NET 连接到 Oracle，连接串如何写
我现在用的是 System.Data.OracleClient.dll
但是老抱错 OCI.dll无法加栽
有没有做这个方向的朋友，帮帮忙

* ODBC


o New version:
"Driver={Microsoft ODBC for Oracle};Server=OracleServer.world;Uid=Username;Pwd=asdasd;"


o Old version:
"Driver={Microsoft ODBC Driver for Oracle};ConnectString=OracleServer.world;Uid=myUsername;Pwd=myPassword;"


* OLE DB, OleDbConnection (.NET)


o Standard security:
"Provider=msdaora;Data Source=MyOracleDB;User Id=UserName;Password=asdasd;"

This one's from Microsoft, the following are from Oracle

o Standard Security:
"Provider=OraOLEDB.Oracle;Data Source=MyOracleDB;User Id=Username;Password=asdasd;"


o Trusted Connection:
"Provider=OraOLEDB.Oracle;Data Source=MyOracleDB;OSAuthent=1;"


* OracleConnection (.NET)


o Standard:
"Data Source=MyOracleDB;Integrated Security=yes;"

This one works only with Oracle 8i release 3 or later

o Specifying username and password:
"Data Source=MyOracleDB;User Id=username;Password=passwd;Integrated Security=no;"

This one works only with Oracle 8i release 3 or later

o Declare the OracleConnection:

C#:
using System.Data.OracleClient;
OracleConnection oOracleConn = new OracleConnection();
oOracleConn.ConnectionString = "my connection string";
oOracleConn.Open();



VB.NET:
Imports System.Data.OracleClient
Dim oOracleConn As OracleConnection = New OracleConnection()
oOracleConn.ConnectionString = "my connection string"
oOracleConn.Open()

Missing the System.Data.OracleClient namespace? Download .NET Managed Provider for Oracle >>

Great article! "Features of Oracle Data Provider for .NET" by Rama Mohan G. at C# Corner

* Core Labs OraDirect (.NET)


o Standard:
"User ID=scott; Password=tiger; Host=ora; Pooling=true; Min Pool Size=0;Max Pool Size=100; Connection Lifetime=0"

Read more at Core Lab and the product page.

* Data Shape


o MS Data Shape:
"Provider=MSDataShape.1;Persist Security Info=False;Data Provider=MSDAORA;Data Source=orac;user id=username;password=mypw"

建议使用oleDB连接oracle,减少很多错误！

[MarcuseXiao]

你应该不是连接字符吕串的问题,而是用户权限的问题,你看看这个用户有连接的权限吗?
因为你的程序报的是OCI.dll无法加栽的错误.

Oracle客户端装了吗？正常吗？

[interboy]

首先 有没有权限,其次客户端是否安装
开始 -> 程序 -> Oracle -> Configuration and Migration Tools ->
Net Manager→本地→概要文件→Oracle高级安全性→验证→去掉所选方法中的 "NTS" 就可以了.

安装客户端，要是VS05用Datasource控件可以很轻松生成各种连接字符串，复制下来就行。不用写

估计不是连接字符串的问题，接分好了
