+<blockquote><pre>

+</pre></blockquote>
+<p>
+This function is used to move an existing <a href="../c3ref/blob.html">BLOB handle</a> so that it points
+to a different row of the same database table. The new row is identified
+by the rowid value passed as the second argument. Only the row can be
+changed. The database, table and column on which the blob handle is open
+remain the same. Moving an existing <a href="../c3ref/blob.html">BLOB handle</a> to a new row is
+faster than closing the existing handle and opening a new one.</p>
+
+<p>The new row must meet the same criteria as for <a href="../c3ref/blob_open.html">sqlite3_blob_open()</a> -
+it must exist and there must be either a blob or text value stored in
+the nominated column. If the new row is not present in the table, or if
+it does not contain a blob or text value, or if another error occurs, an
+SQLite error code is returned and the blob handle is considered aborted.
+All subsequent calls to <a href="../c3ref/blob_read.html">sqlite3_blob_read()</a>, <a href="../c3ref/blob_write.html">sqlite3_blob_write()</a> or
+<a href="../c3ref/blob_reopen.html">sqlite3_blob_reopen()</a> on an aborted blob handle immediately return
+SQLITE_ABORT. Calling <a href="../c3ref/blob_bytes.html">sqlite3_blob_bytes()</a> on an aborted blob handle
+always returns zero.</p>
+
+<p>This function sets the database handle error code and message.
