I'm trying to use the DateDiff function within my select statement, but I'd like to add the parameter of greater than 30 days. This will have the query only return records where my bill stop date is greater than 30 days from the completion date. I currently have the datediff function within my select statement as
DATEDIFF (d,A.StopBillDate, a.CompletionDate) as [DIFFERENCE]
I would prefer to keep the datediff function within the select statement so as to have difference in days appear as a column within my output.I have been unable to add the parameter of > 30 days to the query without getting an error.
CREATE FUNCTION GetPerson (@SSN integer, @NamePrefix varchar(10), @FirstName varchar(30), @MiddleName varchar(30), @LastName varchar(40), @NameSuffix varchar(10), @HomeID integer, @MailID integer, @DOB timestamp, @Gender varchar(1), @MaritalStatus varchar(1)) RETURNS integer as BEGIN DECLARE @PersonID integer set @PersonID=0 if @SSN>0 and @SSN<999999999 Begin select Min(lngPersonID) AS PersonID from Persons where lngSSN=@SSN End ELSE if @SSN is not null BEGIN IF @LastName is not null and @FirstName is not null and @MiddleName is not null and @NamePrefix is not null and @NameSuffix is not null Begin select MIN(lngPersonID) AS PersonID from Persons where strNamePrefix= @NamePrefix and strFirstName=@FirstName and strMiddleName=@MiddleName and strLastName=@LastName and strNameSuffix=@NameSuffix and lngSSN=@SSN End ELSE if @LastName is not null BEGIN select MIN(lngPersonID) as PersonID from Persons where strLastName=@LastName and lngSSN = @SSN END END return (@personID) END
I m having problem with the "Select" function the error I m getting is Select statements included within a function cannot return data to a client (error 444)
Cann I use "select" statement in the function? If not what is the alternative?
I reduced the size of the sproc because it is a big one, I donn have any proble with syntax.
I've got a complex UDF I need to call twice in a select statement, as shown below:
SELECT
dbo.myFunction(colName), dbo.myFunction(colName) * 2 FROM
tableName
The problem is, the result of "dbo.myFunction(colName)" is not being cached, so the function is executed again for "dbo.myFunction(colName) * 2". This is having a significant impact on performance (doubling the amount of time it takes for the query to execute).
Is there any way I can write the query so that dbo.myFunction is only executed once?
Ok, for a bunch of cleanup that i am doing with one of my Portal Modules, i need to do some pretty wikid conversions from multi-view/stored procedure calls and put them in less spid calls.
currently, we have a web graph that is hitting the sql server some 60+ times with data queries, and lets just say, thats not good. so far i have every bit of data that i need in a pretty complex sql call, now there is only one thing left to do.
Problem: i need to call an aggregate count on the results of another aggregate function (sum) with a group by.
*ex: select count(select sum(Sales) from ActSales Group by SalesDate) from ActSales
This is seriously hurting me, because from everything i have tried, i keep getting an error at the second select in that statement. is there anotherway without using views or stored procedures to do this? i want to imbed this into my mega sql statement so i am only hitting the server up with one spid.

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
SELECT DATEDIFF(n , LAG(CAST(Date AS DATETIME) + CAST(Time AS DATETIME), 1) OVER ( ORDER BY Date, Time ), CAST(Date AS DATETIME) + CAST(Time AS DATETIME)) FROM [DataGapTest]
Gives the right output:
NULL 1 1 3548 0
However, when I put the statement in a function, I get only zeros as the output. It's as if the lag and current value are always the same (but they are not of course).
CREATE FUNCTION dbo.GetTimeInterval(@DATE date, @TIME time) RETURNS INT AS BEGIN DECLARE @timeInterval INT SELECT @timeInterval = DATEDIFF(n , LAG(CAST(@Date AS DATETIME) + CAST(@Time AS DATETIME), 1) OVER ( ORDER BY Date, Time ), CAST(@Date AS DATETIME) + CAST(@Time AS DATETIME)) FROM dbo.[DataGapTest] RETURN @timeInterval END
I tend to learn from example and am used to powershell. If for instance in powershell I wanted to get-something and store it in a variable I could, then use it again in the same code. In this example of a table order items where there are order_num, quantity and item_prices how could I declare ordertotal as a variable then instead of repeating it again at "having sum", instead use the variable in its place?
Any example of such a use of a variable that still lets me select the order_num, ordertotal and group them etc? I hope to simply replace in the "having section" the agg function with "ordertotal" which bombs out.
select order_num, sum(quantity*item_price) as ordertotal from orderitems group by order_num having sum(quantity*item_price) >=50 order by ordertotal;
Hi, I am facing problem rite now.. I want to calculate the date different minutes between 23:00:00 and 01:00:00. My code : datediff(Minute,'01:00:00','23:00:00') The result is 1320 minutes. (22 hours)... But, the result that I want is 120 minutes (2 hours).... Can anybody help ??? Thanks in advance...
Hi,I'm using the datediff function to display the ages of the users in my database. However the age rounds up once they are 35.5 etc...I could create another function which works similar to the DateDiff function, but use math.floor to always round down, but I need to use this function in a SQL statement WHERE clause. Is there any way around this?Thanks,Curt.
I am trying to break up the age into column from a dob field for a cross tab report. I can query the datediff with an alias but can not individually change the columns I need like a virtual or temp column, but can't figure out how to accomplish it.
use 'Database'
Select datediff(Year, dob, getdate()) As "Under 22", datediff(Year, dob, getdate()) As "22-45",
datediff(Year, dob, getdate()) As "46-65", datediff(Year, dob, getdate()) As "Over 65"
from 'Table'
WHERE (DATEDIFF(yy, dob, GETDATE()) < 22 OR
DATEDIFF(yy, dob, GETDATE()) BETWEEN 22 AND 45 OR
DATEDIFF(yy, dob, GETDATE()) BETWEEN 46 AND 65 OR
DATEDIFF(yy, dob, GETDATE()) > 66) AND (status = 'Current' OR

I have two date columns one is sent_date and other is approved_date my requirment is to find the difference between the two dates which can be minutes/hrs/days. using datediff function iam able to get it in minusts or hrs but my output should be of the format hh:mm 23:10 (ie 23 hrs and 10 min) or say 48:00 (for 2 days)
recently i created a system using php and mysql to record faults that the ict technicians could get reported faults out of. so far it does everything i want but some senior members of staff now want the front end to give a report of status, one of the things they wish to see is how many jobs have been completed this week month and year
within my tables is a field date. naturally it has the date submited contained within it. the code i have been using to try and get an output is
mysql_query("SELECT date, datediff('day', date, CURRENTDATE) FROM softwarerepairtable WHERE datediff<= '7' and complete='yes' ");
the complete feild is another contained within the datebase. i have also tried SELECT * datediff('day', date, CURRENTDATE) FROM softwarerepairtable WHERE datediff<= '7' and complete='yes' ");
unfortunatly my limited knowledge of php and sql is holding me back on this. any help guys would be appriacted
Hi Experts,I am working on SSRS 2005, and I am facing a problem in counting theno of days.My database has many fields but here I am using only two fieldsThey are Placement_Date and Discharge_DateIf child is not descharged then Discharge_Date field is empty.I am writing below query to count the number of days but is is notworking it is showing the error"The conversion of a char data type to a datetime data type resultedin an out-of-range datetime value."select casewhen convert(datetime,Discharge_Date,103) = '' thendatediff(day,CONVERT(datetime,Placement_Date,103), GETDATE())elsedatediff(day,CONVERT(datetime,Placement_Date,103),CONVERT(datetime,Discharge_Date,103))end NoOfDaysfrom Placement_DetailsSo please tell me where I am wrong?Any help will be appriciated.RegardsDinesh
Select COUNT(DATEDIFF(d, DateintoSD, SDCompleted) - DATEDIFF(ww, DateintoSD, SDCompleted) * 2) AS 'Total Jobs Completed' From Project WHERE (SDCompleted > @SDCompleted) AND (SDCompleted < @SDCompleted2) AND (BusinessSector = 34) AND (req_type = 'DBB request ')
When running a query such as this on a database view:
select count(*) from WWALMDB.dbo.v_AlarmEventHistory2
SQL throws the following error:
The datediff function resulted in an overflow. The number of dateparts separating two date/time instances is too large. Try to use datediff with a less precise datepart.
Oddly on a Table the count(*) function works.
Is there a limit on views or the count(*) function that I am not aware of?
Dear all, I have the Following Query:SELECT DATEDIFF(day, GETDATE(), RECENT_RESERVATION)AS Expr1,RECENT_RESERVATION FROM EMP WHERE SUN=empName;when i run it inside the query analyzer, it returns two columns. but if run it inside The ASPX page it retuns only one column wich is RECENT_RESERVATION date.Note: i am using one methode that takes care of reading from SQL and assigning the result into an array, it works fine everywhere, but with this query it dosen't work. Any suggestions??
I have added one webpage designed in ASP.Net with C# and sql server 2005 as database. There is table for user registration in which there is a column for ProfileCreationDate the data type of that column is date time .
I would like to fetch data of those user who have created profile within 7 days. For getting desired result I am trying this query.
select Name ,Profession,ProfileCreationDate from tblRegistration where DATEDIFF ( Day , '" + System.DateTime.Now + "',ProfileCreationDate)<7 order by ProfileCreationDate DESC
System.DateTime.Now is a function for getting current date time in C#
The query is neither giving error nor giving desired result.
Aim – Calculate the number of days between the [CreatedDate] and getdate, however if stage name = ‘Live Transactions’ then Calculate the number of days between [CreatedDate] & [CloseDate]
This is my query so far
SELECT [CreatedDate] ,[StageName] ,[CloseDate] ,DATEDIFF(dd,CONVERT(datetime,[CreatedDate]),GETDATE()) as Age FROM [FDMS].[Dan].[Raz_Reporting_LCS]
Select COUNT(DATEDIFF(d, DateintoSD, SDCompleted) - DATEDIFF(ww, DateintoSD, SDCompleted) * 2) AS 'Total Jobs Completed' From Project WHERE (SDCompleted > @SDCompleted) AND (SDCompleted < @SDCompleted2) AND (BusinessSector = 34) AND (req_type = 'DBB request ')
i've tried using the SELECT SQL sentence on PPC with UNION and INNER JOIN in combination with DATEDIFF function which works fine on ordinary SQL but obviously does not work on compact edition. Is there some workaround?
SQL sentence that works:
Code Snippet
SELECT * FROM ( SELECT 'O' Type, O.Name , OC.Name Contact, Birthday FROM OutletContact OC INNER JOIN Outlet O ON OC.OutletID=O.OutletID UNION SELECT 'W' Type, W.Name,WC.Name Contact, Birthday FROM WholesalerContact WC INNER JOIN Wholesaler W ON W.WholesalerID=WC.WholesalerID ) S WHERE Birthday IS NOT NULL AND (DATEDIFF(day,GETDATE(),Birthday) BETWEEN 0 AND 14)
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
Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".
Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.
hiI need to write a stored procedure that takes input parameters,andaccording to these parameters the retrieved fields in a selectstatement are chosen.what i need to know is how to make the fields of the select statementconditional,taking in consideration that it is more than one fieldaddedfor exampleSQLStmt="select"if param1 thenSQLStmt=SQLStmt+ field1end ifif param2 thenSQLStmt=SQLStmt+ field2end if
Code Block SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02' FROM myTables WHERE Conditions are true ORDER BY Field01
The results are just as I need:
Field01 Field02
------------- ----------------------
192473 8461760
192474 22810
Because other reasons. I need to modify that query to:
Code Block SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02' INTO AuxiliaryTable FROM myTables WHERE Conditions are true ORDER BY Field01 SELECT DISTINCT [Field02] FROM AuxTable The the results are:
Field02
----------------------
22810 8461760
And what I need is (without showing any other field):
Field02
----------------------
8461760 22810
Is there any good suggestion? Thanks in advance for any help, Aldo.
