Default re: Counting Row Results inside the select

I'm sorry, currentreturnrownum() doesn't exist .. I was looking for a
function like that so I can make a result set show what row it is in the
return set.

so I can get select currentrownumber , * from anytable;

then I get
1 (rest of date from the *)
2 (rest of date from the *)
3 (rest of date from the *)
4 (rest of date from the *)
5 (rest of date from the *)
6 (rest of date from the *)
7 (rest of date from the *)
8 (rest of date from the *)

I only need to use it for exporting data to another database.





Wishing you the best you know you deserve,

re: Counting Row Results inside the select







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();

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)
