[Copy link]
Post time 21-3-2007 02:56 PM | Show all posts |Read mode
erm,aku ada satu pertanyaan mengenai stored procedure yg aku buat ni..
bile aku run kan skrip ni, die menyebab kan data dalam database aku hilang.. huhu..
walhal aku takde letak statement delete pun..
boleh tak korg suggest ape sebabnye data tu hilang ye.. aku kasi contoh mcm kat bawah ni la..

a = 50, b =25
katakan a = a - b

so,sepatutnye.. hasil dia 25 jugakla kan.. tp result die tak menunjukkan ape2 nilai pada a tersebut...

anyone? ade idea tak? kenape boleh jadi mcm ni?

database gune oracle..
so, skrip ni involved 3 table dari database yg same...
erm.. sepatutnye bile buat insert value, field pada kl dan mn tu akan beri nilai....
(fyi, kl dan mn ade dalam tablesatu dan tabletiga)
tp bile buat select statement, takdelah plak nilai tu... huhu
btw, thank you in advance

sama seperti di kes di bawah jugak

update namadatabase.tabletiga set
   kl = v_kl - v_op,
   mn = v_mn - v_op
   where a_seq = v_a_seq;


waktu kat sini v_a_seq ko tak assign aper2 value jugak ,
jadi dia tak dapat buat update pasal takde value a_seq yg sama dengan v_a_seq


so make sure all variable tue ader value

select gh,ij into v_gh,v_ij from namadatabase.tabledua
where kjb = v_k_jb and year = v_year ;


year tu aku comparekan dengan v_year dr tablesatu


update namadatabase.tabletiga set
   kl = v_kl - v_op,
   mn = v_mn - v_op
   where a_seq = v_a_seq;


untuk yg ni plak aku comparekan a_seq dgn v_a_seq.. memanf kena letak value jugak ke?
tpkan yang aku musykil tu..
kenapa value dalam kl dan mn tu boleh hilang ye lepas aku run kan skrip ni?
kalaulah dia tak update table tu.. for sure value lama ade lagi kan?
betul ke?
