一、连接数据库
mysql -uroot -p
输入密码后，
a、使用show databases; 查看数据库。
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| sys |
| test |
| webinfo |
+--------------------+
6 rows in set (0.00 sec)
b、切换数据库 use webinfo;
mysql> use webinfo;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
c、查看表及表结构
show tables;
mysql> show tables;
+--------------------+
| Tables_in_webinfo |
+--------------------+
| spider_event |
| spider_record |
| spider_record_list |
+--------------------+
3 rows in set (0.00 sec)
desc spider_record;
mysql> desc spider_record;
+--------------------+--------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+--------------------+--------------+------+-----+---------+----------------+
| id | int(11) | NO | PRI | NULL | auto_increment |
| starttime | datetime | YES | | NULL | |
| endtime | datetime | YES | | NULL | |
| keyword | varchar(512) | YES | | NULL | |
| result_type | int(11) | YES | | NULL | |
| findcounts | int(11) | YES | | NULL | |
| keyword_findcounts | int(11) | YES | | NULL | |
+--------------------+--------------+------+-----+---------+----------------+
7 rows in set (0.00 sec)
二、创建存储过程
a、CREATE PROCEDURE 存储过程名
delimiter //
CREATE PROCEDURE proc_add_spider_recorda(
IN stime datetime,
IN etime datetime,
IN kword nvarchar(100),
IN rtype INTEGER,
IN fcounts INTEGER,
IN kfcounts INTEGER,
OUT retid int
)
BEGIN
start transaction;
insert into spider_record(starttime,endtime,keyword,result_type,findcounts,keyword_findcounts)
values(stime,etime,kword,rtype,fcounts,kfcounts);
SELECT LAST_INSERT_ID() into retid;
commit;
END
//注意：delimiter // 是定义结束符。mysql 默认的结束符是;号，这里重新定义了结束符为//,否则中间的语句中遇到 ;号，会认为语句已经结束了。所以需要重新定义结束符，否则会报错。END 后面加//，就是代表已经结束。感觉好坑
b、查看存储过程
show produre proc_add_spider_recorda;
三、使用存储过程
SET @retid=-1;#@retid 是 out参数
CALL proc_add_spider_record('2019-01-01 12:00:00','2019-01-01 12:05:00','a',1,0,0,@retid) ;
SELECT @retid;
