Overview
The Document functions support moving data into and out of the Document data type.
AsDocument
Convert value to type Document.
Syntax
AsDocument( value )
The required argument value may of type Unicode, TextVar, or Binary.
Remarks
Data Management converts value using the following implicit field conversion logic:
-
Unicode→Document: the Unicode string is assumed to contain the JSON representation of a BSON document, and is parsed.
-
TextVar→Document: the same as Unicode→Document, but not all code points can be represented.
-
Binary→Document: the Binary data is assumed to contain a UTF-8 encoded string. The Binary data is decoded into a string and then converted as per Unicode→Document.
Example
AsDocument('{"A":"a"}') returns 0E00000002410002000000610000
BSONToDocument
Convert native BSON bytes to type Document.
Syntax
BSONToDocument( binary )
The required argument binary must be native BSON.
Example
BSONToDocument( binary )
DocumentToBSON
Convert Document type to native BSON bytes.
Syntax
DocumentToBSON( document )
The required argument document must be of type Document.
Example
DocumentToBSON( NewDoc )
