我喜欢在下面的代码中使用FILENAME
的参数,而不是N'D:\ DBName.mdf'和N'D:\ DBName.ldf'。
如何在.sql
文件中更改它以及如何使用参数从C#调用它?
感谢。
SQL脚本:
CREATE DATABASE [DBName] ON PRIMARY
( NAME = N'DBName', FILENAME = N'D:\DBName.mdf' , SIZE = 3072KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB )
LOG ON
( NAME = N'DBName_log', FILENAME = N'D:\DBName.ldf' , SIZE = 3456KB , MAXSIZE = 2048GB , FILEGROWTH = 10%)
END
C#代码
string appPathDB = Path.GetDirectoryName(Application.ExecutablePath) + "\\DBName.mdf";
string appPathLog = Path.GetDirectoryName(Application.ExecutablePath) + "\\DBName_log.ldf";
private void CreateDatabase()
{
string connection = "Data Source=localhost;Initial Catalog=master;User ID=sa;Password=abcd1234";
FileInfo file = new FileInfo(Path.GetDirectoryName(Application.ExecutablePath) + "\\DBName.sql");
string script = file.OpenText().ReadToEnd();
ExecSql(script, connection, "DBName");
file.OpenText().Close();
}
public void ExecSql(string sql, string connectionString, string dataBaseNameToPrepend)
{
using (SqlConnection conn = new SqlConnection(connectionString))
{
conn.Open();
Server server = new Server(new ServerConnection(conn));
server.ConnectionContext.ExecuteNonQuery(sql);
server.ConnectionContext.Disconnect();
server.ConnectionContext.ExecuteNonQuery(sql);
MessageBox.Show("DB Uploaded.");
}
}

对您的脚本文件进行以下更改并保存。
CREATE DATABASE [DBName] ON PRIMARY
( NAME = N'DBName', FILENAME = N'DB_NAME_MDF' , SIZE = 3072KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB )
LOG ON
( NAME = N'DBName_log', FILENAME = N'DB_NAME_LDF' , SIZE = 3456KB , MAXSIZE = 2048GB , FILEGROWTH = 10%)
END
将以下行添加到您的代码中。
private void CreateDatabase()
{
string connection = "Data Source=localhost;Initial Catalog=master;User ID=sa;Password=abcd1234";
FileInfo file = new FileInfo(Path.GetDirectoryName(Application.ExecutablePath) + "\\DBName.sql");
string script = file.OpenText().ReadToEnd();
script = script.Replace("DB_NAME_MDF", appPathDB).Replace("DB_NAME_LDF", appPathLog);
ExecSql(script, connection, "DBName");
file.OpenText().Close();
}

我认为有不同的方法可以解决这个问题。
但据我所知,在这里寻找工作的简单方法可以是
创建一个名为dbcreate.sql的文件
CREATE DATABASE [DBName] ON PRIMARY
( NAME = N'DBName', FILENAME = XXXMDFXXX , SIZE = 3072KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB )
LOG ON
( NAME = N'DBName_log', FILENAME = XXXLDFXXX , SIZE = 3456KB , MAXSIZE = 2048GB , FILEGROWTH = 10%)
END
将此文件保存在应用程序中的某个位置,并使用C#代码读取此文件,并将XXXMDFXXX
的值替换为参数值N'D:\Work\DBLocation\Files\Employee.mdf'
和XXXLDFXXX,将其替换为第二个参数值N'D:\Work\DBLocation\Files\Employee.ldf'
将新文件保存在新位置并使用新名称dbMainCreate.sql
成功完成保存后,请按照您的代码使用新参数创建数据库。
注意:在存储新文件之前,如果是,则可以检查文件是否已在该位置可用,然后删除现有文件,然后保存。您还可以将文件移动或复制到其他位置以保持版本控制。
