I try to export long binary field to text file and insert into to another database, but the export of the long binary will not be correct. I'm writing this way: SELECT long_binary_filed from testtable; output to 'c:\temp\Test1.txt' ENCODING 'utf-8'; What I'm wondering is how I can export long binary fields to a text file so I can add it to another database then with an insert? |

I suggest that you use xp_write_file() since it will not try to do any character conversion on the binary blob when it writes it to the file. Okay, thanks for the quick reply. If I then export this. SELECT xp_write_file( 'c:\temp\Test1.txt', long_binary_filed ) FROM testtable; Do I then read it with xp_read_file? How?

Yes, one way to read the file would be to use xp_read_file. begin declare @blob long binary; set @blob = xp_read_file( 'c:\temp\Test1.txt' ); ... end;

Then I do an insert (or update) like this? INSERT INTO testtable ( long_binary_field ) VALUES ( xp_read_file( 'c:\temp\Test1.txt' ) );

Yes, that should work.
