Inconsistant Row Counts When Selecting Data By Dates HELP!
Feb 28, 2000
Hi,
I currently think Im going mad!!
I have a large table (2+Million records, 2000+ new per day). If I want to count the records in one month, I could do :-
Select Count(*) from Table1 where Added_Date between '1999-12-01'
and '1999-12-31'
or
Select Count(*) from Table1 where Added_Date >= '1999-12-01' and
Added_Date <= '1999-12-31'
For these two above, I get the same result.
HOWEVER!!
If I then do:-
Select Count(*) from Table1 where Added_Date between '1999-12-01 00:00:00'
and '1999-12-31 23:59:59'
or use the >= and <= operators, the result is larger.
If I then do :-
Select Count(*) from Table1 where Added_Date between '1999-12-01 00:00:00.000' and '1999-12-31 23:59:59.999'
or use the >= and <= operators, the result is larger still but i believe this including more rows than there actually is?.
I can get over the problem programatically using Convert to truncate to a day, month or year however, I don't understand why the results are different.
Any Ideas as to why this is happening, A'm I being stupid!!!!!!!
(PS Added_Date has a non_clustered index which has been rebuilt twice and DBCC finds no errors)
For some reason this is just not "clicking" with me and the longer I stare at it the more I overcomplicate things and then I just confuse myself further...
Provided this relation showing where "pkey" and "skey" met on "ServiceDate":
I need to select out a list of distinct pkeys and skeys only when there was no meeting between the two in November 2005. In other words, this query would produce only one record - the starred record - when run against this sample table. This is because even though, for example, skey 124 / pkey 2 has an entry outside the desired range, it also has one inside the desired range. The same goes for the record outside our range for 123 and 2 - it also has a record inside our range.
At this point, I've come to the conclusion that I can first select all the distinct pkeys and skeys where the servicedate is not in 11/2005 then join it to a selection of distinct pkeys and skeys where the servicedate IS in the desired date range. Does that seem like the most straightforward way through this?
I don't get the impression that this is that complicated a problem, but it's one of those deals where I goofed up somewhere along the line, and now I think I'm really overthinking the problem, so I'd be much obliged if someone could give me a hearty slap to clear the ol' noggin.
What I am trying to do: Obtain attendance percentages for schools for the last five days. The outcome would look like this:
DISTRICTGROUPING, SCHOOLNAME, 5 DAYS AGO PCTG, 4 DAYS AGO PCTG, 3 DAYS AGO PCTG, 2 DAYS AGO PCTG, 1 DAY AGO PCTG I am using nested subqueries for each day as follows: (total enrollment-total absent/total enrollment) ,( ((SELECTCOUNT(*)--GET TOTAL ENROLLMENT COUNT FOR SPECIFIED DATE
[Code]....
The query works with the following exceptions:
My issues are:
1. Avoid the "division by zero" error. This can occur if a school is closed for a day or if a smaller school has no absences for a day.
2. Avoid weekend dates. I need the query to display only weekdays
3. Currently I am using "PERCENTAGE 5: as a column header whereas I need the actual date as the header.
I need to be able to select records based on dates that are before a certain date. That bit's easy, my problem is that this certain date needs to be the current date. Any body be able to help?
Hello Forum, I am have posted questions regarding selecting a series of dates and am still having trouble doing so. I have been using vwd to build a website, and now would like to retrieve data from access and display a weeks worth of information at one time from selecting a column of information from the data base. I have used this section of code to do the required function. 'SELECT OrderId, CustomerId, Price FROM Orders WHERE OrderedDate BETWEEN DATEADD(d, -7, GETDATE()) AND GETDATE(), I have replaced these variables with my own, and keep getting an error message 'Undefined function 'GETDATE' in expression', I have tried many different functions to get it to work. Any ideas? Thanks Forum, Tim p.s. thank you todd for replying to my first question!
I am having a problem in outputting the last two dates that a bill has been sent out.
Background: A customers recieves a bill 4 times a year. The dates for issuing these bills are not fixed and I dont know the date that bills are usually sent out.
The database that I am using stores all of the dates that a bill would have been sent out.
Issue: A customer recently requested to see the dates of last 2 bills along with their value.
I know that you can view a customer last date by using the following statement.
Select max(issuedate)LastBill from statements
but i don't know how i could output the last 2 bills that were issued
I have two tables a stock table and a price table and I want to select the correct price for the Stock Date.
Problem is sometimes there is a promotion date in the price table between the live dates so the rows double up. Below is my sql but I get over 17,000 rows when it should be about 16,964.
I will post up the table and data.
SELECT a.[Company] ,a.[ProductID] ,a.[ColourSize] ,a.[StockDate] ,a.[Quantity] ,b.[Ticket Price] FROM[Stock_Ledger] a LEFT OUTER JOIN [Product_Prices] b ON a.[Company] = b.[Company] AND a.[ProductID] = b.[ProductID] AND a.[ColourSize] = b.[ColourSize] AND a.[StockDate] BETWEEN b.[StartDate] AND b.[EndDate] ORDER BY a.[StockDate],a.[ProductID],a.[ColourSize]
HiI have a table in my database called 'tblUsers'It contains usernames and a few columns of data.One of them in 'birthday'it is in the format dd/mm (ie 28/04 is 28th of april)it is always 5 characters longIts data type is char in my db.Now I try this<asp:SqlDataSource ID="SqlDataSource8" runat="server" ConnectionString="<%$ ConnectionStrings:IntranetConnectionString %>" SelectCommand="SELECT DisplayName FROM [tblUsers] WHERE ([Birthday] = @ShortDate)"> <SelectParameters> <asp:ControlParameter ControlID="Calendar1" Name="ShortDate" PropertyName="SelectedDate" Type="string" /> </SelectParameters> </asp:SqlDataSource>where the selected date from a calendar control is used.Now it works when the table has a Date column which is off type DateTime but how would I modify it to work like I want?Thanks!
Hi, I was wondering if anyone can help me write a SELECT statement to return all records (rows) based on whether they fall within two dates. For example, consider this table:
Code Snippet --DROP TABLE #Records CREATE TABLE #Records (RecordID INT PRIMARY KEY NOT NULL, StartDate DATETIME, EndDate DATETIME) INSERT INTO #Records VALUES (1, '2008-05-01', '2008-05-12') INSERT INTO #Records VALUES (2, '2008-05-08', '2008-05-12') INSERT INTO #Records VALUES (3, '2008-05-19', '2008-05-22') INSERT INTO #Records VALUES (4, '2008-05-22', '2008-05-23') INSERT INTO #Records VALUES (5, '2008-05-26', '2008-06-01') INSERT INTO #Records VALUES (6, '2008-05-28', '2008-06-01') SELECT * FROM #Records
I want to return the RecordID for any row which span this week. I've tried the simple approach of using WHERE GETDATE() BETWEEN StartDate AND EndDate but this doesn't produce the desired results. For example, RecordID 4 spans this current week but is not returned (obviously) with this approach.
The idea is to show which events (rows) are coming up this week and next week. Eventually the data will be used to populate an SSRS report.
Hello. I need to create a page with asp 3 and sql server 2000 that lists all the records in a table that match a date criterion, but when doing so I get an error "Error Converting datetime from character string"... I've tried this versions of the query:
Code:
SELECT (...) CONVERT(DATETIME,PAYMENTS_RECEIVED.PYR_DATE,103), (...) FROM RESERVES LEFT OUTER JOIN (...) WHERE (PAYMENTS_RECEIVED.PYR_DATE BETWEEN '20/03/2006' AND '21/03/2006')
and...
Code:
SELECT (...) PAYMENTS_RECEIVED.PYR_DATE, (...) FROM RESERVES LEFT OUTER JOIN (...) WHERE (PAYMENTS_RECEIVED.PYR_DATE >= CONVERT(DATETIME,'20/03/2006',103)) AND (PAYMENTS_RECEIVED.PYR_DATE < CONVERT(DATETIME,'21/03/2006',103))
I also tried adding " 00:00:00 a.m." to the dates to be converted in the second piece of code. If I recall correctly, "103" is the convertion code meaning "dd/mm/yyyy". That is, I expect people to type in a date like "27/03/2006" and get the table records from that date.
Weirdest thing of all is that, when using the query builder of a sqlsource control in Visual Studio Web Developer Express 2005 this following query works just fine as I expect:
Code:
SELECT (...) PAYMENTS_RECEIVED.PYR_DATE, (...) FROM RESERVES LEFT OUTER JOIN (...) WHERE (PAYMENTS_RECEIVED.PYR_DATE >= CONVERT(DATETIME, '20/03/2006', 103)) AND (PAYMENTS_RECEIVED.PYR_DATE < CONVERT(DATETIME, ' 21 / 03 / 2006 ', 103))
Both the server and the DB are the same in all cases, but in the first two I run the query from a (working of other queries) vbscript asp 3 page.
I know that similar posts exist already (I've searched for this before posting), but I can't fix it, at least not with the usual answer on this one (that seems to be using the convert function as in the first piece of code). Thanks in advance!!!
tblCustomers contains a CustomerID that is unique to each customer.
tblMachines contains a list of all machines with a MachineID that is unique to each machine. It also contains the CustomerID number.
tblServiceOrders contains a list of each time each customer was serviced. It contains the ServiceDate, CustomerID, and ServiceOrderNo. But it does not have any information on the machines.
tblMachinesServiced contains a list of each machine that was serviced for each service order. It contains the ServiceOrderNo and the MachineID number.
What I want is to be able to extract a list of machines that were not serviced between 2 dates. What I end up getting is a list of machines that were serviced outside of the date range I provide.
For instance, say machine A was serviced in 2013 and 2015 but not in 2014. And say machine B was serviced in all 3 years. When I try to extract my list of machines not serviced in 2014 I end up with a list that contains machine A-2013, A-2015, B-2013 & B-2015. But what I need is just machine A-2014, since that machine wasn’t serviced in 2014.
I’ve tried several different queries but here is an example:
SELECT tblMachines.MachineID,ServiceMachines.ServiceDate FROM tblMachines LEFT JOIN (SELECT MachineID, ServiceDate FROM tblServiceOrders, tblMachinesServiced WHERE tblServiceOrders.ServiceOrderNo=tblMachinesServiced.ServiceOrderNo ) ServicedMachines ON tblMachines.MachineID=ServicedMachines.MachineID WHERE YEAR(ServiceDate) != '2014'
I understand why it returns the records that it does, but I'm not sure how to get what I want, which is a list of machines not serviced in 2014.
I have three tables: EMP (ID, NAME), EMPDATE (ID, STARTDATE, ENDDATE), YEAR(YEAR)
I would like to get the most recent date within a given year per each EMP? For example, EMPID 1 can be enrolled in many programs, each program has start end dates. I need to list the most recent date an employee was enrolled (max date between START AND END DATE which ever is most recent enrollment) for a given year. For example, for 2014 his/her most recent enrollment should be 10/23/2014 for year 2014 and 2013-10-24 for year 2013.
SELECT ID, EMP.NAME, DTE.StartDate, DTE.ENDDATE, year FROM EMP_DATE DTE join EMP_INFO EMP on EMP.ID = DTE.ID join YEAR YR on YR.YEAR = YEAR(DTE.STARTDATE)
On my SSRS report, I use a date parameter to let the user select a date with the little calendar tool. When a date is selected, I have a small bit of coding run to convert the date to text, because when the report first fires up, the field is populated with "1/1/1900," and I need that turned into a blank character to let the report pull up all rows. So far, all well and good.If someone picks a date, then the report will filter the data on that selected date. Works fine.
But, it appears there is no way to get the calendar tool to go back to allowing ALL dates - so that all records are pulled - except by manually typing in, or selecting it with the tool, 1/1/1900.If I try to clear the field, causing it to use '' as a WHERE criteria (WHERE AdmitDate LIKE '%' + @AdmitDateTxt + '%'), it repopulates the field with the last selected date. So, I guess the question is, how does one tell the calendar tool for picking dates for a date parameter to reset back such that all records are pulled, not just those for a single date, without being required to type in, 1/1/1900? Or, is there some way of telling the date parameter to select all dates?
I have a DTS package that runs once a week. There is a xp_sendmail SQL task at the end that sends emails to our field sales people with a file attachment based on the results of the DTS package. Simple enough.
The problem I have is that the sendmail chokes when the mail task is executed at the end of the package - sometimes. And when it does fail, the DTS step with the sendmail can be executed separately without a problem.
The error message the gets generated is:
MAPI_E_NETWORK_ERROR80040115-2147221227
This does not make sense. If there was a network problem I should still get a message when executing the step that failed 30 seconds prior...not the case.
The other odd thing is that this package has been running fine for about 3 mo with no troubles, but our mail server may have undergone some changes that I am not aware of so...anyway if anyone has any info or has come across this oddness please feel free to share with me what you know.
I am a t a loss here with this one.
Thanks in advance to anyone else with a dented skull that has an answer!
I succesfully did a MSSQL "file" restore of production to a different node yesterday. But failed to apply any transaction logs, it complained that one of the files have not been restored. On further investigation I found that one of the files are missing in sysfiles, but the file is in sysaltfiles.
This SQL statement does not return the same number files. SELECT * FROM <DB>..sysfilesSELECT * FROM master..sysaltfiles WHERE dbid= DB_ID('<DB>')
sp_helpdb '<DB>' gives the same result as sysfiles.
I'm looking to get counts on historical data where the number of records exists on or after May 1 in any given year. I've got the total number of records for each year worked out, but now looking for the number of records exist after a specific date. Here's what I have so far.
SELECT p.FY10,p.FY11,p.FY12,p.FY13,p.FY14,p.FY15 FROM ( SELECT COUNT(recordID) AS S, CASE DateFY
On SQL Server 2000. IBM X series, dual 2GHz Xeon processors, 3GB RAM, RAID 5 DB array and separate Mirrored drive for OS, Windows 2000 Server.
Note: I should have moved the log files to the mirrored volume - I only just noticed it wasn't like that ... oops.:o It only has the OS and backup files (different logical volumes).
Problem: I have a Bill of Material system. It has a batch (Stored Procedure) that explodes Order Line Items. Each line has about 40 components.
The SP has 5 major steps to explode the Assembly, figure out colors/sizes to get the actual part numbers, assign quantities, update flags on the line item table (that has 3,500,000 rows but is not a clustered index - fill factor 85% on the unique autonumber index I use for the updates). The SP is jam packed with User Function calls, sub-Stored Procedures, and (yes) some cursors (on small declared temp tables created for each Order Line processed).
The execution plan for the whole batch of 100 is humongous - like 1000 pages, however nearly all steps are about 16 - 40 milliseconds to execute.
It normally takes 13 seconds to process 100 line items (3900 assembly rows created). However; about every 20th run, it takes 2 or 3 minutes ON THE VERY SAME LINE ITEMS. No programming changes! Run back-to-back, or with a minute or two delay. Then running it again, back to 13 seconds. Sometimes it takes 25 or so seconds, but that oddball 3 minutes is a killer.
I put some timing INSERTs into a temporary log file to localize the problem.
So; here's the REALLY weird thing. The part that experiences the intermittent 2 minute delay is a VERY SIMPLE call to a SP that INSERTs to the tbBATCHs table and gets the identity and passes it back with an Output variable. The tbBATCHs table only has about 8 columns. Nobody else uses it so it's not locking. It has an "If Exists" selection following the Insert to see if another batch is in progress not yet flagged as complete, but's not the issue because it's never true (hard coded values for testing forces this).
I have a Standby Server (duplicate config of main server) so I ran it there. Same issue.
If I loop 100 times on the tbBATCHs INSERT SP, it is pretty quick (like 2 seconds for all 100).
It's never on the first run, so I think it may be some sort of Log File catch-up.
Also; I DO NOT have Transaction Logging in place yet.
I have a table that seems to have a bad index. When I do the followingquery I get inconsistant and needless to say incorrect results.select count(*) from mytable where mycolumn = 1If I remove the index from "mycolumn" the query works correctly. If Iadd the index back (even with a new name etc...) it doesn't workright.Has anyone ran into this? or does anyone know how I can fix thisproblem?It seems that removing the index is not really removing everythingbecause when I add a new one I get this same problem... btw, this isisolated to this column on this table. all other indexes within thedatabase are fine.Any help would be appreciated.Thanks,dharper
The documentation for sp_trace_generateevent states that the following arguments are available:
Arguments [ @eventid=] event_id Is the ID of the event to turn on. event_id is int, with no default. The ID must be one of the event numbers from 82 through 91, which represent user-defined events as set with sp_trace_setevent. [ @userinfo= ] 'user_info' Is the optional user-defined string identifying the reason for the event. user_info is nvarchar(128), with a default of NULL. [ @userdata= ] user_data Is the optional user-specified data for the event. user_data is varbinary(8000), with a default of NULL.
@userinfo is stored in the textdata column, which after inspecting sys.trace_columns is of type text with a max size of 1073741824.
@userdata is stored in the binarydata column whose type is image with a max size of 1073741824.
I am attempting to build a stack trace of sorts that will capture detailed information about the run-time code executed when an error (contained within a try/catch) occurred.
The sql returned from dm_exec_sql_text goes well beyond 8000 and is getting truncated.
I haven't found any hot-fixes for SQL Server 2005 that addresses this issue. Has anyone else bumped into this limitation or found any explanation on the inconsistency between the stored procedure€™s arguments and the column types that the values are stored in?
I am pretty new to SSIS. I am trying to create a package which can accept data in any of several formats. i.e. CSV, Excel, a SQL Server database/table and import the data into my destination database.
So far i've managed to get this working OK. However I am now TOTALLY stuck. I'm currently trying to just concentrate on the data sources being a CSV (using a Flat File Data Source) and/or an Excel Spreadsheet.
I can get the data in and to my destination using a UNION ALL component and mapping the data sources to it so long as both the CSV file and the Excel spreadsheet exist.
My problem is that I need my package to handle the possibility that only the CSV file might exist and there is no Excel spreadsheet. In which case i'd like the package to ignore the Excel datasource completely. Currently either of my data sources do not exist I get errors and the package terminates.
Is there any way in SSIS that I can check all my data sources to see which ones exist (i.e. are valid). If they exist I want to use them. If it doesn't exist i'd like to disgard it (without error - as long as there is a single datasource the package should run)
I've tried using the AcquireConnection method in a script task on each of my connections, hoping that it would error if the file/datasource did not exist. It doesn't though (in the case of an Excel datasource it just creates a empty excel file for me).
The only other option I can come up with are to have seperate packages depending on the type of data we want to import and then run a particular package depending on the format of the source data. This seems a bit long winded. I am pretty sure I must be able to do what I want to achieve but I can't work out how.
I'll be grateful to anyone who can send me any tips/hints/links on how I can achieve this.
I have a scenarios where if I execute select * from tbl it should display the all the records without waiting to release any lock. For example suppose I have one table called tbl and one session is updating one records and not committed yet and in other session if i execute select * from table I can see all the records, for that records it can show me older version. but my select statement should not wait to commit another session and also it should not show the modified data.
Hello . Sometimes when i try to select data from a table (from a selected database) using SQL Query Analyzer (for exemple) i receive an error message : "The Object XX does not exist" . But when i prefix it by the Owner it work .
I've got a big problem that I'm trying to figure out: I have an address table out-of-which I am trying to select mailing addresses for companies UNLESS a mailing address doesn't exist; then I want to select the physical addresses for that company. If I get multiple mailing or physical addresses returned I only want the most recently edited out of those.
I don't need this for an individual ID select, I need it applied to every record from the table.
My address table has some columns that look like: [AddressID] [int] [LocationID] [int]
AddressID is a primary-key non-null column to the address table and the LocationID is a foreign key value from a seperate Companies table. So there will be multiple addresses to one LocationID, but each address will have it's own AddressID.
How can I do this efficiently with perfomance in mind???
Plugging away at my little message board that I am working on, I have hit another SQL snag. I am trying to select a list of all posts in a thread. I have to get each post, the name of the poster (which comes from a different table - referenced by userid), as well as some profil information, from a 3rd table (also referenced by the userid).
Iam farely new to this so sorry for the newbie question.. but how do you select all data from one table and insert that data into the same table but in another sql database.
I was wondering if this is possible I have to be able to just select the number before the '-' in acolumn which is formatted like 123-456 so I just need the the 123 part.
I am having problem in selecting the data from my datalist. Here is teh sample code <asp:datalist id="dlAttrName" runat="server" OnItemCommand="dlAttrName_SelectData" DataKeyField="attrID"> <ItemTemplate> <asp:LinkButton ID="lbSelect" Runat="server" CommandName="Select" style="display:none">Select</asp:LinkButton> <%# Container.DataItem("attrDef1")%> </ItemTemplate> </asp:DataList> Private Sub dlAttrName_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataListItemEventArgs) Handles dlAttrName.ItemDataBound If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then 'Add eventhandlers for highlighting 'a DataListItem when the mouse hovers over it. e.Item.Attributes.Add("onmouseover","????") e.Item.Attributes.Add("onmouseout", "????") 'Add eventhandler for simulating 'a click on the 'SelectButton' e.Item.Attributes.Add("onclick", ?????????????????????, String.Empty)) ??????????????????? this should have something like this Me.Page.ClientScript.GetPostBackEventReference(e.Item.Controls(1) But I am not able to get the ClientScript option, I don't know which namespace should I import?
I don't know whether I am right or not. Its urgent please reply back soon,any help will be useful. Thanks!!!!!!!
Hi,I have a message system, where people insert their message to the database, and others pick up their messages by selecting messages that have their username as the reciever ID.I have just intoduced bulk message sending - sending to multiple users. This requires many usernames being entered into the recievername column, seperated by a comma.Is there a way to select messages if the column name contains their username, rather than is their username? Because there may be more than one name, I would like everyone that has their name in the column to be able to retrieve the message, even if they arent the only reciever..Please ask if more explanation is needed!Thanks,Jon
I have three tables that are joined together to retrieve a piece of data.Table One has the columns pid1(PK), idTable Two has the columns pid1, qid1, idTable three has columns qid1, question, answerHere is my sql statement:SELECT Table1.pid1, Table2.qid1, Table3.Question FROM Table1 JOIN Table2 ON Table1.pid1=Table2.pid1 JOIN Table3 ON Table2.qid1=Table3.qid1 WHERE Table1.pid=...(N)I put an elipsis because I'm stuck on how to proceed from here. See I need to randomly select a value from column pid1 in table1 then use this value to replace N in the sql statement, then have the statement run and randomly return exactly one piece of data instead.Is this possible? How can you randomly get one piece of data from joining three table without a WHERE CLAUSE.
