IBatis.Net学习笔记(七):在IBatis.Net中调用存储过程
其实调用方式比较简单,主要也就是两种类型的存储过程:
1、更新类型的存储过程
2、查询类型的存储过程
下面就来看看具体的调用方式:
1、更新类型的存储过程
sp_InsertAccount:
CREATE PROCEDURE [dbo].[sp_InsertAccount]
-- Add the parameters for the stored procedure here
@Account_ID int,
@Account_FirstName varchar(32),
@Account_LastName varchar(32)AS
BEGIN
insert into accounts (account_id, account_firstname, account_lastname)
values (@Account_ID,@Account_FirstName,@Account_LastName )
END
Map配置文件:-- Add the parameters for the stored procedure here
@Account_ID int,
@Account_FirstName varchar(32),
@Account_LastName varchar(32)AS
BEGIN
insert into accounts (account_id, account_firstname, account_lastname)
values (@Account_ID,@Account_FirstName,@Account_LastName )
END
<procedure id="InsertAccountViaStoreProcedure" parameterMap="insert-params_new">
sp_InsertAccount
</procedure>
<parameterMap id="insert-params_new" class="Account">
<parameter property="Id" />
<parameter property="FirstName" />
<parameter property="LastName" />
</parameterMap>
sp_InsertAccount
</procedure>
<parameterMap id="insert-params_new" class="Account">
<parameter property="Id" />
<parameter property="FirstName" />
<parameter property="LastName" />
</parameterMap>
这里要注意的就是ParameterMap中的参数个数和顺序要和sp_InsertAccount存储过程中的一致
Ado中的调用代码:
public void InsertAccountViaStoreProcedure(Account account)
{
try
{
sqlMap.Insert("InsertAccountViaStoreProcedure", account);
}
catch (DataAccessException ex)
{
throw new DataAccessException("Error executing InsertAccountViaStoreProcedure. Cause :" + ex.Message, ex);
}
}
{
try
{
sqlMap.Insert("InsertAccountViaStoreProcedure", account);
}
catch (DataAccessException ex)
{
throw new DataAccessException("Error executing InsertAccountViaStoreProcedure. Cause :" + ex.Message, ex);
}
}
这里使用的是sqlMap.Insert的方法,为了看起来直观一点,其实使用sqlMap.QueryForObject方法的话效果也是一样的:)
2、查询类型的存储过程
GetAccountByName:
CREATE PROCEDURE [dbo].[GetAccountByName]
@name varchar(32)
AS
BEGIN
select * from accounts where Account_FirstName like '%' + @name + '%'
END
@name varchar(32)
AS
BEGIN
select * from accounts where Account_FirstName like '%' + @name + '%'
END
Map配置文件:
<procedure id="GetAccountByNameViaStoreProcedure" resultMap="account-result" parameterMap="selectpro-params">
GetAccountByName
</procedure>
<parameterMap id="selectpro-params" class="string">
<parameter property="name"/>
</parameterMap>
这里parameterMap也是和上面的要求一样,至于property的名字在这里没有实际作用,可以任意取名的GetAccountByName
</procedure>
<parameterMap id="selectpro-params" class="string">
<parameter property="name"/>
</parameterMap>
Ado中的调用代码:
public ArrayList GetAccountByNameViaStoreProcedure(string strName)
{
try
{
ArrayList list = (ArrayList)sqlMap.QueryForList("GetAccountByNameViaStoreProcedure", strName);
return list;
}
catch (DataAccessException ex)
{
throw new DataAccessException("Error executing SqlAccountViaSqlMapDao.GetAccountById. Cause :" + ex.Message, ex);
}
}
{
try
{
ArrayList list = (ArrayList)sqlMap.QueryForList("GetAccountByNameViaStoreProcedure", strName);
return list;
}
catch (DataAccessException ex)
{
throw new DataAccessException("Error executing SqlAccountViaSqlMapDao.GetAccountById. Cause :" + ex.Message, ex);
}
}
