在Oracle PL / SQL中调用存储过程

Question

I have written a procedure with a cursor in it in Oracle 11g so that I can use it in Java code. Can anybody tell me how I can use this procedure and call it from Java code?

create or replace
PROCEDURE show_students
(
students_cursor OUT SYS_REFCURSOR
)AS
BEGIN
OPEN students_cursor FOR
SELECT * from students;
END show_students;

Answer 1

use this:

CallableStatement stmt = connection.prepareCall("BEGIN SHOW_STUDENTS(?); END;");
stmt.registerOutParameter(1, OracleTypes.CURSOR); //REF CURSOR
stmt.execute();
rs = ((OracleCallableStatement)stmt).getCursor(1);

I suggest using function in this case instead of procedure.

Notice that I suppose you have the connection to DB as "connection"
