Hi,
i would like to know how to lock a table from other to view when select statement..can anyone help me with that???
i tried
SELECT * FROM IMIS_FRAMEWORK_RUNNING_NUMBER with (HOLDLOCK,ROWLOCK)
WHERE running_type=@type;
but i m still able to see my row when i perform my SELECT STATEMENT from other query analyser..
Please help me with this..thank you
I open query analyser and on one tab I update a record in a transaction and hold it.
begin tran
update customers set territory = 'x' where customer = 'A00001'
--rollback tran
In a second tab I attempt to update all records in the table
update customers set carrier = ''
Clear this fails because of the lock placed during the first script and this is fine.
However, is there a way to get the 2nd script to ignore the locked rows and just update as many as it can? The obvious answer seemed to be the READPAST hint like follows…
update customers with (READPAST) set carrier = ''
…but this is still blocked by the original lock. I’ve tried combining it with all sorts of other table hints but all seem to get blocked.
The following does work, ignoring the lock and not returning the data
Select * from customers with (READPAST) where customer = 'A00001'
I’ve tried combining this with the update like so…
update customers
set carrier = ''
from customers with (READPAST)
where customer = 'A00001'
..but this is blocked too.
I’m so desperate I tried moving the update into a cursor and update one row at a time. Nothing worked. I thought I might be able to do something like this
If (Select count(*)
from customers with (READPAST)
where customer = 'A00001') > 0
--then perform update
..but this returns a value of 1 even though the following returns no rows.
Select * from customers with (READPAST) where customer = 'A00001'
I am using this SQL in a stored procedure:
INSERT INTO staff_address (staff_number, block_number, block_name) VALUES(@staff_number, @block_number, @block_name)
and I want to update the value @block_number from blocks database with:
SELECT * FROM blocks WHERE block_number = given_block_number
Import Hadoop Data into Analysis Services Tabular | Mentioned in the article is an example of using openquery to perform select statement on a Hive table through a linkedserver.
I was wondering how can i also perform an insert statement with openquery?
I understand that for example to insert into Hive is to use a Load command, like:
Code:
load data inpath '/tmp/data.csv' overwrite into table tableA;
How do i execute this with openquery? I've tried the example below and some slight variations but all I get in return were syntax errors
Code:
insert openquery (linkedserverName, 'load data inpath '/tmp/data.csv' overwrite into table tableA;')
I'm working with ADO 2.8 en C++ with Visual Studio 2005. I want to perform a "select" in asynchronous mode. I don't really understand the logical of the recordset events. For example, I received a number of MoveComplete event higher than the number of rows in my recordset. It is really not clear for me ...
Does someone knows where I can find a a good example of C++ (or VB) code to manage select statements in asynchronous mode ?
Thanks in advance for your help.

i just can't find a way to perform this Select Query in my ASP.Net page. I just want to find out the sales for a certain period[startDate - endDate] for each Region that will be selected in the checkbox. Table Sales Fields: SalesID | RegionID | Date | Amount This is how the interface looks like.Thank You.

I want to lock the record on select query so that no other user can update this record, is it possible and i want to unlock record when use stop view this record.
Anybody know how a SELECT statement can generate an exclusive lock on a table ?
I always thought that SELECT's take out shared locks. Is this something to do with temporary tables generated by ORDER BY's and DISTINCT ?
Rogue SQL below (from Site Server).
SELECT A.i_Dsid, A.i_Aid, A.vc_Val, A.i_Val, A.dt_Val, A.img_Val FROM Object_Attributes A, ( SELECT DISTINCT L.i_Dsid FROM Object_Lookup L , Object_Attributes OA2 (index = IND_vc_Aid) WHERE ((( L.i_ObjectClass = 9999 )) AND ( OA2.vc_Val LIKE ( '999999999.9999999%' ) AND OA2.i_Aid = 99)) AND (L.i_Container_Dsid = 99) AND ( OA2.i_Dsid = L.i_Dsid )) AS B WHERE B.i_Dsid = A.i_Dsid AND A.i_Aid NOT IN( 1, 2, 3, 4, 5 ) ORDER BY A.i_Dsid, A.i_Aid
Can anybody suggest a workaround ? Thanks.

Hi All,I have a database that is serving a web site with reasonably hightraffiic.We're getting errors at certain points where processes are beinglocked. In particular, one of our people has suggested that an updatestatement contained within a stored procedure that uses a wherecondition that only touches on a column that has a clustered primaryindex on it will still cause a table lock.So, for example:UPDATE ORDERS SETprod = @product,val = @valWHERE ordid = @ordidIn this case ordid has a clustered primary index on it.Can anyone tell me if this would be the case, and if there's a way ofensuring that we are only doing a row lock on the record specified inthe where condition?Many, many thanks in advance!Much warmth,Murray

I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian

Hi
We are facing an acute situation in our web-application. Technology is ASP.NEt/VB.NET, SQL Server 2000.
Consider a scenario in which User 1 is clicking on a button which calls a SQL stored procedure. This procedure selects Group A of records of Database Page1.
At the same time if User 2 also clicks the same button which calls same SQL stored procedure. This procedure selects Group B of records of Database Page1.
So, its the same Page1 but different sets of records. At this moment, both the calls have shared locked on the Page1 inside the procedure.
Now, in call 1, inside the procedure after selecting Group A of records, the next statement is and update to those records. As soon as update statement executes, SQL Server throws a deadlock exception as follows :
Transaction (Process ID 78) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction
We are able to understand why its happening. Its because, Group A and Group B of records are on the same Page1. But both the users have shared lock on the Page1. So, no one gets the exclusive lock in records for update, even though, the records are different.
How can I resolve this issue? How can I get lock on wanted rows instead of entire page?
Please advice. Thanks a bunch.

Hi,
I have set of 2 DTS packages, one of which calls the other by forming a command-line (dtexec) using a Execute Process task.
From the parent package-> Execute Process Task->
dtsexec /F etc... /<pkg variable> = "servername"
Each of the parent and the called package have a variable: "User::DWServerSQLInstance" which is mapped to the SQL server connection manager server name property using an expression. The outer package has the above variable and so does the inner called package (which gets assigned through the command line from the outerpackage call to inner)
I "sometimes" get the following error:

Hi All,
I have seen a few other people have this error.
Package works fine when run from BIDS, DTExec, dtexecui. When I schedule it, It get these random errors. (See below)
The main culprit is a variable called "RecordsetFileDIR" which is set using an expression. (@[User::_ROOT] + "RecordSets\")
A number of other variables use this as part of their expression and as they all fail, pretty much everything dies.
I have installed SP1 (Not Beta) on server. Package uses config files to set the value of _ROOT.
The error does not always seem to be with this particular variable though. Always a variable that uses an expression but errors are random. Also, It will run 3 out of 10 times without a problem. I am the only person on the server at the time.
Any ideas?
Cheers,
Crispin

I am using three tables in this query, one is events_detail, one is events_summary, the third if gifts. The original select statement counted the number of ids (event_details.id_number) that appear per event_name (event_summary.event_name).
Now, I would like to add in another column that counts the number of IDs that gave a gift who attended an event that were also listed in the event_ details table. So far I have come up with the following. My main issue is linking the subquery properly back to the main query. how to count in the sub-query and have the result placed within the groups results in the main query.
SELECT es.event_name, es.event_id, COUNT(ed.id_number) Number_Attendees,
(
SELECT COUNT(gifts.donor_id) AS Count2
FROM gifts
WHERE gifts.donor_id = ed.id_number
) subquery2

The coding I need is something like this: set implicit_transactions on begin transaction select * from table1 with (tablock, holdlock) update table2 set field1 = 'test' commit transaction commit transaction
I have tried the coding above, it won't prevent others from locking table1.
So, I changed the tablock to tablockx to prevent others from locking table1. But this will also prevent others from reading table1. So, how can I lock table1 so others cannot lock it but still able to read it?
Thank you for any help
Hi All,
Can some one point me in the right direction in how to construct my SQL query within my cursor?
I Have got a cursor which i am using to iterate through a table, What i am trying to do is in my statement(used to open the cursor) is compare 2 tables (the one which my cursor is iterating) to see if there is a matching row in the other table (using both tables ID's Like So:
SELECT column_List
FROM Table1
WHERE Table1_id = Table2_id
so for each row my cursor checks if there is a corresponding match in table2... but i would like to write to an error log
and do other statements if there is no match
how do i add this condition to my statement either using an if...else statement proceeding to the next row?
here is the statment i attempted to write:
SELECT column_List
FROM table1
WHERE
Table1_id = Table2.id
now i want to incoporate the statements below into the statement above as a condition when table1.id <> table2.id
IF table1.id <> table2.id
BEGIN
SET @DebugMessage = 'data not live.'
RAISERROR (@DebugMessage, 16, 1) WITH LOG
END
essentially what i am trying to sayin my statement is:
go to the first row
check if it has a match in table 2,
if there is no match execute a number of statements such as error loging e.t.c
go to the next row
repeat the previous statements
...i also looked through some Case...When statements am just not sure how to put in the condition
thanks in advance
I am a newbie to SQL. I have a table (AenComponent) with three columns (State1, State2, State3). Each column has a set of numeric values. I would like to get a number count from all of the rows that contain the value of 1, no matter which column they are in.
I have tried
SELECT COUNT(*) AS Expr1FROM AenComponentWHERE (State1 = 1) OR (State2 = 1) OR (State3 = 1)
but it does not give me an accurate count. Any help would be appreciated.
thanks
