Hello,Can someone please help me with a query?The table looks like this:BookedRooms===========CustomerID RoomID BookDateID1 1 200507011 1 200507021 1 200507031 1 200507091 1 200507101 1 200507111 1 20050712Desired result:CUSTOMER STAYS==============CustomerID RoomID ArriveDateID DepartDateID1 1 20050701 200507031 1 20050709 20050712Basically, this is for a hotel reservation system. Charges varynightly, and customer changes (shortening/extending stay, changingrooms, etc) happen quite often. Therefore, the entire stay is bookedas a series of nights.The length of the stay is never known, so it needs to be derived viathe Arrive and Depart Dates, based on the entries in the table.Notice, customers often stay in the same room, but with gaps between,so a simple MIN and MAX doesn't work. The output needs to showconsecutive nights grouped together, only.I've researched this quite a bit, but I just can't seem to make itwork.Any help would greatly be appreciated.Thanks!
I have a table full of service invoice records. Some of the invoices are continuous, meaning that there may be an invoice from 01-16-2015 through the end of that month, but then another invoice that starts on feb 1 and goes for 6 months.
I want to only pull the most recent. Keep in mind that there may be other invoices in the same table for a different period. An example might be:
have a table with students details in it, i want to select all the students who joined a class on a particular day and then i need another query to select all students who joined classes over the course of date range eg 03/12/2003 to 12/12/2003.
i have tried with the following query, i need help putting my queries together select * from tblstudents where classID='1' and studentstartdate between ('03/12/2004') and ('03/12/2004')
when i run this query i get this message
Server: Msg 242, Level 16, State 3, Line 1 The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.
the studentstartdate field is set as datetime 8 and the date looks like this in the table 03/12/2004 03:12:15
I have a sqlDataSource control that has its select command and parameters set dynamically. One of the parameters is a date, which should be in smalldatetime format (ie, 12/22/2006). Obviously, using SQL Server, the data is stored with both date and time. The problem is, I cannot get any data selected. I initially thought that I needed to tell it to only look at the date and not the time, but from what I have seen this should work. Here is the pertinent code. dim seldate as datetime selDate = Session("ChosenDate") Dim SelCmd As String = "SELECT [PatientName], [AssignedTo], [CPT], [CPT2], [HospitalID], [RoomNbr], [ACType], [TxDx1], [TxDx2], [MRNbr], [Notes], [PatientID], [PCPID], [ResidentID], [Status], [CaseID], [AdmitDate], [crtd_datetime] FROM [DailyBilling] WHERE ([crtd_datetime] = @crtd_datetime) and ([AssignedTo] = @AssignedTo) and ([HospitalID] = @HospitalID) ORDER BY [PatientName]" SqlDataSource1.SelectCommand = SelCmd SqlDataSource1.SelectParameters.Clear()
Dim parFilterProvider As New ControlParameter() parFilterProvider.ControlID = "ddlProvider" parFilterProvider.Name = "AssignedTo" parFilterProvider.Type = TypeCode.String SqlDataSource1.SelectParameters.Add(parFilterProvider)
Dim parFilterHospital As New ControlParameter() parFilterHospital.ControlID = "ddlHospitals" parFilterHospital.Name = "HospitalID" parFilterHospital.Type = TypeCode.String SqlDataSource1.SelectParameters.Add(parFilterHospital)
Dim parFilterStatus As New Parameter() parFilterStatus.Name = "crtd_datetime" parFilterStatus.DefaultValue = selDate.ToShortDateString parFilterStatus.Type = TypeCode.DateTime SqlDataSource1.SelectParameters.Add(parFilterStatus)
I am trying to select all records added between 2 dates that the user inputs into a form and am having problems. I had this working no problems with asp but can't seem to get it working with .net. BTW I am using SQL Server and Visual Studio.
The asp.net code I am trying to use is:
Me.SqlSelectCommand1.CommandText = "SELECT news_title, news_date, news_type, news_link FROM news WHERE (news_type = 'news') AND (news_date BETWEEN CONVERT(DATETIME, '"" & startdate & ""', 102) AND CONVERT(DATETIME, '"" & enddate & ""', 102))"
....

Dim startdate As DateTime startdate = Request.Form("date_from")
Dim enddate As DateTime enddate = Request.Form("date_to")
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 a form that's filtering search results and porting to a gridview. The drop down is selecting from the date column of SQL, but i want it the default value to show all dates in the gridview. In a normal string field, you can just use "%", but a datetime field won't take this. What can i use to show all dates?
Hi all,Right now I have this SELECT statement:SELECT MUSIC_PK, MUSIC_TITLE, MUSIC_TITLE2, MUSIC_ORIGINAL_SINGER Now I want to add a second SELECT statement (same as above, but with an additional column) if the record was added within the 10 days (while still select other records, I just need to select an additional column). How would I do that? The additional column that I want to select is called MUSIC_NEW (so I can display if the record is new within 10 days.) I have a column in my table named DATE_ADDED, how do I go to calculate if it's within the 10 days since the day it was added to the current time?Thank you very much,Kenny.
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 want to be able to create a select query on the above table. The table will show ID, PersonID (PID), From and to date, and code. If the code is X then the next €˜from record€™ should be the same date as the €˜to date€™. If the code is E then the next €˜to€™ date can be anytime after the previous €˜to€™ date. I want to be able to report on all record where there is a day difference between the previous €˜to€™ date. I.e. ID 4 and 7 €“ the previous records both have an X and there is at least a days difference between the dates.
I have a table with addresses and activity dates. I need to be able to retrieve the past 3 activity dates and see if the first and last occurred within 15 days. If so, I need to flag them.
Using max date gets me the last date but not the previous two. I was trying to use top 3 in desc order and that didnt seem to work either.
Hello. I'm having troubles with a query that (should) return all therecords between two dates. The date field is a datetime type. The db isSQL Server 2000. When I try thisSELECT RESERVES.RES_ID, PAYMENTS_RECEIVED.PYR_ID,PAYMENTS_RECEIVED.PYR_VALUE, PAYMENTS_RECEIVED.PYR_DATE,CUSTOMERS.CUS_NAMEFROM RESERVES LEFT OUTER JOINPAYMENTS_RECEIVED ON RESERVES.RES_ID =PAYMENTS_RECEIVED.RES_ID LEFT OUTER JOINCUSTOMERS ON RESERVES.CUS_ID = CUSTOMERS.CUS_IDWHERE (PAYMENTS_RECEIVED.PYR_DATE >= '2006-03-20 00:00:00') AND(PAYMENTS_RECEIVED.PYR_DATE < '2006-03-27 00:00:00')on a "query builder" in visual studio, I get the results that I want.But when I use exactly the same query on an asp 3 vbscript script, Iget no results (an empty selection).I've done everything imaginable. I wrote the date as iso, ansi, britishformat using convert(,103) (that's how users will enter the dates),i've used cast('20060327' as datetime), etc. But I can't still get itto work. Other querys from the asp pages work ok. Any ideas?thanks a lot in advance
I have a report that uses several filters including a from and to date filter, I have a field named TimeLastMod which is a Timestamp. I am extracting the From and To dates from this field using Select format(TimeLastMod,'MMM') as FromMonth,format(TimeLastMod,'MMM') as ToMonth From Eventlogs syntax.
These I pass on to a parameter and eventually to a tablix filter in an between opeartion. When I run the report, the records returned by the report is not what is expected as it sometimes returns an extra months data e.g., using between Aug and Sept will return october data as well.
Does anyone know how many consecutive users can be logged into a MSSQL database? I have a database online and need to know how many users can be logged on at a time. someone told me 150 users and others say 200 and stillothers say it's unlimited based on licensing. I tried Microsoft's homepage but got nothing so please don't suggest it. (I spent two hours there)
Suppose that N users are executing the code, one independent of the other, in the same time and they both commit the transaction at the same time. Can I suppose that the rows inserted in the table by one user will be consecutive?
Hi,I'm trying to insert records from one table into another table. The destination table has a ROWID field which cannot be an identity key, but needs to 'act like' an identity key and have its value populated with (Max(ROWID) + 1) for each row added to the table.To my thinking, simply using (Max(ROWID) + 1) in my SELECT statement will not work as it will only be evaluated once so if I am adding 1000 records and Max(ROWID) is 1234, all 1000 entries will end up having a ROWID of 1235.Is there a way to accomplish this?Thanks
Hi, I am in need of a query which would find the same customer coming in for three or more consecutive dates. To elaborate
I have a details table where I capture the following details
CustID, DateofPurchase, PurchaseDetails
I need a query to find how many customers have come in everyday consecutive day and count of the same for the a given period, say a month. Can anyone help me with a query for the same.
I work for a charitable organization, am new to this form (and sql programming) and trying to create a flag for unique records indicating the number of consecutive years a donor has given.
I have create a sample db idenifying donor, giving year and total pledges with multiple donor records existing for multiple years having donated.
INSERT INTO mygifts06 (Id,Gift_yr,Pledges) SELECT 155758,2005,15.00 UNION ALL SELECT 155759,2004,25.00 UNION ALL SELECT 155758,2004,40.00 UNION ALL SELECT 155757,2005,100.00 UNION ALL SELECT 155758,2002,30.00 UNION ALL SELECT 155758,2001,120.00 UNION ALL SELECT 155755,2003,15.00 UNION ALL SELECT 155758,2006,80.00 UNION ALL SELECT 155757,2003,65.00 UNION ALL SELECT 155759,2005,400.00
For the above dataset, I am trying to create the following output
I am using the following query (which works fine):
select min(timex) as start_date ,end_date ,entityid ,entityname ,locationid
[code]....
However I would like to not use the delta (it takes effort to calculate and populate it); instead I am wondering if there is any way to calculate it as part / whilst running the query.
Problem 2
I have the following table which shows the location of different people at 1 hour intervals
I'm trying extract a count of consecutive numbers, or "unbroken" years inthis case, at any particular given time.For example (simplified):CREATE TABLE #Customers(CustNo INT,YearNo INT,IsCust CHAR(1))INSERT INTO #Customers (custno, yearno, isCust) VALUES (999, 2006, 'Y')INSERT INTO #Customers (custno, yearno, isCust) VALUES (999, 2005, 'Y')INSERT INTO #Customers (custno, yearno, isCust) VALUES (999, 2004, 'Y')INSERT INTO #Customers (custno, yearno, isCust) VALUES (999, 2003, 'N')INSERT INTO #Customers (custno, yearno, isCust) VALUES (999, 2002, 'N')INSERT INTO #Customers (custno, yearno, isCust) VALUES (999, 2001, 'Y')INSERT INTO #Customers (custno, yearno, isCust) VALUES (999, 2000, 'Y')SELECT * FROM #CustomersCustNo YearNo IsCust----------- ----------- ------999 2006 Y999 2005 Y999 2004 Y999 2003 N999 2002 N999 2001 Y999 2000 YIn 2006 CustNo 999 would have been active for 3 years, 2004 for 1, 2001 for2, etc. Ideally I'd feed it a single year to lookupI'm resisting the urge to create cursor here -- anyone have any hints?....Chris.
Hi everyone, I'm hoping someone can help me with some sql statements. I have a temp table that contains 30 dates that a student has missed in the last year. I also have a holiday table of when training was not available. I want to find out if there are 6 consecutive days missed excluding weekends and holidays (from the holiday table). I know this is some nasty looping statement but I can't get my brain around it. I would like do this in a stored proc but I could use C# if necessary. Thanks in advance, Jessica
From individual event logs I have generated a table where arrivals and departures at a location are registered per device. As there are multiple registration points, there might be multiple consecutive registrations per location. If this is the case I need to filter those out and have one registration per location and in the result I need to get the earliest arrival and the latest departure of these consecutive rows.
So as long the field LocationID is the same in the next row, it needs to be grouped.
I have added the rows Grp1, Grp2, Grp in an attempt to get an unique grouping number with the following script in the select statement:
,ROW_NUMBER() OVER(PARTITION BY DeviceID ORDER BY logID) AS Grp1 ,ROW_NUMBER() OVER(PARTITION BY DeviceID, LocationID ORDER BY logID) AS Grp2 ,ROW_NUMBER() OVER(PARTITION BY DeviceID ORDER BY logID) - ROW_NUMBER() OVER(PARTITION BY DeviceID, LocationID ORDER BY logID) AS Grp
By subtracting Grp2 from Grp1 (Grp = Grp1 - Grp2) I hoped to get an unique group number for each set of equal consecutive locations, however the Grp2 column does not restart from 1 each time the LocationID changes: Grp2 in line 7 should have been 1 again, but it is 2 because this is the second row with LocationID = 3 in the list.
I am using the following query (which works fine):
select min(timex) as start_date ,end_date ,entityid ,entityname ,locationid
[code]....
However I would like to not use the delta (it takes effort to calculate and populate it); instead I am wondering if there is any way to calculate it as part / whilst running the query.
Problem 2:I have the following table which shows the location of different people at 1 hour intervals
I have a table with 3 columns: Item# | Date | ItemAmount. Everyday there is a number of transactions entered. An Item# can only be entered once par day (if it has occurred that day).
What I want to do is to : retrieve the number of total days where an Item has been entered for more than 2 consecutive days (for the month).
Example: if item I022 has been entered Monday and wed, then ignore, but if it's been entered Mon, Tues then return 2, if Mon, Tues, Wed then return 3 because the days are consecutive.
