This may sound mundane, but why not use a subselect COUNT?

SELECT COUNT(
select concat('Test row ',currentreturnrownum()) as testdata , mytestdata from mytestdatatable FROM mytestdatatable;

(I can't test this as I don't have currentreturnrownum() and cannot find this function in v.5).

You may also want to try the SQL_CALC_FOUND_ROWS and then FOUND_ROWS() to get the result.

SELECT SQL_CALC_FOUND_ROWS,
concat('Test row ',currentreturnrownum()) as testdata , mytestdata from mytestdatatable;
SELECT FOUND_ROWS();

J.R.

Subject: Counting Row Results inside the select

Has anyone found a way to get a result set with the current row return
number in a select statement without using vars?

select concat('Test row ',currentreturnrownum()) as testdata , mytestdata
from mytestdatatable;

+------------------------+-------------------+
|Test row 1 | testdata |
|Test row 2 | testdata |
|Test row 3 | testdata |
|Test row 4 | testdata |
|Test row 5 | testdata |
|Test row 6 | testdata |
|Test row 7 | testdata |
|Test row 8 | testdata |
|Test row 9 | testdata |
+------------------------+-------------------+
(9 rows returned)

Wishing you the best you know you deserve,
