JSP中调用存储过程

数据库：

prepareCall(String sql); 功能：获得CallableStatement对象

sql表示调用存储过程的语句：其调用格式为：{call 存储过程名(?,?,?)}

if exists (select * from sysobjects where name = 'proc_test_selectAll')
drop proc proc_test_selectAll
go
create proc proc_test_selectAll
as
select * from test
go
if exists (select * from sysobjects where name = 'proc_test_add')
drop proc proc_test_add
go
create proc proc_test_add
@name varchar(10),
@sex varchar(2),
@age int
as
insert into test values(@name,@sex,@age)
go
