T-SQL (SS2K8) :: Add A Flag When Certain Conditions Are Met?
Aug 27, 2015
I have a table where when an employee works LEAVE1 and LEAVE2 paycodes on the same day then in the new column called 'FLAG' we need to put a 1 for LEAVE1 and a 2 for LEAVE2, when these paycodes are not there on the same day then flag will be NULL as for other paycodes.
Tried using the CASE statements but it always puts a 1 or 2 for the respective paycodes regardless of the fact whether they were together on the same day or not.
WITH SampleData (PERSON,TRANSACTDATE, STARTDATE, END_DATE, IN_PUNCH,OUT_PUNCH,HOURS, PAYCODE) AS
(
SELECT 1234,'08/03/2015','08/03/2015','08/03/2015', '06:00','09:00','3', 'REG1' UNION ALL
SELECT 1234,'08/03/2015','08/03/2015','08/03/2015', '09:00','13:00','4','REG2' UNION ALL
SELECT 1234,'08/04/2015','08/04/2015','08/04/2015', '09:00','13:00','4','LEAVE1' UNION ALL
SELECT 1234,'08/04/2015','08/04/2015','08/04/2015', '14:00','16:00','2', 'LEAVE2'UNION ALL

The situation is that we have resources (trucks) that perform shifts. Shifts consists of actions. A resource can perform multiple shifts.
For every resource we want to find the record that:
- Is 'younger' than the last realized action.
- Has actionkind pickup, deliver or clean
I have constructed a solution with CTE and row_number but I was curious if there would be other alternatives. The fact that I'm joining a CTE onto itself and subject the outcome to a partition makes me think there are sharper ways.
Note that the action id in the data below is also sorted but in practice this need not be the case. The sorting key is prevalent.
This is an exact matching record and straight forward
Is it possible to identify the record using T SQL query based on the following scenarios
1) return the record - If all the three where conditions match 2) if record not found check and return the record where 2 columns values in the where condition match
-- Expected Result for below query: 'Orange', because 2 of the columns in where condition have matching values
SELECT Productname FROM @MappingTable where identification_key1=1 or identification_key2 =2 or identification_key3 =1
Here's my predicament. I changed the filter on an article within a subscription, but not in a meaningful way. I just added "database.dbo." before a column name, but now my subscription is flagged for reinitialization, and won't replicate any transactions unless I start over with a new snapshot. I don't want that to happen. How can I reset the article properties somewhere to get it back the way it was and continue replicating transactions.
(I needed to add "database.dbo" so that another job that looks at the filter info would point to the correct database. Next time maybe I'll just modify the table that stores the filter info)
The reason I don't want to snapshot from the beginning is that I have procedures on the subscribing server that fire triggers from the transactions, so all the jobs "downstream" would get all out of sync.
I am facing a problem in writing the stored procedure for multiple search criteria.
I am trying to write the query in the Procedure as follows
Select * from Car where Price=@Price1 or Price=@price2 or Price=@price=3 and where Manufacture=@Manufacture1 or Manufacture=@Manufacture2 or Manufacture=@Manufacture3 and where Model=@Model1 or Model=@Model2 or Model=@Model3 and where City=@City1 or City=@City2 or City=@City3
I am Not sure of the query but am trying to get the list of cars that are to be filtered based on the user input.
My question is fairly simple. When I join between two tables, I always use the ON syntax. For example:
SELECT
* FROM
Users
JOIN UserRoles
ON (Users.UserRoleId = UserRoles.UserRoleId)
No problems there. However, if I then decide to further filter the selection based on some trait of the UserRole, I have two options: I can add the condition as a WHERE statement, or I can add the condition within the ON block.
--Version 1:
SELECT
* FROM
Users
JOIN UserRoles
ON (Users.UserRoleId = UserRoles.UserRoleId) WHERE
UserRoles.Active = 'TRUE'
-- Version 2
SELECT
* FROM
Users
JOIN UserRoles
ON (Users.UserRoleId = UserRoles.UserRoleId
AND UserRoles.Active = 'TRUE')
So, the question is, which is faster/better, if either? The Query Analyzer shows the two queries have the exact same execution plan, which makes sense, since they're both joining the same tables. However, I'm wondering if adding the condition in the ON statement results in fewer rows the JOIN statement initially needs to join up, thus reducing the overall initial size of the results table before the WHERE conditions are applied.
So is there a difference, performance wise? I imagine that if Users had a thousand records, and UserRoles had 10 records, then the JOIN would create a cartesian product of the two tables, resulting in 10,000 records in the table before the WHERE conditions are applied. However, if only three of the UserRoles is set to Active, would that mean that the resulting table, before applying WHERE conditions, would only contain 3000 records?
Hi, I'm trying to use trace flag 1204 to get some detailed deadlock information In EM, I add startup parameter -T1204, and then I stop and start the server. I run two jobs that I have setup to deadlock, and they do. But no information about the deadlock is in my sql error log? anyone know what I am doing wrong? thanks.
I have a perl script (uses sql query) that will run if there is anyupdate in the row. Currently, I am a trigger that sets the DateModifiedfield with getdate() Then my perl script looks for certain range ofmodified dates and runs the necessary query.I am trying to come up with a different mechanism where I don't have touse the date field. I am looking into flag bits. But not sure howto use it.Should I create a trigger that will set the flag bit after any update?This way the script will just look for the updated records, regardlessof what time it was updated. Maybe I am misunderstanding flag bits, thenafter another subsequent update how would the perl/sql script know whichrecords were updated? I hope this make sense.thanks.--s
I'm working on a program and I want it to check to see if the database it is pointed to has had a backup done against the database in the last 10 days. I will then throw a message box indicating that the database has not been backed up and that they should consider doing so.
Is there any attibute that I can check to see when the last time the database was backed up?
I am trying to build a decision tree algorithm with multiple regressors. I am having trouble changing the properties for the input variables to regressors (the only multiple flag choice is "not null"). I created a mining model using the DMX query thinking I could change the code to include multiple regressors, however I get a syntax error when trying to execute the model. Also, I am wondering if you can view the dmx code for a model built using the mining wizard.
If you have a table with columns like Category int, Cost money, EffectiveDate DateTime, SpecialFlag (char Y or N) how would you write a query to get for each category, get the most recent, with a specialFlag of Y if a Y record exists and if not, grab the N record?
I have tried using the exists clause for the flag, but as soon as I mix in the group by to get the latest effectivedate, the max is evaluated first and I am not guaranteed to use the Y records if they exist.
To illustrate: A 1, $10, 1/1/2007 Y B 1, $12, 1/1/2007 N C 2, $5, 6/7/2007 N D 2, $4, 1/1/2007 N E 3, $1, 1/1/2007 Y F 3, $2, 6/7/2007 Y G 3, $3, 2/1/2008 N
I want records A because it is flagged Y, C because it is the most recent and there is no Y record and F because it is flagged and most recent.
I am using this select statement to radomly display a recordSelectCommand="SELECT TOP 1 * FROM [TBL_Example] ORDER BY NEWID()I need to, however, flag this record, to determine if it has already been previously randomly selected, and won't take part in future random selections.I will need to add a where clause to the above, but what I am unsure of is what I should do for the insert statement. I guess I could figure this out on my own as well if I could determine a means to prgramatically store my PK from the above record in session.Any ideas?
i want to make a stored procedure that will update the notification flag in the table.
If the email was succesfully sent the flag will be updated as SENT. And if it is un successful the flag will be NOT SENT in column of the table in SQL. The email will be send using .NET codes and updates of notification flag will use SQL stored procedure. Please help
I have a table with 4 columns,let say ID, WorkId , HireDate ,TerminateDate
My source date
ID  WorkId  HireDate   TerminateDate 1    123   2006-01-05  2013-01-13 1    456   2006-02-23  2013-04-13 1    789   2005-12-12  2013-06-13 2    913   2004-12-15  2012-01-13 2    406   2006-04-13  2014-04-13 3    113   2009-11-15  2011-01-13 3    106   2010-04-13  4    513   2002-11-15  4    168   2011-10-23  5    342   2007-01-05  2009-01-13      5    416   2008-02-23                   5    159   2008-12-12  2010-06-13   6    542   2005-01-03  2007-01-13     Â
Rule -1:Â set flag = yes
-Whenever terminatedate is not null -Also with in the ID group if one record terminatedate is null then set flag=yes
Rule-2: Set flag=No - with in the ID group Whenever terminatedate is null
My output should look like this..

In order to use Microsoft Dynamics NAV with the SQL Server 2005, I need to set Trace Flag 4616, and I know it's a setting somwhere, where I can add this flag no. -but I can't remember where? Please help?
I created a package wide OnError event handler with the following script:
Imports System
Imports System.Data
Imports System.Math
Imports Microsoft.SqlServer.Dts.Runtime
Public Class ScriptMain
' The execution engine calls this method when the task executes.
' To access the object model, use the Dts object. Connections, variables, events,
' and logging features are available as static members of the Dts class.
' Before returning from this method, set the value of Dts.TaskResult to indicate success or failure.
'
' To open Code and Text Editor Help, press F1.
' To open Object Browser, press Ctrl+Alt+J.
Public Sub Main()
'
Dts.Variables("FailureFlag").Value = True
'
Dts.TaskResult = Dts.Results.Success
End Sub
End Class
I ran the package with an error and set a break on error condition. When I looked at the value of "FailureFlag" it was False. Any ideas why it is not being set?
I have a post execute event that is supposed to rollback from a snapshot on failure and it is not doing so on failure so I'm trying to figure out what's wrong.
Knifflige Frage zu Datenbanken:Es gibt Tabellen, die mehr als ein PK-Feld haben; also z.B.MAID und GMID.Soweit ok.Nehmen wir an, aus dieser Tabelle sollen keine Datensätze physikalischgelöscht werden, sondern der Löschstatus durch ein Datenfeld GELOESCHTangegeben werden. Hat das Feld den Wert 0, dann ist der Datensatz nichtgelöscht; ansonsten steht der Zeitpunkt (Tag und Uhrzeit) der Löschung drin.Dann funktioniert der PK nicht mehr, denn es können ja durchaus mehrereDatensätze mit gleicher MAID und GMID vorhanden sein. Aufnehmen vonGELOESCHT in den PK geht theoretisch, ist aber gefährlich (daFließkommafeld, und wer weiß schon, ob 0 immer gleich 0 ist...).Hat jemand eine Idee?SWE@KP
I recieved an alert that says 'The Auto Shrink flag for database is not set according to best practice.' Can anyone tell me where I can find this flag and what it shoul dbe set to?
i am using Sql Server 2005 SP2, I am trying to configure Mirroring. The issue is ,After configuring mirroring ,Whem i am starting START MIRRORING button .I am getting the error
Database mirroring is disabled by default. Database mirroring is currently provided for evaluation purposes only and is not to be used in production environments. To enable database mirroring for evaluation purposes, use trace flag 1400 during startup. For more information about trace flags and startup options, see SQL Server Books Online. (Microsoft SQL Server, Error: 1498)
I used BDCC TRACEON (1400) and I altered the Startup parameter in configuration manager of SQL SERVER ;-T1400
But still I am getting the above error which is indicated in red
I know that several hotfixes need you to turn on trace flag 4199 to activate them. But after reading an article on that trace flag, and the way it was worded, I couldn't tell if you still needed to use the trace flag, once that hotfix was incorporated into a service pack.
I was using Type 2 for one of our Fact table.... and need to put a flag to know which one is the Current record... I couldn't able to figure how to implement logic in the merge statement... This is an example Query ....I was using like this for my fact table...
Basically I need to track CustomerName and City... So I need a Currentflag (Y)Â for latest record....
MERGE INTO [dbo].[TargetCustomer] AS TRG USING [dbo].[MyCustomers] AS SRC ON TRG.[CustomerID] = SRC.[CustomerID] AND TRG.[CustomerName]=SRC.[CustomerName] AND TRG.[City]=SRC.[City]
Right now I have a cursor that makes me want to puke. This is the last cursor in my current project and I want to replace it with a much faster set based operation.
Here is the problem. I have a table with say 1-3 million records. There are fields that get loaded in with date information. These fields are varchar because the date information could very well be mangled data that needs to be reviewed by a user. What I need is to go through these varchar fields and flag the values that cannot convert to smalldatetime.
I have another table that houses the primary key and the field of the record that cannot convert.
Essentially, I have a series of filters that run and flag using set based stored procedures. If there is a record that gets through that contains a value that cannot be converted, I have a cursor that steps through the data and attempts to convert the value. If it is able to be converted, then it continues on until it finds the value that is holding up the conversion.
I guess if I can run a query that will return all records that can convert for the field (or can't convert) I'd be all set. Any help here is appreciated.
I need to display the 'Flag' column in the result set as mentioned above to identify the cycle values without breakdown indicator values. Here is the logic for this,
1. Need to set the flag 'Yes' for the cycle values PM04 to PM04 in the OrderType and if there is any breakdownindicator value 'X' then we can not consider that cycle for Flag.
I get this error when, i try to set a parameter for user input, it doesnt matter what i type in, it says this:
<<Query (1,408) The Restrictions imposed by the constrained flag in the STRTOSET function were violated>>
what exactly does this mean? and how do i fix it?
My parameter is for dates, but i have the datetype set to "String", when i change it to" DATETIME" , i get the same error when i select from the calendar. So far the only date option that is working right now. Is a long drop down list, that could go for days at a time. I just want users to be able to input dates, such as "Jan 9, 2000" or 10/10/1999. What can i do about this?
I am having a really hard time trying to get around the auto generated MDX when I use a date as a parameter. It is forcing the values to be string and this is not allowing me to use the date picker on the reports. Can anyone help me figure this one out? Is there any way to use the date picker when using a cube dataset?
I am using OLE DB provider for Foxpro (VFPOLEDB.1) to query DBF files. I need to migrate the content of these files to a SQL Server 2005 database.
These DBF files have some (actually a lot) records marked as deleted using the DBF 'deleted' flag. When I submit a SELECT command to the OLE DB Provider, it returns me all the non-deleted records from the file.
It is very Ok as long as the 'deleted' rows actually have no more business value, but in my case, I need to do some processing on them, and even to migrate their data.
What are the options available for me to be able to query and differentiate the 'deleted' records ?
