HRESULT GetMultipleColumnUpdate(LPBOOL pRetVal);

HRESULT SetMultipleColumnUpdate(BOOL NewValue);

Remarks

When set to TRUE (the default), MultipleColumnUpdate specifies that multiple columns are updated using a single UPDATE statement. When MultipleColumnUpdate is set to FALSE, separate update statements are generated for each column changed.

Setting MultipleColumnUpdate to TRUE can result in an increase in performance. An application should set MultipleColumnUpdate to FALSE if it is necessary to maintain compatibility SQL Server 7.0 or earlier. An application should also set MultipleColumnUpdate to FALSE if triggers are defined for one or more columns.

MultipleColumnUpdate cannot be modified after the MergeArticle2 object is created.

Note  If an application calls MultipleColumnUpdate on an instance of SQL Server version 7.0, the constant, SQLDMO_E_SQL80ONLY, and the message "This property or method requires Microsoft SQL Server 2000" are returned.
