I have the query:
WITH STAN_IND
AS (
SELECT ro.kod_stanow, ro.ind_wyrob||' - '||ro.LP_OPER INDEKS_OPERACJA, count(*) ILE_POWT
FROM M_REJ_OPERACJI ro
JOIN M_TABST st ON st.SYMBOL = ro.kod_stanow
WHERE (st.KOD_GRST starting with 'F' or (st.KOD_GRST starting with 'T') ) AND ro.DATA_WYKON>'NOW'-100
GROUP BY 1,2)
SELECT S.kod_stanow, count(*) ILE_INDEKS, SUM(ILE_POWT-1) POWTORZEN
from STAN_IND S
GROUP BY S.kod_stanow
ORDER BY ILE_INDEKS
That should be working, but I get an error:
SQL Error [335544606] [42000]: Dynamic SQL Error; expression evaluation not supported; Strings cannot be added or subtracted in dialect 3 [SQLState:42000, ISC error code:335544606]
I tried to cast it into bigger varchar but still no success. What is wrong here? Database is a Firebird 2.1
