[!INCLUDE SQL Server Azure SQL Database Azure SQL Managed Instance FabricSQLDB]
This function returns the number of qualifying rows currently in the last cursor opened on the connection. To improve performance, [!INCLUDE ssNoVersion] can populate large keyset and static cursors asynchronously. @@CURSOR_ROWS can be called to determine that the number of the rows that qualify for a cursor are retrieved at the time of the @@CURSOR_ROWS call.

@@CURSOR_ROWS
int
| Return value | Description |
|---|---|
-m |
The cursor populates asynchronously. The value returned (-m) is the number of rows currently in the keyset. |
-1 |
The cursor is dynamic. Because dynamic cursors reflect all changes, the number of rows that qualify for the cursor constantly changes. The cursor doesn't necessarily retrieve all qualified rows. |
0 |
No cursors are open, no rows qualified for the last opened cursor, or the last-opened cursor is closed or deallocated. |
n |
The cursor is fully populated. The value returned (n) is the total number of rows in the cursor. |
@@CURSOR_ROWS returns a negative number if the last cursor opened asynchronously. Keyset-driver or static cursors open asynchronously if the value for sp_configure cursor threshold exceeds 0, and the number of rows in the cursor result set exceeds the cursor threshold.
This example first declares a cursor, and then uses SELECT to display the value of @@CURSOR_ROWS. The setting has a value of 0 before the cursor opens and then has a value of -1, to indicate that the cursor keyset populates asynchronously.
