I have recently added support for the IBatch interface to IBX and the
good news that it all appears to work fine. However, I am still puzzled
by why inline blobs exist.
For as long as I can remember, Firebird has allowed you to over-ride the
input metadata SQLType to any other type that can be converted to the
actual column type. For example, SQL_BLOB to SQL_VARYING. You can then
pass a relatively short blob string as an SQL_VARYING (character id to
OCTETS for binary, and otherwise as appropriate) and with no need to go
to all the hard work of actually creating a blob,etc. I assume that it
is on the server side that the string gets written into blob storage and
would not expect it to be otherwise.
In all my testing, passing blob text as SQL_VARYING works fine for both
normal update/insert operations and for batches using IBatch. So I am
puzzled as to why the IBatch inline blob exists. What am I missing?
