当我运行此代码时,我在线程" main"中看到了一个异常。 java.sql.SQLException:参数索引1超出范围(1,0),为什么?
此程序返回:

您需要在调用String中指定参数:
CallableStatement proc = connection.prepareCall("{ call LCD_GetDispInfoAllTimeTable(?) }");
请注意?
,它表示有一个参数需要设置。现在它知道有一个参数可以设置,就像Java或其他语言中的方法一样。如果您想使用多个参数,可以编写多个?
,例如:...LCD_GetDispInfoAllTimeTable(?, ?, ?)
。
答案 1 :(得分:0)
就您的程序声明而言,其代码为:
CREATE DEFINER=`root`@`%` PROCEDURE `LCD_GetDispInfoAllTimeTable`()
BEGIN
SELECT bs.name as bsName, tt.busstoptype as bsType, tt.time as ttTime,
bs.longitude as lon, bs.latitude as lat, tt.timetable_id as ttID,
Bus_Stop
其中过程定义不包含任何参数定义, 所以setParameter或registerOutParameter,不能应用于此程序
