程序集:  Microsoft.SqlServer.BulkInsertTask(在 Microsoft.SqlServer.BulkInsertTask.dll 中)

语法

声明
Public Property TableLock As Boolean
    Get
    Set
用法
Dim instance As BulkInsertTask
Dim value As Boolean

value = instance.TableLock

instance.TableLock = value
public bool TableLock { get; set; }
public:
virtual property bool TableLock {
    bool get () sealed;
    void set (bool value) sealed;
}
abstract TableLock : bool with get, set
override TableLock : bool with get, set
final function get TableLock () : boolean
final function set TableLock (value : boolean)

属性值

类型:System. . :: . .Boolean
true if you want to lock the table during the bulk insert; false if you do not want to lock it.

实现

IDTSBulkInsertTask. . :: . .TableLock

示例

The following example creates a BulkInsertTask, and then shows the default settings of the properties, including the TableLock, by using the TaskHost. The example then sets two fields to demonstrate how to set field values.

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Tasks.BulkInsertTask;

namespace Microsoft.SqlServer.SSIS.Samples

    class Program
    {
        static void Main(string[] args)
        {
            Package pkg = new Package();
            Executable exec1 = pkg.Executables.Add("STOCK:BulkInsertTask");
            TaskHost th = exec1 as TaskHost;

            // List the default values of the Bulk Insert task
            // by using the Properties collection of the TaskHost.
            Console.WriteLine("BatchSize             {0}", th.Properties["BatchSize"].GetValue(th));

            Console.WriteLine("SortedData            {0}", th.Properties["SortedData"].GetValue(th));
            Console.WriteLine("SourceConnection      {0}", th.Properties["SourceConnection"].GetValue(th));

            Console.WriteLine("--------------------------");
            // Show how to set a property by using the TaskHost Properties.
            th.Properties["CheckConstraints"].SetValue(th, true);
            th.Properties["DataFileType"].SetValue(th, DTSBulkInsert_DataFileType.DTSBulkInsert_DataFileType_Native);
            Console.WriteLine("New value of CheckConstraints and DataFileType:  {0}, {1}", th.Properties["CheckConstraints"].GetValue(th), th.Properties["DataFileType"].GetValue(th));
