Purpose
Determines whether a UDT supports serialization and deserialization.
Syntax
int
FNC_UdtSerializeSupported(UDT_HANDLE udt)
- UDT_HANDLE udt
- the handle of the UDT.
Return Value
- 1 : the UDT supports serialization and deserialization
- 0 : the UDT does not support serialization and deserialization
Usage Notes
The following UDTs support the serialize/deserialize interface. The formats that each UDT will use to serialize and deserialize data are as follows:
| UDT | Format |
|---|---|
| ST_Geometry | The serialized format is opaque. It is designed to be compact and efficient to serialize and deserialize. |
| XML | The serialized format is opaque. It is designed to be compact and efficient to serialize and deserialize. |
| JSON | The serialized format is the text string that represents the JSON data, and it is equivalent to the transformed value (FromSQL/ToSQL) of the JSON data type. |
