以编程方式ADO.NET创建Oracle数据库和模式

Question

如何在ADO.NET中以编程方式创建oracle数据库,并使用userId + password为其创建模式,这样我就可以转到我不喜欢的工具sql oracle开发人员工具,我只需创建一个连接进入:

• 连接字符串名称
• 用户ID(架构)
• 密码

Answer 1

我以前用SQL做过但从未尝试过用ADO.NET ...

string connectionString = "...";
string oracleDataPath = "C:\\PATH_TO_ORADATA\\";

string username = "NEW_USER";
string password = "NEW_PWD";
string schema = "NEW_SCHEMA";

using (OracleConnection conn = new OracleConnection(connectionString))
{
    conn.Open();
    OracleCommand cmd = conn.CreateCommand();
    cmd.CommandText = "CREATE TABLESPACE \"" + schema + "\" DATAFILE '" + oracleDataPath + schema + ".DBF' SIZE 10M AUTOEXTEND ON NEXT 1M";
    cmd.ExecuteNonQuery();
    cmd.CommandText = "CREATE USER \"" + username + "\" IDENTIFIED BY \"" + password + "\" DEFAULT TABLESPACE \"" + schema + "\" TEMPORARY TABLESPACE TEMP";
    cmd.ExecuteNonQuery();
    cmd.CommandText = "GRANT CONNECT TO \"" + username + "\"";
    cmd.ExecuteNonQuery();
    cmd.CommandText = "ALTER USER \"" + username + "\" QUOTA UNLIMITED ON \"" + schema + "\"";
    cmd.ExecuteNonQuery();
}

在连接字符串上使用ADMIN/DBA帐户.
将oracleDataPath设置为Oracle保存其数据文件的路径.

让我知道它是否有效:-)
