need:

nlen = UnsafeNativeMethods.sqlite3_column_bytes(stmt._sqlite_stmt, index);
if (bDest == null) return nlen;

if (nCopied + nStart > bDest.Length) nCopied = bDest.Length - nStart;
if (nCopied + nDataOffset > nlen) nCopied = nlen - nDataOffset;

if (nCopied > 0) {
    ptr = UnsafeNativeMethods.sqlite3_column_blob(stmt._sqlite_stmt, index);
    Marshal.Copy((IntPtr)(ptr.ToInt64() + nDataOffset), bDest, nStart, nCopied);
} else nCopied = 0;
