- Properties specific to mongoOperationDeleteAll variables:
mongoOperationDeleteAll (Type of variable) In french: mongoOpérationSuppressionTout
The mongoOperationDeleteAll type is used to define all the advanced characteristics of a document delete operation that will be added to a bulk operations list. All the documents that match the selection filter will be deleted. The characteristics of this operation can be defined and changed using different WLanguage properties. To be executed, this delete operation will have to be added to the array of operations handled by MongoExecuteOperations. Remark: For more details on the declaration of this type of variable and the use of WLanguage properties, see Declaring a variable.
