Detailed Description
Allows retrieving information about non query operations performed on the database.
An instance of this class will be returned on the CRUD operations that change the content of the database:
- On Table: insert, update and delete
- On Collection: add, modify and remove
Other functions on the Session class also return an instance of this class:
- Transaction handling functions
Member Function Documentation
◆ get_auto_increment_value()
| int get_auto_increment_value | ( | ) |
The last insert id auto generated (from an insert operation)
- Returns
- the integer representing the last insert id
For more details, see https://dev.mysql.com/doc/refman/en/information-functions.html#function_last-insert-id
Note that this value will be available only when the result is for a Table.insert operation.
◆ get_generated_ids()
| list get_generated_ids | ( | ) |
Returns the list of document ids generated on the server.
- Returns
- a list of strings containing the generated ids.
When adding documents into a collection, it is required that an ID is associated to the document, if a document is added without an '_id' field, an error will be generated.
At MySQL 8.0.11 if the documents being added do not have an '_id' field, the server will automatically generate an ID and assign it to the document.
This function returns a list of the IDs that were generated for the server to satisfy this requirement.
