Question: ORA-01012: not logged on after successful (?) login

I'm trying to write simple program using precompilators. Please help. After connecting do database whatever I try to do (OPEN CURSOR, SELECT...), I got

ORACLE error-- ORA-01012: not logged on

I did it 3 lines before? What am I doing wrong?

EXEC SQL CONNECT :username IDENTIFIED BY :password AT :uuser USING :bazadanych;

    printf("\nConnected to ORACLE as user: %s\n", username);

EXEC SQL DECLARE salespeople CURSOR FOR

        SELECT title
            FROM articles;	

/* Open the cursor. */

           EXEC SQL OPEN salespeople USING :bazadanych;

!!!!!!!!!!!!!!!!!!!!!!

Thanks in advance.
