insert a BLOB via a sql script?
For testing, you can insert literal hex bytes or use the RAWTOHEX(string) function, as shown below.
create table a(id integer, item blob);insert into a values(1,'54455354');insert into a values(2, RAWTOHEX('Test'));select UTF8TOSTRING(item) from a;TESTTestAddendum: For loading BLOB fields from a file, FILE_READ(fileNameString) may be a useful alternative.
insert into a values(3, FILE_READ('file.dat'));

Example code from the linked blog article, should the link break again:
CREATE TABLE MyTable (id int, image varbinary(max))INSERT INTO MyTable SELECT 1 ,(SELECT * FROM OPENROWSET( BULK 'C:\file.bmp', SINGLE_BLOB) as x )
