As in title. Is there any tool? I'm asking beceuse, I have some big bases, and processing may take a lot of time (at least few hours), and I'll be glad if it's possibility to know estimate time before query runs. I'm using MsSql 2005 Developer edition.
View 14 RepliesI am running an update query.It is taking long time. To find the estimated completion time i checked sys.dm_exec_request or sys.dm_exec_session or sp_who2 but there is no clue. It is showing as zero.
View 3 Replies View RelatedI have a ordersystem with repeating orders. Each order has a orderline
with a frequency and a intervaltype (day, week, month and so on) for
indicating how often a task should be done.
When an task/job is done, an equivalent receipt with receiptlines is
generated.
When a new job/task should be suggested, it has to calculate the
shortest next intervallength for each repeating orderline. This
intervallength must then be added to the date of the last receiptline.
I want to to this all in a SPROC. My result should be the one next
orderline that should be carried out with a date for when this is.

This is what I did
dbcc checkdb ('mydatabase', REPAIR_REBUILD) with estimateonly
It gave me error ....
estimateonly is not an option.
What did I do wrong? Thank you for your help!!!!!!!!!!
I have a 2.5TB database that we need to run checkdb on. Is there a formula to figure how log it would take with no options? Doing research, it appears the we are stuck with doing the PHYSICAL_ONLY due to time constraints.

View 2 Replies View RelatedWe are running a SQL Server 2008R2 64-bit database system on a Windows 2012 R2 64-bit Standard system. I have noticed in recent weeks that our differential backups periodically are taking longer than expected to complete. The usual amount of time is about one hour, but on several occasions, it has taken upwards to five hours. The nights when the job takes longer to complete are on Friday.
I did some checking online, and one possible reason for this issue is my scheduling the reindexing of the database on the morning of the Differential backup. For example, this past Friday the reindexing occurred at 1:00 AM with the Differential running at 10:00 PM that night.The article that I read suggested the reindexing, which takes several minutes, if that, to complete, should be scheduled to run just before the Full backup job.
Hi,
I have a big table and want to make a plausibility check of it´s data.
Problem is, that my query stops, if there is an unexpected datatype in one of the rows. But that is it, what i want to filter out of my table with that query and save the result as new correct table.
How can i write a parameter to my query SQL Code, that if a error occurs, the querry resumes and the error line will not displayed in my final querry overview?
In my books and on the net, i don´t found something to this theme ;-(.
Thx in advance.
Hello--I do not know if this group can help me with SQL Server Reporting Services ... but here it goes. I have a report built on a query and I want to be able to send a parameter (@theWhere) that is a string which is a where clause "(MEGLOMART_TYP_CODE <> 'XYZ' AND MEGLOMART_STAFF_SHORTAGE > 25)" these strings can vary depending on what columns the user selects and what operators they want to use. Generation of proper SQL for the where clause has been verified, I just need to be able to pass these, is there any way to do this...see example query below and how I was planning on using the @theWhere variable...

I'll try to explain what is happening the best I can:
We have a server running Windows Advanced Server 2000 (SP4) w/ SQL
server 2000 (SP3) (from now on Server A). I have a publication on this
machine with dynamic filters (Changing the HOST_NAME()). The
publication is sending the snapshots to another machine (desktop
machine). The Mobile agent is in the same machine as the snapshots.
The mobile application is syncing fine when hitting Server A. The sync
is done Asynchronously.
Then we have Server B. Running Windows Server 2003 (SP1) w/ SQL 2000
(SP4), same publication w/ dynamic filter however the snapshots and the
mobile agent are in this server.
The mobile application will sync the 1st time but any subsequent syncs
will not work. I check on the Replication monitor and it tells me that
the Merge was a success but the mobile application will not execute the
download table callback, it will execute the Sync callback 5 times and
not proceed in executing the download table callback.
If I change the configuration on the mobile app to point to Server A
the sync will work just fine but, if I change it back to Server B the
sync will work once then it will stop working.
Anyone have some suggestions for troubleshooting?

"I wonder why the boolean values Set to "Disable Property" using expressions does not work as expected (though Precedence constraints work fine). I find no way to disable individual task. "
I have a boolen variable V, (False) enabled by default at design time for a task T, I disable T based on a condition (if A ! = 'a') during runtime.
Now first time when I run the Package, Task gets disabled (works fine on the condition given). However T gets permanently disabled even after we stop debug mode, which is not the expected behavior. Further on when you run, it wont work at all.
Is it true that a task disabled at design time cannot be enabled during runtime via expressions ?
If things are working fine in your case, pls let me know what settings are required.

I have a table that stores working hrs, such as
RecID,StaffID,StartDate,EndDate
17,969,2015-05-18 00:00:00.000,2015-05-18 06:00:00.000
18,969,2015-05-18 18:00:00.000,2015-05-19 06:00:00.000

24,969,2015-05-24 22:00:00.000,2015-05-25 00:00:00.000
So working times can go over midnight, there can be more than one working period in a day etc.
For this staff member the summary of the weeks work will be
18/05/2015 - 12 hrs
19/05/2015 - 12 hrs
20/05/2015 - 12 hrs
21/05/2015 - 12 hrs
22/05/2015 - 12 hrs
23/05/2015 - 16 hrs
24/05/2015 - 10 hrs
Now for the complicated part, a person can take absence(sick,holiday,other) for any part of a day or whole day(s). For these absence periods only the worked time on that day needs to be negated off, not the whole period of time.
So for example
If this person
had a days holiday on the 22nd, shown in the HOLIDAY table as
StaffID,DateFrom, DateTo
969, 22/05/2015 00:00:00.000,22/05/2015 23:59:59.000
A Leave of Absence on the 20th, shown in the LEAVE table as
StaffID,DateFrom, DateTo
969,20/05/2015 12:00:00.000,20/05/2015 16:00:00.000
And was off sick on the morning of the 19th, shown in the SICKNESS Table as
StaffID,DateFrom, DateTo
969, 19/05/2015 00:00:00.000,19/05/2015 11:59:59.000
Now the Summary table should now show
18/05/2015 - 12 hrs
19/05/2015 - 6 hrs
20/05/2015 - 12 hrs
21/05/2015 - 12 hrs
22/05/2015 - 0 hrs
23/05/2015 - 16 hrs
24/05/2015 - 10 hrs
The 'Leave of Absence' on the 20th had no effect on the total for the day as it was between planned work times. how to do this within T-SQL, as simple as possible as I've got to had this code over to other staff members to maintain, who have not had much SQL experience yet?
I've tried doing it as a temp table, with dual insert/select commands, splitting the times over midnight, which partially worked but missed some of the combinations.
how long does it take to convert a DTS package to ssis package?

Hi,
I have a table which has a few fields, one being "datetime_traded". I need to write a query which returns the row which has the closest time (down to second) given a date/time. I'm using MS SQL.
Here's what I have so far:
Code:
select * from TICK_D
where datetime_traded = (select min( abs(datediff(second,datetime_traded , Convert(datetime,'2005-05-30:09:31:09')) ) ) from TICK_D)
But I get an error - "The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.".
Does anyone know how i could do this? Thanks a lot for any help!
I would like to ask some help for estimating necessary hardware for a database, I can tell you about usage profile the following:
- 2 tables, approximately 100.000 records, the tables joined in 1:1 relation, one record is approximately 500 bytes long
- typical scenario:
- select what returns 1 or zero record
- if it returned 1 record an update performed on this record
- the event logged in a third table (one insert)
- this typical scenario needs to run 100-300 times in every second
Can you tell me any advice on sizing of hardware for this? We can rely on a well designed database structure (proper indexes, etc...)

Can display db data in aspx page via f5 , but not localhost unless vs2008 is not running!!!
Have not been able to make vs2008, Sql2005dev, sqlexpress all work together using iis in vista via localhost and vs2008 f5 at same time??
Can€™t do anything with db in solutions explorer, but can work in server explorer if I modify connection back to sqlexpress
Can€™t display data aspx page via localhost
http://localhost/vs2008/
Cannot open user default database. Login failed.
Login failed for user 'NT AUTHORITYNETWORK SERVICE'
Localhost works in iis via virtual directory if I remove db grid in page or vs is not running
Could someone test and tell how to use all of these together?
What is going to happen if I get it to work local and then try to upload to shared host?
<connectionStrings>
<remove name="LocalSqlServer" />
<add name="LocalSqlServer" connectionString="Server=wabpc;Database=VS2008test;Integrated Security=true" providerName="System.Data.SqlClient" />
<add connectionString="Server=SQLEXPRESS;Database=Database.mdf;Integrated Security=true" name="sqlexpress" />
</connectionStrings>
If I close vs2008 and the management studio, localhost works and displays the db info!!
Open vs2008, modify connection back to sqlexpress and the aspx page breaks via localhost
Close vs2008 and local host works
Open vs2008 and get a error 25 in server explorer connection string invalid, but f5 works after the offline clears.
I change db connection back to sqlexpress to work with db in server explorer!
That breaks localhost, but f5 works
Any ideas?

Hello everybody,
I'm developing a report using the following structure :
declare @sql as nvarchar(4000)
declare @where as nvarchar(2000)
set @sql = 'select ....'
If <conditional1>
begin
set @where = 'some where'
end
If <conditional2>
begin
set @where = 'some where'
end
set @sql = @sql + @where
exec(@sql)
I run it in query analyser and works fine, but when I try to run in Reporting Services, Visual studio stops responding and the cpu reaches 100 %.
I realize that when I cut off the if clauses, then it works at Reporting services.
Does anybody know what is happening?
Why the query works in query analyser and doesn't work in Reporting Service ?
Thanks,
MaurĂcio
Hi, I've read that a SQL Server Express database is limited to GB. If I have a database with about 120 tables which store only simple datatypes (int, money, datetimes, varchar, etc.), no blobs or large files, how can I estimate the amount of data or number of rows it can hold before it runs out?

View 7 Replies View RelatedI was having interesting discussion on estimation of log file with a fellow collegue who happens to be quite knowledgable as well.
He told me if we identify the most frequently hit tables for a database and then (sum their sizes * 1.5) for OLAP we get rough estimate for disk space to be allocated for log file.
I have a table like below,
CREATE TABLE Student
(
Id BIGINT not null
,Name NCHAR(20) not Null
,Branch NVARCHAR (64) null
)
The table contains : 100000 rows .
Getting details of below
1)Number of rows in a data page
2)Total number of pages required for the table
3)Total Table size in KB or MB
4)Total file size in Kb or MB

My client's website database is hosted by a third party. I need to alter one of the column definitions for the largest table in the database. Unfortunately, the transaction log fills up if I try to alter the table. I've done all the usual stuff like truncating the log, etc., but the simple fact is that the operation requires more log space than we have available. Therefore, we need to purchase additional disk space for the database.
What I'm looking for is a way to roughly estimate how much log space will be required to alter this table so that we purchase enough but not too much additional space. The table has an identity primary key and 4 other single column indexes: one int, one datetime and two varchar(30) columns.
Any suggestions? Thanks in advance.
How SQL calculates the estimated row count when < or > are used in the WHERE clause of a statement. For example:-
WHERE Created_Datetime_utc > CONVERT(DATETIME,'2014-10-14 10:00:00',102)
I know how the estimated number of rows are calculated when an = is used but I've been googling and cannot find anything about < and >.
I have a table like below,
CREATE TABLE Student
(
Id BIGINT not null

1)Number of rows in a data page
2)Total number of pages required for the table
3)Total Table size in KB or MB
4)Total file size in Kb or MB
