.net操作Oracle存贮过程
http://www.microsoft.com/china/MSDN/library/data/dataAccess/DMSDNorsps.mspx?mfr=true
是微软的实例及应用。讲解的不错。不过其中创建的存储过程需要将new换成Repleace。下面是我做的实例。
1 表结构及数据：
1 系统功能 0 1
2 客户中心 1 0
3 潜在客户 2 0
4 现在客户 2 1
5 历史客户 2 1
6 报表中心 1 1
7 总公司报表 6 1
8 中化工报表 7 1
9 基本情况表 8 1
10 主要经济 8 1
11 办公中心 1 1
12 公文流转 11 1
13 日程管理 11 1
2 存贮过程：
CREATE OR REPLACE PROCEDURE InfoManager.COUNT_SysFunction
(
reccount OUT NUMBER
)
IS
BEGIN
SELECT COUNT(*) INTO reccount
FROM Infomanager.Sysfunction;
END COUNT_SysFunction;
3 引用Oracle连接 ：
using System.Data.OracleClient;
4 代码 ：
OracleConnection conn
=
new
OracleConnection(System.Configuration.ConfigurationManager.AppSettings[
"
DBConnStr
"
]); OracleCommand cmd
=
new
OracleCommand(); cmd.Connection
=
conn; cmd.CommandText
=
"
COUNT_SysFunction
"
; cmd.CommandType
=
CommandType.StoredProcedure; cmd.Parameters.Add(
"
reccount
"
, OracleType.Number); cmd.Parameters[
"
reccount
"
].Direction
=
ParameterDirection.Output; conn.Open(); cmd.ExecuteNonQuery(); conn.Close(); Label1.Text
=
cmd.Parameters[
"
reccount
"
].Value.ToString(); conn.Close();
测试通过：
当然还有另外两个例子数据库连接方式参看上面的 工程方式连接数据库(http://tb.blog.csdn.net/TrackBack.aspx?PostId=1539106)，一个用来更新数据库操作，一个用来显示多参数的传递。
CREATE OR REPLACE PROCEDURE InfoManager.UPD_SYSFUNCTION
(
func_id char
)
IS
BEGIN
update infomanager.sysfunction
set 标志 = 0
WHERE 功能编号 = func_id;
END UPD_SYSFUNCTION;

using System.Data;

using System.Data.OracleClient;
using HHSCInfor.App_Code.Database;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
AbsDB conn = DBConn.GetDBConn();
OracleCommand cmd = new OracleCommand();
cmd.CommandText = "UPD_SYSFUNCTION";
OracleParameter para1 = new OracleParameter("func_id", 4);
OracleParameter[] paraValue ={ para1};
int resultFlag = conn.ExeSql(CommandType.StoredProcedure, cmd.CommandText, paraValue);
Label1.Text = resultFlag.ToString();conn.Close();
}
}
CREATE OR REPLACE PROCEDURE UPD_SYSFUNCTION
(
func_id char,
flag char
)
IS
BEGIN
update infomanager.sysfunction
set 标志 = flag
WHERE 功能编号 = func_id;
END UPD_SYSFUNCTION;

cmd.CommandText = "UPD_SYSFUNCTION";
OracleParameter para1 = new OracleParameter("func_id", 4);
OracleParameter para2 = new OracleParameter("flag", 1);
OracleParameter[] paraValue ={ para1, para2 };
int resultFlag = conn.ExeSql(CommandType.StoredProcedure, cmd.CommandText, paraValue);
Label1.Text = resultFlag.ToString(); conn.Close();
}
}
