Compare Records In A Table In Both Oracle - MSSQL?
Jan 13, 2009
I am trying to compare records in a table in both Oracle and MSSQL database against a single standard dataset in my test case. However, I'm getting different results for each when I sort using a "order by".
select COL1 from TABLE1 order by COL1
In MSSQL, I get:
COL1
=====
A
A.
A++
A++.
In ORACLE, I get:
COL1
=====
A
A++
A++.
A.
I mean, oracle result some what makes sense, because "." has bigger ascii value than "+". But is there anyway to make the ORACLE sort order look exactly like MSSQL result?

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)

I have got a procedure that successfully creates an oracle external table and populates it with the contents of a file. This works fine until I have a situation where one of the fields is a VARCHAR2(2) and I try to insert say, a 5 character value. When this happens the record in question does not get populated in the external table (and rightly so), but I could do with working out if there is a discrepancy in the number of records in the file and the number of records that actually make it into the table so I could inform the user that there is a problem.
I have attached the code that creates the external table and populates it.

I must create an INSERT trigger, on an Oracle table, which will do an insert into my MS-SQL 2000 DB table.
The tables are exactly the same in this case and I desire to insert the entire row that was just insterted into the Oracle table into the MS-SQL table.
I understand how to create an ODBC connection between the DB servers, I just can't seem to understand the trigger syntax.

Currently,I have this objective to meet. I need to query the database for certain results. After done so, I will need to compare the records: For example: the query return me with 10 rows of records, I then need to compare: row 1 with 2, row 2 with 3, row 3 with 4 ... row 9 with 10. The final result that I wish to have is 10 or less than 10 rows of records.
I have one approach currently. I do this within a function, hand have the variables call "previous" and "current". In a loop I will always compare previous and current which I populate through the record set using a cursor.
After I got each row of filtered result, I will then input it into a physical temporary table. After all the results are in this temporary table. I'll do a query on this table and insert the result into a cursor and then returning the cursor.
The problem is: how can I not use a temporary table. I've search through online about using nest tables. but somehow I just could not get it working.
how to replace the temp table with something else? or is there other approach that I can use to compare the row columns with other rows.

I need to compare records in the two columns (varchar). I need to find almost the same names from that columns.
For instance:
'MAPE STUD' <-> MAPE STUDY
And I should see that these records are the same because different is only in the one word.

I am trying to update records in the target table based on the records coming in from source. For instance, if the incoming record is present in the target table I would update them in the target else I would simply insert. I have over one million records in my source while my target has 46 million records. The target table is partitioned based on calendar key. I implement this whole logic using Informatica. Looking at the informatica session log I find that the informatica code is perfectly fine but its in the update part it takes long time (more than 5 days to update one million records). find the TARGET TABLE query and the UPDATE query as below.
TARGET TABLE:
CREATE TABLE OPERATIONS.DENIAL_REGRET_FACT
(
CALENDAR_KEY INTEGER NOT NULL,
DAY_TIME_KEY INTEGER NOT NULL,
SITE_KEY NUMBER NOT NULL,
RESERVATION_AGENT_KEY INTEGER NOT NULL,
LOSS_CODE VARCHAR2(30) NOT NULL,
PROP_ID VARCHAR2(5) NOT NULL,
[code].....

On a Oracle 11g R2 I've a table function ( PIPELINED ) returning rows selected from a table.The first time the function is selected, in a session ( I've tried to disconnect and log in again ), it returns no rows.I've tried to log the call using DBMS_OUTPUT and from what I see the select on the table function returns no rows and no output is printed. So I presume Oracle is not calling the function.
The same function on a similar environment ( same db versions, patches and database structure ) works fine. The second environment is a production environment so it has more memory and some other settings enabled.

create table a(sourcerow number(2), test_level number(2), dpn varchar2(1), qty number(5)); T
he insert scripts are as follows:
insert into a values(1,3,'Y',5); insert into a values(2,2,'Y',4); insert into a values(3,3,'N',3); insert into a values(4,4,'Y',3); insert into a values(5,1,'N',6); insert into a values(6,2,'N',5); insert into a values(7,2,'Y',4); insert into a values(8,3,'N',2); insert into a values(9,4,'Y',2); insert into a values(10,1,'Y',3); . SQL>select * from v$version; Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production
My logic should have the output as follows without 5th column: sourcerowleveldpnqtyremark13Y522Y4This row in main table shouldn't be displayed in the query result as it has
dpn='N'44Y3*3=9In this row qty=9 will bedisplayed.
It will compare the value of level column with its previous row level col,if it is the parent of the current(ex.current is 4 and previous is 3 parent of 4),then it will check the dpn of previous row ,if dpn='N' then qty of parent will be multiplied with qty of current row and displayed under qty column.this row will not be displayed as dpn='N'this row will not be displayed as dpn='N'72Y4*6=24in its previous row level value is same so it will check the previous to previous row where level is 1(parent of current row) and dpn='N' ,then it will multiply the qty of that row with current row and display the value in qty column.this row will not be displayed as dpn='N'94Y2*2=4In this row qty=4 will be displayed.It will compare the value of level column with its previous row level col,if it is the parent of the current(ex.current is 4 and previous is 3 parent of 4),then it will check the dpn of previous row ,if dpn='N' then qty of parent will be multiplied with qty of current row and displayed under qty column.101Y3It will not check for the previous rows as level 1 doesn't have any parent.

I use APEX 4.2.0. In Tabular form, I have column of Select list type. This list has too many values and the end user must choose all these values along the tabular form rows. In other words, If the LOV consists of X, Y , Z, The End user should add three rows and choose a unique value for each row.
The problem is : This LOV is supposed to have too many values. What comes to mind is:
1- Whenever the end user picks a value, this value should disappear from the LOV of the second row ? But I have no clue how to do it?
OR
2- Whenever the end use picks a value, I should notify him/her about the remaining values that he should pick . But I have no clue how to do it ?
At the end the purpose is to make the user aware that he still has some rows to add ( values to choose ... )
I simplified the issue in simple example here:
[URL]......
workspace: somefeto
user: test
