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

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

) ON [PRIMARY]
go insert into ControlNumTest values (cast(getdate()as date),1)

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.

Number of Rows, displaying a table with only one row

Hello,
I am doing my first VC tests on the discovery System.
I have an input form where I put in the username, then choose a user from a table and with the user ID I want to show the user details in another table.
Now since I am only pickling one user, the new table will only have one row. In VC I cannot set the no. of rows to 1 though, since I cannot edit the no. of rows field. I also cannot disable the scroll buttons.
Why is that?
Is there another way to display user details? I tried to display it in read-only form, but it is pretty ugly.
Another question regarding designing in VC:
Are there any design elements in VC for example to group form fields that belong together? Let's say I have street name, number, postal code and so on, could I use a design element to group them under the label "Address" ?

Peter,
For some reason the No. of Rows and Scroll Buttons options are only available if your compiler is set to Web DynPro. Whenever you compile to Flash they're disabled.

Pages won't allow me to create a table with just one row.

I'm trying to create a one row, two colum table in Pages. I have no problem with the columns. But I cannot create the table with just one row. Two rows apppears to be the minimum. Any ideas??

In Pages 5.2, click the equal sign at bottom-left of table and reduce the row count to one.

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.

Problem with creating an dynamic internal table with only one field.

Hi,
i create an internal table like this:
FIELD-SYMBOLS: <GT_ITAB>      TYPE TABLE,
               <GS_ITAB>,
               <FS>.
DATA: GT_DATA TYPE REF TO DATA.
DATA: GS_DATA TYPE REF TO DATA.
DATA: TABNAME   LIKE DD03L-TABNAME.
DATA: FIELDNAME LIKE DD03L-FIELDNAME.
DATA: TBFDNAM   TYPE TBFDNAM VALUE 'LFA1-NAME1'.
SPLIT TBFDNAM AT '-' INTO TABNAME FIELDNAME.
CREATE DATA GT_DATA TYPE TABLE OF (TABNAME).
ASSIGN GT_DATA->* TO <GT_ITAB>.
CREATE DATA GS_DATA LIKE LINE OF <GT_ITAB>.
ASSIGN GS_DATA->* TO <GS_ITAB>.
SELECT * FROM (TABNAME) INTO CORRESPONDING FIELDS OF TABLE <GT_ITAB>.
BREAK-POINT.
it works OK.
Now i want to create an internal table not like LFA1 but with LFA1-NAME1 Field TBFDNAM.
It's not only LFA1-NAME1 it shell be the value of TBFDNAM.
When i change
CREATE DATA GT_DATA TYPE TABLE OF (TABNAME).
to
CREATE DATA GT_DATA TYPE TABLE OF ( TBFDNAM).
i get an shortdump.
Any idea?
Regards, Dieter

Hi Dieter,
Your approach is ok, but it will create dynamic table without a structure of NAME1. Only the line type will be suitable (but field name will not exists -> hence the error in the select statement).
In this case you need to create a dynamic table which structure consists of one field named NAME1.
This code is the appropriate one:
" your definitions
DATA: tabname LIKE dd03l-tabname.
DATA: fieldname LIKE dd03l-fieldname.
DATA: tbfdnam TYPE tbfdnam VALUE 'LFA1-NAME1'.
FIELD-SYMBOLS <gt_itab> TYPE table.
"new ones
DATA: it_fcat TYPE lvc_t_fcat WITH HEADER LINE.
DATA: gt_itab TYPE REF TO data.
" get table and fieldname
SPLIT tbfdnam AT '-' INTO tabname fieldname.
" create dynamic table with structure NAME1 (only one field)
it_fcat-fieldname = fieldname.
it_fcat-tabname = tabname.
APPEND it_fcat.
CALL METHOD cl_alv_table_create=>create_dynamic_table
EXPORTING
    it_fieldcatalog           = it_fcat[]
IMPORTING
    ep_table                  = gt_itab
EXCEPTIONS
    generate_subpool_dir_full = 1
    OTHERS                    = 2.
CHECK sy-subrc = 0.
" dereference table
ASSIGN gt_itab->* TO <gt_itab>.
" insert data only to NAME1 field
SELECT * FROM (tabname) INTO CORRESPONDING FIELDS OF TABLE <gt_itab>.
I checked, this works fine:)

Is it possible to make stored procedure which results with only one row?

Greetings community,
I’m making the app in .NET, and I don’t really have the problem to get the result, but through watching videos I’ve realized that using LINQ isn’t always the best way of doing things, because it requires pulling too much data through the
network to do some LINQ over it. There’s also the issue of security, so I was advised to use stored procedures and functions on SQL server to accomplish what I need without disturbing client machines too much.
I’m absolute beginner in TSQL, so I need your help. I need to extract last order of particular customer and I wonder if that could be accomplished. To make things simple, let’s imagine that my orders table has only these three columns:
OrderID (int, primary key, identity incremented), CustomerID (int), and DateOfOrder(datetime). I need a procedure that would take CustomerID as parameter, and return one single row which represent the last order of that customer.
I would also be very grateful to see the extended procedure that would take LastCount additional parameter and return several rows which would represent last several orders of that customer.
Last thing, if it’s not too much already, I would very appreciate some link to educational videos about SQL server for beginners. There were great videos on msdev.com, but this web address doesn’t exist anymore.

There are many tutorials on MSDN with Linq including SQL Server Express. A good start is this here:

Why DDL during SELECT is possible. Or why SELECT does not put a table lock?

This is a question to people who really knows Oracle internals or/and RDB theory.
(The question is relocated from another thread for not hijacking on that's original question.)
Why DDL during SELECT is possible? Or why SELECT does not put TM 2 Row Shared lock on table(s)?
This not locking causes a possibility while one session is running a long select, another can truncate and even drop table(s) that are being read by the first session.
I think, humbly assume, that Oracle does not put TM 2 lock on tables, that are being simply SELECTed, by some significant technical reason. But I do not know this reason. If somebody knows please shed a light.
Also, if you know that this behavior is totally correct from perspective of RDB theory, please explain me.
I'll try to explain my point.
It is a matter of data consistency and integrity that is supported in Oracle everywhere except this place.
a) If one session is reading data from moment T and other session changes data on its way at moment T1, the first session wont read that changed data, it will read the data that was there on moment T.
This is declared as Read Consistency principle.
b) If one session is changing data, and another session tries to truncate or drop table - the second session will fail with error ORA-00054: resource busy and acquire with NOWAIT specified.
This is declared as Data Integrity principle.
c) But why not to follow the above principles in case when one session reads data and another session tries to truncate or drop table (or do other DDL operations)?
It is counter-intuitive. Why not to put TM 2 (SS) lock during SELECT execution that would prevent DDLs on this table?
What I only can assume is that this is only because some technical difficulty or limitation.
What is this limitation or other reason in favor of which Oracle sacrificed consistency in this case?

Aman,
There was no need to clarify how DML lock works, I know that.
Also I know that in Oracle a Select does not lock neither table rows nor table itself.
The reason I mentioned it because you brought up the word change which is far better suited for DML's than DDL's as the former has a requirement to have its Undo preserved.
Again, my question was why Select does not protect itself by locking table(s), partitions and indexes?Protect from what? There is nothing wrong with doing a select. What would happen with a select doing a lock on the table before being executed in its entirety (forget DDL and DML altogether for a moment) ? State one good reason that there should be a lock for the select. If it has to, it would be always isn't it?
The keyword here is concurrency and that's what is the best when the number of locks obtained are lesser at non-required operations. A select doesn't change anything that's why in Oracle, there is no read-level lock.I am not saying about row locks while reading. They are not needed because Undo resolves concurrency.Only in the case of DML where the change is still active and the buffers are dirty. With a DDL, its an implicit commit.
I am asking why Select does not enqueue one, only one lock per object that participates in the Select?Again, my question back to you is, what good you would get from it? What purpose it would solve?
It is not very expensive, I suppose. But it would protect from DDLs that can destroy the Select's result set. You have seen in your system and in my demo(and that's what the the question was on the other thread also) that the result remains intact and its not a behavior from now. Its the same since the time I have started learning Oracle. Can you explain that why you think that the result of select statement would be wrong for a drop table? I believe, its been stated repeatedly that if the select has no requirement to look back the table, it would get completed. Only if the select needs to access the table again, it would fail. So even if we consider your explanation, there is no wrong result shown at all. Once the session encounters that the table is dropped for the statement, the execution stops right away. So where is the destroyed result?
Yes, it is less dangerous when Select does not lock table comparing with what would happen with DMLs in such case (that is why DMLs protect themselves by TM 3), it affects only the Select and its consumer, but still ... I don't understand this Oracle's decision. What is a reasoning behind it?.As I said, to improve concurrency.
Aman....

Select tables which have only one row....

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...

Counting (interneal timebase)events with only one counter

Hello,
i am using a PXI-6115 card. This card is external clocked with 8 MHz. But I want to measure only about every second. So I divided the external clock with the internal counter 0. This works fine.
Now my problem. Now I want to know the external clock rate. Is it possible to build a pulse period measurement with only one counter??
I thinking of counting internal timebase- pulses with counter 1 and to start and stop the counter 1 by the output of counter 0.
Is this possible and how??
Thanks for help, Ruediger

Yes, there's a way to measure pulse periods with a single counter. The trick is to perform a buffered period measurement and sum the periods. The size of the buffer will determine the quantization/roundoff error.
The source of this error is that you have no control over the initial phase relationship of your external clock and your internal timebase. There's a nominal ratio between the two frequencies, and you'd start by expecting ratio * (buffer size) total cycles counted.
However, your actual count must be an integer, so you'll get either the next-highest or next-lowest integer, but you can't predict or control which one.
Example: If you collect 1 period at 8 MHz using the internal 20 MHz timebase, you'll capture either 2 or 3 e
dges from your timebase, implying a measured frequency of either 10 MHz or 6.6667 MHz.
If you collect 1001 periods, you'll capture a total of 2502 or 2503 timebase edges, implying a measured frequency of either 8.0016 MHz or 7.9984 MHz.
Notes:
1. In many cases, you can set up for buffered event counting, using the internal 20 MHz clock as a source and your external 8 MHz as a gate.
The advantage is that the buffered values already represent cumulative time so you don't need to sum them.
A disadvantage would be that the internal 24-bit counter value will roll-over in less than 1 second at 20 MHz. I typically capture periods and then sum in software because I can convert to floating point between capture and sum if necessary to produce both high-resolution and long duration measurements.
2. You should typically ignore the very first value in the buffer and work only with the others. If you want to capture 1001 legitimate periods, size the buffer for at least 1002

Multiple events per date with only one photo each - Unwanted

I have the eyefi wireless sd card in my camera and it is setup to transmit my photos into iphoto automatically, which it does. However, the problem arises in that iphoto creates multiple events for the same date each containing only one photo. I would prefer that iphoto create individual events per date and have the multiples of that date's photos within. I thought I had the settings configured to do so as I have preferences set for autosplit events one per day but I still see events such as - July 3, 2008 - July 3, 2008 - July 3, 2008 - each with only one photo inside.
I am wondering if it is something in iphoto's settings or the way in which eyefi transmits the photos into iphoto.
Any thoughts?

I do not have a WiFi connection to my camera so can not test but am just guessing
I can think of two possibilities
- 1 - if you are taking the photos with the WiFi connected then each time you snap a photo it may be being sent which would be looked at as a new import and therefore create a new event - to stop this I believe you would have to not have a full time WiFi connection to your camera or somehow set the camera to send batched - not each one - iPhoto will take each batch into and follow the rules for making events for that batch even if you camera is sending many batches of One photo
- 2 - You have the preference for making batches set to one every two hours and there is a long time between photos - I'm guessing that #1 is more likely

Support for triggers for tables with clustered column-store indexes

Hello,
We are very excited about the new clustered column-store indexes in SQL 2014 and our performance tests shows significant performance gains. However, our existing functionality relies on triggers and they are not allowed on tables with column-store
indexes. Does anybody have information as to whether allowing triggers on tables with column-store indexes is anywhere on the radar?
Thank you!
P.S. We spent a lot of time considering various work-around to avoid triggers, but the amount of work we would have to do is simply overwhelming, so we are considering delaying our upgrade until such functionality hopefully becomes available.

My gut reaction is that this restriction is likely to remain for the forseeable future. Columnstore indexes are intended for data warehouses, and while I don't do data warehouses myself, I cannot say that a fact table is where I expect to find a trigger.
But if you think that there is a good business case for permitting triggers on columnstore tables, submit a suggestion on

Note that if you give some business-oriented explantion why this is a great benefit, it is more likely that Microsoft is likely to listen.

When i try to sync photos from iPhoto to my iPad using iTunes, the "Selected Folders" option is greyed out with only the "All Folders" option available, how do i change this?

When i try to sync photos from iPhoto to my iPad using iTunes, the "Selected Folders" option is greyed out with only the "All Folders" option available, how do i change this?

I add the keyword 'sync' to any photos I want added to the iPhone/iPad.
Then, during the regular process of syncing the iPhone/iPad with my computer (mac), the photos with that keyword would be copied onto the iPhone, iPad.
I've been doing it this way ever since I was shown how to; ie after I got my iPhone 2 years ago. And every time the process worked - until the last few weeks. Suddenly it doesn't do it any more.
I believe I have upgraded software (either iTunes or iPhoto or both) during this period. I try to keep my software updated but have noticed previously that the new version often is disappointing.
I've not tended to use Smart albums much.
