I'm guessing you could write a program where you have an update statement:

UPDATE TABLE
SET MYBLOBCOL = :ABLOBPARAM
WHERE MYKEY = :AKEYPARAM

Prepare it and then loop through your records and call ExecSQL for each
record to be inserted.

MyUpdateQry.Prepare;

<start transaction>

while not <EndOfRecordsToProcess> do
begin
...
MyUpdateQry.Params[ 0 ].LoadFromFile( AFilename );
MyUpdateQry.Params[ 1 ].AsString := KeyValueAsString;
MyUpdateQry.ExecSQL;
...
end;

<commit transaction>
