Transact SQL :: Find Missing Months In A Table For The Earliest And Latest Start Dates Per ID Number?
Aug 27, 2015
I need to find the missing months in a table for the earliest and latest start dates per ID_No. As an example:
create table #InputTable (ID_No int ,OccurMonth datetime)
insert into #InputTable (ID_No,OccurMonth)
select 10, '2007-11-01' Union all
select 10, '2007-12-01' Union all
select 10, '2008-01-01' Union all
select 20, '2009-01-01' Union all
select 20, '2009-02-01' Union all
select 20, '2009-04-01' Union all
select 30, '2010-05-01' Union all
select 30, '2010-08-01' Union all
select 30, '2010-09-01' Union all
select 40, '2008-03-01'
My requirement is to get the latest start date after a gap in a month for each id and if there is no gap for that particular id minimum date for that id should be taken….Given below the scenario
ID StartDate 1 2014-01-01 1 2014-02-01 1 2014-05-01-------After Gap Restarted 1 2014-06-01 1 2014-09-01---------After last gap restarted 1 2014-10-01 1 2014-11-01 2 2014-01-01 2 2014-02-01 2 2014-03-01 2 2014-04-01 2 2014-05-01 2 2014-06-01 2 2014-07-01
For Id 1 the start date after the latest gap is 2014-10-01 and for id=2 there is no gap so i need the minimum date 2014-01-01
My Expected Output id Startdate 1 2014-10-01 2 2014-01-01
I have a table like FK_ID, Value, Date (here FK_ID is foreign key)this table getting updated frequently by daily bases that means one record per one day(For example in January month it has maximum 31 records or minimum 0 records, in February it has maximum 28 or 29 or minimum 0 records, based on calender year)I need to query this table to get missing dates in between particular monthsfor example for one FK_ID has only 25 records in Jan 2008 month and in Feb 2008 it has 10 records , so i need to get those missing 6 dates from JAN month and 18 dates from FEB monthhow can i query this
I have a problem in finding month and year sequence between to date. one date is minimum date for example march 2005 and one maximum date is today's date april 2008. I need output of month between these years like this

May 2005
......
January 2006

Can any one help me to develop a stored procedure to produce this output...
I've SSRS sales report to which I need to pass the dates for previous month's start date and end date which I am able to pass using below code. However, since the sales report has data from the past year(2014) I need to pass the dates for last year as well. The below code gives StartDate1 as 2015-02-01 and EndDate1 as 2015-02-28. I need to get the dates for past year like 2014-02-01 as StartDate2 and 2014-02-28 as EndDate2
SELECT DATEADD(MONTH, DATEDIFF(MONTH, '19000201', GETDATE()), '19000101') AS StartDate1, DATEADD(MONTH, DATEDIFF(MONTH, '19000101', GETDATE()), '18991231') AS EndDate1
It is all contained in one table. I have got the earliest years by using the YEAR() function and grouping by it. The only problem is that I am having a problem joining the table back onto itself with the subselect because of it's an aggregate.
Here is the first join I have....
SELECT DT.ClientID, Year1 FROM ( SELECT ClientID, YEAR(MyDate) as Year1 FROM MyTable ) AS DT GROUP BY ClientID, Year1 ORDER BY ClientID, Year1
I want to use that as my derived table and then join back to it... but it's not working...
I have a challenge and I'm not sure the best route to go. Consider the following dataset.
I have a table of sales. The table has fields for customer number and date of sale. There are 1 - n records for a customer. What I want is a record per customer that has the customer number and the average number of months between purchases. For example, Customer 12345 has made 5 purchases.
i have a db that gets real time min by min datas everyday but sometimes somehow some of those dates did not written into that db and i wanna know which dates are missing? how can i do it?
I have table A(year int, month int, user varchar(20)), and I am trying to write a view that would show number of distinct users in the last 3 months, last 6 months, last 9 months and last 12 months(all from the most recent year/month) in following format:
I work for an organization that repairs serialized devices. Each time a device is repaired it's serial number is recorded in a database table along with the date it was repaired along with other information about the device. There are multiple cases where a unit has been repaired more than once.
I am trying to write a query that will return the serial only once and that record will be the record of the latest repair date. To sum it up,
Return a list of serials where if a serial exists more than once in the table, return only the instance of the serial record(s) with the max(created_dt). The end result will be a list of distinct serial numbers.
Here is my Query. The problem I believe is in my sub-query but I am not sure how to structure it.
I have a date dimension set in the SSAS Cube. I have been trying get quarter,year,month,semester start and end dates using ClosingPeriod() and OpeningPeriod() functions but not getting the exact value. How the get correct dates for a given date.
Hello,I need to write a query to find out a set of missing number in a givensequence.Eg : a Column in some table has the following dataCol11234568910Here I need to write a query to find out that number 7 is missing in thegiven sequence.One possible solution is by using any loop. But I am looking out if the samecan be achieved using any query.Thanks in advance.Regards,Mahesh
I have a transaction number in my mapping table. I have a matching transaction number in my PDHist table. Sometimes I have matching transaction numbers in my PD table, but not always. This is causing no records to be returned. I have a One to Many relationship between my mapping table and both PD and PDHist.
Also, I need to check for nulls in my foreign exchange table.I can’t post the SQL because this is a classified project. However, it should be something like this, I think.
I have to find the latest file in a folder and export data to a table in sql server. The code should be something that has to be incorporated into a t-sql stored procedure.
The file name would for example abc_defYYYYMMDD.xls. would i be able to find the latest file in the folder using the the datestamp (YYYYMMDD) in the filename.
Please note i would have files in other format and names with datestamp attached to it, so the code has to pick specific file for which the file name starts with 'abc_def'
Finding the earliest datetime entry, and then updating the database on these reults.
I need to query a table of data that has multiple datetime entries in it relating to individual customer records. So one customer could have 1 entry, or it could have 10 entries. I need to be able to identify the earliest of these records, and then on this earliest record update a field value. Example:
My Fields in the table are as follows. Log_ID, Cust_Ref_No, ActionDateTime, Action_Code
The Log_ID is the primary key, and I need to update the Action_Code field on only the earliest entry against a customer record i.e.
I want to create a table that has a datetime column, data type=datetime and I want the date to start form 01/01/2004 00:00:00 to 01/01/2008 00:00:00 the increment will be by minute like
01/01/2004 00:01:00
01/01/2004 00:02:00
01/01/2004 00:03:00 and so on up to 01/01/2008 00:00:00
I will use this time dimension in bussiness objects.
Has anyone written or come across a routine that validates start and enddate in a slow changing dimension? (eg verifies there is no overlap in any of the records).

I have a database of 900+ tables with around 3000 SPs, and views. Manually I reviewed few tables and found that tables are not referenced with FK and I applied few. There are lots of tables and SPs using them in join statement, Is there any way with which I can get each tables missing references, any DMV or other manual script which tells about this?
I have one table with many records in the table. Each time a record is entered the date the record was entered is also saved in the table. I need a query that will find all the missing records in the table. So if I have in my table:
ID Date Location 1 4/1/2015 bld1 2 4/2/2015 bld1 3 4/4/2015 bld1
I want to run a query like
Select Date, Location FROM [table] WHERE (Date Between '4/1/2015' and '4/4/2015') and (Location = bld1) WHERE Date not in (Select Date, Location FROM [table])
I'm trying to write some code that will get me the last day of each month for the months that fall between 2 dates.
So if i have a table with a record with a begin date of 01-01-2012 and an end date of 09-14-2012, i would want a result set of the following 9 records:
So i basically get the last day of each month between the dates listed, including the months that the dates are in themselves (inclusive list).
I have a date dimension table with 1 row for every day from 1990 to 2025. There is also a field with the Last day of Month for a given date. My issue is that I'm not sure how to write the T-SQL to get what I need.
I have created a Table Called Log in SQL Server 7. I use this table as you can guess to log all transaction performed in my program. However, I would like my program to run an SQL Statement that will flush all entries in the table Log that are 6 months old from today's date.
I am unable to find the statement that will execute this operation.
