Question

I have a little bit of an odd issue.

When I run this SQL:

with ID_Table as ( 
    select row_number() over (order By SS_ID) As row_id, 
             ss_id 
      from slide_show ) 
     select t0.* 
       from ID_Table as t1 
inner Join slide_show as t0 on t1.ss_id = t0.ss_id 
    where t1.row_id between 0 and 1 
 order by t1.row_id asc;

in SQL Express, it runs and returns the first row as it should (similar to the Limit 0,1 in MySQL). However, when I run this in delphi via the TADOQuery object, I receive the error in the title. I am guessing the ADO object is doing something along the way but I don’t understand what.

Note: This is the exact SQL I am passing into the ADO object.

Does anyone have any ideas?

Try:

SELECT t0.*
FROM (SELECT row_number() over(ORDER BY SS_ID) AS row_id, ss_id FROM slide_show) AS t1
INNER JOIN slide_show AS t0
ON t1.ss_id = t0.ss_id
WHERE t1.row_id BETWEEN 0 AND 1
ORDER BY t1.row_id ASC;
