SQLite C Interface

Open A BLOB For Incremental I/O

int sqlite3_blob_open(
  sqlite3*,
  const char *zDb,
  const char *zTable,
  const char *zColumn,
  sqlite3_int64 iRow,
  int flags,
  sqlite3_blob **ppBlob
);

Open a handle to the blob located in row iRow,, column zColumn, table zTable in database zDb. i.e. the same blob that would be selected by:

SELECT zColumn FROM zDb.zTable WHERE rowid = iRow;

If the flags parameter is non-zero, the blob is opened for read and write access. If it is zero, the blob is opened for read access.

On success, SQLITE_OK is returned and the new blob handle is written to *ppBlob. Otherwise an error code is returned and any value written to *ppBlob should not be used by the caller. This function sets the database-handle error code and message accessible via sqlite3_errcode() and sqlite3_errmsg().
