Select tables which have only one row....

Hi Guys,
Can you tell me if there is a way to fetch all the tables in the database with only one record?
This is to filter out only the basic data tables in our application which consist of over 30,000 tables...
Many Thanks...

if your object statistics are accurate then you can use:
select * from dba_tables where num_rows = 1;Edited by: Martin Preiss on May 2, 2013 3:00 PM

Why a table can have only one PK ?

Just wanted to know the reason why Oracle allows only one PK per table ?
I came across a situation where my existing large PK which is on a single (ID) column needs an alteration to add a new column (No).
ID column on which PK is based is now subjected to have duplication and that is the reason why i want to add a new column. The new column composition is not going to ensure uniqueness.
So, i need to create (alter) PK on two columns now.
It seems, in order to do that, i need to drop the existing PK and create a new one. Since this is a OLTP production database, business cannot afford to drop the existing pk.
When i tried to create a separate PK on two columns, Oracle gave me below err:
ORA-02260: table can have only one primary keySo, i wanted to understand why Oracle allows only one PK / table ? and considering above err, is there any way to make required changes to my PK without altering existing PK?
(Table is a large 30 GB partition table and PK is a non partitioned global index)
I think PROBABLY i need to drop existing PK and re-create the new one. But core intention for opening this thread is to know rational behind one pk/table concept.

It's not exactly Oracle's fault. The ISO SQL standard requires that a "PRIMARY KEY" constraint can only be used once per table. However, a UNIQUE constraint on non-nullable columns achieves effectively the same thing as a PRIMARY KEY. You can have multiple UNIQUE constraints.
Arguably the PRIMARY KEY constraint is unnecessary and could safely be dropped from the SQL language. In principle in the relational model a "primary" key is nothing more or less than a candidate key. All keys are equal in the relational model and there is no fundamental reason to designate a primary key at all. There is certainly no reason not to have multiple keys. In the SQL world though it is a very widely observed convention to use a PRIMARY KEY constraint for each table and to use it for all foreign key references.

Issue with Selection Listener when the table has only one row

Hi All ,
I have developed a table in which I am using Selection Listener to perform some task when any row is selected.
It is working fine when I have more than 1 row in the table, but when I have only one row in the table , the selection listener do not call the corresponding method in bean.
I understand that selection event will be raised only when the row is changed, but in the use case when only one row is there, what should be done to make the selection listener work ?
In the selection listener I have written code to make the selected row as current row , and perform the required task.
Please suggest a way out for this situation.
Thanks in advance.

Hi,

How to restrict only one row in Table ??.

Hi all,
i want to restrict no. of rows to one,
that is not more that one row should be there in the table.
Following trigger works well in all conditions
except:
insert into myTab select 'x' from emp;
inserts 14 rows.
Create or replace trigger one_row_myTab
before insert on myTab
for each row
declare
cnt number;
pragma AUTONOMOUS_TRANSACTION;
Begin
select count(*) into cnt from mydual;
if cnt=1 then
raise_application_error(-20001,'MyDual Can have only one Row');
end if;
end;
i think with trigger it w't be possible because,
same transaction triggers c't query the table (Mutating Table),
Autonomus trans ca't identify uncommited changes.
pls add your suggestions.
Thanks for Reading the Post.

Merge only one row out of multiple rows

I need to prepare a merge statement which merge only one row in to a table. Below is the table definition, sample data and merge statement i used.
      CREATE TABLE Mob_Attr (NAME VARCHAR2(20), ATTR_1 VARCHAR2(20), ATTR_2 VARCHAR2(20), ATTR_3 VARCHAR2(20));
      CREATE TABLE Mob_Desc (NAME VARCHAR2(50), ATTR_1 VARCHAR2(20), ID NUMBER(20));
      CREATE TABLE Mob_Main (NAME VARCHAR2(20), ATTR VARCHAR2(20), ID VARCHAR2(10));
      insert into Mob_Attr(name, attr_1, attr_2,attr_3) values ('n1','aa',null,null);
      insert into Mob_Attr(name, attr_1, attr_2,attr_3) values ('n2','bb',null,null);
      insert into Mob_Attr(name, attr_1, attr_2,attr_3) values ('n3','cc',null,null);
      insert into Mob_Attr(name, attr_1, attr_2,attr_3) values ('n4','dd',null,null);
      insert into Mob_Desc (NAME,ATTR_1,ID) values ('n1','aa',10);
      insert into Mob_Desc (NAME,ATTR_1,ID) values ('n1','aa',15);
      insert into Mob_Desc (NAME,ATTR_1,ID) values ('n1','aa',123);
      insert into Mob_Desc (NAME,ATTR_1,ID) values ('n1','aa',1455);
      insert into Mob_Desc (NAME,ATTR_1,ID) values ('n2','bb',455);
      insert into Mob_Desc (NAME,ATTR_1,ID) values ('n2','bb',135);
      insert into Mob_Desc (NAME,ATTR_1,ID) values ('n3','cc',15);
      insert into Mob_Desc (NAME,ATTR_1,ID) values ('n3','cc',52);
      insert into Mob_Desc (NAME,ATTR_1,ID) values ('n4','dd',1455);
      merge into Mob_Main ma using
      (select d.name, d.attr_1,d.id from Mob_Attr a, Mob_Desc d
      where a.name = d.name and a.attr_1 = d.attr_1
      ) q on (ma.name=q.name and ma.attr=q.attr_1)
      when not matched then
      insert (NAME,ATTR,ID)
      values (q.name,q.attr_1,q.ID);
      Above merge statement will actually merge entire data . But i want the first row will only get inserted to the base table (Mob_Main). If we take name 'n1' first row from table Mob_Desc with ID as '10' only should get inserted. I can go for a cursor to do this as i have huge data volume i prefer merge instead.

MERGE INTO Mob_Main ma
     USING (SELECT d.name, d.attr_1, d.id
              FROM Mob_Attr a, Mob_Desc d
             WHERE a.name = d.name AND a.attr_1 = d.attr_1 AND id = 10
            UNION
            SELECT d.name, d.attr_1, d.id
              FROM Mob_Attr a, Mob_Desc d
             WHERE a.name = d.name AND a.attr_1 = d.attr_1 AND id != 10
                   AND NOT EXISTS
                              (SELECT 1
                                 FROM Mob_Desc d1
                                WHERE     d.name = d1.name
                                      AND d.attr_1 = d1.attr_1
                                      AND d1.id = 10)) q
        ON (ma.name = q.name AND ma.attr = q.attr_1)
WHEN NOT MATCHED
THEN
   INSERT     (NAME, ATTR, ID)
       VALUES (q.name, q.attr_1, q.ID);
COMMIT;
select *

Select event not triggered in table with only one row

Hi all,
I am building a BI VC application where query data is displayed in a table. When the user clicks on a table row another query is then triggered and output in a second table. The output from table 1 is linked to the input of query2/table2 with a select event.
The problem that I am facing is that if there is only one row in table 1, the select event is never triggered. If, however there are two or more rows in the table the select event is triggered and query 2 is executed. I have searched the forums but all I could find on select event problems was how to avoid the initial select event.
Has anyone else experienced this issue and what is the workaround or is this a bug in Visual Composer? We are on VC 7.0 SP19.
Cheers,
Astein Meland

Thanks Chittya,
Yes we have considered this option as well. But as we have more than one table linked together we would like to avoid having to manually click several buttons.
In the end I found Note 1364334 describing bugfixes released in VC 7.0 SP20:
"Normally, when a Visual Composer table is populated from a data service, the first row is selected by default. However, we have found that if only one data row is returned from the data service, this row is not selected by default and cannot be manually selected by clicking on it either."
So I think we will just have to upgrade our Portal to the latest support packs to solve this problem.
Thanks,
Astein

SQL Server 2012 Undetected Deadlock in a table with only one row

We have migrated our SQL 2000 Enterprise Database to SQL 2012 Enterprise few days ago.
This is our main database, so most of the applications access it.
The day after the migration, when users started to run tasks, the database access started to experiment a total failure.
That is, all processes in the SQL 2k12 database were in lock with each other. This is a commom case of deadlock, but the Database Engine was unable to detect it.
After some research, we found that the applications were trying to access a very simple table with only one row. This table has a number that is restarted every day and is used to number all the transactions made against the system. So, client
applications start a new transaction, get the current number, increment it by one and commit the transaction.
The only solution we found was to kill all user processes in SQL Server every time this situation occurs (no more than 5 minutes when all clients are accessing the database).
No client application was changed in this migration and this process was working very well for the last 10 years.
The problem is that SQL 2k12 is unable to handle this situation compared to SQL 2k.
It seems to occurs with other tables too, but as this is an "entry table" the problem occurs with it first.
I have searched internet and some suggest some workarounds like using table hints to completely lock the table at the begining of the transaction, but it can't be used to other tables.
Does anyone have heard this to be a problem with SQL 2k12? Is there any fixes to make SQL 2k12 as good as SQL 2k?

First off re: "Unfortunatelly, this can't be used in production environment as exclusive table lock would serialize the accesses to tables and there will be other tables that will suffer with this problem."
This is incorrect.
Using a table to generate sequence numbers like this is a bad idea exactly because the access must be serialized. Since you can't switch to a SEQUENCE object, which is the correct solution, the _entire goal_ of this exercise to find a way to properly
serialize access to this table. Using exclusive locking will not be necessary for all the tables; just for the single-row table used for generating sequence values with a cursor.
I converted the sample program to VB.NET:
Public Class Form1
Private mbCancel As Boolean = False
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim soConn As ADODB.Connection
Dim soRst As ADODB.Recordset
Dim sdData As Date
Dim slValue As Long
Dim slDelay As Long
'create database vbtest
'go
' CREATE TABLE [dbo].[ControlNumTest](
' [UltData] [datetime] NOT NULL,
' [UltNum] [int] NOT NULL,
' CONSTRAINT [PK_CorreioNumTeste] PRIMARY KEY CLUSTERED
' [UltData] Asc
' )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, FILLFACTOR = 80) ON [PRIMARY]
' ) ON [PRIMARY]
mbCancel = False
Do
' Configure the Connection object
soConn = New ADODB.Connection
With soConn
.ConnectionString = "Provider=SQLNCLI11;Initial Catalog=vbtest;Data Source=localhost;trusted_connection=yes"
.IsolationLevel = ADODB.IsolationLevelEnum.adXactCursorStability
.Mode = ADODB.ConnectModeEnum.adModeReadWrite
.CursorLocation = ADODB.CursorLocationEnum.adUseServer
.Open()
End With
' Start a new transaction
Call soConn.BeginTrans()
' Configure the RecordSet object
soRst = New ADODB.Recordset
With soRst
.ActiveConnection = soConn
.CursorLocation = ADODB.CursorLocationEnum.adUseServer
.CursorType = ADODB.CursorTypeEnum.adOpenForwardOnly
.LockType = ADODB.LockTypeEnum.adLockPessimistic
.Open("SELECT * FROM dbo.ControlNumTest")
End With
With soRst
sdData = .Fields!UltData.Value ' Read the last Date (LOCK INFO 1: See comments bello
slValue = .Fields!UltNum.Value ' Read the last Number
If sdData <> Date.Now.Date Then ' Date has changed?
sdData = Date.Now.Date
slValue = 1 ' Restart number
End If
.Fields!UltData.Value = sdData ' Update data
.Fields!UltNum.Value = slValue + 1 ' Next number
End With
Call soRst.Update()
Call soRst.Close()
' Ends the transaction
Call soConn.CommitTrans()
Call soConn.Close()
soRst = Nothing
soConn = Nothing
txtUltNum.Text = slValue + 1 ' Display the last number
Application.DoEvents()
slDelay = Int(((Rnd * 250) + 100) / 100) * 100
System.Threading.Thread.Sleep(slDelay)
Loop While mbCancel = False
If mbCancel = True Then
Call MsgBox("The test was canceled")
End If
Exit Sub
End Sub
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
mbCancel = True
End Sub
End Class
And created the table
CREATE TABLE [dbo].[ControlNumTest](
[UltData] [datetime] NOT NULL,
[UltNum] [int] NOT NULL,
CONSTRAINT [PK_CorreioNumTeste] PRIMARY KEY CLUSTERED
[UltData] Asc
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = on, FILLFACTOR = 80) ON [PRIMARY]
) ON [PRIMARY]
go insert into ControlNumTest values (cast(getdate()as date),1)
Then ran 3 copies of the program and generated the deadlock:

It's the S lock that comes from the cursor read that's the villian here. U locks are compatible with S locks, so one session gets a U lock and another gets an S lock. But then the session with an S needs a U, and the session with a U needs an
X. Deadlock.
I'm not sure what kind of locks were taken by this cursor code on SQL 2000, but on SQL 2012, this code is absolutely broken and should deadlock.
The right way to fix this code is to add (UPDLOCK,SERIALIZABLE) to the cursor
.Open("SELECT * FROM dbo.ControlNumTest with (updlock,serializable)")
So each session reads the table with a restrictive lock, and you don't mix S, U and X locks in this transaction. This resolves the deadlock, but requires a code change.
I tried several things that didn't require a code, which did not resolve the deadlock;
1) setting ALLOW_ROW_LOCKS=OFF ALLOW_PAGE_LOCKS=OFF
2) SERIALIZABLE isolation level
3) Switching OleDB providers from SQLOLEDB to SQLNCLI11
Then I replaced the table with a view containing a lock hint:
CREATE TABLE [dbo].[ControlNumTest_t](
[UltData] [datetime] NOT NULL,
[UltNum] [int] NOT NULL,
CONSTRAINT [PK_CorreioNumTeste] PRIMARY KEY CLUSTERED
[UltData] Asc
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = on, FILLFACTOR = 80) ON [PRIMARY]
) ON [PRIMARY]
go
create view ControlNumTest as
select * from ControlNumTest_t with (tablockx)
Which, at least in my limited testing, resovlved the deadlock without any client code change.

Selecting only one row at a time

Hi experts,
i have following doubt regarding selecting rows from a db:
Is there any way of selecting only one row AT A TIME from a dabase just to collect the data in rows instead of in a unique document containing all the rows?
I would like you to ellaborate on this as i need to send only one row to the IE, and then other row, and so on... without throwing any error!
I have seen that there are SELECT SINGLE and SELECT UP TO 1 ROW, but these two methods are only useful when retrieving only one row, and that does not match my requirements. I need to process all the rows but one by one..
I know that we can use the receiver jdbc adapter as if it was a sender by means of its specific datatype, but how to do it row by row??
Hope i had explained well..
Thanks in advance and best regards,
David

Hi kiran,
Yes, my table has 5 not null fields but i am selecting and updating fixes values so i think that I will definetely go for the next solution:
SELECT * FROM t1 WHERE status='0' and ROWNUM<2;
UPDATE t1 SET status='1' WHERE status='0' and ROWNUM<2;
My only concern is if the update will take the same row that the select.... BTW, I think it will
..What do you guys think?
I ve been trying to operate with your proposed queries but i received some errors. Your queries are very interesting but i think that with the above ones i meet my requirements as the status field will be 0 for not processed rows and 1 for precessed ones (and the update will look for the row that meets the same 'where' clause than the select, and then, and only then, it will set status='1').
The only thing i have to care about is what i questioned before.
Thanks a lot and best regards,
David

Oracle database link to MySQL select only one row

Hello,
I have created a connection from the Oracle batabase 11.2 to a MySQL database via database link. The following statement shows, that 35 rows are in the mySQL table:
SQL> select count(*) from "main_pages"@MOREWEB;
COUNT(*)
        35
But a normal select statement only return 1 row.
SQL> select "subject" from "main_pages"@MOREWEB;

The DataDirect-ODBC-driver is not possible, because we like to use the free MySQL-database an DataDirect only support the enterprise edition.
I also have tried to limit the HS_OPEN_CURSORS or dont limit the HS_FDS_FETCH_ROWS, but there is no difference in the result. I always get only one row.

Bianca,
If you log directly into MySQL and issue the same query (select "subject" from "main_pages";) what data is returned?
I looks to me that you count is the number of rows in the entire table "main_pages"
while you select is for the data in the "subject" column only.
This seems to indicate that you have just one row in that subject column.

WHAATT?
What do you mean by "just one row in that subject column"?
That makes no sense at all. A row is a row. A column is a part of a row. All rows have all columns, though not all columns of all rows will necessarily have an assigned value. Lacking a WHERE clause to filter rows, any SELECT should return all rows.

Same query canreturn rows in different order next time you run it unless you specify ORDER BY. Only ORDER BY guarantees order, so when you say first row/second row you must provide ordering criteria.

Only one row show in table with tablepopin

Hi,
I've a table with a tablecolum with a tablepopintogglecell, and a tablepopin.
I want that only one row show (when i press the togglelink if there is other row open, automatically close that row)

Hi,
you should implement the on toggle event,
you will have the importing context_element, so you know which one is triggered,
form your node, get_elements().
loop over the table where ne to context_element, clear the popin attribute,

Create a business model when we have only one source table

Hi,
How to create a business model when we have only one source table in Physical layer
Regards
Swathi

This is very much possible and feasible. Its called as Single Table model. Good example is SA System Subject Area where we just have a single physical source. No need to create Alias in Physical. Simply use the same table twice in BMM with one Logical Table as Dummy Fact..Like say Count of Users (aggregated). Then apply normal Complex join in BMM and present in presentation layer.
