JOIN 2 tables that have same column ?

I need to learn how to join two tables that both have the same column name:
tbl1 - idskey
tbl2 - idskey
the idskey column holds a id_number
When I do the JOIN I would like to make sure that only Distinct records are joined from both tables and that any duplicates are removed in the final join. So if:
Tbl1 has a idskey of: 12345
and
Tbl2 has a idskey of: 12345
In the final JOIN I want to remove one of those duplicates.
I actually need to join 3 tables that have the same linking column names for the join, but if I learn how to do this correctly on 2, that will be a start.
10g for db, thanks!

Hi,
SELECT DISTINCT and GROUP BY are the most common ways to get unique results from non-unique keys. Exactly how you use them depends on exactly what you want to do.
SELECT DISTINCT guarantees that no two rows in the result set, conisdering all columns, will be identical.
GROUP BY produces one row from a set of rows that have a common feature. The values on that row may be a composite of values from various rows in that set (e.g., an average).
Please post a small, specific example. For instance:
"I have two rows in tbl1 ...
and these fhtee rows in tbl2 ...
Notice how there is one row with idskey=12345 in tbl1 but two such rows in tbl2.
How can I get theses results ...
where only one row has idskey=12345?"

Trying to join two views that have different column types

I want to join view1 and view2 on region and city int columns. Need to break apart View1 varchar field into two Int fields and replace any non-numeric values with zeros.
View1 has a single Region_City field that is VARCHAR. the last record is erroneous. the individual values for Region and City should always be Int.
0001-8374
0222-0034
3333-0001
XXA-EEE
View2 has Region and City as two seperate Int columns (i will seperate with comma just for display)
Region,City
1,8374
222,34
3333,1
I want to create two new individual columns in view1 that will have Region and City each as a Int. And for any Region_city that is invalid numeric just use zeros in Region and City.
I currently have this (in house ParseDelimited sproc), but am having trouble with the invalid numeric values (XXAA-EEE)
REPLACE(LTRIM(REPLACE(dbo.ParseDelimited (Region_City, '-', 1), '0', ' ')), ' ', '0') as Region,
REPLACE(LTRIM(REPLACE(dbo.ParseDelimited (Region_City, '-', 2), '0', ' ')), ' ', '0') as City,

This is a way to do it, by no means the only way, but a way. (The other way to achieve this would work fine, but would require functions inside functions inside other functions, including repeating at the very least "Patindex('-', RegionCity)"
a few times. In this situation, the APPLY statement comes in handy by making it a little easier to read.
Declare @ExampleTable Table (RegionCity Varchar(99))
Insert @ExampleTable /* This is just to recreate a test table */
Select '0001-8374'
UNION ALL Select '0222-0034'
UNION ALL Select '3333-0001'
UNION ALL Select 'XXA-EEE'
UNION ALL Select 'a really bad error, no numbers or dash at all'
UNION ALL Select '1-2'
UNION ALL Select '12345678-98765432'Select RegionCity
   , Cast( Coalesce( Case When IsNumeric(RegionCode) = 1 then RegionCode else '0000' End, '0000') as Int) as RegionCode
   , Cast( Coalesce( Case When IsNumeric(CityCode) = 1 then CityCode Else '0000' End, '0000') as Int) as CityCode
From @ExampleTable
Outer Apply (Select CharIndex('-', RegionCity) as DashPos) CaDash
Outer Apply (Select Substring(RegionCity, 1, DashPos - 1) as RegionCode
                   , SubString(RegionCity, DashPos + 1, 99) as CityCode where DashPos > 0) as CA2
You didn't mention how bad the source data might be, how unpredictable it might be, whether it's always coded exactly as listed. This way is reasonably flexible.
EDIT: I used "IsNumeric" in this example. It's quite an imperfect function, often best avoided, but I used here just because it's probably OK in this example.
This is probably better: "Case When PatIndex('%[^0123456789]%', CityCode) = 0 Then CityCode else 0 End"

When migrating from 10g to 11g with tables that have LOB columns, should the columns be converted to Securefile LOB formats?

We have an ongoing debate over the merits of switching to securefile LOBS. This is Oracle recommended approach but what are the main benefits?
Thsi would allow parallel impdp to take place also has benefit for compression, but are there any other driving factors to consider?

The fact that a hacking solution works well with a particular binary file on a particular database does not guarantee that it will not destroy another file and another database beyond repair. In case this happens, people will call Oracle Support for help. And Oracle Support may refuse (though it tries not to do this without reason) to help with such a corrupted database. This is a consequence of "unsupported" modifications to binary files. Therefore, publishing this type of advice with little or no word of warning nor disclaimer is simply irresponsible (especially, if simpler and supported solutions exist).
I did not suggest that you should waste time checking if your particular solution had already been documented or not but I did suggest that you see if the methods you proposed were documented. And, frankly speaking, this is not what an Oracle DBA should really have to check. I also cannot believe that you are not aware that modification of files in any undocumented binary format (not only Oracle's) is generally unsupported. And, while common and somehow acceptable in low-risk home or research applications, such modifications are a bad idea in high-risk production business use.

Can I create a view based on two tables that have the same column name?

I have two tables A and B. Each table has 50+ columns.
I want to create a view that includes all the columns in A and all the columns in B. I created a view with a select statement that says
Select A.*, B.*
From A, B
where A.id = B.id
It returns an error because in each table I have a column that keeps track if a record has been changed called Modified_By. That's where it chokes up on I figure. I would like to write the view without explicitly writing each column name from A and B as part of the select statement. The actual select statement works fine and only bombs when trying to turn the select statement into a view.

You will have to type the full column list at least once. You can save a few keystrokes (i.e. alias. on every column) by providing the column names to the CREATE part instead of in the SELECT part. Something like:
SQL> desc t
Name                                      Null?    Type
ID                                                 NUMBER
NAME                                               VARCHAR2(10)
SQL> desc t1
Name                                      Null?    Type
T_ID                                               NUMBER
LOC_ID                                             NUMBER
NAME                                               VARCHAR2(15)
SQL> CREATE VIEW t_v (id, t_name, t_id, loc_id, t1_name) AS
2 SELECT t.*, t1.*
3 FROM t, t1
4 WHERE t.id = t1.t_id;
View created.HTH

Deleting from multiple tables where few tables have same column name

Hi,
I am new to PL/SQL and need some help. I need to delete data older then X years from some 35 odd tables in my schema and out of those tables 25 tables have same column name on which i can have my "where" clause and rest 10 table have different table names. I am doing something like this :

UTL_FILE.FCLOSE(table_list);
END;
WHERE the text file "text7.txt" contains list of table name and column names separated by a pipe line. But when I execute the above proc it gives error "invalid table name".
Can something like this be done or is there any other way to execute this task of deletion from 35 tables.
Thanks.

Thanks for replies. I don't know what I am doing wrong but still not getting this damn thing work...This is the proc i am running now :

Best way to outer join a table that is doing a sub query

RDBMS : 11.1.0.7.0
Hello,
What is the best way to outer join a table that is doing a sub query? This is a common scenario in EBS for the date tracked tables.
SELECT papf.full_name, fu.description
FROM fnd_user fu
      ,per_all_people_f papf
WHERE fu.user_id = 1772
   AND fu.employee_id = papf.person_id(+)

                                     WHERE per1.person_id = papf.person_id)Output:
No output produced because the outer join cannot be done on the sub queryIn this case I did a query in the FROM clause. Is this my best option?

Shadow tables that have been created via the new partitioning schema

Hi,
     Complete Partitioning :
                In a complete partitioning, the fact table of the infocube are fully converted using shadow
tables that have been created via the new partitioning schema.
               in the above Explanation what is the meaning of shadow tables which perform the
               partitioning of an info cube.

Hi
Shadow tables have the namespace /BIC/4F<Name of InfoCube> or /BIC/4E<Name of InfoCube>.
Complete Partitioning
Complete Partitioning fully converts the fact tables of the InfoCube. The system creates shadow tables with the new partitioning schema and copies all of the data from the original tables into the shadow tables. As soon as the data is copied, the system creates indexes and the original table replaces the shadow table. After the system has successfully completed the partitioning request, both fact tables exist in the original state (shadow table), as well as in the modified state with the new partitioning schema (original table). You can manually delete the shadow tables after repartitioning has been successfully completed to free up the memory. Shadow tables have the namespace /BIC/4F<Name of InfoCube> or /BIC/4E<Name of InfoCube>.
You can only use complete repartitioning for InfoCubes. A heterogeneous state is possible. For example, it is possible to have a partitioned InfoCube with non partitioned aggregates. This does not have an adverse effect on functionality. You can automatically modify all of the active aggregates by reactivating them.
Hope it helps and clear

Can you use insert .. returning .. so you do not have to select the empty_clob back out.
[I have a similar problem but I do not know the primary key to select on, I am really looking for an atomic insert and fill clob mechanism, somone said you can create a clob fill it and use that in the insert, but I have not seen an example yet.]

Best way to join 2 columns from table A to same column in Table B?

Hi,
This is a simplified example of the query I'm trying to write.
I have two tables - PIPELINE (which includes columns CREDIT_RECEIVER and CREATOR) and EMPLOYEES (which includes columns EMAIL and LOB).
I want to write a query which joins PIPELINE.CREDIT_RECEIVER with EMPLOYEES.EMAIL to return LOB as "CREDIT_RECEIVER_LOB".
I also want this query to join PIPELINE.CREATOR with EMPLOYEES.EMAIL to return LOB as "CREATOR_LOB".
Currently, I am doing a left outer join on EMPLOYEES.EMAIL = PIPELINE.CREDIT_RECEIVER to get "CREDIT_RECEIVER_LOB", and calling a function GET_LOB(PIPELINE.CREATOR) (defined below) to get "CREATOR_LOB".
Query:
Select PIPELINE.ID as ID,
PIPELINE.CREDIT_RECEIVER as CREDIT_RECEIVER,
PIPELINE.CREATOR as CREATOR,
EMPLOYEES.LOB as CREDIT_RECEIVER_LOB,
GET_LOB(PIPELINE.CREATOR) as CREATOR_LOB
FROM PIPELINE
LEFT OUTER JOIN EMPLOYEES ON PIPELINE.CREDIT_RECEIVER=EMPLOYEES.EMAIL
Is there a more efficient way to write this query? This query is so slow that it usually times out on me.
Thanks,
Forrest

How do I select rows from the same table that have multiple occurances

Hi Everybody,
I am trying to select records from a detail table by grouping it. The table has more than 1 million records and the query is not performing well. The basic question is how to select a distinct record from a table which matches all values in one column and any in the other.
desc SCV
ID NUMBER PK (ID + SCRID)
SCRID NUMBER FK(SC)
ID SCRID
1 1
2 1
3 1
4 2
5 2
6 3
7 4
8 4
desc PROJECTS
ID NUMBER PK
NAME VARCHAR2(100)
ID NAME
1 PROJECT1
2 PROJECT2
3 PROJECT3
4 PROJECT4
desc PJS
ID NUMBER
PROID NUMBER FK (PROJECTS)
SCRID NUMBER FK (SCV(SCRID + SCVID)
SCVID NUMBER
ID PROID SCRID SCVID
1 1 1 1
2 1 1 2
3 1 2 5
4 1 3 6
5 1 4 7
6 2 1 3
7 2 2 4
8 2 2 5
9 2 4 7
There are over 1 million records in PJS.
desc TBP
SCRID NUMBER
SCVID NUMBER
SCRID SCVID
1 1
1 2
1 3
2 4
2 5
3 6
4 7
4 8
The requirement is to select projects that have matching SCRID, SCVID from TBP such that
all distinct SCRID should match and within that and any SCVID match will do. (A "AND" between each SCRID and an "OR" for each SCVID in that SCRID like 'SCRID = 1 AND (SCVID = 1 OR SCVID = 2 OR SCVID = 3) AND SCRID = 2 AND (SCVID =....)
So, for the sample data it should return us PROID = 1
I have few queries written for this:
SELECT PROID FROM PJS,TBP WHERE TBP.SCVID = PJS.SCVID AND TBP.SCRID = 1
INTERSECT
SELECT PROID FROM PJS,TBP WHERE TBP.SCVID = PJS.SCVID AND TBP.SCRID = 2
INTERSECT
SELECT PROID FROM PJS,TBP WHERE TBP.SCVID = PJS.SCVID AND TBP.SCRID = 3
INTERSECT
SELECT PROID FROM PJS,TBP WHERE TBP.SCVID = PJS.SCVID AND TBP.SCRID = 4
This query performs well but the cost is very high, hardcoding, sorting.
The 2nd option is to:
SELECT pjs.PROID proid
FROM TBP tbp,
PJS pjs
WHERE pjs.SCVID = tbp.SCVID
AND pjs.SCRID = tbp.SCRID
GROUP BY pjs.PROID
HAVING COUNT(DISTINCT pjs.SCRID) = (SELECT COUNT(DISTINCT SCRID ) FROM TBP)
This has a low cost but runs slowly.
One more way I tried was with the IN operator like
SELECT DISTINCT PROID FROM PJS A,TBP T WHERE T.SCRID = 1 AND T.SCVID = A.SCVID
AND PROID IN (SELECT PROID FROM PJS A,TBP T WHERE T.SCRID = 2 AND T.SCVID = A.SCVID
AND PROID IN (...SO ON with each DISTINCT SCRID.
Again this involves too much of sorting.
Any help will be appriciated.
Thanks in advance.

Hi Andrew,
Use DELETE t_itab statement inside the loop.
I have modified your code. It is perfectly working.See bellow -
LOOP AT it_zmember01 INTO wa_zmember01.
WRITE: / wa_zmember01-mnumber UNDER 'NUMBER',
wa_zmember01-mname UNDER 'NAME',
wa_zmember01-mdob UNDER 'DOB'.
WRITE / '-----------------------------------------------------------------'.
DELETE it_zmember01. " Modified
ENDLOOP.
DELETE it_zmember01. statement inside the loop will delete the current row of the table.

Similarly, i've to rename the 'b' to different name , but make sure that the 'b' that have 5 as the key have the same name.
How can I achieve this in sql? I dont know how to use cursor and complex queries, as i'm new to SQL.

Counting Numnber of Cells in a Table that Have the Same Value

Is there a way/formula to do this, other than they way I'm doing it now, which is by using COUNTIF? In a table with 1000 rows for instance, let's say the values in the A column are what I'm keying off. I would like a count of all the cells in the A column that have the word "example" as their value. Right now for each unique value in a cell in the A column I am manually creating a COUNTIF(A1:A1000,"<value i'm matching against>) but if there are many unique values in the A column, it's quite laborious. Ideally I'd like to just have a table generated that gives me the top 5 or top 10 most occurring cell values in the A column in the table. What's the best way to do this?

So for instance, for a column like this:
1
1
1
2
2
4
5
I want a way to get back the number of times 1 appears in the list (3), the number of times 2 appears in the list (2), 4 (1), 5 (1), and so on. If I do a COUNTIF and there are thousands of rows, I have to manually put the matching string in each one.

How to join two tables with no similar columns

Hi all,
I have two tables as follows:
Table T1 have Attributes as follows:
GLCODE,
BRANCH,
ITEM_NUMBER,
DEMAND_DATE,
QUANTITY,
SOURCE
Table T2 have Attributes as follows:
FORECAST_DATE
Now in SQL if run the following stattement iam getting out put.
SELECT GLCODE,BRANCH,ITEM_NUMBER,DEMAND_DATE,QUANTITY, SOURCE,(SELECT DISTINCT FORECAST_DATE FROM T2) FROM T1
The above SQL Statement giving correct results for me.
The same SQL Statement how can we implement in mapping level?
Regards,
Ava

Jaap van,

You have to specify an outer join, but how do you do that if there is no join to begin with? I would do the following (which I didn't test yet):
add an extra column (say C_JOIN) to the T2-ingroup of the join operator and fill it with from a constant operator with say value 1. Then use T2.C_JOIN (+) = 1 as the join condition.
If every record in T2 is guaranteed to have the same value, instead of using a deduplicator, which will read all records, sort them and deduplicate them, you can use a filter with filter condition ROWNUM < 2, which only will read one record.
I am facing almost the same problem but not entirely thou and I was wondering if you have an idea how to even start.
Problem:

Re: Use PLSQL to delete tables dynamically
When the select is writing properly, the result of the five digit number from JOBID and the string should look like the below result (job_(five digit_%).
My problem is there is no relationship between ALL_TABLES and the my own table (ita.tpis32_job_status). Any help will be appreciated.

Table - PAC051TPROFORMA
Column - mrn,visitid
Table - PAC052MTRANSBILL
Column - mrn,visitid
Then i want to create a table view to view that table. This is my SQL
CREATE VIEW pacviewproforma (mrn,visitid,mrn,visitid,mrn,visitid)
As Select PAC051MPROFORMA.mrn,PAC051MPROFORMA.visitid,PAC051TPROFORMA.mrn,PAC051TPROFORMA.visitid,PAC052MTRANSBILL.mrn,PAC052MTRANSBILL.visitid
where
*(a.PAC051MPROFORMA.mrn=PAC051TPROFORMA.mrn)*
and
*(a.PAC051TPROFORMA.mrn=PAC052TRANSBILL.mrn)*
That SQL Return this error = ORA-00957: duplicate column name
Then I modify that SQL to
CREATE VIEW pacviewproforma (mrn,visitid)
As Select PAC051MPROFORMA.mrn,PAC051MPROFORMA.visitid,PAC051TPROFORMA.mrn,PAC051TPROFORMA.visitid,PAC052MTRANSBILL.mrn,PAC052MTRANSBILL.visitid
where
*(a.PAC051MPROFORMA.mrn=PAC051TPROFORMA.mrn)*
and
*(a.PAC051TPROFORMA.mrn=PAC052TRANSBILL.mrn)*
This time this error return = ORA-01730: invalid number of column names specified
What should i do?
Thanks...

Hi,
SQL> CREATE VIEW pacviewproforma (mrn,visitid,mrn,visitid,mrn,visitid)
2 As Select
3 PAC051MPROFORMA.mrn,
4 PAC051MPROFORMA.visitid,
5 PAC051TPROFORMA.mrn,
6 PAC051TPROFORMA.visitid,
7 PAC052MTRANSBILL.mrn,
8 PAC052MTRANSBILL.visitid
9 from PAC051MPROFORMA,PAC051TPROFORMA,PAC052MTRANSBILL
10 where
11 (PAC051MPROFORMA.mrn=PAC051TPROFORMA.mrn)
12 and
13 (PAC051TPROFORMA.mrn=PAC052MTRANSBILL.mrn);
CREATE VIEW pacviewproforma (mrn,visitid,mrn,visitid,mrn,visitid)
ERROR at line 1:
ORA-00957: duplicate column namePlease give different names to each column.
Something like this..
SQL> CREATE OR REPLACE VIEW pacviewproforma (MPROFORMA_mrn,MPROFORMA_visitid,TPROFORMA_mrn,TPROFORMA
_visitid,MTRANSBILL_mrn,MTRANSBILL_visitid)
2 As Select
3 PAC051MPROFORMA.mrn,
4 PAC051MPROFORMA.visitid,
5 PAC051TPROFORMA.mrn,
6 PAC051TPROFORMA.visitid,
7 PAC052MTRANSBILL.mrn,
8 PAC052MTRANSBILL.visitid
9 from PAC051MPROFORMA,PAC051TPROFORMA,PAC052MTRANSBILL
10 where
11 (PAC051MPROFORMA.mrn=PAC051TPROFORMA.mrn)
12 and
13 (PAC051TPROFORMA.mrn=PAC052MTRANSBILL.mrn);
View created.
SQL> DESC pacviewproforma;
