Forces all cursors to be non-scrolling.
DBA permissions are not required to set this option. Can be set temporary for an individual connection or for the PUBLIC group. Takes effect immediately.
By default, all cursors are scrolling. Scrolling cursors with no host variable declared cause Sybase IQ to create a buffer for temporary storage of results. Each row in the result set is stored to allow for backward scrolling.
Setting FORCE_NO_SCROLL_CURSORS to ON reduces temporary storage requirements. This option can be useful if you are retrieving very large numbers (millions) of rows. However if your front-end application makes frequent use of backward-scrolling cursor operations, query response will be faster with this option set to OFF.
If your front-end application rarely performs backward-scrolling, make FORCE_NO_SCROLL_CURSORS = ‘ON’ a permanent PUBLIC option, to use less memory and improve query performance.
