How are you inserting the blob?

If you are using sqlite3_bind_blob, be sure to give the correct size (maybe you 
are inadvertently using strlen() or similar to compute a length?).
Are you using SQLITE_STATIC, SQLITE_TRANSIENT or passing a destructor function?

When retreiving the value, you should be calling sqlite3_column_blob() first 
(which makes sure the column is a blob and returns the address), and then 
sqlite3_column_bytes() to get the size.

Betreff: [sqlite] Read Blob Returning bytes till NULL Terminated String

Hi Sir,

I have a requirement of reading an image data (BLOB) from a database.
I could successfully read the length of the blob using
sqlite3_column_bytes() but when i try to read the entire blob using 
sqlite3_column_blob(), i am getting undesired results.

I am getting the bytes till NULL terminated string is present. In my case, only 
3 bytes of data are being returned by the method.
Is there any way that if we specify the length, the whole blob data is 
retrieved irrespective of the NULL bytes .

Thanks and Regards,
Kishor Reddy
