SQL Server 2008 :: Date Manipulation And CASE Statements
Mar 1, 2015
I have a question on date manipulation functions and CASE statements
My sql is passed the following parameter's and performs a select using a manipulation on these date param's to get a start and end date range depending on the conditions;-
monthColHeader = eg 'Feb 2015'
defaultStartDate and defaultEndDate
filterStartDate and filterEndDate.
These are my conditions;-
if defaultStart and End = filterStart and End use monthColHeader for the date range
if defaultStart and End != filetrStart and End AND the month/year of filterStart and filterEnd match then use the filterStart & End month/Year with the monthColHeader to get the date range
if defaultStart and End != filetrStart and End AND the month/year of filterStart and filterEnd DON't match use filterStart Day and monthColHeader for our start date and monthColHeader for our end date.
When I say use monthColHeader I mean like this;-
(r.dbAddDate >= (CAST('@Request.monthColHeader ~' AS DATETIME)) AND r.dbAddDate < DATEADD(mm,1,'@Request.monthColHeader ~'))
This sql works for converting say 'Feb 2015' to '2015-02-01' & '2015-02-28'....
I'm quite new to SQL Server and I have a pretty naive question. I have a table called Company that has a field called Renewal date. I have a task that needs to be run on the first of every month to gather all companies that have Renewal Dates coming up in the next 180 days. The Renewal Date is a datetime field in Sql Server. Is there a way I can have this accomplished.
I have a query with huge number of case statements. Basically I need to short this query with getting rid of these hundreds of CASE statements.
Because of the nature of the application I am not allowed to use a function, and just wondering if there is a possible way to rewrite this with COALESCE().
SELECT CASE WHEN A.[COL_1] LIKE '%cricket%' THEN 'ck' + ',' ELSE '' END + CASE WHEN A.[COL_1] LIKE '%soccer%' THEN 'sc' + ',' ELSE '' END + .... CASE WHEN A.[RESIUTIL_DESC] LIKE '%base%ball' THEN 'BB' + ',' ELSE '' END FROM TableName A
I have a specific requirement. I need to insert the DML statements executed from Management Studio into a SQL table. We have SQL Server 2008 R2 and 2012 instances.
I have two tables TableA and TableB as shown in the example below. I will have to Update TableA based on the data in TableB. If a member in TableB has an EmployerId different from the one in TableA where the EffectiveDate in TableB between the EffectiveDate and ExpirationDate in TableA, then it should void the row in TableA and create rows as shown in the example below (Please refer to the 1st record and the last three records).
I would like to get some suggestions on how to do this efficiently. I am not looking for queries, but I need some ideas...
I have a table with one column as a date field in the form of mm/dd/yyyy and I would like to create a new column on a report as 'Days Open' using the column with random dates in the past and subtracting it from the current system date. Can anyone provide any assistance. I'm very new to SQL Server. I know in Oracle u can use 'sysdate'
I need to to get the result of the function GETDATE and converted to a simpler "mm/dd/yyyy" format in order to compare the results to another date in a table. In ACCESS the function DATE returns the format of 'mm/dd/yyyy' since I need to work with date ranges without a need for this application 'HH:MM:SS'
I have try 'TRANSFORM(GETDATE,'mm/dd/yyyy') but I keep getting errors.
I am not sure what I am doing wrong? Any help is appreciated since I need to work in SQL Server 2000.
Given any date, how can I change that date to be one of the next 3 year cycle dates. These are the fixed cycle dates (always on Sep 1 on those set years) 9/1/1997 9/1/2000 9/1/2003 etc.
For example, if the supplied date was January 4, 1998, it would convert to September 1, 2000 October 31, 2000 -> September 1, 2000 Decemb 12, 2005 -> September 1, 2006 January 1, 1995 -> September 1, 1997
I have data from an OLE DB connection in a Dataflow. This data has a datetime column. I am trying to use a derived column object to add new date data to the destination column in the destination table. I would like to change the data in the datetime column, add some time to the value and add as a new column in the destination. The expression I am trying to use is " DATEADD(Hh, 6 , datevalue). " SSIS doesnt like this expression as the datevalue data is a column. How would I accomplish this task using SSIS?
For this id: 0793319, my beginning date is 2011-09-06
108203492014-09-022015-06-30 208203492013-09-032014-09-01 308203492012-09-042013-09-02 408203492011-12-122012-07-03--not a continuous date range
For this id: 0793319, my beginning date is 2012-09-04
108203492014-09-022015-06-30
For this id: 0820349, my beginning date is 2014-09-02
To find continuous date, you look at the beginning date in row 1 and end date in row 2, then if no break in dates, row 2 beginning date to row 3 end date, if no break continue until last date There could multiple dates up to 12 which I have to check for "no break" in dates, if break, display beginning date of last continuous date.
Greetings All, I was hoping that someone might be able to help me withthe following issue:table ddl:create table exchange(exchangefrom varchar(6),exchangeto varchar(6),exchangecode varchar(6),datemfrom datetime,dateto datetime,exchangerate decimal(28,10))The data in this table under normal conditons will look like:select *from exchangeUSD EURO GL 01/01/2004 01/31/2004 .7523453111USD GBP GL 01/01/2004 01/31/2004 .5384966123USD EURO GL 02/01/2004 02/29/2004 .7523492111USD GBP GL 02/01/2004 02/29/2004 .6004972023My task is to calculate the days delimeted by the start and end date ofthe period which is simple enough:select exchangefrom, exchangeto, exchangecode, datemfrom, dateto,datediff(d, datemfrom, dateto)from exchangeHowever due to circumstances beyond my control the dateto field maycontain a null instead of a valid end date!! YIKES:select *from exchangeUSD EURO GL 01/01/2004 01/31/2004 .7523453111USD GBP GL 01/01/2004 NULL .5384966123USD EURO GL 02/01/2004 02/29/2004 .7523492111USD GBP GL 02/01/2004 02/29/2004 .6004972023My solution to correct the data is to populate the missing end datewith the (start date -1 day) of the next period. However, I am notsure how to do this with SQL? E.g) from the example directly above therow: USD GBP GL 01/01/2004 NULL needs to be updated to:USD GBP GL 01/01/2004 01/31/2004 and this can be done bylooking for the next period (USD GBP GL 02/01/200402/29/2004) that follows and subtracting from its start date 1 day (02/01/2004 - 1 day = 01/31/2004) and that will give me the appropriateend date.If anyone has any insight into solving this problem I would be verythankful.Regards, TFD.
I have data that I want at multiple granularities, 5,15,30 and 60 minutes. To reduce repetition, I have put them all in the same table, so that there is a column for 5,15,30 and 60 minutes, with a filtered index on each of the columns that removes the nulls. This means that each day will have 288 slots, but only 24 of the slots are filled in for 60 min data, and all of them are filled for 5 minute data.
I have another column that specifies the interval granularity, and my first thought was to access my data through a join, where I can use a CASE statement, and depending on the data granularity necessary, it will look at a different column:
INNER JOIN Data d ON AND d.settlement_key = CASE st.interval_granularity WHEN 5 THEN [5_min_settlement_key] WHEN 15 THEN [15_min_settlement_key] WHEN 60 THEN [60_min_settlement_key] ELSE NULL END
Despite the presence of the indexes on the columns, then the process seems to be quite slow, I think probably due to the fact that any query plan isn't going to know beforehand which of the columns it is going to use for any given dataset, until it actually starts to run, so it may not be optimised.
How I could optimise this based on the given structure? Maybe there are hints to be added to the join, or maybe I can clear the query plan each time the SQL is run? My other option for dealing with the data of different granularity was to use one column and repeat the data multiple times, each at the different granularity, but this makes my data, row and table sizes much higher, as we are adding just a column for each additional granularity. Would this work any better in future versions of SQL server, maybe with column store indexes?
The below would work if all of the values in A.Value were numbers but they are not. So I need to restrict the view to only look at the following measures but still show all the other row.
WHERE [Measure] IN ('RTT-01','RTT-04','RTT-07') SELECT M.[Description] ,A.* ,M.Threshold ,M.[Threshold Direction]
[Code] ....
Is there any way that I can create a select statement in the case when to only look for them measures that I know contain numbers?
I'm trying to use SQL for data warehousing using dates for manipulating data. As SQL doesnt have date, just timedate, and if I want to compare 2 dates to obtain someones age ( ie date - date of birth = age ) I have to use a TIMEDIFF or equivelent. This is REALLY annoying. Is there anyway to use just dates without having to code extra?
Does SQL ignore the time part of a datetime column - ie can I just do a date manipulation without concerning myself with the time ( assuming the time is NOT default at 00:00:00 for every entry ) or am I stuck with treating the field as a complete datetime? It may seem a dumbass question, but as I have to do a lot of date manipulations, it is essential to know.
I have 2 piece of code designed to do the same thing. My problem is, i'm not getting the same results.
Code 1 where the results are correct
Code:
select Count(*) as TotalCount, Sum(DistAmt) as TotalSum from table1 inner join table2 on table2.id = table1.id where MailTypeID = 3 AND MailEventID = 2 and table1.IsActive = 1
code 2 - Y is correct, but Z is not, and not only is it not correct, but it is returning a number which equals more then the total rows from the table.
Code:
select Y = sum(case when mailtypeid = 3 and maileventid = 2 and IsActive = 1 then distamt else 0 end), Z = count(case when mailtypeid = 3 and maileventid = 2 and IsActive = 1 then 1 else 0 end) from table1 inner join table2 on table2.id = table1.id
Is there a way to use more criteria in a CASE statement other than CASE WHEN expression THEN value ELSE value END
I need to test if the count is greater than 0. If so, then perform the case statement, else return zeros. Currently there are entries where the values are blank. These blank values are causing errors in the application and unfortunately, I am not able to update these values.
So far I have the following, but I am getting an error stating "An aggregate may not appear in the WHERE clause unless it is in a subquery contained in a HAVING clause or select list, and the column being aggregated is an outer reference."
Thanks in advance!
Code:
IF @Qid = 4 SELECT @Exp as Status, COUNT(*) AS Total, @CourseID as CourseID,
(SELECT question FROM tableQuestions WHERE qid = @Qid) AS Question,
IF COUNT(*)>0 THEN
1.0 * SUM(CASE WHEN A.Q1 > 1 THEN 1 ELSE 0 END) / COUNT(*) AS Positive, 1.0 * SUM(CASE WHEN A.Q1 = 0 THEN 1 ELSE 0 END) / COUNT(*) AS Neutral, 1.0 * SUM(CASE WHEN A.Q1 < 0 THEN 1 ELSE 0 END) / COUNT(*) AS Negative, 1.0 * SUM(CASE WHEN A.Q1 = 0 THEN 1 ELSE 0 END) / COUNT(*) AS NA ELSE 0 AS Positive, 0 AS Neutral, 0 AS Negative, 0 AS NA
END IF
FROM table1 A INNER JOIN table2 B ON A.SessionID = B.SessionID
WHERE (B.CourseID = @CourseID) AND (A.SubmitDate >= @BeginDate) AND (A.SubmitDate <=@EndDate)
Does the ELSE have to state "WHEN [BG_STATUS] <> 'Blocked' and [BG_STATUS] <> 'Closed', etc? Do I have to delineate for the ELSE statement everything that BG_STATUS is *not* equal to? Seems there ought to be a way but I can't find it.
SELECT BG_SEVERITY AS 'Severity', SUM(CASE WHEN [BG_STATUS] = 'Blocked' THEN 1 ELSE 0 END) as 'Blocked', SUM(CASE WHEN [BG_STATUS] = 'Closed' THEN 1 ELSE 0 END) as 'Closed', SUM(CASE WHEN [BG_STATUS] = 'Customer Test' THEN 1 ELSE 0 END) as 'Customer Test', SUM(CASE WHEN [BG_STATUS] = 'Deferred' THEN 1 ELSE 0 END) as 'Deferred',
I am creating a stored procedure which receives the following 4 variables. However, VacancySectorID is the only madatory variable.
@VacancySectorID int = NULL, (mandatory) @VacancyRegionID int = NULL, optional) @VacancyTypeID int = NULL, (optional) @VacancyKeywords nvarchar(64) = NULL, (optional)
My objective is to dynamically build the WHERE statement which in turn will return either one or more of the variables and the required data. The following code works for a single if else but it appears that you cannot have more than one if else statement.
Anyones input would be greatly appreciated.
SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROCEDURE [dbo].[sp_Public_GetVacancyListingBySearchCriteria] ( @VacancySectorID int = NULL, @VacancyRegionID int = NULL, @VacancyTypeID int = NULL, @VacancyKeywords nvarchar(64) = NULL ) AS --SET NOCOUNT ON; IF @VacancySectorID IS NULL AND @VacancyRegionID Is NULL AND @VacancyTypeID IS NULL AND @VacancyKeywords IS NULL BEGIN SELECTviewVacancies.* FROMviewVacancies WHEREVacancyActive = 1 AND VacancySectorID = @VacancySectorID ORDER BYVacancyPosted DESC, VacancyTitle END ELSE BEGIN SELECTviewVacancies.* FROMviewVacancies WHEREVacancyActive = 1 ORDER BYVacancyPosted DESC, VacancyTitle END
whats the most efficient way to do this? I have a column that contains three values. A, B, C If colVal = A add one to batch a, if B add one to batch b...ect . Then display all three values
hi, I want to know how can i equate the following case statements into one Condition? Following is my Code
(case when ws.Action_Taken_ID not in(3,17,18) then '-1' else '0' end) as istechfcr, (case when datediff(day,dbo.Usp_Get_Date(pr.Set_Serial_Number),oh.WO_Record_Date) <= q.Product_Gurantee_Months + 6 then '-1' else '0' end) as istechfcr, (case when substring(ltrim(rtrim(ws.Symptom)),1,1) not in('X') then '-1' else '0' end) as istechfcr, (case when ws.Action_Taken_ID not in(8,15,21,25) then '-1' else '0' end) as istechfcr,

I'm trying to make a view that uses organization name from one tableand contact first and last name from another table. In the view Ihave a field that I want to show Organization followed by the maincontact. Problem is if the organization field or name field is NULLthen it doesn't show anything. If one field is empty I still want itto show the other field in the table.Example:Org1--ContactOrg2--ContactOrg3 (Still shows org even without a contact name)Contact (Still shows contact even without an org name)Tried using a CASE statement but didn't work.
Does anyone know if there is a way to look at a value in a variable and based on that value run different Data Flow Tasks?
For example, let's say I have an SSIS package that contains a variable named Client and 3 separate Data Flow Tasks. I would like to do this: if Client = 1 then run Data Flow 1 else if Client = 2 then run Data Flow 2 else run Data Flow 3.
I'am trying to program a nested CASE statements (if this is not possible, does anyone have any alternate suggestions ?) and I'm getting syntax errors. The statement is:
SELECT @cmdLine = CASE @BackupType WHEN 1 THEN Select @tmpStr = CASE @initFlag WHEN 1 THEN 'BACKUP Database ' + @databaseName + 'TO '+ @backupDeviceName + ' WITH INIT, NOUNLOAD, NAME = ' + @backupJobName + ' , SKIP , STATS = 10, NOFORMAT' ELSE 'BACKUP Database ' + @databaseName + 'TO '+ @backupDeviceName + ' WITH NOINIT, NOUNLOAD, NAME = ' + @backupJobName + ' , SKIP , STATS = 10, NOFORMAT' END WHEN 2 THEN Select @tmpStr = CASE @initFlag WHEN 1 THEN 'BACKUP Database ' + @databaseName + 'TO '+ @backupDeviceName + ' WITH DIFFERENTIAL, INIT , NOUNLOAD, NAME = ' + @backupJobName + ', SKIP, STATS = 10, NOFORMAT' ELSE 'BACKUP Database ' + @databaseName + 'TO '+ @backupDeviceName + ' WITH DIFFERENTIAL, NOINIT , NOUNLOAD, NAME = ' + @backupJobName + ', SKIP , STATS = 10, NOFORMAT' END WHEN 3 THEN Select @tmpStr = CASE @initFlag WHEN 1 THEN 'BACKUP Log ' + @databaseName + 'TO '+ @backupDeviceName + ' WITH INIT, NOUNLOAD, NAME = ' + @backupJobName + ', SKIP , STATS = 10, NOFORMAT' ELSE 'BACKUP LOG ' + @databaseName + 'TO '+ @backupDeviceName + ' WITH NOINIT, NOUNLOAD, NAME = ' + @backupJobName + ', SKIP , STATS = 10, NOFORMAT' END ELSE '' END
I am wondering if there is a way that we could do a nesting case statement in an SQL Query?
This is what I have now... FicaWages = CASE WHEN (UPR00900.FICAMWGS_1 + UPR00900.FICAMWGS_2) >= '84900' AND UPR00400.SBJTSSEC = 1 THEN '0' WHEN UPR00400.SBJTSSEC = 0 THEN '0' ELSE (UPR30100.GRWGPRN - (SELECT SUM(UPR30300.UPRTRXAM) FROM UPR30300 WHERE UPR30300.EMPLOYID = UPR00100.EMPLOYID AND UPR30300.PAYROLCD LIKE '3%' AND AUCTRLCD = 'UPRCC00000007')) END
What I want:
FicaWages = CASE WHEN ('Sql Statement') = 'GRM' THEN CASE WHEN (UPR00900.FICAMWGS_1+UPR00900.FICAMWGS_2) >= '84900' AND UPR00400.SBJTSSEC = 1 THEN '0' WHEN UPR00400.SBJTSSEC = 0 THEN '0' ELSE (UPR30100.GRWGPRN - ('Sql Statement')) END ELSE CASE WHEN (UPR00900.FICAMWGS_1+UPR00900.FICAMWGS_2) >= '84900' AND UPR00400.SBJTSSEC = 1 THEN '0' WHEN UPR00400.SBJTSSEC = 0 THEN '0' ELSE (UPR30100.GRWGPRN - ('Sql Statement')) END END
