Checking Records From Database For Consecutive Year
Apr 23, 2014
I am fairly new to SQl and PHP and have a question. I have a database that we enter in when a person buys a season ticket for our baseball team. I want to check and see who bought in 2013 but has not yet bought in 2014. How do I do that?
THID is the ticket holder ID and there is a year. I can do the select * from Passes where Year = '2014' and get everyone who has bought in 2014. How do I compare that with the 2013 and show people who have not bought yet in 2014?
With this - Ticket holder 21 has bought in both years so I wouldn't want his name to come up. I would want to see that ticket holders 15 and 10 haven't yet bought in 2014.
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
Rajarajan writes "Kindly don't ignore this as regular case. This is peculiar. I need to delete one of duplicate records only if they occurs consecutively. eg.
1. 232 2. 232 3. 345 4. 567 5. 232
Here only the first record has to be delete. Kindly help me out.
Hi every one, I have a database table and currently users may retrieve records for a specified date range by providing the start and end dates and then records between those dates provided are retrieved. For example if users wanted to view all records entered in april, they would have to select 04/01/2007 as the start date and then 04/30/2007 as the end date. The records for april would then be displayed in a gridview. How can configure my sql query such that instead the user selectes a month from a dropdownlist of 12 months. I would love a user to just select the desired month from a list instead of selecting start and end dates. Eg if they are intrested in a report for june, then they should just select june from the list instead of specifying the start and stop dates. HOW can i achieve this.
i m stuck up with a problem...actually i dont have much experience in database line....i m new to this line....i have recently joined the job & this problem is like a test of me....if i will be able to give the solution then everything is fine otherwise i will be fired & im not in a condition to leave this job as this is my first job in software development....i have got this chance with lots of difficulty....so please help me if u can...
the problem is....>> i m using a procedure to check the duplicatye records by using string comparison against address of persons..allover the country....
i m using SQL server 7.0 i have a single table(name of table is DATA) which contains 350000 records( i mean address entries) there are about 35 columns but i have to check duplicate records only against address field...for that first of all i remove special characters from the address field.....then i compare first 20 characters for duplicate entries...
for this i m generating another table(name of another table is RESULT)...
how the logic works...initially the data table contains the records but the result table is totally blank....first of all i pick first entry of address from DATA table then...check it with the entry in RESULT table if the entry exists... it compares the address if the record is same then it generates a refference of this address and make an entry....means a refference of that entry....(as far as very first record is concerned there will be no entry in the RESULT table so it will enter the address over there...then it picks up the second record...checks it in the RESULT table...now this record will be compared with the one & only entry in the RESULT table....if the entry is same then the refference will be entered... otherwise it will be entered as second record in the RESULT table....)
now where lies the problem.....initially the procedure is very fast.... but it gradually slows down .....because(when it checks the 10th record for duplication it compares the entry in RESULT table for 9 times only *** similarly when it checks the 100th record it compares it for 99 times *** similarly when it checks the 10000th record it compares it for 9999 times so here lies the problem....
when it checks the 100000th record it gets dammm slow... what i have get till now is that i have checked.....>>>>> 5000 records in 4 mins.... 25000 records in 22 mins.... and 100000 records in 20 hours....(means initially its faster but it gradually slows down) ************************************************** ************************ here i m giving the code for the procedure...... ************************************************** *************************

I have 1+ CSV files (using a foreach loop) which I'm doing a lot of transform work on and then inserting into a SQL database table. Each CSV file usually contains about 2 days worth of data (contains date stamps) - somewhere in the region of 60k records per day. The destination table currently contains 3 million+ rows and will get bigger. I need to make sure that before inserting into the destination table, the data doesn't already exist.
I've read the following article: http://www.sqlis.com/311.aspx While the lookup method works, it takes ages and eats up memory as it caches the 3m+ records before running for each CSV. Obviously this will only get worse as the table grows in size.
To make things a little more efficient what I'd like to do, is first derive the dates I'm dealing with in the current file - essentially storing the max(date) and min(date) in variables. Then in the lookup SQL use those vars, to reduce the amount of data that needs to be brought into the transformation to check against before inserting into the destination table. Lookup SQL eg. SELECT * FROM MyTable WHERE Date BETWEEN varMinDate AND varMaxDate.
Ideally I'd use an aggregate transformation and then use the subsequent output from that either in the lookup query or store the output in vars, but I don't think you can do that and I get the feeling I'm approaching this with the wrong mindset.
I have some my below requirment to loading some last year and currnet year records for some ID's in my table,
We have to load the ID's that are active at the end of the year for the prior year and ID's that are active as of today for the current year.Here is the scenario when the ID is currently terminated but active at the end of the prior year and the record is not in the table.so, we didn’t load the count for the prior year
Here prior year is 2015-2015 and Current year is 2015-2016
CREATE TABLE remp_year (ID INT, STATUS NVARCHAR(100) NULL, START_DATE DATE NULL, END_DATE DATE NULL, date_year nvarchar(10) NULL)INSERT INTO remp_year VALUES (10,'Active','2015-05-26','2015-12-31','2015-2016');
[Code] ...
Here ID 20 and 50 for terminated records is the prior year records so it should count for the last year and those are active in this year those will count for this year.
DECLARE @Date SET @Date = 2012 DECLARE @Year int SET @Year = (SELECT DATEPART(yyyy,@Date)) SELECT @Year AS Year --SELECT * -- FROM [Orders].[dbo].[Orders] od -- WHERE .Orderl_Date < @Date; ----WHERE DATEPART(yyyy,@Date)= @Year ----WHERE DATEPART(yyyy,od.Order_Date)= @ArchiveYear
I am looking to pull all records for current & previous calendar year in one query. I know how to pull the current calendar year, but how would I pull current & previous?
hi, i am a nubie, and struggling with the where clause in my stored procedure. here is what i need to do: i have a gridview that displays records of monthly view of data. i want the user to be able to page through any selected month to view its corresponding data. the way i wanted to do this was to set up three link buttons above my gridview: [<<Prev] [Selected Month] [Next>>] the text for 'selected month' would change to correspond to which month of data was currently being displayed in the gridview (and default to the current month when the application first loads). i am having trouble writing the 'where' clause in my stored procedure to retrieve the selected month and year. i am using sql server 2000. i read this article (http://forums.asp.net/thread/1538777.aspx), but was not able to adapt it to what i am doing. i am open to other suggestions of how to do this if you know of a cleaner or more efficient way. thanks!
I am very VERY new to using Visual Studios... I have a SQL database with a table in it "table1" inside the table there is a field "ID" I have made a new website project thing, and I have a textbox and a submit button What I want to do is make a function that will check if what the user has typed into ID is valid, e.g. it exists in the database Can anyone point me in the right direction about how I could do this? Thanks very much
Which is the best way to check the size of a database from Transact SQL ? (Selecting from Sysfiles gives a totally different result compared to right-clicking a database and selecting Properties. It's the result from the latter than I want to obtain through Transact sQL.)
I have written some code that selects all the databases on our server then uses a while loop to execute some dynamic sql to query a table in each database. The problem is some of the databases dont have the correct permissions so the query breaks. Is it possible to check to see if the database has the correct permissions before I execute the dynamic SQL and if it doesn't move onto the next one in the list?
I would like to be able to check if a certain entry exists in a SQL table. Ideally, the output would be a boolean so I can use it in an IF statement which would tell it what to do depending on whether or not the entry exists. Thanks for anyone that helps. :)
Hi all, We have been checking the database by dbcc checkdb,through a automated task on our production server (nightly task run everday)d we always getting the message given below.
Msg 625, Level 20, state 1 Could not retrieve row from logical page 957298 via RID because the entry in the offset table (=0) for that RID (=17) is less than or equal to 0.
If anyone knows about this error message, can you kindly post the message.
I have the following script that calculates Sales by month and current year.
We run a Fiscal year from April 1st thru March 31st.
So April 2012 sales are considered Fiscal Year 2013.
Is there a way I can alter this script to get Fiscal Year Totals?
select ClassificationId, YEAR(inv_dt) as Year, cus_no, isnull(sum(case when month(inv_dt) = 4 then salesamt end),0) as 'Apr', isnull(sum(case when month(inv_dt) = 5 then salesamt end),0) as 'May', isnull(sum(case when month(inv_dt) = 6 then salesamt end),0) as 'Jun', isnull(sum(case when month(inv_dt) = 7 then salesamt end),0) as 'Jul',
[Code] ....
Data returned looks like the following.
ClassificationID Year Cus_no Apr May June .... 100 2012 100 $23 $30 $400 100 2013 100 $40 $45 $600
What I would need is anything greater than or equal to April to show in the next years row.
I have three web form controls, a ddl that contains the day, another ddl that contains the month and a textbox that contains the current year. To send the date chosen by the user to the database, I join the three web form control values so that the resultant string is ‘day/month/year’ thus:
And the resultant string is: dd/mm/yyyy, for example 30/08/2004. But the problem is if the user does not select any day or any day and month, then the resultant string is for example; 00/08/2004 or 00/00/2004, but the problem is the database does not accept this format as datetime. How can I do it?
I want the user has the possibility to chose as well only the month and year, and as well only the year. Is it possible to send to the database the datetime format with only the month and year, or only the year?
I have two queries that give me the total sales amount for the current year, and the last year.
SELECT SUM([Sales (LCY)]) FROM [$Cust_ Ledger Entry] cle LEFT OUTER JOIN dw.dim.FiscalDate fd ON fd.CalendarDate = cle.[Posting Date] WHERE [Customer No_] = '10135' AND fd.CalendarYear = '2013'
[Code] ....
I would like to learn how to be able to make this a single query and end up with two columns and their summed up totals. Like it shows on the attached image.
This is my query without the columns I need:
SELECT c.CustomerNumber ,c.Name ,c.ChainName ,c.PaymentTermsCode ,cle.CreditLimit AS 'CreditLimit' ,SUM(cle.Amount) AS 'Amount'
I have 3 Field on my table. ID (int PK),Name(nvarchar(50),PubDate(DateTime). "PubDate" may have values between "1/1/1996" "1/1/2007" NOw How could I group Table Records base on Year of the Field "PubDate"-1996,1997,...,2007- As I think, First I must Retrieve each Record Year suppose Record1 (ID=1 Name "Something" PubDate=2007) and then List and Group them. But I don't whether this function Is available in MSSQL 2005.
hi i have over 200 tables with all same column and data type locate all over the server(20)different database. so i have table call Tname to stored all the link like (databasename.dbo.tablename) so my job will call the Tname table to use cursor to insert records. but the problem is there's one or more table's column name K datatype has been modify by someone else. so is it cause the job fail. if there a way or SQL statment that i can use Table Tname to see which one is missing column name K? and is there a way i can print out all the datatype and len for all the table column k? please help thanks
When my app starts up I want to ensure that the database compatibility level has been set to 90. I know about sp_dbcmptlevel, but that only seems to work in an interactive session; the documentation says it can't be used in a stored procedure, and that appears to be true. Does anyone know how I could read the database compatibility level in a stored proc?
I'm using PHP with SQLServer2k to create a page containing monthly counts of episodes at a facility occurring between two user selected month/year combinations. For instance, the user could select 10/2003 and 2/2004 and facility X and get a line for each month showing the count of episodes occuring in that month.
The problem is that the episode date is stored in three integer fields (epiday, epimonth, epiyear) and I'm having a terrible time getting them into a format where I can use them in a between statement.
I've tried evaluating the parts of the episode date seperately like:
where (epimonth>=10 and epiyear=2003) or (epimonth<=2 and epiyear=2004)
and that works, but what happens when someone wants to see from 10/2002 to 2/2004?
We have customers who are new to this year (2014) and there same customers in last year (2013). also there are customers we have not received business this year but only last year. so there are 4 conditions.
1) New customer (2014) - Customer(B) 2) Old Regular customer (2013 and 2014) - Customer(A) 3) Last Year (Lost) customer (2013) - Customer(C), no business received in year(2014)
For example we have a transaction table:
TransactionId, ReceivedDate, Customer 1, 2-Dec-2013, A 2, 3-Jan-2014, A 3, 2-Mar-2014, B 4, 25-Nov-2013, C
I want results like
Customer, Business (this year activity/last year activity) A, 1/1 B, 1/0 C, 0/1
How can i show this for each year? I used to separate it month wise as below but it does not return applying year with each customer anyhow...
select t.customerId, YEAR(Receiveddate), sum(case month(ReceivedDate) when 1 then 1 else 0 end )as Jan, sum(case month(ReceivedDate) when 2 then 1 else 0 end )as Feb, sum(case month(ReceivedDate) when 3 then 1 else 0 end )as Mar, sum(case month(ReceivedDate) when 4 then 1 else 0 end )as Apr,
HiI want to write a function that can return a sum for a given daterange. The same function should be able to return the sum for the sameperiod year before.Let me give an example:The Table LedgerTrans consist among other of the follwing fieldsAccountNum (Varchar)TransdateAmountMST (Real)The sample data could be1111, 01-01-2005, 100 USD1111, 18-01-2005, 125 USD1111, 15-03-2005, 50 USD1111,27-06-2005, 500 USD1111,02-01-2006, 250 USD1111,23-02-2006,12 USDIf the current day is 16. march 2006 I would like to have a functionwhich called twice could retrive the values.Previus period (for TransDate >= 01-01-2005 AND TransDate <=16-03-2005) = 275 USDCurrent period (for TransDate >= 01-01-2006 AND TransDate <=16-03-2006) = 262 USDThe function should be called with the AccountNum and current date(GetDate() ?) and f.ex. 0 or 1 for this year / previous year.How can I create a function that dynamically can do this ?I have tried f.ex. calling the function with@ThisYear as GetDate()SET @DateStart = datepart(d,0) + '-' + datepart(m,0) +'-'+datepart(y,@ThisYear)But the value for @dateStart is something like 12-07-1905 so thisdon't work.I Would appreciate any help on this.BR / Jan

What I am trying to do is create a DAX formula to rank each event in the order that it happened for the year. So I want to end up with something like this. This way I can compare the events year over year as the events don't happen on any regular time schedule.
I have tried to do this by creating a formula that will give me the day number of the year:
Day of Year =(YEARFRAC(CONCATENATE("Jan 1 ", YEAR([Event Date])),[Event Date])*360)+1
Then using rankX on this table, but I cant seem to get the proper result. Perhaps I am not understanding the use of rankX or going about this the right way.
=RANKX(FILTER(Event,EARLIER(Event[Event Year])=Event[Event Year]),Event[Day of Year])
or
=RANKX(All(Event[Event Year]),[Day of Year],,1,Dense)
While cleaning up some code, I ran across the following statement in a stored proc - the purpose of which is to determine if a table exists in the local database: SELECT * FROM dbo.sysobjects where id = object_id(N'[dbo].[XML_PRINTDATE]') and OBJECTPROPERTY(id, N'IsUserTable') = 1of course I removed it from the IF just for testing purposes, but my quandry is this... Why chose that select (converting table name to object ID) rather than just doing THIS:SELECT * FROM dbo.sysobjects where name = N'XML_PRINTDATE' and OBJECTPROPERTY(id, N'IsUserTable') = 1
I first thought it was to gain access to the "id" column value (and that may yet be the purpose of it), but the second code seems to work just peachy (I assume because the id column is present in the sysobjects table itself).
A follow-on question is this: When I try to do the same check from another server (i.e.SELECT * FROM APRECEIVE1.DailyProd.dbo.sysobjects where name = N'XML_PRINTDATE' and OBJECTPROPERTY(id, N'IsUserTable') = 1) it of course fails because OBJECTPROPERTY only looks for the id on the local database.
So, do I CARE if it is a user table? (I am reasonably sure it is, of course) and if so, is there a way to check on the remote server for the object type?
Bottom line is I Think I can just simplify things and check for the object name on the remote server, but just don't want to take away any "warm fuzzy feeling" generated by the original stored proc, if such a warm fuzzy is of any benefit (though don't get me started on the relativity of warm fuzzies, I wrote my Thesis on that ;) )
I have a form view that I am using to insert new data into a sql express database and would like to find a way to avoid attempting to insert a record if the key already exists. is there a way to do this with the formview insert command. Everything works great until I try to add a record with an already existing value in the unique key field, then it breaks.
