1.数据查询功能的不带参数的存储过程

CREATE PROCEDURE Summer_s  
AS  
BEGIN  
SELECT * FROM ES_LOG  WHERE OpTime like ‘%2019%‘
END  
--Summer_s 为存储过程名字 
GO
EXEC Summer_s

 在存储过程中可以包含多个select语句

CREATE PROCEDURE Summer_es  
AS  
BEGIN  
SELECT count (*) FROM ES_Log WHERE OpTime LIKE ‘%2019%‘
SELECT * FROM ES_Log  WHERE OpTime LIKE ‘%2019%‘
END  
--Summer_s 为 存储过程名字 
GO
EXEC Summer_es

2.带有输入参数的数据查询功能的存储过程，使用LIKE 模糊查询

CREATE PROC Summer_like
@para1 nvarchar(50)
AS  
BEGIN  
SELECT count (*) FROM ES_Log WHERE OpTime LIKE  (‘%‘+@para1+‘%‘)
SELECT * FROM ES_Log  WHERE OpTime LIKE (‘%‘+@para1+‘%‘)
END  
--Summer_ like 为 存储过程名字 
GO
EXEC Summer_like 2019
