No, because it is exactly what isql does: execute a prepared statement for each line of data. No magic inside. > I think this solutions will do!!!! External tables has a definite limitations, for example you cannot put NULL into it. If it is ok for you - fine. Otherwise the fastest way is export data into a file on one side, compress, transfer to other side, uncompress and then parse the file and insert records one-by-one in a single transaction. Firebird 4 has some kind of batch interface, but I'm not sure if it can speed up bulk load. -- WBR, SD. ------------------------------------ ------------------------------------ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Visit http://www.firebirdsql.org and click the Documentation item on the main (top) menu.
