thanks for your support:
(i work with Oracle 8.0.6)
i made a procedure,in this procedure i have to query for a value and make some calculation with it:
query-----------------------------------------------
SELECT EVT.CODZN10 INTO zone10 FROM EVT WHERE EVT.CODSOC = CSOC/*parameter*/
AND EVT.ACHVTE LIKE ACVT
AND EVT.TYPEVE LIKE TYEV
AND EVT.NUMEVE = NUM
AND EVT.NUMPOS = POSTE
AND EVT.NUMBLO = 0
AND EVT.NUMSPO = 0
AND EVT.NUMLIG = 0;
ok,the codzn10 is a varchar2(12)and the query is correct,i have checked it through sql*plus.
The problem is after.When i want to make some calculation with it like:
quan1maj := ROUND (to_number(zone10) - (quantitecommandee * (poidsnet-poids)),5);
i thought it might work but it isn t.The problem seems to be the to_number statement,but if i don't put it,it still doesn t work.
If i do that :
dbms_output.put_line(zone10);
quan1maj := ROUND (to_number(zone10) - (quantitecommandee * (poidsnet-poids)),5);
dbms_output.put_line(zone10);
the first output will be shown but not the second.But i have the message that PL/SQL procedure is successfull!same thing if i don t put the to_number statement.
I'm lost,and weak...
