Here is the function sample:

create or replace function TEST_FUNC return number is
begin
    return 100;
end;

Java code:

Connection con = ...;
Statement stmt = con.createStatement();
stmt.execute(sql);

When I execute function:

select TEST_FUNC() from dual;

I get error: ORA-06575: Package or function TEST_FUNC is in an invalid state

Can you explain what I'm doing wrong?

Answer 1

Function needed to be complied to use them. Not compiled function gives this exception. Also make sure you do not have any terminating CR/LF in your query. Copy it to a text editor (textpad) to see if you have any.
