Can anyone explain the difference between the following descriptor members?
LENGTH
OCTET_LENGTH
RETURNED_LENGTH
RETURNED_OCTET_LENGTH
From looking at the source code, the last two are identical and it looks like they return the length of an individual row/column value (i.e. for a varchar column, they would return the length of an actual varchar value).
I think OCTET_LENGTH will return the size of the column as stored in the database.
I can't quite figure out what LENGTH is supposed to do. It returns PQfmod( ) - VARHDRSZ. How is that different from the OCTET_LENGTH?
Thanks in advance.
