ServerBCPKeepNulls Property

未來的 Microsoft SQL Server 版本將移除這項功能。請避免在新的開發工作中使用這項功能，並規劃修改目前使用這項功能的應用程式。

The ServerBCPKeepNulls property controls the handling of missing values for all columns that accept NULL and possess a default value constraint when importing data.

語法

object.ServerBCPKeepNulls [= value]

Parts

• object
  An expression that evaluates to an object in the Applies To list

• value
  TRUE or FALSE

Data Type

Boolean

Modifiable

Read/write

Prototype (C/C++)

HRESULT GetServerBCPKeepNulls(LPBOOL pRetVal);
HRESULT SetServerBCPKeepNulls(BOOL NewValue);

備註

If TRUE, NULL is inserted when missing values are encountered in the data file. The default constraint does not supply a value for the column.

If FALSE, the default constraint provides a value for any missing values encountered in the data file. FALSE is the default value.

The ServerBCPKeepNulls property is interpreted only when data is imported and if the UseServerSideBCP property of the BulkCopy object is TRUE.
