The tricky part is I'm joining that same table twice.....would this be better in a max/min case when statement?
I have the following table of data. I need to take a date from a large table and do the following case:CASEWhen date < date(0) Then '0'When date between date(0) and date(1) Then '1'When date between date(1) and date(2) Then '2'When date >= date(3) Then '3'What I need is to be able to read all the dates the the Date table, sort then chronologically, and build the dynamic CASE statement so that the first When statement is < Date(0) and the last When statement is >= Date(Last)I hope I am making sense. Dates will be added to the table about once a year or so and I don't want to keep going back into the sql function and rewrite it with the latest date. Any ideas how to manipulate these dates into a case statement? Don't worry about the second table below. I just wanted you to see why I need to return an int from the Case function.thanksMilton
i was tasked to created an UPDATE statement for 6 tables , i would like to update 4 columns within the 6 tables , they all contains the same column names. the table gets its information from the source table, however the data that is transferd to the 6 tables are sometimes incorrect , i need to write a UPDATE statement that will automatically correct the data. the Update statement should also contact a where clause
the columns are [No] , [Salesperson Code], [Country Code] and [Country Name]
i was thinking of doing
Update [tablename] SET [No] = CASE WHEN [No] ='AF01' THEN 'Country Code' = 'ZA7' AND 'Country Name' = 'South Africa' ELSE 'Null' END
I have successfully built a messaging system into my application, I now in the process of displaying the messages in the UI.
The following are how my tables are constructed.
CREATE TABLE [MailBox].[Message]( [Id] [bigint] IDENTITY(1,1) NOT NULL, [SenderId] [bigint] NOT NULL, [Message] [nvarchar](max) NOT NULL, [SentDate] [datetime] NOT NULL, CONSTRAINT [PK_MailBox.Message] PRIMARY KEY CLUSTERED
[Code] .....
Now I haven't set the foreign key on the MessageReceipient table yet. When someone sends me an email I insert a record into [MailBox].[Message] and output the insert id into MessageReceipient along with the ReceipientId this is working as expected, when I then click on my inbox I call the following stored procedure:
Select p.Username, count(mr.RecipientId) [TotalMessages], CASE WHEN mr.ReadDate is null then 1 -- New message WHEN mr.ReadDate is not null then 0 -- Message has been read END AS NewMessage FROM [User].[User_Profile] p JOIN [MailBox].[Message] m on p.Id = m.SenderId JOIN [MailBox].[MessageRecipient] mr on m.Id = mr.MessageId GROUP BY p.Username, mr.RecipientId, mr.ReadDate
This will give me the person who has emailed me, the total amount of messages and if the message is new or its been read, I do this by checking the ReadDate column as shown in the case statement (but this gives me duplicates, which is not what I want). Lets say user1 emails me 5 times so when I call this proc I will have the same user displayed to me 5 times, what I'm trying to achieve with the proc is it will show User1 as the following:
User1 5 Messages 1 or 0 New Messages
I can get it to display as follow when I remove the case statement
User1 5 Messages
but as soon as I add the case statement back in then I get 5 rows.
How can I change this proc in such a way that it will display the data as follows;
User1 5 Messages 1 or 0 New Messages
New Messages is dependent on ReadDate if its null then we have a new message, otherwise its been read.
I'm trying to create a case statement that if a field = a certain code, I'd like to take another field * 0.9. But, I'm getting a Null value for the answer..here is the statement:,case when parts.ndc = '50242-0138-01' then labels.BAGSDISP*0.9 end "Units Dispensed"..For this example labels.BAGSDISP is a value of 2. So, in theory it should be 2 * 0.9 and the result should be 1.8 but I'm getting a NULL
I have a DistributorInvoiceNumber that can end with in 'R', 'A', 'CRR' or 'CR'.I am trying to write a case statement like so:
CASE WHEN RIGHT([ih].[DistributorInvoiceNumber],1) = 'A' THEN 'ADJ' WHEN RIGHT([ih].[DistributorInvoiceNumber],1) = 'R' THEN 'REV' WHEN RIGHT([ih].[DistributorInvoiceNumber],3) = 'CRR' THEN 'REV' WHEN RIGHT([ih].[DistributorInvoiceNumber],2) = 'CR' THEN 'CREDIT' ELSE NULL END AS 'Status'
For the most part the code is working, with the exception of the fields that just end in 'R'. An example of this is 471268R, 2525125901CRR, 11100325230CR Basically if the number ends with an A, then its an Adjustment, if it ends with JUST an R, then its a Reversal; if it ends with just a CR then it is a Credit and if it ends with CRR then it is a Reversal (Credit Reversal). How can I differentiate between the different R's since three of them end with R? Would I use a RTRIM command somehow?
I'm trying to set up a statement that gives me a field called 'BINNO' if the payor = Commercial. But, I have a few customers that don't have Commercial. They have a Payor of Grant or Part D. How would I set up a statement that looks for Commerical 1st...then Grant or Part D. I started with this
case when inscomp.payor = 'COMMERCIAL' then INSCOMP.BINNO
I am selecting the count of the students in a class by suing select COUNT(studentid) as StCount FROM dbo.student But I need to use a case statement on this like if count is less than 10 I need to return 'Small class' if the count is between 10 to 50 then I need to return 'Medium class' and if the count is more than 50 then 'Big class'.
Right now I am achieving this by the following case statement
SELECT 'ClassSize' = CASE WHEN Stcount<10 THEN 'Small Class' WHEN Stcount>=10 and StCount<=50THEN 'Medium Class' WHEN Stcount>50 THEN 'Big Class' END FROM( select COUNT(studentid) as Stcount FROM dbo.student) Stdtbl
I have a stored procedure in which we are deriving some flags. So, we used series of CASE statements.
For examples
CASE WHEN LEFT(CommissionerCode, 3) IN ('ABC','DEF',...) THEN 1 WHEN PracticeCode IN (.......) THEN 1 WHEN (CommissionerCode IN (.....) OR PracticeCode NOT IN (.....) OR .....) THEN 1 ELSE 0 END
I need to put these conditions in config table and generate dynamic sql.
What is the best way to do this? especially, 3rd condition with OR logic with multiple columns involved.
Below is the scenario which I have currently in my query. I need to write this query without any hardcode values , so that it will work til n number of years without modifications.
Startdate = CASE WHEN Trandate between '06-04-2013' and '05-04-2014' then '06-04-2013' Trandate between '06-04-2012' and '05-04-2013' then '06-04-2012' Trandate between '06-04-2011' and '05-04-2012' then '06-04-2011' Trandate between '06-04-2010' and '05-04-2011' then '06-04-2010' Trandate between '06-04-2009' and '05-04-2010' then '06-04-2009' Trandate between '06-04-2008' and '05-04-2019' then '06-04-2008' END
How I am using a CASE statement within a WHERE clause to filter data:
CREATE PROCEDURE dbo.GetSomeStuff @filter1 varchar(100) = '', @filter2 varchar(100) = '' AS BEGIN SELECT
[Code] .
What I want, is to be able to pass in a single value to filter the table, or if I pass in (at the moment a blank) for no filter to be applied to the table.
Is this a good way to accomplish that, or is there a better way? Also, down the line I'm probably going to want to have multiple filter items for a single filter, what would be the best way to implement that?
I have a bit of trouble getting values into one alias field, my code is below. I am trying to get values into the alias extension, Agent_ID is sometimes null, and so is agent_id2, however sometimes they both have values in them, and then only one of the values is every returned. When in the example below only Agent_ID (11111) is ever returned by I want both of them returned.
Agent_ID Agent_ID2 11111 22222 <code> SELECT DISTINCT CASE WHEN [AGENT_ID] is not null then AGENT_ID when agent_id2 is not null then agent_id2 end as extension FROM [AA_Helper].[dbo].[tblEmpData] </code>
1. I have a simple JOIN statement between A and B, e.g. Cities A JOIN Countries B:
SELECT A.City_Name, B.Country_Code, B.Country_Area FROM Cities A JOIN Countries B ON B.Country_Id = A.Country_Id WHERE B.Country_Type='ABC';
That statement works absolutely fine, very fast (less than a second) and returns me 2 records
2. I need to replace Country Area column with 1 for Europe and 0 for all the rest. I implement so in the following way:
SELECT A.City_Name, B.Country_Code, CASE B.Country_Area WHEN 'EUR' THEN 1 ELSE 0 AS Country_Area FROM Cities A JOIN Countries B ON B.Country_Id = A.Country_Id WHERE B.Country_Type='ABC';
Now to get the same two records it takes 03:55 minutes (!)
I have looked into Estimated Execution Plan, but couldn't spot any difference - all straight forward.
It is SQL 2012 SP1 with compatibility level set to 110
I have a stored proc that contains an update which utilizes a case statement to populate values in a particular column in a table, based on values found in other columns within the same table. The existing update looks like this (object names and values have been changed to protect the innocent):
UPDATE dbo.target_table set target_column = case when source_column_1= 'ABC'then 'XYZ' when source_column_2= '123'then 'PDQ'
[Code] ....
The powers that be would like to replace this case statement with some sort of table-driven structure, so that the mapping rules defined above can be maintained in the database by the business owner, rather than having it embedded in code and thus requiring developer intervention to perform changes/additions to the rules.
The rules defined in the case statement are in a pre-defined sequence which reflects the order of precedence in which the rules are to be applied (in other words, if a matching value in source_column_1 is found, this trumps a conflicting matching value in source_column_2, etc). A case statement handles this nicely, of course, because the case statement will stop when it finds the first "hit" amongst the WHEN clauses, testing each in the order in which they are coded in the proc logic.
What I'm struggling with is how to replicate this using a lookup table of some sort and joins from the target table to the lookup to replace the above case statement. I'm thinking that I would need a lookup table that has column name/value pairings, with a sequence number on each row that designates the row's placement in the precedence hierarchy. I'd then join to the lookup table somehow based on column names and values and return the match with the lowest sequence number, or something to that effect.
how SQL 2012 would treat a literal string for a comparison similar to below. I want to ensure that the server isn't implicitly converting the value as it runs the SQL, so I'd rather change the data type in one of my tables, as unicode isn't required.
Declare @T Table (S varchar(2)) Declare @S nvarchar(255) Insert into @T Values ('AR'), ('AT'), ('AW') Set @S = 'Auto Repairs' Select * from @T T where case @S when 'Auto Repairs' then 'AR' when 'Auto Target' then 'AT' when 'Auto Wash' then 'AW' end = T.STo summarise
in the above would AR, AT and AW in the case statement be treated as a nvarchar, as that's the field the case is wrapped around, or would it be treated as a varchar, as that's what I'm comparing it to.
I have an Address column that I need to Substring. I want to remove part of the string after either, or both of the following characters i.e ',' OR '*'
Example Record 1. Elland **REQUIRES BOOKING IN*** Example Record 2. Theale, Nr Reading, Berkshire Example Record 3. Stockport
How do I achieve this in a CASE Statement?
The following two case statements return the correct results, but I some how need to combine them into a single Statement?
,LEFT(Address ,CASE WHEN CHARINDEX(',',Address) =0 THEN LEN(Address ) ELSE CHARINDEX(',' ,Address ) -1 END) AS 'Town Test'
,LEFT(Address ,CASE WHEN CHARINDEX('*',Address ) =0 THEN LEN(Address) ELSE CHARINDEX('*' ,Address ) -1 END) AS 'Town Test2'
I have a view where I'm using a series of conditions within a CASE statement to determine a numeric shipment status for a given row. In addition, I need to bring back the corresponding status text for that shipment status code.
Previously, I had been duplicating the CASE logic for both columns, like so:
Code Block...beginning of SQL view... shipment_status = CASE [logic for condition 1] THEN 1 WHEN [logic for condition 2] THEN 2 WHEN [logic for condition 3] THEN 3 WHEN [logic for condition 4] THEN 4 ELSE 0 END, shipment_status_text = CASE [logic for condition 1] THEN 'Condition 1 text' WHEN [logic for condition 2] THEN 'Condition 2 text' WHEN [logic for condition 3] THEN 'Condition 3 text' WHEN [logic for condition 4] THEN 'Condition 4 text' ELSE 'Error' END, ...remainder of SQL view...
This works, but the logic for each of the case conditions is rather long. I'd like to move away from this for easier code management, plus I imagine that this isn't the best performance-wise.
This is what I'd like to do:
Code Block ...beginning of SQL view... shipment_status = CASE [logic for condition 1] THEN 1 WHEN [logic for condition 2] THEN 2 WHEN [logic for condition 3] THEN 3 WHEN [logic for condition 4] THEN 4 ELSE 0 END,
shipment_status_text =
CASE shipment_status
WHEN 1 THEN 'Condition 1 text'
WHEN 2 THEN 'Condition 2 text'
WHEN 3 THEN 'Condition 3 text'
WHEN 4 THEN 'Condition 4 text'
ELSE 'Error'
END, ...remainder of SQL view...
This runs as a query, however all of the rows now should "Error" as the value for shipment_status_text.
Is what I'm trying to do even currently possible in T-SQL? If not, do you have any other suggestions for how I can accomplish the same result?
Hello friends, I want to use select statement in a CASE inside procedure. can I do it? of yes then how can i do it ?

Hi All, I've looked through the forum hoping I'm not the only one with this issue but alas, I have found nothing so I'm hoping someone out there will give me some assistance. My problem is the case statement in my Insert Statement. My overall goal is to insert records from one table to another. But I need to be able to assign a specific value to the incoming data and thought the case statement would be the best way of doing it. I must be doing something wrong but I can't seem to see it.
Here is my code: Insert into myTblA (TblA_ID, mycasefield = case when mycasefield = 1 then 99861 when mycasefield = 2 then 99862 when mycasefield = 3 then 99863 when mycasefield = 4 then 99864 when mycasefield = 5 then 99865 when mycasefield = 6 then 99866 when mycasefield = 7 then 99867 when mycasefield = 8 then 99868 when mycasefield = 9 then 99855 when mycasefield = 10 then 99839 end, alt_min, alt_max, longitude, latitude ( Select MTB.LocationID MTB.model_ID MTB.elevation, --alt min null, --alt max MTB.longitude, --longitude MTB.latitude --latitude from MyTblB MTB );
The error I'm getting is: Incorrect syntax near '='.
I have tried various versions of the case statement based on examples I have found but nothing works. I would greatly appreciate any assistance with this one. I've been smacking my head against the wall for awhile trying to find a solution.

Hi This is really bugging me. All I want to do is add a date in an update statement but when I do it, its adding the wrong date e.g. here is my update statement trying to update a date field update tbl_x set [date]=01/02/2006 where id = 1 when i do this the data comes back as 1900-01-01 00:00:00.000, am I doing something wrong, what is the correct way of doing this. Thanks.
Hi i am trying to write a statement to get the players in a squad based on the StartDate, EndDate of any season and the DateEntered, DateLeft a squad the possible situations are Player joins squad after StartDate and is still there (DateLeft Null) Player joins squad after StartDate and leaves before EndDate Player joins before StartDate and is still there (DateLeft Null) Player joins before StartDate and leaves before EndDate
this is my statement at the moment but i am gettin players that are in the squad this season and last season sp if anyone has any ideas i would really appreciate them select spm.SquadId,Person.Id as ID, IsNull(firstName+ ' ','') + IsNull(MiddleName+ ' ','') + IsNull(LastName,'') as Name, spm.DateEntered, spm.DateLeft From Person LEFT JOIN SquadPlayerMapping spm on spm.PlayerId = Person.Id Where spm.SquadId = 2927 And ((spm.DateLeft IS NULL) Or (spm.DateEntered >= (Select StartDate From Seasons Where ID = 50))) And spm.DateEntered <= (Select EndDate From Seasons Where ID = 50) Order by LastName
right now I am able to retrieve the month and year from a field by month(TS_Date), Year(TS_Date), my question is can I put both results as one so output can say Date 2 2008 instead of two columns with month 2 year 2008. any help would be appreciated
I have following SQL statement which I run on an Access database. ( Program written in VB.NET )
'--------- SELECT c.* FROM Communications AS c WHERE CommDate Between #1/4/2005# And #5/4/2005#; '------------
I've put dummy values in the database for dates between 1st and 8th of april... And running this query suprisingly gives back ALL rows in the table... Also the entries for the 6th, 7th and 8th of april... In fact it just gives back the WHOLE table, no matter which values I add...
If I use '1/4/2005' (not with #) then I get an error back.
Anybody an Idea how to make a BETWEEN statement work in an access database?
I have a database with a field which contains a load of dates in this format 01/03/1998
What I want to do is select all the records from the database where the month of the date is what ever, this month or the month the customer selected etc.
I suspected it may be something like the following (which doesnt work)
sql = "SELECT * FROM avail_lowermill WHERE CH_Arrival.month = " & showmonth & " ORDER by CH_Arrival"
I'm using the designer to create/modify strongly typed datasets. I have one select statement that I'm having considerable trouble with. The user selects search parameters from a form. These search parameters are used to filter the data sent to a gridview control. Three of these parameters are almost enough to make me abandon the dataset in this case.The first two are minimum and maximum age. I have a birth date field, but not an age field - ages have a habit of changing without user intervention <grin> and can be calculated. In ASP I'd do something like this:strSQL = "SELECT [DATE OF BIRTH], [FIRST NAME], [LAST NAME], [STATE], [MALE OR FEMALE] FROM members WHERE (DateDiff(yyyy, [DATE OF BIRTH], '" & date & "') >= " & strLowerAge & ") AND (DateDiff(yyyy, [DATE OF BIRTH], '" & date & "') <= " & strUpperAge & ")" I can't figure out how to get datediff working in the designer much less testing against upper and lower age limits.The third parameter is astrological sign. Again, I calculate it based on the birth date. I don't have a field for it. I could, but I would have to modify all the pages that add or edit records to the database to insure all the records that have birth dates also have the right sign. I'm leaning in that direction, but is it possible to accept a sign as a parameter and calculate, based on the birth date, which records qualify? I need to get the age issue fixed. The sign is a nice to have, since I can do it another way if I have to. BTW: I did decide to abandon the dataset in favor of a SqlDataSource control. This allowed me to build my select string in the code behind the way I would have in ASP. This resulted in paging and sorting not working properly. Sorting would be nice, paging is necessary. I'm pretty sure going back to the dataset or using a stored procedure would fix the paging problem, and I've yet to work with stored procedures (it's on my list of things to learn). Any comments or feedback on this would be avidly read and appreciated.Diane
I am trying to use a case statement in one of my stored proc but I am stuck a little bit.Here is a example, something like:declare @id int set @id =1case @id When 1 then select * from contactsend case but this keeps on giving me error: Incorrect syntax near the keyword 'case'. Any help is appreciated!
Hi I have some question regarding the sql case statment.Can i use the case statement with the where clause.Example: SELECT FirstName, IDFROM myTablewhere case when ID= '123' then id = '123' and id='124' endorder by idBut the above code does not work.
Hi all, I was wondering if there is any way in an sql statement to check whether the data your trying to get out of the DB is of a particular type, ie. Int, char etc. I was thinking about a case statement such as <code> CASE WHEN (MyNum <> INT) then 0 end AS MyNum </code>
This has to be included in the sql statement cause I need this field to get other data. Any thoughts on how to achieve this would be greatly appreciated.
If I’m in the wrong thread section please advise of best one to get help in.
