sqlite3_column_bytes should do what you need. -----Original Message----- From: sqlite-users-boun...@sqlite.org [mailto:sqlite-users-boun...@sqlite.org] On Behalf Of Paolo Bolzoni Sent: Thursday, April 18, 2013 7:02 AM To: sqlite-users@sqlite.org Subject: [sqlite] sqlite3_column_blob does not return the size of the blob? I need to save some blob (arbitrary precision numbers representations) on my sqlite3 database. And confused by the function: const void *sqlite3_column_blob(sqlite3_stmt*, int iCol); I would expect an output parameter (example type size_t*) to get the size of the blob, but it is not there. How can I know the length of the blob to read it correctly?
