我的sql代碼有問題。我嘗試創建一個觸發器,它將總結我在「關閉」遊覽之後獲得的收入。通過關閉我的意思是更新一行並輸入收費(付款),日期和時間。PLS-00103:遇到下列其中一項時遇到符號「'」:()
這裏的表:
create table Excursion(
excIDExcursion NUMBER(4) PRIMARY KEY ,
excStartDate date not null,
excStartTime varchar(5) not null,
excEndDate date,
excEndTime varchar(5),
excpayment number(8),
cIDCustomer number(4) references Customer,
ID_TaxiCab number(4) references TaxiCab
);
這裏是這個觸發器,它有一個錯誤:
create or replace trigger HowMuchWeEarned
after update on Customer
for each row
declare sumofearning number;
begin
if(excendtime!='' and exceenddate!=null)
then
Select sum(excpayment) into sumofearning from Excursion;
dbms_output.put_line(‘We’ve earned’||sumofearning);
end;
/
show errors;
錯誤表明這一點:
PLS-00103: Encountered the symbol "‘" when expecting one of the f ollowing: () - + case mod new not null <an identifier> <a double-quoted delimited-identifier> <a bind variable> table c ontinue avg count current exists max min prior sql stddev sum variance execute multiset the both leading trailing forall mer ge year month day hour minute second timezone_hour timezone_mi nute timezone_region timezone_abbr time timestamp interval dat e <a string literal with character set specificatio
有可能是一個問題這個if語句,但我找不出什麼是錯的。 在此先感謝。
感謝您的幫助! :) 不幸的是,現在它顯示了另一個問題: PLS-00103:遇到符號「;」當期待以下其中一個時:如果 – Ganjira
