急！

请问如何用C#得到Oracle存储过程返回的记录集？

[dotnba]

看看System.Data.OracleClient

[csdn_bob]

如果是1.0,就设置参数的方式
如para.Direction = ParameterDirection.Output;
然后取就行了para.Value

[Soking]

DataSet dataSet = new DataSet();
Connection.Open();
SqlDataAdapter sqlDA = new SqlDataAdapter();
sqlDA.SelectCommand = BuildQueryCommand( storedProcName, parameters );
sqlDA.Fill( dataSet, tableName );
Connection.Close();
return dataSet

[Soking]

DataSet dataSet = new DataSet();
Connection.Open();
OleDbDataAdapter sqlDA = new OleDbDataAdapter();
sqlDA.SelectCommand = BuildQueryCommand( storedProcName, parameters ); //BuildQueryCommand生成一个sql命令
sqlDA.Fill( dataSet, tableName ); //tableName 为填充的表名
Connection.Close();
return dataSet //得到记录集

这应该是配置oracle实例的问题

你配时选择tcp/ip, 打上机器IP,端口默认,

比如建好一个实例叫 abc

那你直接通过Provider=MSDAORA.1;Password=11;User ID=user;Data Source=abc

就能访问了

如果实例没配好, c#估计也帮不上忙



不知道你需要什么。。。随便给你贴一个把。。。不过连接ORACLE数据库需要微软的一个补丁。。。不知道你有没有~要不用ole db连接很痛苦的。而且老出错

一样的啊，通过dataadapter执行查询，然后fill(dataset)

[xiaohuazi]

to all:
在Oracle中用过程返回结果集，必须借助包，返回一个参考游标，我在C#中如何调用这个包中的过程并且如何把这个结果集得到呢？
