[杂]SQL Server 之 SSIS 实例

1 使用导入导出向导来建立简单SSIS包

2 不使用向导来建立简单SSIS包

有5个基本概念需要清楚：

• Connections
• Tasks
• Precedence constraints
• Event handlers
• Variables

连接

任务

流程控制

事件处理

变量

3 稍微复杂点的运用

1 从数据库中读取数据导入到Excel中。

（连接，任务，变量）

2 容器

For容器

string Count = Dts.Variables["Count"].Value.ToString();

MessageBox.Show(Count);

序列容器：

序列容器使用广泛：

3 以编程的方式创建

创建包

using System;
using Microsoft.SqlServer.Dts.Runtime;

namespace Microsoft.SqlServer.Dts.Samples
{
class Program
{
static void Main(string[] args)
{
Package package;
package = new Package();
}
}
}

创建任务

using System;
using Microsoft.SqlServer.Dts.Runtime;

namespace Microsoft.SqlServer.Dts.Samples
{
class Program
{
static void Main(string[] args)
{
Package p = new Package();

// Add a File System task.
Executable eFileTask1 = p.Executables.Add("STOCK:FileSystemTask");
TaskHost thFileHost1 = eFileTask1 as TaskHost;

// Add a second File System task.
Executable eFileTask2 = p.Executables.Add("STOCK:FileSystemTask");
TaskHost thFileHost2 = eFileTask2 as TaskHost;

// Put a precedence constraint between the tasks.
// Set the constraint to specify that the second File System task cannot run
// until the first File System task finishes.
PrecedenceConstraint pcFileTasks =
p.PrecedenceConstraints.Add((Executable)thFileHost1, (Executable)thFileHost2);
pcFileTasks.Value = DTSExecResult.Completion;
}
}
}
