このコードは、条件が満たされている場合に適用します。構文エラーが発生するのは、エラーが発生していない場合のみですが、

IF condition THEN 
    ... ... 
ELSEIF condition THEN 
    ... ... 
END IF; 

ここmanualを参照してください。条件は、条件

Answer 1

場合の構文は、他の場合はこのようであれば、それは他に示し間違ってやっているところを私に提案してください場合は、他の適用されます。

IF search_condition THEN statement_list 
    [ELSEIF search_condition THEN statement_list] ... 
    [ELSE statement_list] 
END IF
