To get the length in bytes of a LOB, use the FNC_GetLobLength Teradata library function. The function returns the length as an FNC_LobLength_t type, defined in the sqltypes_td.h header file like this:

typedef unsigned long FNC_LobLength_t;

For detailed information on FNC_GetLobLength, see C Library Functions.
