Syntax

FNC_LobLength_t
FNC_UdtGetSerializeSize(UDT_HANDLE  udt)

Syntax Elements

Usage Notes

Use the size returned by this function to allocate the buffer that will hold the serialized or deserialized data in calls to FNC_UdtSerialize and FNC_UdtDeserialize.

The upper limit on the amount of memory that a UDF can allocate using FNC_malloc is specified by the MallocLimit field in the cufconfig utility. For more information about cufconfig, see Teradata Vantageā„¢ - Database Utilities, B035-1102.

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