在sql server之间复制数据库
本文关键字:复制 数据库 之间 server sql | 更新日期: 2023-09-27 18:15:03
我正在开发一个用于在SQL服务器之间复制数据的Web应用程序。该工具将允许您指定从哪个服务器复制/复制到哪个服务器,然后将特定的数据库(始终具有相同的名称)从源服务器复制到目标服务器。
最好的方法是什么?数据可能非常大,所以速度也需要考虑在内。
我的尝试是尝试运行我使用SQL Server管理工作室创建的SSIS包。包存储在本地。
计划是修改Source和Destination连接字符串并启动包。
这是我的代码:
public void DataTransfer(String sourceConnection, String destConnection, String pkgLocation)
{
Package pkg;
Application app;
DTSExecResult pkgResults;
try
{
app = new Application();
pkg = app.LoadPackage(pkgLocation, null);
foreach (ConnectionManager connectionManager in pkg.Connections)
{
SqlConnectionStringBuilder builder;
switch (connectionManager.Name)
{
case "SourceConnection":
builder = new SqlConnectionStringBuilder(sourceConnection);
builder.Remove("Initial Catalog");
builder.Add("Initial Catalog", "StagingArea");
var sourceCon = builder.ConnectionString + ";Provider=SQLNCLI;Auto Translate=false;";
//Added spaces to retain password!!!
sourceCon = sourceCon.Replace(";", "; ");
connectionManager.ConnectionString = sourceCon;
Debug.WriteLine(connectionManager.ConnectionString.ToString());
break;
case "DestinationConnection":
builder = new SqlConnectionStringBuilder(destConnection);
builder.Remove("Initial Catalog");
builder.Add("Initial Catalog", "StagingArea");
var destCon = builder.ConnectionString + ";Provider=SQLNCLI;Auto Translate=false;";
//Added spaces to retain password!!!
destCon = destCon.Replace(";", "; ");
connectionManager.ConnectionString = destCon;
Debug.WriteLine(connectionManager.ConnectionString.ToString());
break;
}
}
pkgResults = pkg.Execute();
}
catch (Exception e)
{
throw;
}
Debug.WriteLine(pkgResults.ToString());
}
当pkg
执行时,我得到以下异常:
A first chance exception of type 'System.Runtime.InteropServices.COMException' occurred in Microsoft.SqlServer.ManagedDTS.dll
A first chance exception of type 'Microsoft.SqlServer.Dts.Runtime.DtsComponentException' occurred in Microsoft.SqlServer.ManagedDTS.dll
我真的不知道从这里去哪里,有什么主意吗?
我将编写一个SSIS包来进行数据复制/转换,网站将简单地配置连接字符串并启动包。
