A table based on 400 columns

Hi ,
What is the best way to create a dummy table which has 400 columns ,the column names being known?
Thanks.

Some of Oracle's limits are based on the checkbox on the sales brochure theory ... not on relational reality.
I have a table I am working with right now that has 921 columns. Designed by someone else at some distant point in the past and coming from a 1PB dataware house I am working with.
I can not tell you what I think of the design in this forum and maintain my relationship with Oracle: Use your imagination and somewhere in the phrase you dream up use the phrase "full frontal."

Import flat file to multiple tables based on identifier column

Hello,
I am trying to setup a package that will import one pipe-delimited flat file (a utility bill) to multiple data tables based on the value of the first column. I have been told it is similar in format to an EDI file, but there are some differences.
The number of columns is consistent where the first columns are the same. Meaning a record that has '00' in the first column will always have 10 columns; a record that has '01' in the first column will always have 9 columns; etc.
Each value in the first column represents a separate destination data table. Meaning a record that has '00' in the first column should be output to table '00'; a record that has '01' in the first column should be output to table '01'; etc. All
destination tables reside on the same SQL Server.
Identifier columns can repeat multiple times throughout the flat file. Meaning a record that starts with '01' may be repeated multiple times in the same.
Sample Data:
00|XXXXXXXX|XXX|XXXXXXXX|XXXXXX|XXXX|X|XXXXXXXXXX|XX|XXXXX
01|XXXXXXXXXXX|XXX|XXXXXXXX|XXXXX|XXXXXXXXXXXXXXXXXXXX|XXXXXXXXXX|XXXXXXX|XXXXXXXXXXXXXX
02|XXXXXXXXXXX|XXXXXXXX|XXXXXXX|XXXXX|XXXXX|XXXXX|XXXXX|XXXXX|XXXXX|XXXXX|XXXXX
04|XXXXXXXXXXX|XXXXXXXXXXXXX|XXX|XXXXXXXX
05|XXXXXXXXXXX|XXXXXXXXXXXXX|XXX|XXXXXXXX|XXXX
07|XXXXXXXXXXXXX|X|XXXXXXXXXXXXXXX|XXX|XXXXXXXX|XXXX|XXXXXXX|XXXXXXXXXXX
07|XXXXXXXXXXXXX|X|XXXXXXXXXXXXXXX|XXX|XXXXXXXX|XXXX|XXXXXXX|XXXXXXXXXXX
07|XXXXXXXXXXXXX|X|XXXXXXXXXXXXXXX|XXX|XXXXXXXX|XXXX|XXXXXXX|XXXXXXXXXXX
07|XXXXXXXXXXXXX|X|XXXXXXXXXXXXXXX|XXX|XXXXXXXX|XXXX|XXXXXXX|XXXXXXXXXXX
01|XXXXXXXXXXX|XXX|XXXXXXXX|XXXXX|XXXXXXXXXXXXXXXXXXXX|XXXXXXXXXX|XXXXXXX|XXXXXXXXXXXXXX
02|XXXXXXXXXXX|XXXXXXXX|XXXXXXX|XXXXX|XXXXX|XXXXX|XXXXX|XXXXX|XXXXX|XXXXX|XXXXX
04|XXXXXXXXXXX|XXXXXXXXXXXXX|XXX|XXXXXXXX
Any help would be appreciated.

Hi koldar.308,
If there are few distinct values in the first column, we can use Flat File Source connect to that flat file, then use Conditional Split Transformation to split the first column to multiples, and then load the data to multiple tables with OLE DB Destination
based on the outputs of Conditional Split.
After testing the issue in my environment, please refer to the following steps to achieve this requirement:
Drag a Flat File Source connect to that flat file with Flat File Connection Manager.
Drag a Conditional Split Transformation connects to the Flat File Source.
Double-click the Conditional Split Transformation, add several Output based on the first column values as below:
Drag same number OLE DB Destinations as the outputs of Conditional Split, connect to Conditional Split with one case output:
If there are any other questions, please feel free to ask.

Finding a TABLE based on a COLUMN NAME...

I need to find all tables that that have a common column name.
Upon searching the Forum, I found this nice nugget:
How to find the table in a schema if I only know a particular column name
The problem is, my USER_TAB_COLUMNS is EMPTY!
If it had worked, then my statement would be:
select * from USER_TAB_COLUMNS
where COLUMN_NAME LIKE '%TEST%'
and OWNER='ME';
I get "no rows selected" (though I know they exist)
if I do:
select * from USER_TAB_COLUMNS
I also get "no rows selected"
Any ideas!
Thanks!
KSL.

The user_xxx data dictionary tables show all of the whatevers that are owned by the logged in user. So, if you are logged in as user1 the user_tab_columns view will only show tables and views owned by user1.
The all_xxx dictionary views show all of the whatevers that the logged in user has access to. so if you are logged in as user1 and user2 gave you selet privileges on tablea, then you would see tablea in all_tab_columns.
The dba_xxx views show all objects in the database, but are generally only available to privileged users.
If you have access to the dba_views, try:
SELECT owner, object_type
FROM dba_objects
WHERE UPPER(object_name) = 'ANL'It is possible that the table and or its columns were created with double quotes so are case sensitve. It may also be a synonym, pointing to one of the tables that you got form your query.
If you are only using all_tab_columns then it is possible that the user you are logged in as does not have privileges on the table anl so would not see it in the view.
A long shot, but are you sure you are in the right database?

Compare two tables based on two columns

Hi,
my tables looks like this:
Desc Table A (account)
Account1_id
Account2_id
name,
empid
Table B (Bill )
BillNo
Advertiserid
agencyid
total vvalue
I need to pick up total value from table B where the unique combination of advertiser-Agency id is the same as the given account1_id -Account2_id combination in table A for each employee id.
In other words my output should be like
Empid | Account_id (should be same as advertiserid)| Account2_id (same as agencyid) | sum(total_value) for this adv-agency combination.....
objective: Get the total value from table B for each unique account1-account2 combination (advertiser-agency in other words) .
I am not sure if I should use a coreelated subquery or how to handle the situation....Right now I am just checking the two columns separately like this:
select.......from a,b
where b.advertiser_id = a.account1_id and b.agencyid = b.account2id
Is it correct to do so? I have a feeling that I am missing something if I join them seperately like this......Any advice on this?
I am using Oracle 10g. Hope I am clear.Please let me know. Thankx in advance.

Here you go:
SQL> WITH bill AS
2 (
3          SELECT 1000 AS billno, 101 AS advertiserid, 102 AS agencyid, 5000 AS total_value FROM DUAL UNION ALL

Filtering a Power Query Table Based on a Column That's a Table

I have a table produced by an outer join ...
"Bananas" is not one of [My Fruit] values. I'd like to filter my join results to only include [My Fruit] values, and I thought I could do that without expanding "NewCol".
Am I mistaken in my belief that such a selection can be done without expanding the "NewCol"?

hi Mark Weisman,
I suppose your [My Fruit] value is single values. You can try below :
Table.SelectRows( Join1, each List.Contains( [NewCol] [Fruit] , [My Fruit] ) )
Note: [Fruit] is the column that contain value want to filter.
Below is my testing sample :
let
Source = Table.FromRows({ {"North", "Apples"}, {"North", "Orange"}, {"West", "Bananas"},{"West", "Lemon"}}, {"Region", "Fruit"}),
Group = Table.Group(Source, {"Region"}, {{"NewCol", each _, type table}}),
Select = Table.SelectRows( Group, each List.Contains( [NewCol] [Fruit] , "Lemon" ) )
in
Select

Sorting A Table Based on single Column

Hi,
I wrote the piece of code to sort a webdynpro Table.
wdContext.nodeKMAccess().sortElements(
     new Comparator()
     public int compare(Object x, Object y)
     int iX,iY;
     IPrivateDownloadKMHitsReportView.IKMAccessElement rx = (IPrivateDownloadKMHitsReportView.IKMAccessElement)x;
     IPrivateDownloadKMHitsReportView.IKMAccessElement ry = (IPrivateDownloadKMHitsReportView.IKMAccessElement)y;
     iX = Integer.parseInt(rx.getHits());
     iY = Integer.parseInt(ry.getHits());
     rx.getHits().compareTo(ry.getHits());
     return (iY-iX);
But it sorts like
11
10
8
6
3
1
2
It sorts correctly, except for 2 values. Instead of 2 ,1... It gives 1,2. Where is the problem? how can i solve this isuue? Can anyone please help me in fixing this error?
Regards,
Divya

Hi,
try to change the comparator as follows
public int compare ( Object obj1, Object obj2 )
   int i1 = ( ( Integer ) obj1 ) .intValue ( ) ;
   int i2 = ( ( Integer ) obj2 ) .intValue ( ) ;
   return Math.abs ( i1 ) - Math.abs ( i2 ) ;

Dear Alll
I have a requirement to color the rows of a table based on a column value in it. I have tried and surfed many useful materials over the net. but none of them solves my purpose. Please help me, I know that i can used OADataBoundValueViewObject and create a custom css file and apply color to a particular column of a table using a decode in the select statement of that VO.
But all i need is to color a particular row with a particular color. Need your help with this ........

How to restrict a table with its set of data based on a column value in it?

Hi,
I have a scenario in which I have to show a set of data of a pivot table by restricting data based on a column value. I am creating BIP report whose source is from BIA ie.RPD. Based on a column value I want to restrict the data being displayed in the table. Since I also want the hidden data in the first table to be displayed in another table in the same report I cannot restrict the data at the query level i.e at RPD or at BIA. For this reason I used
<?xdofx:if saw3_ = 1?>
the pivot table
<?end if?>
But it does not restrict any data.
Also I tried using the if condition inside the table before the row level looping happens. But no good show even then.
How can I forgo this problem?

The MM

Update table based on ID reference comparing each column and value

Hi,
Through UI user can update any information and click save. In backend i will be receiving only ID as reference . Based on the ID value i should update multiple tables wherever i have the reference tables. Here i will not get the values or column name updated.
I just get a ID to find which row is updated.
I should do a comparision now.
I have a history table where i get the row before updation. and i get a row after updation from current data i.e. from ssdb_Railroad[This will be updated by java after updation we will get the ID inorder to update remaining tables]. Now i need to compare
both the table column values and know which column is updated and after getting the value i should update reference tables.
Below is the structure for comparision table , History table and Main table.
Create table Comparision_History (
ID int IDENTITY(1,1) PRIMARY KEY,
InsertUser_UpdateUser varchar(50),
Old_ColVal varchar(100),
New_ColVal varchar(100),
TableName varchar(100),
[Action] varchar(50),
InsertDate_UpdateDate Datetime NOT NULL DEFAULT getdate()
CREATE TABLE SSDB_Railroad_History (
ID int IDENTITY PRIMARY KEY,
SCAC varchar(4) ,
Name varchar(50) NOT NULL,
RailroadID int NOT NULL UNIQUE,
RC2Key
varchar(50),
NOTES varchar(1000),
[Action] varchar(50),
InsertDate_UpdateDate Datetime NOT NULL DEFAULT getdate(),
InsertUser_UpdateUser varchar(50),
CREATE TABLE SSDB_Railroad (
ID int IDENTITY(1,1)PRIMARY KEY,
SCAC varchar(4) UNIQUE,
Name varchar(50) NOT NULL,
RailroadID int NOT NULL UNIQUE,
RC2Key
varchar(50),
InsertDate Datetime NOT NULL DEFAULT getdate(),
UpdateDate Datetime,
InsertUser varchar(50),
UpdateUser varchar(50)
Here SSDB_Railroad table and History table needs to be compared and get a updated value and it should be inserted in a comparision table. as well as it should be updated in reference tables.
Please help me with the code.
Thanks in Advance
Deepa

Hi Deepa_Deepu,
According to your description, personally, the merge function can meet your requirements. Usually, we can synchronize two tables by updating or inserting rows in a target table based on differences found in the source tables. Just as your description, when
the value of ID and InsertDate_UpdateDate in the source table matches a value, update them in the target table. When the values does not match, the source row is inserted into the target table.
For more information, see: using MERGE to perform UPDATE and INSERT operations on a target table by using a derived source table.

Can anyone help me out to write a vb.net script.
I need to read the column names from excel and based on that column names I need to create a table in database(I have more than one sheet in excel).
For each sheet columns will be changing and should create a table dynamically for each sheet.
Any help would be appreciated.

Refer the below script to read columns in each sheet.
Dim excelfile As String = Dts.Variables("ExcelPath").Value.ToString
Dim connectionstring As String = "Provider=Microsoft.Jet.OLEDB.4.0;" +

For Each row As DataRow In dt.Rows
TABCOMMAND(TABCOUNT) = "SELECT * FROM [" & row.Item("TABLE_NAME").ToString & "]"
OLEDBCMD.CommandText = TABCOMMAND(TABCOUNT)
OLEDBCMD.Connection = oledbcon
oledbdatareader = OLEDBCMD.ExecuteReader(CommandBehavior.KeyInfo)
schemaTable = oledbdatareader.GetSchemaTable()

Update 1 column,1 single table based on where results of multiple tables

I would like the my_id column in 1 table updated to the static value of 247 for my_id stored in the 1 single table based on the where clause, which uses the my_id column in it.
The update statement updates all rows in table1, instead of just the rows where
the condition ( (b.my_id=a.my_id)
and ( b.my_name like 'OIS SrClerk%')
and (a.f_id=m.f_id)
and (trunc(m.cr_time) < '02-Apr-2008')) is true
What needs to be changed?
update table1 a
set a.my_id=247
from table1 a, table2 b, table3 m
where
(b.my_id=a.my_id)
and ( b.my_name like 'OIS SrClerk%')
and (a.f_id=m.f_id)
and (trunc(m.cr_time) < '02-Apr-2008')

Are you looking for this?
UPDATE table1 A
   SET A.my_id = 247
WHERE EXISTS (SELECT 'x'
                 FROM table2 b,
                      table3 M
                WHERE b.my_id = A.my_id
                 AND b.my_name LIKE 'OIS SrClerk%'
                 AND A.f_id = M.f_id
                 AND TRUNC (M.cr_time) < to_date('02-apr-2008 00:00:00','dd-mon-yyyy HH:MI:SS') )changed date string to to_date

Tabular Form based on table with lots of columns - how to avoid scrollbar?

Hi everybody,
I'm an old Forms and VERY new APEX user. My problem is the following: I have to migrate a form application to APEX.
The form is based on a table with lots of columns. In Forms you can spread the data over different tab pages.
How can I realize s.th similar in APEX? I definitely don't want to use a horizontal scroll bar...
Thanks in advance
Hilke

If the primary key is created by the user themselves (which is not recommended, you should have another ID which the user sees which would be the varchar2 and keep the primary key as is, the user really shouldn't ever edit the primary key) then all you need to do is make sure that the table is not populated with a primary key in the wizard and then make sure that you cannot insert a null into your varchar primary key text field.
IF you're doing it this way I would make a validation on the page which would run off a SQL Exists validation, something along the lines of
SELECT <primary key column>
FROM <your table>
WHERE upper(<primary key column>) = upper(<text field containing user input>);
and if it already exists, fire the validation claiming that it already exists and to come up with a new primary key.
Like I said if you really should have a primary key which the database refers to each individual record itself and then have an almost pseudo-primary key that the user can use. For example in the table it would look like this:
TABLE1
table_id (this is the primary key which you should NOT change)
user_table_id (this is the pretend primary key which the user can change)
other_columns
etc
etc
hope this helps in some way
