以编程方式创建Oracle数据库和架构ADO.NET [英] Create Oracle database and schema programmatically ADO.NET

问题描述

如何在ADO.NET中以编程方式创建oracle数据库并使用userId +密码为其创建架构，因此我可以转到我最不喜欢的工具sql oracle developer工具，在其中创建连接输入:

• 连接字符串名称
• UserId(schema)
• 密码

解决方案

我以前用SQL做到过，但从未尝试过使用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保留其数据文件的路径.

让我知道它是否有效:-)

How can I create a oracle database programmatically in ADO.NET and a schema for it with userId + password so I can just go to my non-favorite tool the sql oracle developer tool where I just create a connection entering:

• connectionstring name
• UserId(schema)
• password

解决方案

I've done it with SQL before but never tried with 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();
}

Use the ADMIN/DBA account on the connection string.
Set oracleDataPath with the path where your Oracle keeps its data files.

Let me know if it works :-)
