T-SQL (SS2K8) :: Update DateTime Field With Date-inserted From Previous Record?
Jan 14, 2015
My goal is to update the "PriorInsert" field with the "DateInserted" from the previously inserted record where the WorkOrder, MachineNo, and Operator are all in the same group.
While trying to get to the correct previous record, I wrote the query below.
P.S. The attached .txt file includes a create and insert tbl_tmp sampling.
select top 1
a.ID,
a.WorkOrder,
a.MachineNo,
a.Operator,
a.PriorInsert,
[code]...

We are getting data feed from Oracle database in our project. Everyday we will need to track if any rows got inserted/updated/deleted in the source and get that update right into our data warehouse.
Currently we are taking a dump of the required table (as it is) to our staging DB and comparing it with previous day data to track the changes (column by column comparison). This approach is working currently but has performance bottleneck. There is no tracking column (eg. last modified date or time) in source that will give us any idea of what got changed. Also there is no identity key or primary key in the source data.
Is there a way in SQL Server to get that inserted/updated records only instead of comparing column by column to track the changes?

Was wondering if there is easy anyway to autopopulate a field by pulling a value from a field in the previous record?
For example, I have a table with fields name "Dist_From" and "Dist_To". When I add a new record I would like it to populate the "Dist_From" field with the "Dist_to" value from the previous record.
TIA

Let's say the first row returned has StartDate = 1/1/2014 and EndDate is 1/2/2014. The next row I want the StartDate to equal the previous row EndDate so it would be 1/2/2014 as StartDate. This compounds every row basically the third row StartDate would be the second row EndDate. All in one select statement if it can be done. Using SQL2008r2.

I want to find previous date from selected date. below is the sample data.
DECLARE @StartDate SMALLDATETIME = '1/11/2016'
declare @tempdat table(repdate smalldatetime)
insert into @tempdat values ('10/26/2015')
insert into @tempdat values ('10/29/2015')
insert into @tempdat values ('11/1/2015')
insert into @tempdat values ('11/27/2015')
insert into @tempdat values ('11/25/2015')
insert into @tempdat values ('11/20/2015')
insert into @tempdat values ('11/10/2015')
insert into @tempdat values ('11/10/2015')
insert into @tempdat values ('11/11/2015')
insert into @tempdat values ('11/11/2015')
Now if i pass the date '10/26/2015' then i want select prev date of passed date. in this example no prev date is available, so result set would be nothing.
if i pass the date '11/10/2015' then result should be '11/1/2015' which is prev small date available in table.

I am working in sqlserver 2008 R2 and below is my sample research query. I am trying to get previous 6 months data.
WITH CutomMonths
AS (
SELECT UPPER(convert(VARCHAR(3), datename(month, DATEADD(MM, DATEDIFF(MM, 0, GETDATE()) - N, 0)))) Month
,DATEADD(MM, DATEDIFF(MM, 0, GETDATE()) - N, 0) startdate
,DATEADD(MM, DATEDIFF(MM, 0, GETDATE()) - N + 1, 0) enddate
FROM (
VALUES (1)
[Code] ...
Current output what i am getting:
Expected Output:
I found why the April month i didn't get the $20 because the startdate of my perks CTE '2014-04-03'. If it is '2014-04-01' then i will get the expected output.
But i should not change the the date on perks. How to neglect this date issue and consider the month instead to get the expected 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

I embedded a SQL query in excel that gets some datetime fields like "TASK_FINISH_DATE" .
How can I convert a datetime field to a date field in SQL in a way that excel will recognize it as a date type and not a text type?
I tried:
CONVERT(varchar(8),TASK_FINISH_DATE ,3)
CONVERT(Date,TASK_FINISH_DATE ,3)
CAST(TASK_FINISH_DATE as date)
**all of the above returned text objectes in excel and not date objects.

I am trying to drag data from Informix to Sql Server. When I kick off the package
using an OLE DB Source and a SQL Server Destination, I get DT_DBDATE to DT_DBTIMESTAMP
errors on two fields from Informix which are date data ....no timestamp part
I tried a couple of things:
Created a view of the Informix table where I cast the date fields as datetime year to fraction(5), which failed.
Altered the view to convert the date fields to char(10) with the hopes that SQL Server would implicitly cast them
as datetime but it failed.
What options do I have that will work?

I have a datetime field that is just the date and zero for the time element. I also have a varchar field that is of the format 09:25:30
is there an easy way to add these together?
I don't mind if they get converted to integer as it will be used for comparison.

I have a table with a datetime field (named "lnDateDone") and an integer field (named "PlannedHour"). I want to build a new datetime field with the same value as lnDateDone and replacing the hour part by the PlannedHour field. Example:
lnDateDone = '2014-04-09 13:22:31.544'
HourPlanned = 14
new datetime field = '2014-04-09 14:00:00'
I tried the following:
CAST(SUBSTRING(CAST(lnDateDone AS VARCHAR(25)),1,12) + CAST(PlannedHour AS VARCHAR(2)) + SUBSTRING(CAST(lnDateDone AS VARCHAR(25)), 15, LEN(lnDateHeureFin)) AS SMALLDATETIME) AS DatePrevue
but it won't work when casted in DateTime format, only in varchar, but I want it in datetime as I need to do compute some values using date manipulation functions.
How can I do that?

Here is a CTE query
With mstrTable(ItemNo, Sales)
as (
Query1
Union All
Query2
)
Select Row_Number () Over(Partition by ItemNo order by ItemNo)as RowNo, ItemNo, Sales
From mstrTable
order by ItemNo
The results from Query1 and Query2 overlap sometimes.
The result set looks like:
1 Item1 10000
2 Item1 10000
1 Item2 20000
1 Item3 30000
I only want the first occurrence of each item. The desired result set is:
1 Item1 10000
1 Item2 20000
1 Item3 30000
I am not able to add a "Where RowNo = 1" to the query. SQL returns an "invalid field name".How would I obtain a record set that returns just the first occurrence of the ItemNo field?

I have a table with Million plus records. I have been able to calculate the Trial_Balance for all months.
Now I am trying to provide a Beginning Balance for all months and the Logic is the Beginning Balance of July would be the Trial_Balance of June. I thought I could just do a self Join but this is not working.
UPDATE dbo.TrialBalance
SET Beginning_Balance_Debit = B.Trial_Balance_Debit
FROM (SELECT DATEADD(month, -1, Calendar_Month) AS PrevCalMonth,Trial_Balance_Debit
FROM dbo.TrialBalance) AS B INNER JOIN dbo.TrialBalance A

I have a standard datetime and I need to convert it to the client specification of:
YYYY-MM-DDThh:mm:ssTZD
eg: 2009-04-16T19:20:30+08:00
I am not sure of the easiest way to do this.
The test code below gets me part of the way but I am unsure on how to get the offset on the end without hardcoding to much.
DECLARE @datetime DATETIME = '2014-12-20 12:30:00'
SELECT CONVERT(VARCHAR(30),@datetime,127)

We have 2 columns:
StartDate - data type Date
StartTime - data type Time
I need to combine them into a DateTime data type. For now, I convert each of them into varchar, insert space in between, and convert to DateTime, like this:
convert(datetime, convert(varchar(10), EndDate , 101) + ' ' + CONVERT(varchar(20), EndTime,24))
Is there a better, more elegant way to do this?

Hi
What is the best practice to get the date from a smalldatetime field without the time.
The table contains 5 minute readings for energy consumption in the column period.
Now i need to get all the readings form some dates.
SELECT dbo.TBL_Data.*
FROM dbo.TBL_Data
WHERE (Period IN (CONVERT(DATETIME, '2003-12-31', 102), CONVERT(DATETIME, '2004-01-01', 102)))
this result contains only the readings for the timestamp 00:00
so how to select the whole day ?
kind regards

Hi,
I have used smalldatetime datatype to store my date and time values. i want to store just the date or time but the problem is it stores both the date and time. For eg, if i add the the date 03/11/2004, it also the stores the current time automatically. so the new value will be something like 03/11/2004 10:00:00 AM where i want just 03/11/2004. further problem is even though i managed to store just the date like 03/11/2004 in the database, whole date and time shows up when i display it in my pages.
any help will be appreciated.
thanx,

OK, I know this is really simple but I can't get my statement to pull just the date from a datetime field!
Here's my query:
select *
from tblPR
where date between convert(datetime, dateadd(day,-day(getdate())+1,getdate()),103)
and convert(datetime, dateadd(day,-day(getdate()),dateadd(month,1,getdate())),103)
I get no errors but I get the timestamp too and I only want the date.
Where am I going wrong?!
Thanks in advance,
Brett

Large design flaw, I know, but we have a table with a varchar field which contains alpha - numeric values. I need to change just the numerics, which can be in an position on the field:
Sample data of the field:
Rec1: Sally Morgan 201-555-1212
Rec2: 555-4040 John Smith
Rec3: Jane Houstin 201-555-6452 ext1223
Desired result:
Rec1: Sally Morgan 999-999-9999
Rec2: 999-9999 John Smith
Rec3: Jane Houstin 999-999-9999 ext9999
There's a bunch of UDFs out there for selecting just the numerics, but I'm having trouble throwing it into a viable script for repeatable execution.

3 1 y
4 1 y
Table B - data example
Idno Entity
1 1
2 1
3 1
Table C - data example
Idno Entity
4 1
I want to update the value flag in table A.Update flag from n to y if idno A in table B and and idno A not in table C, so from table A above, first record and 3rd record remain unchange but 2nd record, flag will be changed from n to y. 4th record where idno A not in table b and in Table C so flag will change from y to n. is it possible, or do i need to use the "fetch" method to compare record by record.
