Home -> Community -> Usenet -> c.d.o.misc -> [Q]HowTo get the count of selected rows
Hello,
Is it possible to construct a new SQL statement from an arbitrary SELECT statement which will always simply return the number of rows which would be selected by the original query?
For example, suppose I had the following:
SELECT DISTINCT fld1,fld2 FROM table1;
How can one quickly determine the number of rows that this statement will match without actually returning the data. I could simply issue the query twice, and count the rows the first time, but I need better performance. If DISTINCT was not present in the query above, one could simply say
SELECT COUNT(*) FROM table1;
Using stored procedures is not an option for us at this point because our CORBA RDBMS server won't properly invoke stored procedures in Oracle. We are using Oracle 7.3.2.
Thanks
