hi,
Is there any way I can get to know the count returned by
a cursor without actually fetching the cursor.
If this is not possible then is there a way I can get back the whole cursor after I fetch it.
In our case, we are using the output of the cursor in our java code.
If I fetch the cursor even once, I lose that row of data fetched in the Java code.
rgds,
Praveen

Well you could declare a numeric variable, then
SELECT COUNT (*)
INTO your_variable
FROM your_tables
WHERE your_where_clause
using the same table(s) and WHERE clause as the cursor will use before the cursor is fetched (or even before it is opened if you like).

hi,
Well we are presently using the above approach of getting the count first and then opening the cursor.
But my Where clause is very big and has multiple table joins causing the performance to be very slow.
Is there any other way to do it in a single statement.
rgds,
Praveen
