        let _receiveTimeout = defaultArg receiveTimeout 0
*)
-> string

Parameters

filename String: The file name where the records are going to be created.
records String: Buffer of records to write. Inside this string are the recordIds, and the records.
newOptions NewOptions (Optional): Object with write options for the new record(s), including recordIdType, readAfter, calculated, dictionaries, conversion, formatSpec, originalRecords.
jsonFormat JSON_FORMAT (Optional): Enum JSON_FORMAT specifies the desired output format: standard JSON, JSON_DICT format, or JSON_SCH format
customVars String (Optional): Free text sent to the database allows management of additional behaviours in SUB.LK.MAIN.CONTROL.CUSTOM, which is called when this parameter is set.
receiveTimeout Int32 (Optional): Maximum time in seconds that the client will wait for a response from the server. Default = 0 to wait indefinitely.

Return Value

String

Remarks

Inside the records argument, the records always must be specified. But the recordIds only must be specified when NewOptions argument is null, or when the RecordIdType argument of the NewOptions constructor is null.
