stored procedure is not displaying results in jsp

问题

I am trying to execute results from my stored procedure and it is not displaying anything. I have played around with sql syntax query and nothing worked...when I do a normal select statement I get results from my tables, but so far nothing worked with my stored procedure...what am I not getting results ?

I am using sql-server by the way

   <%        
    Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
    String url = "jdbc:sqlserver://....";
    String username = "something";
     String password = "something";

    Connection conn = DriverManager.getConnection(url, username, password);
    Statement stmt = conn.createStatement();
    ResultSet rs;
    CallableStatement cs;

    cs = conn.prepareCall("{ exec rptGetAssetbyLocation(?, ?,?,?,?,?) }");


    cs.setString(1, "name");
    cs.setString(2, "model");
    cs.setString(3, "serialNumber");

    cs.setString(4, "type");
    cs.setString(5, "condition");
    cs.setString(6, "note");

    try {
    cs.execute();
    out.println("Stored procedure completed successfully.<br>");
    } catch (Exception e) {
    out.println("The following error occurred: " + e + "<br>");
    }

    %>

edit:

ran a stacktrace

I am getting an error com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near '{'.

回答1:

To display the output from the procedure to need to do something like this

char val= ((OracleCallableStatement)cs).getCHAR(3)

Remember OracleCallableStatement is an interface which implements CallableStatement, OraclePreparedStatement

You can override its method to get the results from the callable statments

Also these examples would help you
