BulkInsertTask.BatchSize 属性

定义

命名空间:

Microsoft.SqlServer.Dts.Tasks.BulkInsertTask

程序集:

Microsoft.SqlServer.BulkInsertTask.dll

获取或设置每批的行数。

public:
 property long BatchSize { long get(); void set(long value); };

public long BatchSize { get; set; }

member this.BatchSize : int64 with get, set

Public Property BatchSize As Long

属性值

Int64

一个 Long 类型的值，指示每个批处理中的行数。

示例

The following example creates a BulkInsertTask, and then shows the default settings of the properties, including the BatchSize, by using the TaskHost. 然后，该示例设置两个字段，以显示如何设置字段值。

示例输出：

BatchSize 0

CheckConstraints False

CodePage RAW

DataFileType 0

DebugMode False

DestinationConnection

DestinationTableName

FieldTerminator 选项卡

FireTriggers False

FirstRow 1

FormatFile

KeepIdentity False

KeepNulls False

LastRow 0

MaximumErrors 0

RowTerminator {CR}{LF}

SortedData

SourceConnection

SqlStatement System.String[]

SuspendRequired False

TableLock False

UseFormatFile False

--------------------------

CheckConstraints 和 DataFileType 的新值：True、1

注解

默认值为 0，表示整个数据文件。 如果设置为 BatchSize 零，则会在单个批处理中加载数据。
