Hello All,

I have a Table with a column of Image Datatype. I am trying to update an hexadecimal value from one database Image datatype column to another database image type column and when I am trying to do that, It is changing the hex value.

The original value copied from first table is
"0x47494638396151002900F70000000000800000008000808000000080800080008080808080C0C0C0FF000000FF00FFFF000000FFFF00FF00FFFFFFFFFF"

But when I am updating it, It is changing to

"0x424D464401000000000036000000280000004501000055000000010018000000000010440100000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000001000000000000000000000000010000010000010000010"

Please help me out.

SQL

UPDATE provider SET signature = '0x47494638396151002900F70000000000800000008000808000000080800080008080808080C0C0C0FF000000FF00FFFF000000FFFF00FF00FFFFFFFFFF' where ProviderID=1

Firsth thing I would do is loose the quotes:

SQL

UPDATE provider SET signature = 0x47494638396151002900F70000000000800000008000808000000080800080008080808080C0C0C0FF000000FF00FFFF000000FFFF00FF00FFFFFFFFFF where ProviderID=1

Since this is an Image field it will take quoted data as a character string rather than a binary stream.

But when I try it, using your string in either method abovce I get what I would expect: from yours the ASCI string for '0' 'x' '4' '7' ...
Without the quotes I get the right data. Are you sure you are reading the data correctly?
