Syntax Rules for Describing the Data Stream
<longfile_code_spec> ::= <code_spec > | BINARY
With this specification, you define the default value for the interpretation of LONG data streams.
Using this syntax rule, you can also transform LONG data between various code types when you load or unload the data.
If you are loading/unloading ASCII LONG data into an ASCII database or UCS2 LONG data into a UNICODE database, the data does not have to be converted.
The following combinations are possible (internal database data type and external data type):
Internal Database Data Type |
Possible code attributes of the LONG data stream during unloading |
LONG ASCII |
ASCII, UCS2, UTF8 |
LONG UNICODE |
UCS2, UTF8 |
LONG BYTE |
BINARY, ASCII (HEX), UCS2 (HEX), UTF8 (HEX) |
Internal Database Data Type |
Possible code attributes of LONG data stream during loading |
LONG ASCII |
ASCII |
LONG UNICODE |
ASCII, UCS2, UTF8 |
LONG BYTE |
BINARY, ASCII, UCS2 (HEX), UTF8 (HEX) |
