私はOracleを初めて使用し、数時間苦労してきた問題があります。
サンプル:
Create Table Accounts (Id number(10),Balance number(16,3), Status Varchar2(50),Owner_Id number(10));
Create Table Transactions (Id number(10),Amount number(16,3), Trxn_date date, Account_Id number(10));
Create Table Owner (Id number(10), Firstname varchar2(50),Lastname varchar2(50));
Insert Into Accounts(Id,Balance,Status,Owner_Id) Values (1,1000,'OPEN',10);
Insert Into Accounts(Id,Balance,Status,Owner_Id) Values (2,5000,'CLOSED',11);
Insert Into Accounts(Id,Balance,Status,Owner_Id) Values (3,1000,'OPEN',12);
Insert Into Accounts(Id,Balance,Status,Owner_Id) Values (4,5000,'CLOSED',13);
Insert Into Accounts(Id,Balance,Status,Owner_Id) Values (5,1000,'OPEN',14);
Insert Into Accounts(Id,Balance,Status,Owner_Id) Values (6,5000,'CLOSED',15);
Insert Into Accounts(Id,Balance,Status,Owner_Id) Values (7,1000,'OPEN',16);
Insert Into Accounts(Id,Balance,Status,Owner_Id) Values (8,5000,'CLOSED',17);
Insert Into Accounts(Id,Balance,Status,Owner_Id) Values (9,1000,'OPEN',18);
Insert Into Accounts(Id,Balance,Status,Owner_Id) Values (10,5000,'CLOSED',19);
Insert Into Accounts(Id,Balance,Status,Owner_Id) Values (11,1000,'OPEN',20);
Insert Into Accounts(Id,Balance,Status,Owner_Id) Values (12,5000,'CLOSED',21);
Insert Into Owner(Id,Firstname,Lastname) Values (10,'John','TEST1');
Insert Into Owner(Id,Firstname,Lastname) Values (11,'John','TEST2');
Insert Into Owner(Id,Firstname,Lastname) Values (10,'John','TEST3');
Insert Into Owner(Id,Firstname,Lastname) Values (11,'John','TEST4');
Insert Into Owner(Id,Firstname,Lastname) Values (10,'John','TEST5');
Insert Into Owner(Id,Firstname,Lastname) Values (11,'John','TEST6');
Insert Into Owner(Id,Firstname,Lastname) Values (10,'John','TEST7');
Insert Into Owner(Id,Firstname,Lastname) Values (11,'John','TEST8');
Insert Into Owner(Id,Firstname,Lastname) Values (10,'John','TEST9');
Insert Into Owner(Id,Firstname,Lastname) Values (11,'John','TEST10');
Insert Into Owner(Id,Firstname,Lastname) Values (10,'John','TEST11');
Insert Into Owner(Id,Firstname,Lastname) Values (11,'John','TEST12');
Insert Into Transactions(Id,Amount,Trxn_Date,Account_Id) Values (1,10,'02-FEB-2015',5);
Insert Into Transactions(Id,Amount,Trxn_Date,Account_Id) Values (2,10,'02-APR-2015',5);
Insert Into Transactions(Id,Amount,Trxn_Date,Account_Id) Values (3,10,'02-JUN-2015',5);
Insert Into Transactions(Id,Amount,Trxn_Date,Account_Id) Values (4,10,'02-AUG-2015',5);
Insert Into Transactions(Id,Amount,Trxn_Date,Account_Id) Values (5,10,'02-FEB-2015',2);
Insert Into Transactions(Id,Amount,Trxn_Date,Account_Id) Values (6,10,'02-APR-2015',2);
Insert Into Transactions(Id,Amount,Trxn_Date,Account_Id) Values (7,10,'02-JUN-2015',2);
Insert Into Transactions(Id,Amount,Trxn_Date,Account_Id) Values (8,10,'02-AUG-2015',2);
データチェック:
Select Unique(Account_Id) From Accounts A
Inner Join Owner B on B.ID=A.OWNER_ID
Inner Join Transactions I on I.ACCOUNT_ID=A.Id
Where I.Trxn_date Between '01-FEB-2015' and '01-JUL-2015'
And A.Status='CLOSED'
and A.Balance=5000;/*1 Row Returned*/
ループは、返された最初の Id で終了する必要があります
Declare
l_NewDate date:='01-FEB-2015';
l_OldDate date:='01-JUL-2015';
l_pID number(10);
Begin
For I in (Select Account_Id From Transactions
Where Trxn_date Between l_NewDate and l_OldDate)
Loop
Select Id Into l_pID From
(Select B.Id From Accounts A
Inner Join Owner B on A.Owner_Id = B.Id
Where A.Status = 'CLOSED' And A.Balance = 5000 And A.Id=I.Account_Id)
Where rownum < 2;
dbms_output.put_line(l_pID);
Exit;
End Loop;
End;
ORA-01403: No data found
ORA-06512: at line 12
上記のデータチェックで明確に別のことが述べられているのに、なぜデータが見つからないのか理解できません。
