[−][src]Struct odbc_api::RowSetCursor
A row set cursor iterates in blocks over row sets, filling them in buffers, instead of iterating the result set row by row. This is usually much faster.
Implementations
impl<'b, C, B> RowSetCursor<'b, C, B> where
C: Cursor, [src]
C: Cursor,
pub fn fetch(&mut self) -> Result<Option<&B>, Error>[src]
Fills the bound buffer with the next row set.
Return
None if the result set is empty and all row sets have been extracted. Some with a
reference to the internal buffer otherwise.
pub fn unbind(self) -> Result<C, Error>[src]
Unbind the buffer, leaving the cursor free to bind another buffer to it.
