I have a problem with a SQL that check if a date column IS NULL.
On one server the check work ok but on another (the same data is on both - restored copy) the check does not find any NULL values.
If check where datecolumn =convert(datetime,'9999-12-31 23:59:59.000',121) I get the same result as when checking for NULL in the other.
Is there any parameter set somewhere that tell the server to return a value even if NULL is stored in the database?
I've built a sample CLR function with the following declaration....
CREATE FUNCTION GetManager(@DeptCode nvarchar(3)) RETURNS nvarchar(1000) WITH RETURNS NULL ON NULL INPUT AS EXTERNAL NAME Assembly1.[ClassLibrary1.MyVBClass].MyManager
It returns the value "Unknown" as it would have for any unknown DeptCode, as-programmed.
I'm of the theory it should have returned NULL without actually firing the function? Or is this only for non-CLR items... or stored procedures, not functions?
i have written a sql function which returns only number of working days (excludes holidays and Weekends) between given StartDate and EndDate.
USE [XXX] GO /****** Object: UserDefinedFunction [dbo].[CalculateNumberOFWorkDays] Script Date: 10/28/2015 10:20:25 AM ******/ SET ANSI_NULLS ON GO
[code]...
I need a function or stored procedure which will return the date which is 15 working days (should exclude holidays and Weekends) prior to the given future Date? the future date should be passed as a parameter to this function or stored procedure to return the date. Example scenario: If i give date as 12/01/2015, my function or stored procedure should return the date which is 15 working days (should exclude holidays and Weekends) prior to the given date i.e 12/01/2015...In my application i have a table tblMasHolidayList where all the 2015 year holidays dates and info are stored.
I currently have a stored procedure that looks something like this SELECT * FROM tblQuestions WHERE Title LIKE ISNULL('%'+@Name+'%', Title)I have a form that supplies this value. This statement should make it so that if a NULL value is passed in, then it will return all the rows, if some text is specified, then it will not. On my SQLDataSource on the page where the parameter is supplied I have set ConvertEmptyStringsToNull to True, but when I say in my code,SqlDataSource1.SelectParameters.Add("@Name", TextBox1.Text);It won't give me back any of the rows, I know that the stored procedure works fine because I can get it to work by a basic query and other testing on it, so somewhere in my form, the NULL value isn't being passed, I belive that it is passing an empty string and I don't know why. Thank you in advance /jcarver
Hello, everyone! I have some fields that must have data entered into them(i.e they shd not be left blank) & since the data has to be different almost everywhere I cannot set a default also. However I have defined these columns as NOT NULL, but still when data is entered they accept null values. WHY? Please help! Thanks in advance! Adie
I'm building a stored procedure to edit a row in my database but first I'm wanting to check for null values in the parameters and set them to their respective value in the row I'm attempting to edit.
I'm building a stored procedure to edit a row in my database but first I'm wanting to check for null values in the parameters and set them to their respective value in the row I'm attempting to edit.
The problem I'm having is described below all this code.---------------------------------------------------------My content page has a SqlDataSource: <asp:SqlDataSource ID="sqlGetUserInfo" runat="server" ConnectionString="<%$ ConnectionStrings:RemoteNotes_DataConnectionString %>" SelectCommand="SELECT [UserFirstName], [UserLastName] FROM [Users] WHERE ([UserGUID] = @UserGUID)" onselecting="sqlGetUserInfo_Selecting"> <SelectParameters> <asp:Parameter Name="UserGUID" Type="String" /> </SelectParameters> </asp:SqlDataSource> -----------------------------------------------------Inside my OnSelecting event, I have: protected void sqlGetUserInfo_Selecting(object sender, SqlDataSourceSelectingEventArgs e) { sqlGetUserInfo.SelectParameters["UserGUID"].DefaultValue = Membership.GetUser().ProviderUserKey.ToString(); } ---------------------------------------------------------------------And, inside my Page_Load, the relevant code is: //String strUserFirstName = ((DataView)sqlGetUserInfo.Select(DataSourceSelectArguments.Empty)).Table.Rows[0]["UserFirstName"].ToString(); DataView dvUserDetails = (DataView)sqlGetUserInfo.Select(DataSourceSelectArguments.Empty); if ((dvUserDetails != null) && (dvUserDetails.Count > 0)) { DataRow drUserInfo = dvUserDetails.Table.Rows[0]; lblHelloMessage.Text = "Hello, " + drUserInfo["UserFirstName"].ToString() + ((drUserInfo["UserLastName"].ToString() == "") ? "" : " " + drUserInfo["UserLastName"].ToString()); } ---------------------Now, here's the problem. My "if" statement is never executing because "dvUserDetails" is null. However, when I break the execution and put awatch on the actual Select() statement, it shows a DataView with the correct return rows! You can see the commented line where I tried tobypass the DataView thing (just as a test), but I get an object reference is null error.The weird thing is that it was working fine one minute, then started getting "funky" (working, then not, then working, then not), and now it just doesn't work at all. All thiswithout me changing one bit of my code because I was checking out some UI flow and stopping and restarting the application. I've tracked downthe temporary files directory the localhost web server runs from, deleted all those files, and cleaned my solution. I've even triedrebooting, and nothing seems to make it work again.My relevant specs are VS2008 9.0.21022.8 RTM on Vista Enterprise x64.
Hi;I'm here for many hours trying to do this but i couldn't find a way.I have a table whith a field called [DOB], where i have people's date of birth. Now, i need a SQL query to get people who's birthdays are in between two dates "BUT", what about the year on the date? I use to do this on Access: SELECT * FROM Members WHERE DATESERIAL(YEAR(NOW()), MONTH(DOB), DAY(DOB)) BETWEEN @startDate AND @endDate In the query above the year is not a problem because the DateSerial() function add the current year for all birthdates making it easyer to user parameters like: 06/01/2006 to 06/30/2006 Unfortunately, SQL Server does not support DateSerial() function. I appreciate any help on this. Thanks a lot.
Hello Everyone and thanks fo ryour help in advance. I am working on a blog site that stores each blog entry in a SQL Server table. Each entry is date stamped with the time it is created in a datetime field called "TimeCreated". I want to be able to create some type of ability to sort the older blogs as an archive and display links on a pages such as "Archive - January 2007, Archive - December 2006" etc. I'm not exactly sure on how to go about doing this. any help on this topic would be greatly appreciated.
Hey Guys, I can’t get this date conversion stuff to work. I have a variable that holds the current date -1 day (@Yesterday). The date that is on the table (DTE) is in the format yyyymmdd (i.e. 20021213), but I cannot get the date to convert.
I have tried: BEGIN DECLARE @Yesterday as nvarchar (8);
I need to calculate a date.example it needs to be 20 working days ago compared to today so that means it needs to not include any Saturday or Sunday in between
declare @start_date datetime declare @end_date datetime declare @working_days int set @working_days = 20
[code]...
So I need to calculate @start_date but it needs to exclude any weekend days.@working_days is the number of working day I'm interested in.
Hello,I am importing data that lists rates for particular coverages for aparticular period of time. Unfortunately, the data source isn't veryclean. I've come up with some rules that I think will work to clean thedata, but I'm having trouble putting those rules into efficient SQL.The table that I'm dealing with has just under 9M rows and I may needto use similar logic on an even larger table, so I'd like somethingthat can be made efficient to some degree using indexes if necessary.Here is some sample (simplified) code:CREATE TABLE Coverage_Rates (rate_id INT IDENTITY NOT NULL,coverage_id INT NOT NULL,start_date SMALLDATETIME NOT NULL,end_date SMALLDATETIME NOT NULL,rate MONEY NOT NULL )GOINSERT INTO Coverage_Rates VALUES (1, '2004-01-01', '2004-06-01',40.00)INSERT INTO Coverage_Rates VALUES (1, '2004-03-01', '2004-08-01',20.00)INSERT INTO Coverage_Rates VALUES (1, '2004-06-01', '2004-08-01',30.00)INSERT INTO Coverage_Rates VALUES (2, '2004-01-01', '9999-12-31',90.00)INSERT INTO Coverage_Rates VALUES (2, '2004-03-01', '2004-08-01',20.00)INSERT INTO Coverage_Rates VALUES (2, '2004-08-01', '2004-08-01',30.00)GOThe rule is basically this... for any given period of time, for aparticular coverage, always use the coverage with the highest rate. So,given the rows above, I would want the results to be:coverage_id start_dt end_dt rate----------- ---------- ---------- --------1 2004-01-01 2004-06-01 40.001 2004-06-01 2004-08-01 30.002 2004-01-01 9999-12-31 90.00There can be any combination of start and end dates in the source, butin my final results I would like to be able to have only one distinctrow for any given time and coverage ID. So, given any date @my_date,SELECT coverage_id, COUNT(*)FROM <results>WHERE @my_date >= start_dtAND @my_date < end_dtGROUP BY coverage_idHAVING COUNT(*) > 1the above query should return 0 rows.Thanks for any help!-Tom.
My SQL Server 2005 database table data definition is as follows:
ID int LST_DATE DateTime SUBJECT varchar(100)
An example of a record in the database table has a date format like this: 23/10/2007 16:56:00. My VB code as below:
Dim Command As New SqlClient.SqlCommand("SELECT ID,LST_DATE,SUBJECT FROM dbo.LISTS WHERE LST_TIME = GETDATE(), 100)))", conn)
Dim dataReader As SqlClient.SqlDataReader = Command.ExecuteReader(CommandBehavior.CloseConnection) While dataReader.Read() Dim NWAlert As New Alert(dataReader("SUBJECT").ToString(),DateTime.Parse(dataReader("LST_DATE").ToString()))) :
LST_TIME should be equals the CURRENT DATE & TIME in the format above to activate.
I have tried using the following: WHERE LST_DATE = CONVERT(GETDATE(), 103) + ' ' + CONVERT(GETDATE(), 108)", conn) WHERE LST_DATE = CONVERT(GETDATE(), 107) + ' ' + CONVERT(GETDATE(), 108)", conn)
But for some reason it is not working. Please help!
Hi, The following INSERT query works in all aspects apart from the date value: String InsertCmd = string.Format("INSERT INTO [CommPayments] ([CommPaymentID], [Date], [InvestmentID], [Amount]) VALUES ({0},{1},{2},{3})", FormView1.SelectedValue, txtPaymentDate.Text, ddlInvestments.SelectedValue, txtAmount.Text); The value of txtPaymentDate.Text is "13/04/2006" but is inserted as a zero value (i.e. "01/01/1900"). In additon to replacing {1} with a string, I've tried changing {1} to both '{1}' and #{1}#, both of which are "caught" by my try/catch on the INSERT. What am I doing wrong? Thanks very much. Regards Gary
hi. i'm trying to order my results ascending by date except i'm getting some really weird output. my ouput resembles something like this:
oct 2 oct 3 sep 13 sep 21 sep 22 sep 30 aug 3 aug 5 aug 16
the data is stored in a date field. i use getdate when inserting the date to the database. is there a reason why the dates are showing up weird and not ordering appropriately? thanks for your help.
also, can you not search here any more? i keep getting timeout errors.
I have a table with a single effective date, rather than both a start and stop date. I have to be able to match up this table to another one with service information in it and am not sure how to get the correct record selected.
So in table one I have a personID, effective date, and lots of other fields. There are also multiple records for each personID, so say personID 1 has records with effective dates of 1/1/2007, 6/1/2007, and 1/1/2008.
Table two has personID, Service Date, and lots of other fields.
So if I am looking to match up the effective row from table one to a record in table two with a service date of 8/1/2007, how do I get the db to locate and return the record with an effective date of 6/1/2007, and only this record?
We are using [DATE] [TIME] functions in SQL Server 2000 agent jobs and SQL Server use to translate it to current data and time functions but in SS2005 it is not replacing the functions and we are getting filename as "test_DATE_TIME" whereas we expect "test_20071204_130000" Do we have any new functions as replacement?
Thanks --rubs
Following is the code we are using: declare @name nvarchar(100) declare @name1 nvarchar(100) set @name1 = 'test_[DATE]_[TIME]' set @name = 'c:ackup' + @name1 + '.bak' backup database test to disk = @name
I'm looking to return certain rows from our db into an SSRS based on a user selected date range using the parameters calendar.
My query/analyzer returns all required fields/rows, but how do I pull the specific rows, (that are based on a date range that the user enters),into the report? I've tried expressions, and vb functions to no avail. The users will be using the calendar parameter to select date ranges .So far the reports pull in all rows from my query.
I have a table that has a date field that can't be null. When a new record is created, if a date is not passed in, I want the default to be the current date. How can I set that? I tried Now, Today, GetDate, etc. Diane
I have 3 dates one of them could be NULL . I do not want my min to display it as NULL.Below is my script. Is there a way I could do it?
select Order_id, customer_id, date_1, date_2, date_3 into #temp1 from ##Temp_dates (nolock) Select Case when (date_1 < date_2 and date_1< date_3) then date_1 when (date_2< date_1 and date_2< date_3) then date_2
Caseinfo shows when a particular case entered and exited a particular project. If the project hasn't ended yet, then the end date is NULL.
Steps shows the steps the case has gone through and the dates of those particular steps.
I need to join the tables to show the steps the case went through during a particular project, but I'm having trouble with the NULL values in the end dates.
If I join the tables so that the step date is between the start and end dates of the project, then I get no step information for the cases where the end date is NULL (that is, where the project hasn't ended yet).
Does anybody have any ideas?
Here are my tables, the query that shows the main idea (with the wrong result), and my expected results.
insert @caseinfo select 10, '2006-12-23', '2006-12-27' union all select 20, '2006-12-23', NULL union all select 30, '2006-12-23', NULL union all select 40, '2007-1-15', '2007-3-4'
insert @steps select 10, 1, '2006-12-24' union all select 10, 2, '2007-1-3' union all select 10, 3, '2007-2-5' union all select 20, 1, '2006-12-26' union all select 20, 2, '2007-1-7' union all select 20, 3, '2007-1-9' union all select 30, 1, '2007-1-14' union all select 40, 1, '2007-1-23' union all select 40, 2, '2007-3-2' union all select 40, 3, '2007-4-16'
--- the main idea (with the wrong results)
select * from @caseinfo c left join @steps s on s.caseid = c.caseid and s.stepdate between c.startdate and c.enddate
insert @expresult select 10, '2006-12-23', '2006-12-27', 1, '2006-12-24' union all select 20, '2006-12-23', NULL, 1, '2006-12-26' union all select 20, '2006-12-23', NULL, 2, '2007-1-7' union all select 20, '2006-12-23', NULL, 3, '2007-1-9' union all select 30, '2006-12-23', NULL, 1, '2007-1-14' union all select 40, '2007-1-15', '2007-3-4', 1, '2007-1-23' union all select 40, '2007-1-15', '2007-3-4', 2, '2007-3-2'
How can i write a condition for like isdate(Fields!DueDate.value)
I tried isdate but i am getting an error message. what is the equivalent for isdate in sql server reporting services formula fields or calculated fields expression.
I have an SQL database table that includes a BirthDate field. I would like to have this field as optional when adding a record, but, SQL insists on throwing an exception if the field is null.
I need to be able to add minutes to a datetime value, which only cover working hours.
I have a holiday table as below:
Examples: (dd/MM/yyyy hh:mm) Date..........Description 01/01/2015 New Years Day 26/12/2014 Boxing Day 25/12/2014 Christmas Day 25/08/2014 August Bank Holiday
Our Business hours are 08:00-18:00 Mon-Fri (unless the day is in the holiday table)
I have tried to create a function to do this (fn_pp_AddMinutesWithinWorkingHours(@StartDate,@Minutes)) but I am unable to come up with a solution which factors in everything correctly.
Hi I would like to return data for working days only. This will need to exclude holidays.For eg In the Month of August we have 31 Days and every 1st day of 1st week is holiday.So my output should retrieve me 31-4=27 . Any ideas?
I'm a SQL newbie, and I'm trying to write a report that returns records based on a beginning and end date that the user supplies. But when I run the query and supply the dates (begin 11/29/2007 / end 11/30/2007, for example), I'm only getting back one record, when there should be at least 3. It appears that my query is ignoring the =, and only returning those records that have a date > or <, not <= or >=.
I was told that it's possible that the time needs to be converted to UTC as well, but I'm not sure how to do that ( I tried, but I really don't know what I'm doing so I commented it out)... Can someone offer some guidance on how to get all the records to show up? I've pasted my query below, thanks in advance!
FilteredContact.new_referred_by, convert(varchar(10),FilteredContact.createdon,101) as Date--, SELECT GETDATE(FilteredContact.createdon) AS CurrentTime, GETUTCDATE(FilteredContact.createdon) AS UTCTime
Hi, I need to calculate the number of working days from a date backwards. For example 2 working days before Thursday would be the Tuesday (as a basic example)
I use the following code and a Calendar table to calculate the working days from a date but can anyone help with reworking this query to do the reverse
declare @WorkingDate as datetime
SELECT @WorkingDate=dt FROM tblCalendar AS c WHERE (@WorkingDays = (SELECT COUNT(*) AS Expr1 FROM tblCalendar AS c2 WHERE (dt >= @StartDate) AND (dt <= c.dt) AND (IsWeekday = 1) AND (IsHoliday = 0))) AND (IsWeekday = 1) AND (IsHoliday = 0)
-- Return the result of the function RETURN convert(varchar(12),@WorkingDate,106)
I am update/inserting records threw a web form in vb.net. I need to insert 'NULL' into my microsoft sql server database. I am not talking about the below line of code where website is the name of my paramater. If i do that it will just place a blank into that field in the database. If i dont enter anything into that textbox I want it to to say NULL in that field. So if I go into the actual table in the SQL Server Management Studio and look at the website field of the recored I just added or updated and did not type anything into the web site textbox it needs to say NULL. I also tried the second line of code but that places a single quote in front and behind NULL. So the field will have the value 'NULL'. website.value = txtwebsite.text.tostirng if txtwebsite.text ="" then website.value ="NULL" end if The reason why I need the NULL there is because I bind the website filed to a hyperlink template in a gridview. The actual text of the hyperlink is bound to PAYER which is a name of a insurance payer but the navigateto is bound to the website field. If i do not enter any data into the website field and it stays as NULL, then when my gridview is loaded, payers that dont have a website will not be underlined and user wont have the option to click on them since there is no value for the navigateto. But if i use my form to update/add a payer and leave the website textbox blank in puts a blank into that field in my database and when it loads that new row into the gridview the PAYER is underlined and u can click on it but it will just take u to the web site is unavailable page. So is there anyway to actaull have NULL placed into a filed and not just blank space
