Transact SQL :: Updating Table Rows With Overlapping Dates (extend)
Dec 2, 2015
This question is extension from the topic Updating table Rows with overlapping dates: [URL] .....
I am actually having a table as following:
Table Name: PromotionList
Note that the NULL in endDate means no end date or infinite end date.
ID PromotionID StartDate EndDate Flag
1 1 2015-04-05 2015-05-28 0
2 1 2015-04-23 NULL 0
3 2 2015-03-03 2015-05-04 0
4 1 2015-04-23 2015-05-29 0
5 1 2015-01-01 2015-02-02 0
And I would like to produce the following outcome to the same table (using update statement): As what you all observe, it merge all overlapping dates based on same promotion ID by taking the minimum start date and maximum end date. Only the first row of overlapping date is updated to the desired value and the flag value change to 1. For other overlapping value, it will be set to NULL and the flag becomes 2.
Flag = 1, success merge row. Flag = 2, fail row
ID PromotionID StartDate EndDate Flag
1 1 2015-04-05 NULL 1
2 1 NULL NULL 2
3 2 2015-03-03 2015-05-04 1
4 1 NULL NULL 2
5 1 2015-01-01 2015-02-02 1
The second part that I would like to acheive is based on the first table as well. However, this time I would like to merge the date which results in the minimum start date and End Date of the last overlapping rows. Since the End date of the last overlapping rows of promotion ID 1 is row with ID 4 with End Date 2015-05-29, the table will result as follow after update.
ID PromotionID StartDate EndDate Flag
1 1 2015-04-05 2015-05-29 1
2 1 NULL NULL 2
3 2 2015-03-03 2015-05-04 1
4 1 NULL NULL 2
5 1 2015-01-01 2015-02-02 1
Note that above is just sample Data. Actual data might contain thousands of records and hopefully it can be done in single update statement.
Extending from the above question, now two extra columns has been added to the table, which is ShouldDelete and PromotionCategoryID respectively.
Original table:
ID PromotionID StartDate EndDate Flag ShouldDelete PromotionCategoryID
1 1 2015-04-05 2015-05-28 0 Y 1
2 1 2015-04-23 2015-05-29 0 NULL NULL
3 2 2015-03-03 2015-05-04 0 N NULL
4 1 2015-04-23 NULL 0 Y 1
5 1 2015-01-01 2015-02-02 0 NULL NULL
Should Delete can take Y, N and NULL
PromotionCategoryID can take any integer and NULL
Now it should be partition according with promotionid, shoulddelete and promotioncategoryID (these 3 should be same).
By taking the min date and max date of the same group, the following table should be achieve after the table is updated.
Final outcome:
ID PromotionID StartDate EndDate Flag ShouldDelete PromotionCategoryID
1 1 2015-04-05 NULL 1 Y 1
2 1 2015-04-23 2015-05-29 1 NULL NULL
3 2 2015-03-03 2015-05-04 1 N NULL
4 1 NULL NULL 2 Y 1
5 1 2015-01-01 2015-02-02 1 NULL NULL

I am trying to create a check constraint that prevents entry of a date range that overlaps any other date range in the table. The below example script results in the error message: The INSERT statement conflicted with the CHECK constraint "ck_dt_overlap". what I am doing wrong?
CREATE TABLE t1 (d1 date,d2 date)
go
create function dbo.dt_overlap (@d1 date, @d2 date) RETURNS BIT
AS
BEGIN
IF EXISTS (SELECT 1 from t1 where d1 between @d1 and @d2 or d2 between @d1 and @d2)
RETURN 1
RETURN 0
END
go
alter table t1 add constraint ck_dt_overlap CHECK (dbo.dt_overlap(d1,d2)=0)
go
insert into t1 values ('2015-01-01','2015-02-01')
insert into t1 values ('2015-01-15','2015-02-15')
--BOTH inserts result in the following message: The INSERT statement conflicted with the CHECK constraint "ck_dt_overlap".
drop table t1
drop function dbo.dt_overlap

I have a table with multiple rows per staff person. Each of these rows has staff_id, start_date, and end_date. Per staff, if any start_date comes between the start_date and end_date of a different row, or if any end_date comes between the start_date and end_date of a different row, then I have to flag these records as being identical.
How can I do this? I have tried doing a Cross Apply because I thought that would do Cartesian product (comparing every row), and I've also tried temp tables. But I haven't gotten either of these to work. Here is some dummy data:
if exists (select * from tempdb.dbo.sysobjects o where o.xtype in ('U') and o.id = object_id(N'tempdb..#staff_records')
) DROP TABLE #staff_records;
create table #staff_records
(
staff_id varchar(max),

How can I check the overlapping in a simple table like:
Create table forum (cid int, bfrom date, tfrom date, fval int)
Insert into forum values (1, '2014-01-01', '2014-01-31',10),(2, '2014-01-01', '2014-01-31',12),(1, '2014-02-01', '2014-02-28',8),(2, '2014-02-01', '2014-02-28',6),(1, '2014-03-01', '2014-03-31',11),(2, '2014-03-01', '2014-03-31',5),(1, '2014-04-01',
'2014-04-30',14), (2, '2014-03-01', '2014-04-30',12)
In the example above there is an overlapping for the cid 2 in March. How can I check, which select should I apply?

So What I am trying to accomplish is sum up overlapping time ranges while also keeping Unique data rows within the table. So If a data row is unique meaning it is NOT within a overlapping group of data rows then I want to just insert it into a "final table", but if the data rows are overlapping then I want to grab the min(timestart) and the max(timestop) and the PKID of the data row with the max(timestop) within the overlapping group.
I accomplish this task using nested cursors, however When I place my method into a trigger which runs on INSERT, then my trigger never runs and nothing happens. Is there a way to accomplish this without using cursors. I have placed my cursor method into the sql fiddle to be inspected.
create table temp1
( pkid int,
line int,
dateentry date,
timestart time,
timestop time
)
[Code] ....
DESIRED RESULTS:
1060
1
2015-10-01
16:30:00
17:00:00

how can I check the overlapping and the LostPeriod by chargeid?
create table #forum (contractid int, chargeid int, ByFrom date, ByTo date)
insert into #forum values ('7','18','2005-04-01','2007-03-31'), ('7','19','2008-06-01','2010-03-31'),
('7','20','2014-04-01','2015-06-01'),
('8','10','2003-10-01','2005-03-31'),('8','11','2006-12-01','2007-07-31'),
('9','11','2003-10-01','2005-03-31'),('9','12','2004-10-01','2015-03-31')
As lost period I mean that period that is not covered by any chargeid. By overlapping I mean having two or more charge id in the same period.

I am trying to update a large table which consists of 45 million records , it is taking more than 2 days to the update , below is my approach
1. The table has only one clustered index and no other indexes on the table.
2. I am updating in batches say 20000 record-wise.
3. Changed the recovery mode to bulk logged and auto-growth size is set to 300MB and there is enough space in my disk for transaction log .
But still the query is running slowly.

Given the data below, I have a couple needs:
1) Query to determine if any date ranges overlap (regardless of category, e.g., row ids 6 & 7 below)
2) Query to determine if any date ranges of the same category overlap
declare @t1 table (id int primary key, category int, start_date datetime, end_date datetime)
insert @t1 select 1, 1, '1/1/2015 12:00:00 AM', '1/15/2015 12:59:59 PM'
insert @t1 select 2, 1, '1/16/2015 12:00:00 AM', '1/31/2015 12:59:59 PM'
insert @t1 select 3, 1, '2/1/2015 12:00:00 AM', '2/15/2015 12:59:59 PM'
insert @t1 select 4, 1, '2/16/2015 12:00:00 AM', '2/28/2015 12:59:59 PM'

Hi,
I have a table called "tblProducts" with following fields:-
ProductID(Pk, AutoIncrement), ProductCode(FK), ProdDescr.
So to the above table I have added a new field/column named "ProdLongDescr(varchar, Null)"
So, I need to populate this newly added column with specific values for each row depending on "ProductCode" which is different forevery row. The problem is that I have 25 rows.So instead of Writing 25 individual update scripts, is there a way in which single query will do the same job instead of writing one update query for each row ?. If so can some one guide me how to achieve that OR point to me a good resource.
Below are a couple of Individual update scripts I Wrote. "ProductCode" is different for all 25 rows.
Update tblValAdPackageElement SET ProdLongDescr = 'Slideshows' WHERE ProductCode = 'SLID'
And szElementDescr='Slideshow'
if @@error <> 0
begin
goto ErrPos
end
Update tblValAdPackageElement SET ProdLongDescr = 'CategorySlideshows' WHERE ProductCode = 'SLDC'
And szElementDescr='CategorySlideshow'
if @@error <> 0
begin
goto ErrPos
end
Thanks,

I'm looking for some performance assistance on updating a column value in a table that contains approximately 50 million rows. I have a permanent table in another database that has the key column and value to be set. My query is listed below, but I'm afraid it will run quite awhile. Any suggestions would be appreciated.
update mytable
set column2 = b.column2
from mytable as a
join mytable1 as b
on a.column1 = b.column1
There is a one to one relationship between the two tables.

I'm trying to add random dates to date column in existing table, but these need to be week days (Mon-Fri).I'm a beginner in TSQL, worked with MS Access many years - in Access I used to do something a bit different:
DateAdd("d",(Int((5*Rnd([ID]))+1)),#31/08/2015#)
Table had ID, I gave a date it would start from (31/08/2015) and then range of ID to apply new date:
UPDATE table1 SET table1 .date = DateAdd("d",(Int((5*Rnd([ID]))+1)),#31/08/2015#)
WHERE (((table1 .ID) Between 1 And 5456));
This was applying random dates in range of 31/08/2015 + 5 days, so I could give a starting date of Sunday to get random dates populated over given IDs from Monday to Friday.Now, how can I do it in TSQL?I have a table with ID and dates column. I would like to apply new random dates from some range, but making sure they will be week days.

Hello All
I am trying to figure out if what i am attempting to do is possible and whether or not my approach is wrong to begin with.
I am trying to build a custom report for our accounting system which is Traverse from Open systems. This is what i have done in the stored procedure thus far
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_NULLS ON
GO
ALTER PROCEDURE rptArFLSalesByCustItemized_sp
@custId pCustID,
@dateFrom datetime,
@dateThru datetime,
@itemIdFrom pItemId,
@itemIdThru pItemId
as
set nocount on
-- define some variables for previous year
declare @LYqty int, @LyAmt money, @LYfrom datetime, @LYthru datetime
-- set defaults
SET @itemIdFrom=ISNULL(@itemIdFrom,(SELECT MIN(itemId) FROM tblInItem))
SET @itemIdThru=ISNULL(@itemIdThru,(SELECT MAX(itemId) FROM tblInItem))
SET @LYfrom=DATEADD(YEAR,-1,@dateFrom)
SET @LYthru=DATEADD(YEAR, -1, @dateThru)
-- create small temp table to hold customer info
Create Table #tmpArCustInfo
(
custId pCustID,
custName VARCHAR (30),
)
-- populate customer temp table with info
Insert into #tmpArCustInfo
select custId, custName
from tblArCust
WHERE custId = @custId
-- create a temp table to hold the Data for each Item
Create Table #tmpArSalesItemized
(
itemId pItemId,
productLine VARCHAR (12),
pLineDesc VARCHAR (35),
descr VARCHAR (35),
LYQtySold int,
LYTDQtySold int,
QtySold int,
LYTDsales money,
totalSales money,
LastInvDate datetime,
)
-- populate the temp table with all of the inventory items
insert into #tmpArSalesItemized
select ii.itemId, ii.productLine, ip.Descr, ii.Descr, 0,0,0,0,0, NULL
from tblInItem ii, tblInProductLine ip
where ip.productLine = ii.productLine
AND ii.itemId BETWEEN @itemIdFrom AND @itemIdThru
-- update table with this years quantities
update #tmpArSalesItemized
SET QtySold = (select SUM(QtyOrdSell) from tblArHistDetail hd
where TransId IN (select TransId from tblArHistHeader where custId = @custId)
AND orderDate IN (select OrderDate from tblArHistHeader where OrderDate BETWEEN @dateFrom AND @dateThru)
AND hd.partId BETWEEN @itemIdFrom AND @itemIdThru
GROUP BY hd.partId
)
-- Return the temp tables results
select * from #tmpArSalesItemized, #tmpArCustInfo
drop table #tmpArSalesItemized, #tmpArCustInfo
return
GO
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO
My problems begin where i want to start updating all of the Qty's of the QtySold field. I have managed to get it to write the same sum in every field but i cannot figure out how to update each row based on the sum of the qty found for that item in the tblArHistDetails table, trouble is too that there is no reference to the custId in that table either. The custId resides in tblArHistHeader and is linked to the details table via the TransId column. So really i need to update many rows based on criteria from 2 other tables.
Can anyone please help? I dont have a clue how to make this work, and most of what i have learned about sql thus far has been from opening other stored procs etc in the accounting system and just reading to see how the developers have done things.
Thanks
Jamie

d. Update Row read in a (above) with GradeEndDate = '6/30/2007 12:00:00 A.M.' and GradeCurrentFlag = 'False'
2. tPersonBasePayHist Table Script Two (Needs to be run second)
a. Read tPersonBasePayHist Table and Select rows with PersonBasePayEndDate = NULL
b. Calculate New PersonBasePayAmount = PersonBasePayAmount * Incr% (Round To Nearest Whole Dollar)
c. Create New Row for this table using information from row read above and insert new information where indicated :
PersonGUID - Same
PersonBasePayStartDate - '7/1/2007 12:00:00 A.M.'

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'
For the above table, the answer should be:
ID_No OccurMonth
----- ----------
20 2009-02-01
30 2010-06-01
30 2010-07-01
1) don't include an ID column,
2) don't use the start date/end dates in the data or
3) use cursors, which are forbidden in my environment.

Hi,
I have an application where I'm filling a dataset with values from a table. This table has no primary key. Then I iterate through each row of the dataset and I compute the value of one of the columns and then update that value in the dataset row. The problem I'm having is that when the database gets updated by the SqlDataAdapter.Update() method, the same value shows up under that column for all rows. I think my Update Command is not correct since I'm not specifying a where clause and hence it is using just the value lastly computed in the dataset to update the entire database. But I do not know how to specify a where clause for an update statement when I'm actually updating every row in the dataset. Basically I do not have an update parameter since all rows are meant to be updated. Any suggestions?
SqlCommand snUpdate = conn.CreateCommand();
snUpdate.CommandType = CommandType.Text;
snUpdate.CommandText = "Update TestTable set shipdate = @shipdate";
snUpdate.Parameters.Add("@shipdate", SqlDbType.Char, 10, "shipdate");
string jdate ="";
for (int i = 0; i < ds.Tables[0].Rows.Count - 1; i++)
{
jdate = ds.Tables[0].Rows[i]["shipdate"].ToString();
ds.Tables[0].Rows[i]["shipdate"] = convertToNormalDate(jdate);
}
da.Update(ds, "Table1");
conn.Close();
-Thanks

SQL 2014 I've inherited a db that has several partitioned tables. They are partitioned by month. We're approaching the last partition, 11-30-2015, so we need to extend the tables. My question is how do I do this? There are Partition Schemes and Partition Functions setup at the db level. I've figured out how to ALTER those. Next I go to a table that I know is partitioned, right-click Storage and select Manage Partitions.
My only option is to "create a staging table for partition switching". Not knowing what switching is, I'm not sure if this is what I want to do. All I want to do is add new partitions to the table - and remove some of the old ones since they are empty due to archiving of data.
So, what is the proper steps to adding new partitions to a table that is already partitioned?

Hi all,
Does anyone know how to setup the "table details" to take up all the space in a page (extend the boarder to the end of the page) even there is only one record in the table details?
Normally, for example, if you got a table in a report, if the table has only one record, the boarder of table will only take up maybe 1/4 of the page space (header, 1 line details, footer). if the table has 5 records, it may take up half of the page, but the boarder of table neven extend to the end of the report and i wwant it happen!!!!!!! Thank you.
Cheers,
Bryan

I have a question regarding the total count of the table rows
Select count (name) from test. Lets say I have got 200 count. And Select count (lastname) from test1.I have got 200.And this counts I should store it in "There are nn name items awaiting your attention and nn pending lastname's awaiting your approval".
So now I have to store the count in 'nn'.

I have a table for example like following
DECLARE @tmpTable table
(
name varchar(10),
address1 varchar(10),
phnno varchar(10),
mobno varchar(10)
)
INSERT INTO @tmpTable(name,address1,phnno,mobno)
[Code] ....
I want to remove all empty rows like row 1,2 and 3 in the above example.
I can't check all columns null values as there are many columns in my actual table.

I am using Sql Server 2008 R2.I have a existing query that basically says
Select Top 50 Subscriber_ID, Member_Name, Group_ID
from my_table
order by rand(checksum(newid()))
However the client now wants to have at least two from each group_id. There are 17 different groups. When I run this as is I get about six of the 17 groups in the results. How can I change this to get at least two results from each group_id?

I have a table with more than 1000 records. The columns look like this
Import id | Reference | Date | Username | Filename
Some of the rows are duplicates except for the fact that they have different values for the first column alone (import id)
11111 test 21-07-2015 xxxxxx yyyyyy
22222 test 21-07-2015 xxxxxx yyyyyy
Is it possible to delete these kind of duplicate rows by ignoring the import id ?

Copy out all data from a DB table into/across delimited text file(s) ensuring that each text file size is no more than 3MB.Have created a SSIS solution where it achieves this requirement ..well sort of achieves the requirement ... Here it what the current solution (sparing the minute details) does in a nutshell & Problems with it:
1) Created a function (Script below) which finds the
maximum row size in bytes in a given DB table & uses it to calculate
how many rows can be copied out into a text file without exceeding 3MB size limit.
For instance: A DB table selected had 788 rows in total and this function for this particular table returned a value of 181 rows { select [dbo].[udf_GetRowPartitionNumber](‘<TableName>’)as #ofRowstoPartitionTableby --181} meaning in order to not exceed the requirement of 3MB per text file, we had to copy all the data from DB table across (create) 5 text files {Select
CEILING(788
[code]....
