在S2SH中调用返回参数的存储过程
在SqlServer中创建存储过程:
create proc test
@result int output ---输出参数
as
begin
declare @test varchar(50)
declare @count int
select @test='this is test proc result:'
select @count = count(*) from GOODSCODE
set @result=@count
print @test
print @count
end
其实,Hibernate中还没发现,其集成处理存储过程的方法,但是可通过Session获得对数据库的连接,走Java调用存储过程的路线
service代码如下:
public List sqlQuery() {
Connection connection = null;
CallableStatement statement = null;
ResultSet rs = null;
connection=factory.getCurrentSession().connection();
try {
statement = connection.prepareCall("{Call test(?)}");
statement.registerOutParameter(1, java.sql.Types.INTEGER);
statement.execute();
System.out.println(statement.getInt(1));
} catch (SQLException e) {
e.printStackTrace();
}
return null;
}
百流积聚,江河是也;文若化风,可以砾石。
