How to use jmeter to test an Oracle Stored Procedure with sys_refcursor return type?

问题

I want to test an Oracle Stored Procedure by using jmeter.I have done everything but parameters.

And here is my SQL Query:

declare outinfo varchar2(20); outtable sys_refcursor; begin {call RK_JSCX(?,?)}; end;

The outtable in Oracle is a cursor.And i used resultSet to contain it in java.However,whatever i set in parameter types ,it said invalid type.

Sample Start: 2012-10-25 16:06:41 CST Load time: 0 Latency: 0 Size in bytes: 25 Headers size in bytes: 0 Body size in bytes: 25 Sample Count: 1 Error Count: 1 Response code: null 0 Response message: java.sql.SQLException: Invalid data type: cursor

Response headers: oracle.jdbc.driver.T4CConnection@58ba09

SampleResult fields: ContentType: text/plain DataEncoding: UTF-8

How can fix it? Thanks!

Here is my code in java:

public String RK_JSCX() throws Exception {

    RK_JSCX_Response response = null;
    List<RK_JSCX_Outtable> list = null;
    Connection con = null;
    CallableStatement cs = null;
    ResultSet rs = null;
    String sql = null; 
    try {
        sql = "{call RK_JSCX(?,?)}";
        con = ConnectionUtils.getInstance().getConnect();

        if (con.isClosed()) {
            throw new IllegalStateException("ERROR.THE   CONNECTION   ISCLOSED");
        }

        cs = con.prepareCall(sql);
        cs.registerOutParameter(1, oracle.jdbc.OracleTypes.CURSOR);
        cs.registerOutParameter(2, Types.VARCHAR);

        cs.execute();

        rs = (ResultSet) cs.getObject(1);
        list = new ArrayList<RK_JSCX_Outtable>();
        while (rs.next()) {

            RK_JSCX_Outtable out = new RK_JSCX_Outtable(rs.getString(1), rs.getString(2), rs.getString(3), rs.getString(4), rs.getInt(5), rs.getString(6));

            list.add(out);
        }
        String outInfo = cs.getString(2);
        response = new RK_JSCX_Response(list, outInfo);

    } catch (SQLException e) {

        e.printStackTrace();

    } catch (Exception e) {
        e.printStackTrace();

    }finally {

        try {
            if (rs != null) {
                rs.close();
                if (cs != null) {
                    cs.close();
                }
                if (con != null) {
                    con.close();
                }
            }
        } catch (SQLException e) {

            System.out.println("Exception2");
            e.printStackTrace();
        }
    }
    return JSON.toJSONString(response);
}

回答1:

This is how to do it:

SQL Query : call RK_JSCX(?,?)
Parameter values : OUT, OUT
Parameter types : OUT -10,OUT VARCHAR

-10 being the int value of OracleTypes.CURSOR
Variable names: cursor, outInfo
```
 Names are what you want
```

JMeter allows using more types than java.sql.Types constants, in this case instead of using Constant names, you use integer values of constants.

Documentation has been clarified (in next JMeter version) , see:

https://issues.apache.org/bugzilla/show_bug.cgi?id=54048

回答2:

Try with the following changes

change the syntax in calling the procedure to

cs = con.prepareCall("BEGIN RK_JSCX(?, ?); END;");

And I believe your first OUT parameter is VARCHAR2 right? so

cs.registerOutParameter(1, Types.VARCHAR);

then use the following to cast CallableStatement

rs = ((OracleCallableStatement)cs).getCursor(2);

Update 1

I have changed your procedure to demonstrate working version

Procedure

CREATE OR REPLACE PROCEDURE rk_jscx (outtable   OUT sys_refcursor,
                                                 outinfo    OUT VARCHAR2
                                                )
AS
BEGIN
    OPEN outtable FOR
        SELECT  SYSDATE
          FROM  DUAL;

    outinfo := 1;
EXCEPTION
    WHEN NO_DATA_FOUND
    THEN
        outinfo := 2;
        ROLLBACK;
END rk_jscx;

Java Code

CallableStatement stmt = conn.prepareCall("BEGIN rk_jscx(?, ?); END;");
 stmt.registerOutParameter(1, OracleTypes.CURSOR); 
 stmt.registerOutParameter(2, Types.VARCHAR);
 stmt.execute();
      ResultSet rs = ((OracleCallableStatement)stmt).getCursor(1);
      while (rs.next()) {
        System.out.println(rs.getDate("sysdate")); 
      }

The above prints 2012-10-23

Check your jdbc driver as well
