mongoOperationDeleteOne (Type of variable)
In french: mongoOpérationSuppressionUn
The mongoOperationDeleteOne type is used to define all the advanced characteristics of a document delete operation that will be added to a bulk operations list. The first document that matches the 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.
Example
MongoCreateCollection(base, "col1",optCol)
col is mongoCollection = base..Collection["col1"]
 
MongoDeleteAll(col,"{}")
MongoAdd(col, "{""item1"":""A"",""item2"":1}")
MongoAdd(col, "{""item1"":""a"",""item2"":2}")
MongoAdd(col, "{""item1"":3,""item2"":1}")
MongoAdd(col, "{""item1"":3,""item2"":2}")
MongoAdd(col, "{""item1"":4,""item2"":1}")
MongoAdd(col, "{""item1"":4,""item2"":2}")
MongoAdd(col, "{""item1"":5,""item2"":1}")
MongoAdd(col, "{""item1"":5,""item2"":2}")
MongoAdd(col, "{""item1"":6,""item2"":1}")
 
t is array of dynamic mongoOpération
 
opAdd is mongoOperationAdd
opAdd.Document = "{""item1"":1,""item2"":1}"

opUpdateOne.Update = "{ ""$inc"": {""item2"":10}}"
t.Add(opUpdateOne)
 
opUpdateAll is mongoOperationUpdateAll
opUpdateAll.Filter = "{""item1"":5}"

t.Add(opUpdateAll)
 
opReplace is mongoOperationReplaceOne
opReplace.Filter = "{""item1"":6}"
