ORA-01001: invalid cursor

ORA-01001: invalid cursor

Oracle SQL Error: ORA-01001: invalid cursor

Cause:

Either a host language program call specified an invalid cursor or the value of the MAXOPENCURSORS option in the precompiler command were too small. All cursors must be opened using the OPEN call before being referenced in any of the following calls: SQL, DESCRIBE, NAME, DEFINE, BIND, EXEC, FETCH, and CLOSE.

Solution:

Check the error call statement. Specify a correct LDA area or open the cursor as required. If there is no problem with the cursor, it may be necessary to increase the MAXOPENCURSORS option value before precompiling.

Example:

DECLARE
	CURSOR c1 IS SELECT * FROM books;
	rec books%ROWTYPE;
BEGIN
	LOOP
	FETCH c1 INTO rec;
	EXIT WHEN c1%NOTFOUND;
	DBMS_OUTPUT.PUT_LINE(rec.NAME);
	END LOOP;
END;

Output:

ORA-01001: invalid cursor
ORA-06512: at line 6

Correct

DECLARE
	CURSOR c1 IS SELECT * FROM books;
	rec books%ROWTYPE;
BEGIN
	OPEN c1;
	LOOP
	FETCH c1 INTO rec;
	EXIT WHEN c1%NOTFOUND;
	DBMS_OUTPUT.PUT_LINE(rec.NAME);
	END LOOP;
	CLOSE c1;
END;

Output:

anonymous block completed
