Entity Framework Extensions Ignore OnMergeInsert Expression
Description
The IgnoreOnMergeInsertExpression
allows you to ignore some columns when the BulkMerge
method executes the insert
statement and these columns will only be used in update
statement.
The following example ignores the Description
property in insertion and will be considered when updating the records.
using (var context = new EntityContext()) { context.BulkMerge(list, options => { options.IgnoreOnMergeInsertExpression = customer => new { customer.CustomerID, customer.Description }; }); }
