SQL & PL/SQL :: Oracle 9i - Block Logic To Fetch Records From Table And Compare
Dec 26, 2011 the following proble.The emp table is having 14 records.
SELECT * FROM emp ORDER BY empno;
EMPNOENAMESALDEPTNO
7369SMITH80020
7499ALLEN160030
7521WARD125030
[code]...
The emp table is having 10 records.
SELECT * FROM emp_10 ORDER BY empno;
EMPNOENAMESALDEPTNO
7369SMITH80020
7499ALLEN160030
7521WARD125030
7566JONES200020
[code]...
I have written the following PL/SQL block logic tofetch the records from the emp table and compare the records with emp_10 table to perform insert if the records are newelse to perform update the existed records in the emp_10 table.
DECLARE
CURSOR tranche_balance_cur
IS
SELECT empno,
ename,
sal,
[code]...
Execution scenario 1:
I have commented insert and update statements in that case I got the following out put.
Inserted Records4
Updated Records10
As per the logic it's giving the correct output because the cursor is fetching 14 records in that already 10 records are existed in emp_10 tableand 4 are new records.so that it's showing the count for inserted records as 10 and updated records as 4.
Execution scenario 2:
I have uncommented insert and update statements in that case I got the following out put.
Inserted Records13
Updated Records1
As per the logic it's not giving the correct output.
I tried with using TRIM function in the comparision logic to avoid spaces.
TRIM(emp_10.empno) = TRIM(tranche_balance_rec.empno)
AND TRIM(emp_10.ename) = TRIM(tranche_balance_rec.ename)
AND TRIM(emp_10.sal) = TRIM(tranche_balance_rec.sal)
AND TRIM(emp_10.deptno) = TRIM(tranche_balance_rec.deptno)

The 01:40 record will come from our nightly command:
BACKUP INCREMENTAL LEVEL=0 FILESPERSET=20 FORMAT 'full_%d_%t_%s_%p'
DATABASE INCLUDE CURRENT CONTROLFILE
The 11AM records will come from the command:
BACKUP INCREMENTAL LEVEL=0 FORMAT 'ctl_%t_%s_%p' CURRENT CONTROLFILE;
(I know backups shouldn't still be running at 11am and we don't need level 0 backups every night, that's a seperate issue I'll be addressing! ) I see there's been a similar entry here in v$backup_datafile for all backups that there's records for. The database is up and running just fine. There are no unusual errors being reported by the database in OEM or the alert log.I tried looking at both our control files (yes, should have 3 - something else I've listed to change!) with dbverify which showed no issues - though I'm not sure if this is designed to work with control files.
If so, how could I confirm whether it's an issue with a specific controlfile (I'm assuming it's not an issue with the backup to tape itself, as it's reporting the same corruption every day)?I'd obviously like to diagnose this now while the db is up and running, rather than at 4am some morning during a crash and finding out my backup control files are no good!

2.) Is the block size is same for all blocks in a table and in Database or it varies?
