Java获得输出CallableStatement JDBC

我是java中的新手。我尝试在SQL SERVER中创建存储过程（SP）。的SP是：Java获得输出CallableStatement JDBC

go 
create procedure sp_calculate 
    @value1 int = 0, 
    @value2 int = 0, 
    @sum int OUTPUT, 
    @multiply int OUTPUT 
as 
begin 
    set nocount on 
    set @sum = @value1 + @value2 
    set @multiply = @value1 * @value2 
end

我做traint以下Getting the Return Value from JDBC MSSQL。所以，我这样做是在Java中如下：

public static void main(String[] args) { 
    try (Connection conn = ConnectionUtil.getConnection()) { 
     CallableStatement cst = conn.prepareCall("{ (?, ?) = call sp_calculate (@value1 =?, @value2=?) }"); 

     cst.setInt(3, 4);//try some value 
     cst.setInt(4, 10);//try some value 

     cst.registerOutParameter(1, java.sql.Types.INTEGER); 
     cst.registerOutParameter(2, java.sql.Types.INTEGER); 
     cst.executeUpdate(); 
     int sum = cst.getInt(1); 
     int multiply = cst.getInt(2); 
     System.out.println("sum = " + sum + " - product = " + multiply); 
    } 
    catch (SQLException ex) { 
     Logger.getLogger(StoredProcedured.class.getName()).log(Level.SEVERE, null, ex); 
    } 
}

但结果是"com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near '{'." 任何人都可以告诉我，我创造什么错误？

最后，我的工作它指出：

public static void main(String[] args) { 
    try (Connection conn = ConnectionUtil.getConnection()) { 
     CallableStatement cst = conn.prepareCall("{ call sp_calculate (?,?,?,?) }"); 

     cst.setInt(1, 10);//try some value 
     cst.setInt(2, 4);//try some value 

     cst.registerOutParameter(3, java.sql.Types.INTEGER); 
     cst.registerOutParameter(4, java.sql.Types.INTEGER); 
     cst.executeUpdate(); 
     int sum = cst.getInt(3); 
     int product = cst.getInt(4); 
     System.out.println("sum = " + sum + " - product = " + product); 
    } 
    catch (SQLException ex) { 
     Logger.getLogger(StoredProcedured.class.getName()).log(Level.SEVERE, null, ex); 
    } 
}

尝试调用的程序是这样的：

String callableQuery = "{call sp_calculate(?, ?, ?, ?)}"; 

cst.setInt(1, 1); // IN parameter 
cst.setInt(2, 4); // IN parameter 

cst.registerOutParameter(3, java.sql.Types.INTEGER); // OUT parameter 
cst.registerOutParameter(4, java.sql.Types.INTEGER); // OUT parameter

不，我敢肯定，我让它正确的。我试着用一些存储过程之前工作好吧 – haind

@haind anwer更新，检查出来。 – Sajmon

是的。我这样做。非常感谢你 – haind
