Select Distinct rows from multiple tables

Table 1 is a List of Vendors - VID, PID, VName, VAddress, VPhone
Table 2 is a list of Products - PID, PName, PPrice, PWeight, PColor
I need to produce a list of unique PID's showing the following fields - PID, VName, PName, PColor
So, Here is my failed attempt:
SELECT P.PID, V.VName, P.PName, P.PColor
FROM Products P INNER JOIN Vendors V ON P.PID = V.PID
GROUP BY P.PID

If you post DDL, sample data and your desired output based on that sample data, someone can probably create a query that does what you want.
And I have to tell you that Table 1 is not a list of vendors unless you have a system where a vendor provides one and only one product - something that is unusual. If your system is one where a vendor should provide any number of products (and if a product
can be provided by any number of vendors), you have some fundamental schema issues to correct.
Lastly, there are sticky posts at the top of the forum that provide suggestions for posting questions. Please have a look - help your readers help you by providing sufficient information. Phrases such as "failed" or "does not work"
do not provide any useful detail. And one good rule of thumb - any time you feel you need to use (or say) distinct in a query is an indication that something somewhere is wrong. It could be a schema issue, a misunderstanding of the schema or the
goal, an incorrect query, etc. There are few instances where distinct is needed in a well-defined and implemented system, IMO.

Select Distinct rows from 3 tables

I need to retrive information from 3 different tables by applying a specific condition.
I have the following query which works fine for retrieving desired data from 2 tables.
SELECT
a.userId
FROM userGeneral
a inner
join userSpecific
b on a.userId
= b.userId
WHERE
a.userActive
= 1
userId
111
222
333
444
Now I have a third table called userMgr which may contain multiple records for each userId with a corresponding mgrId value. It has a primary key identity column called userRecId and I would like to fetch the
mgrId value corresponding to the MAX(userRecId) for the matching userId.
userRecId  | userId  | mgrId
1 |    111    | 123
2 | 111 | 234
3 | 111 | 345
4 | 333 | 345
5 | 333 | 456
The resultset should be as follows after joining all the 3 tables.
userId | mgrId
111 | 345
222 | NULL
333 | 456
444 | NULL
Can anyone please help with this query.

How can i select some row from multiple row in the same group of data

I want to select some row from multiple row in the same group of data.
ColumnA
Column B
1 OK
1 NG
2 NG
2 NG
3 OK
3 OK
I want the row of group of
ColumnA if ColumnB contain even 'NG'
row , select only one row which Column B = 'NG'
the result i want =
ColumnA Column B
1 NG
2 NG
3 OK
Thank you

That's some awful explanation, but I think this is what you were driving at:
DECLARE @forumTable TABLE (a INT, b CHAR(2))
INSERT INTO @forumTable (a, b)
VALUES
(1, 'OK'),(1, 'NG'),
(2, 'NG'),(2, 'NG'),
(3, 'OK'),(3, 'OK')
SELECT f.a, MIN(COALESCE(f2.b,f.b)) AS b
FROM @forumTable f
LEFT OUTER JOIN @forumTable f2
ON f.a = f2.a
AND f.b <> f2.b
GROUP BY f.a

Deleting Multiple Rows From Multiple Tables As an APEX Process

Hi There,
I'm interesting in hearing best practice approaches for deleting multiple rows from multiple tables from a single button click in an APEX application. I'm using 3.0.1.008
On my APEX page I have a Select list displaying all the Payments made and a user can view individual payments by selecting a Payment from the Select List (individual items are displayed below using Text Field (Disabled, saves state) items with a source of Database Column).
A Payment is to be deleted by selecting a custom image (Delete Payments Button) displayed in a Vertical Images List on the same page. The Target is set as the same page and I gave the Request a name of DELETEPAY.
What I tried to implement was creating a Conditional Process On Submit - After Computations and Validations that has a source of a PL/SQL anonymous block as follows:
BEGIN
UPDATE tblDebitNotes d
SET d.Paid = 0
WHERE 1=1
AND d.DebitNoteID = :P7_DEBITNOTEID;
INSERT INTO tblDeletedPayments
( PaymentID,
DebitNoteID,
Amount,
Date_A,
SupplierRef,
Description
VALUES
( :P7_PAYMENTID,
:P7_DEBITNOTEID,
:P7_PAID,
SYSDATE,
:P7_SUPPLIERREF,
:P7_DESCRIPTION
DELETE FROM tblPayments
WHERE 1=1
AND PaymentID = :P7_PAYMENTID;
END;
The Condition Type used was Request = Expression 1 where Expression 1 had a value of DELETEPAY
However this process is not doing anything!! Any insights greatly appreciated.
Many thanks,
Gary.

...the "button" is using a page level Target,...
I'm not sure what that means. If the target is specified in the definition of a list item, then clicking on the image will simply redirect to that URL. You must cause the page to be submitted instead, perhaps by making the URL a reference to the javaScript doSubmit function that is part of the standard library shipped with Application Express. Take a look at a Standard Tab on a sample application and see how it submits the page using doSubmit() and emulate that.

Easy Question:Select many rows from a table and execute BAPI for these rows

Hi Experts,
I have created one WD project. The WD project fetches some records of backend using BAPI and displays in a table. I have to select some rows from the table and then execute BAPI for selected rows.
How I can select multiple records from the table and then execute another BAPI for selected rows.
Regards,
Gary

Hi,
In the Node which you binded to the table create one more attribute of type boolean.
For example your node is as below:
//Table Node
TableNode
> Att1
> Att2
> isSelected(boolean) - Newly created attribute for this requirement.
//Result Node contains the elements selected in TableNode
ResultNode
>Att1
>Att2
Now in the table create one more Column with Checkbox as tablecell editor. Now bind this boolean attribute to that check box.
Now in the code you can get the selected rows by user as below:
for(int i=0;i<TableNode().size();i++)
if(wdContext.nodeTableNode().getTableNodeElementAt(i).getIsSelected()==true)
    IPrivateTestView.IResultNode element=wdContext.createResultNodeElement();
    element.setAtt1(wdContext.nodeTableNode().getTableNodeElementAt(i).getAtt1());
    element.setAtt2(wdContext.nodeTableNode().getTableNodeElementAt(i).getAtt2());
   wdContext.nodeResultNode().addElement(element);

Welcome to the forum.
Besides GROUP BY you can use UNIQUE instead of DISTINCT as well, but that's probably not wanted here ;) , and the ROW_NUMBER() analytic:

Need of SQL query in selecting distinct values from two tables

hi,
I need a query for selecting distinct values from two tables with one condition.
for eg:
there are two tables a & b.
in table a there are values like age,sex,name,empno and in table b valuses are such as age,salary,DOJ,empno.
here what i need is with the help of empno as unique field,i need to select distinct values from two tables (ie) except age.
can anybody please help me.
Thanks in advance,
Ratheesh

Not sure what you mean either, but perhaps this will start a dialog:
SELECT DISTINCT a.empno,
                a.name,
                a.sex,
                b.salary,
                b.doj
FROM    a,
        b
WHERE   a.empno = b.empno;Greg

Select a row from a table and throw an url

Hi experts,
I'm trying to select a row from a table in Visual Composer. What I need to do it's to click over this row and throw an Url. At the moment, I've added a column with a Pushbutton with the formula to show the link; it works fine. But I need to do it without buttons just selecting the row.
Is there anyboby who knows about that?
Thanks a lot.
Belen

Hi
To do this you will have to use a data store and a guard condition on the line which is triggered by the select action. You need to store a value in the data store each time a select action is performed. The guard condition should check for this and only perform the action when the value in the data store is greater than 0.

Select unique rows from two tables...

Hi,
I have two tables, replies1 and replies2.
SQL> desc replies
Name Null? Type
URN VARCHAR2(36)
ADDRESS VARCHAR2(18)
FILESIZE NUMBER
AS_NUM VARCHAR2(6)
SQL> desc replies2
Name Null? Type
URN VARCHAR2(36)
ADDRESS VARCHAR2(18)
AS_NUM VARCHAR2(6)
Both of the tables have no primary keys, but I have indixes on (urn, addrss) combination on both....
I am trying to select the unique rows with (urn, address) from replies2, and then find the matching size from replies...
I am using the following query:
select distinct replies2.urn, replies2.address, replies.filesize from replies2, replies where replies2.AS_NUM like 'XYZ' and replies.urn = replies2.urn;
I cannot figure out why it won't work. the way I understand it is that, distinct will give all distinct combination of all column names that follow, which is what I want...
I know it is wrong, because the query:
select count(*) from replies2 where AS_NUM like 'XYZ' returns less number of rows than the above query.
Any help would be greatly appreciated.
Thank you
Oz.

Thanks a lot Mohan for your reply.
urn is not a unique key. Several rows could have the same (urn, address) pair in both tables. What I want is retrieve all (urn, address) rows from one table, and find the size from the other table to make a (urn, address, size). I want all unique combinations of (urn, address) to appear in the output.
AS_NUM is an empty column in replies... It would've been a lot easier if it wasn't, since then I'll just say: select distinct urn, address, filesize from replies where AS_NUM like 'XYZ';
I will try your query though and let u know how it goes. It takes quite a while to run since my tables are huge.

SQL Server Store Procedure, selecting rows from multiple tables

i have got a store procedure that is pulling data from one table, now i have got the same data collected in a different table,
as the IDs are different i cannot put all data from the second table into the first one. so now i have to have two select statements in one store procedure. Although the corresponding data is same but the field names in both table are different. for instance
BRIEF_TITLE would be briefTitle in the second table. how can i merge the data from two different tables into one. the result is bonded to ASP.net grid view control.

>> I have a store procedure that is pulling data from one table, now I have got the same data collected in a different table, as the IDs are different I cannot put all data from the second table into the first one. <<
This is redundancy. The idea of databases even before RDBMS, was to remove redundancy. Oh, columns are not fields. These are basic concepts.
>> so now I have to have two select statements in one store procedure. Although the corresponding data is same but the field [sic] names in both table are different.<<
NO! Where is your data dictionary that assures data elements have one and only one name everywhere in the enterprise! You are is serious trouble here. The data element names should be universal and used everywhere with the same casing, so that case sensitive
standards will work.
>> for instance BRIEF_TITLE would be briefTitle in the second table.<<
The quick kludge is a VIEW with the ISO-11179 names over the camelCase crap
The moron who did the second table does not know ISO-11179 Standards and missed the research that showed us that camelCase does not work. Your eye is trained to jump to an Uppercase letter since it is the start of a semantic unit (proper name, sentence, paragraph,
emphasis, etc). When we researched this stuff at AIRMICS, this could add 8-12% to the time to maintain code in large systems. Your eyes twitch!
You really need to get your act together with a good text editor/ pretty printer tools. Get a copy of my SQL Programming Style and adapt it to those tools.
>> The result is bonded to ASP.net grid view control. <<

Perhaps
select distinct a.x,a.y,c.idboleta
from industriaego a,
       cops.analisis b,
       analisisboleta c
where a.nit = b.nit
   and a.correlaigeo = b.correlaigeo
   and b.idanalisis = c.idanalisisRegards

How to fetch rows from multiple tables

I have a page with items from 3 tables. I need to populate these items with values from the database. The page does not allow me to use multiple automated fetches. So instead I decided to use a pl/sql page process that runs a cursor to get my field values and the uses apex_util.set_session_state to set the field item values. IS there any isues with doing this? Is there a better way?

These tables are not really related so I gues I will stick with the pl/sql to populate and then page process to insert/update/delete. Here is the code I'm using.

Remove a row from multiple tables

Hello,
I have a form that has what appears to be one table. Since I needed 30 columns (29 of them are single character fields) I had to use 2 table objects. Then I needed the ability to add and remove rows. Adding a row at the end is easy enough. Deleting a specific row is the problem. At the moment, I added a third table which has a header row and a item body row. the body row is a button with the intention of removing that entire row from the large table. This means it needs to remove the row from all 3 tables.
My structure is:
form1
(Some other flowed subform that doesn't matter for us)
SubformPersonnel (a flowed subform)
SubformHeader (a positioned subform)
TextOverallHeader (text to label the oeverall 3 tables)
ButtonAddRow (adds a row to the end of all 3 tables)
SubformPersonnelTable (a positioned subform)
ContractorTableRemove (a table with 1 column for the Remove button)
HeaderRow (A hidden row to align the table with the other 2)
Item (A row with the Remove button)CellRemoveButton (the cell with the remove button and associated JavaScript)
ContractorTableLeft (a table with the left 15 printed columns)
HeaderRow
Contractor (A row of data to be removed when CellButton above is clicked)
ContractorTableRight (a table with the right 15 printed columns)
HeaderRow
Contractor (A row of data to be removed when CellButton above is clicked)
(Some other flowed subforms that I am not worried about at the moment)
The 3 tables are aligned so the headers all line up, with no spaces between them. The body rows then line up and this looks like one large table. From left to right, they are:
ContractorTableRemove, ContractorTableLeft, ContractorTableRight
So Item and Contractor rows are added when ButtonAddRow is clicked in the overall header. The intial count is set to 8 for each table, so I get 8 rows at startup. The minimum count is set to 1 for each. I know that each row of each table has the same index number because I filled those into a cell in each table durig the cell's initialize. This line, in the CellRemoveButton's click event deletes that cell's row in that table:
this.parent.parent._Item.removeInstance(this.parent.index);
I have tried all sorts of ways to delete the same row (using same index #) in the other 2 tables: ContractorTableLeft and ContractorTableRight, but don't seem to be getting the correct syntax correct. I have tried hard coding the references, using .parent as shown below, and also tried using an index of 1 just to try deleting a row with no results.
     this.parent.parent.parent.ContractorTableLeft._Contractor.removeInstance(this.parent.inde x);
Can someone get me the correct syntax here?
I have seen examples of putting a hidden delete button on each table and clicking that, but I am concerned that it will get in the way of the tables on either side of the table it is in. I reeally want to just reference the row and remove it so I can avoid any problems these additional delete problems may cause.
I have copied the form to https://acrobat.com/#d=7M8R50rEHf4AaVXppwyKLw

Thank you, Niall. Much appreciated!
The Delete button was more to make sure one could delete these outside a button in the actual row and I see I had the index wrong such that I was deleting the second row and not the first. I had toyed with using this as a hidden button if I could pass the index to the event's function.
I had not thought of adding the reference to each row as a variable. It seems to work very well.
For future reference to others, here is the code from the cellRemoveButton click event:
     // Declare some variables
     var i = this.parent.index;
     var oContractorLeft = ContractorTableLeft.Contractor;
     var oContractorRight = ContractorTableRight.Contractor;
     // Remove this row by accessing its index within the set of 'Item' row instances of the parent table
     _Item.removeInstance(i);
      // Since this table is actually 3 tables, we need to remove the other two table's instances as well.
     // Their index should be the same, so we just need to get their names correct.
     oContractorLeft.instanceManager.removeInstance(i);
     oContractorRight.instanceManager.removeInstance(i);
      // removing the row doesn't trigger calculations in tables in the form's current target (fixed in later versions of Acrobat)
     // force calculations to fire so the ItemIndex field's value is updated according to the remaining row's indexes
     // see http://forms.stefcameron.com/2006/05/20/add-recalculate/
     xfa.form.recalculate(1);
Again, thank you!
Karl
