当count = 0时，如何在plsql过程中放置​​条件，然后调用过程或按原样继续

Question

我正在像PLSQL中的正常过程一样以oracle形式编辑过程，其中在过程结束时我要创建一个新条件，当count = 0时调用另一个过程，否则就继续执行

我终于在iam编辑的过程中尝试了此块

select count(*) into cnt_num from Af900MB where BRN_CD = :global.br_cd  
and KEY1 = 'SCONC_EXCLUSION_BOR_CAT'
and KEY2 = 'Variable '
and PARAM_VAL = 'Y';
if cnt_num  = 0 then 
*****
elsif cnt_num <> 0  then 
****    
end if
end;

但是我不知道如果..或者如果..或者我不知道这是否正确

下面是我的整个过程，我的编辑是该过程的最后一个

ENDDEFINE PROCEDURE

如果计数为0，则调用过程“ auth_proc”，否则按原样继续

Answer 1

那将很简单

if cnt_num  = 0 then 
   auth_proc;
end if;
