Deserializes data in the UDT’s serialized format back into the UDT.

Returns 0 if the operation was successful, 1 otherwise.

Syntax

int
FNC_UdtDeserialize (UDT_HANDLE        udt, 
                    BYTE             *buffer,
                    FNC_LobLength_t   data_length)

Syntax Elements

udt
the handle of the UDT.
buffer
the user buffer that contains the UDT value in its serialized format.
data_length
the length of the data in the buffer.

Usage Notes

When invoking FNC_UdtDeserialize, you must pass in a buffer that contains all of the serialized data. FNC_UdtDeserialize deserializes this data back into the UDT, but this must be done in a single call to FNC_UdtDeserialize.

The query will fail if the UDT does not support serialize/deserialize.
