写了一个存储过程，在调用存储过程的时候，需要把一个参数传进去怎么写阿 大神
给你看一下我工作中写的存储过程，希望对你有帮助。
DELIMITER $$
DROP PROCEDURE IF EXISTS zp_stat_35001$$
CREATE PROCEDURE zp_stat_35001(IN para1 VARCHAR(512) , IN para2 VARCHAR(512))
BEGIN
if para1 = 1 then
select lastid from stat_configure where cmd=35001;
elseif para1 = 2 then
SELECT 'ALL',f_status as state,f_trade_date as tradedate,unix_timestamp(f_trade_date_start) as starttrade,unix_timestamp(f_status_start) as starttime,unix_timestamp(f_status_end) as endtime,
unix_timestamp(f_trade_date_end) as endtrade, f_last_trade_date as lasttradedate,f_update_time as updatetime FROM t_market_status where f_update_time > para2 order by f_update_time DESC limit 1;
elseif para1 = 3 then
update stat_configure set lastid = para2 where cmd=35001;
end if;
END$$
DELIMITER ;
调用方法：
call zp_stat_35001(2,'2016-10-18 14:24:00')
