mysql 存储过程用程序调的问题

记一下，存储过程加了commit结果用mysql客户端执行不报错，用jdbcTemplate执行就执行了一步，因为加了commit后面的程序都不跑了。另外

存储过程里面如果用java调的话select赋值也会中断存储过程

#SELECT @v_bill_cycle:=bill_cycle_id FROM T_BILL_CYCLE WHERE DATE_FORMAT(from_time,'%Y%m') = v_year_month;
    
    set @v_bill_cycle = v_year_month;

    set @month_states = (SELECT month_state FROM T_PRODUCT_BILLSTATE_SPEC WHERE bill_state=v_bill_state AND product_spec_id = v_product_spec_id);

　　要注意赋值的时候select加上括号

　

　最后决定还是用jdbc去调用

public void callPBillAttrSync(String yearMonth) {
		jdbcTemplate.execute("CALL P_BILL_SYNC_ALL_ATTR("+yearMonth+")");
	}
	public void callPBillSyncJDBC(String yearMonth) {
		String sql="{CALL P_BILL_SYNC(?)}";
		Connection con = DataSourceUtils.getConnection(dataSource);
		try {
			CallableStatement c=con.prepareCall(sql);
			c.setString(1, yearMonth);
			c.execute();
		} catch (SQLException e) {
			e.printStackTrace();
		}  
	}

　　还是报错了，

好吧，给存储过程加个返回值试下，

public int callMethod(String sql,String yearMonth){
		Connection con = DataSourceUtils.getConnection(dataSource);
		//String flag="@flag";
		try {
			System.out.println(sql+","+yearMonth);
			CallableStatement c=con.prepareCall(sql);
			//if(!yearMonth.equals("0")){
				System.out.println(yearMonth);
				c.setString(1, yearMonth);
				//c.setString(2, flag);
				c.registerOutParameter(2,Types.VARCHAR);
			//}
			c.setQueryTimeout(5);
			try{
				c.execute();
				String rec_cnt=c.getString(2);
				System.out.println(rec_cnt);
			}catch(SQLTimeoutException  e){
				c.close();
				con.close();
				return 0;
			}
			c.close();
			con.close();
			return 0;
		} catch (SQLException e) {
			e.printStackTrace();
			try {
				con.close();
			} catch (SQLException e1) {
				e1.printStackTrace();
			}
			return 0;
		}
	}

　　

 结果调用存储过程的时候报Parameter number 2 is not an OUT parameter ，

一查报错源码发现noAccessToProcedureBodies=false就抛异常了，为什么会抛出这个异常呢？

 好吧，百度了下，找到了这么一条有用的信息https://www.aliyun.com/jiaocheng/1117218.html

解释：这是因为jdbc调用存储过程时需要有show create procudure权限或是有表mysql.proc的select的权限

解决方法: 
1.通过在jdbc连接属性中设置noAccessToProcedureBodies=true(默认是false)。但是加该参数会有影响 
- 调用存储过程时,将没有类型检查,设为字符串类型,并且所有的参数设为in类型,但是在调用registerOutParameter时,不抛出异常 
- 存储过程的查询结果无法使用getXXX(String parameterName)的形式获取,只能通过getXXX(int parameterIndex)的方式获取

想想我们的数据库经过了mycat代理，就选择直连的方式，不用mycat代理（因为直连是用的root账号，这个要改下，并且存储过程也要设置为该用户的所有者）

好的，终于不报错了。坑爹啊，，，，，

存储过程如下：
