So let's say I have a table Orders with columns: Order# and ReceiptDate. Order#'s may be duplicated (Could have same Order# with different ReceiptDate). I want to select Order#'s that go back 6 months from the last ReceiptDate for each Order#.
I can't just do something like:
SELECT *
FROM Orders
WHERE ReceiptDate >= add_months(date,-6)
because there could be Order#'s whose last ReceiptDate was earlier than 6 months ago. I want to capture all of the instances of each Order# going back 6 months from each last ReceiptDate relative to each Order#.

Ok, I have two parameters - @StartDate and @EndDate. We only care about the date part of these paramters. What I would like to do is create a table with one record for each date between these two values. For example:
@StartDate = '01/01/2008'
@EndDate = '01/8/2008'
Should yield a table with 9 records in it for every day between @StartDate and @EndDate like so:
01/01/2008 <datacol1> <datacol2>
01/02/2008 <datacol1> <datacol2>
01/03/2008 <datacol1> <datacol2>
01/04/2008 <datacol1> <datacol2>
01/05/2008 <datacol1> <datacol2>
01/06/2008 <datacol1> <datacol2>
01/07/2008 <datacol1> <datacol2>
01/08/2008 <datacol1> <datacol2>
I know I could just do a WHILE (@StartDate <= @EndDate) loop and insert records into a temp table but I'm looking to see if there are any new methods/techniques to achieve this with a more simple statement.

I have a requirement where i want to delete the records based on the Date column. I have table which contain the columns like machinename ,lasthardwarescandate
I want to delete the records based on the max(Lasthardwarescandate) i.e. latest one, column where the machine name is duplicate menace it repeats. So how would i remove the duplicate machine names based on the Lasthardwarescandate column(There are multiple entries for the Lasthardwarescandate so i want to fetch the latest date column).
Note: Duplication should be removed based on “Last Hardware Scan” date.
Only latest date should be considered from multiple records for the same system. "

I have a scenario to fetch records for each ID on 2 conditions. There are 2 types of Product type for each ID. PFE and PRI. I need only latest active PFE and at the same time all the latest PRI should be closed. (meaning, only PFE should be in Active status currently)
1.) Latest Product type PFE should be A (active) status for the particular ID
2.) At the same time ALL the latest PRI should be C(closed) status for the same ID
I have give example with 3 scenarios and desired output
1.) For ID 101, Latest PFE is active and all latest PRI is closed ----> Should come in result
2.) For ID 102, Latest PFE is Closed and all latest PRI is closed ---->Should NOT come in result

I would like to have records in my Absences table split up into multiple records in my query based on a start and end date.
A random record in my Absences table shows (as an example):
resource: 1
startdate: 2014-08-20 09:00:00.000
enddate: 2014-08-23 13:00:00.000
hours: 28 (= 8 + 8 + 8 + 4)
I would like to have 4 lines in my query:
resource date hours
1 2014-08-20 8
1 2014-08-21 8
1 2014-08-22 8
1 2014-08-23 4
Generating the 4 lines is not the issue; I call 3 functions to do that together with cross apply.One function to get all dates between the start and end date (dbo.AllDays returning a table with only a datevalue column); one function to have these dates evaluated against a work schedule (dbo.HRCapacityHours) and one function to get the absence records (dbo.HRAbsenceHours) What I can't get fixed is having the correct hours per line.
What I now get is:
resource date hours
...
1 2014-08-19 NULL
1 2014-08-20 28
1 2014-08-21 28
1 2014-08-22 28
1 2014-08-23 28
1 2014-08-24 NULL
...
... instead of the correct hours per date (8, 8, 8, 4).
A very simplified extract of my code is:
DECLARE @startdate DATETIME
DECLARE @enddate DATETIME
SET @startdate = '2014-01-01'
SET @enddate = '2014-08-31'
SELECTh.res_id AS Resource,
t.datevalue,
(SELECT ROUND([dbo].[HRCapacityHours] (h.res_id, t.datevalue, t.datevalue), 2)) AS Capacity,
(SELECT [dbo].[HRAbsenceHours] (9538, h.res_id, t.datevalue, t.datevalue + 1) AS AbsenceHours
FROMResources h (NOLOCK)
CROSS APPLY (SELECT * FROM [dbo].[AllDays] (@startdate, @enddate)) t
p.s.The 9538 value in the HRAbsenceHours function refers to the absences-workflowID.I can't get this solved.

I have a situation where deleting old records is blocking updating latest records on highly transactional table and getting timeout errors from application.
In details, I have one table called Tran_table1 in OLTP database. This Tran_table1 is highly transactional table, it will receive data for insert/update continuously
While archiving 2 years old records from Tran_table1 into Tran_table1_archive in batches(using DELETE OUTPUT INTO clause), if there is any UPDATEs on Tran_table1,these updates are getting blocked and result is timeout errors in application.
Is there any SQL Server hints to avoid blocking ..

Is it possible to delete multiple rows from multiple tables based on information specified. Can you write a query that would pull the information if you knew what tables it would need to look in? If anyone know I would greatly appreciate any help I am not sure of this.

I'm looking for a way of taking a query which returns a set of date time fields (probable maximum of 20 rows) and looping through each value to see if it exists in a separate table.
E.g.
Query 1
Select ID, Person, ProposedEvent, DayField, TimeField
from MyOptions
where person = 'me'
Table
Select Person, ExistingEvent, DayField, TimeField
from MyTimetable
where person ='me'
Loop through Query 1 and if it finds ANY matching Dayfield AND Timefield in Query/Table 2, return the ProposedEvent (just as a message, the loop could stop there), if no match a message saying all is fine can proceed to process form blah blah.
I'm essentially wanting somebody to select a bunch of events in a form, query 1 then finds all the days and times those events happen and check that none of them exist in the MyTimetable table.

I must admit I dont know all that much about SQL, which is why I hope someone can show me the light. I have a script almost finished, however I have no idea how to have it trim database entries that are older than, say, 90 days. Any ideas?

I have a table with a load of orphaned records (I know... poor design)
I'm trying to get rid of them, but I'm having a brain cramp.
I need to delete all the records from the table "Floor_Stock" that
would be returned by this select statement:
SELECT FLOOR_STOCK.PRODUCT, FLOOR_STOCK.SITE
FROM PRODUCT_MASTER INNER JOIN
FLOOR_STOCK ON PRODUCT_MASTER.PRODUCT =
FLOOR_STOCK.PRODUCT LEFT OUTER JOIN
BOD_HEADER ON FLOOR_STOCK.PRODUCT =
BOD_HEADER.PRODUCT AND FLOOR_STOCK.SITE =
BOD_HEADER.SITE
WHERE (BOD_HEADER.BOD_INDEX IS NULL) AND
(PRODUCT_MASTER.PROD_TYPE IN ('f', 'n', 'k', 'b', 'l', 's'))
I was thinking along the lines of:
DELETE FROM FLOOR_STOCK INNER JOIN
(SELECT FLOOR_STOCK. PRODUCT, FLOOR_STOCK.SITE
FROM PRODUCT_MASTER INNER JOIN
FLOOR_STOCK ON PRODUCT_MASTER. PRODUCT =
FLOOR_STOCK.PRODUCT
LEFT OUTER JOIN BOD_HEADER ON FLOOR_STOCK. PRODUCT =
BOD_HEADER. PRODUCT AND FLOOR_STOCK.SITE = BOD_HEADER.SITE
WHERE (BOD_HEADER.BOD_INDEX IS NULL) AND
(PRODUCT_MASTER.PROD_TYPE IN ('f', 'n', 'k', 'b', 'l', 's'))) F ON
FLOOR_STOCK. PRODUCT = F. PRODUCT
AND FLOOR_STOCK.SITE = F.SITE
... but Sql Server just laughs at me: "Incorrect Syntax near the keyword INNER"

Hey all,
Here is the scenario. I'm working with two tables:
Contact1
Conthist
Contact1 contains basic contact information and conthist contains history records for those contacts. Conthist can hold many records related to a single contact1 record.
The link between the two tables is a column called accountno.
I'm trying to delete any records in conthist that have an accountno that does not exist in contact1. The queries that I've tried keep returning conthist records that do actually have a matching accountno.
Any help would be appreciated.
Thanks,
Tony

Whenever I try to delete records from a table joined to another table, like so:
DELETE [tblTransaction Detail Local] FROM [tblTransaction Detail Local], [tblTransaction Header] WHERE ([tblTransaction Detail Local].[Transaction ID] = [tblTransaction Header].[Transaction ID]) AND ([tblTransaction Header].[Computer ID] = 3)
I get the error:
Major Error 0x80040E14, Minor Error 25501
> DELETE [tblTransaction Detail Local] FROM [tblTransaction Detail Local], [tblTransaction Header] WHERE ([tblTransaction Detail Local].[Transaction ID] = [tblTransaction Header].[Transaction ID]) AND ([tblTransaction Header].[Computer ID] = 3)
There was an error parsing the query. [ Token line number = 1,Token line offset = 38,Token in error = FROM ]
This is an SQL CE database, and SQL Server Management Studio. Any ideas?

I have a couple SQL tables that have been appended to daily over the last two years. There is now about 50,000,000 records in the table. Does anyone know the fastest way to delete records before a certain date to shorten these tables? Delete queries and everything else I've tried is taking way too long.

Apparently, deleting 7,000,000 records from a table of about 20,000,000 is not advisable. We were able to take orders at 8:00AM, but not at 7:59.
So, what's the best way of going about deleting a large number of records? Pretty basic lookup table, no relationships with other tables, 12 or so address-type fields, 4 or 5 simple indexes. I can take it down for a weekend or night, if needed.
DTS the ones to keep to another table, drop the old and rename the new table?
Bulk copy out, truncate and bring back in?
DTS to text, truncate and import back?
Other ways?
Never worked with such a large table and need a little experienced guidance.
Thanks for the help

My Web Host does not provide administrative privilages to the SQL server I have access to. I would like to delete tens of thousands of records from two of my tables without writing to the Transaction Log. Is what I'm trying to do is delete these records quickly without utilizing any of the alotted space my web host has set aside for my transaction log (they give me 50 mb and I go way over that when I run a DELETE statement)
What is the best way to do this?

I have a problem where records in underlying tables of a dataview are being deleted (seemingly at random)
For example.
CREATE TABLE [Employee] (Id int, Name varchar(50))
CREATE TABLE [Company] (Id int, Name varchar(50))
CREATE TABLE [EmployeeCompany] (CompanyId int, EmployeeId int)
CREATE VIEW [dvEmployee]
AS
SELECT *
FROM [Employee] INNER JOIN [EmployeeCompany]
ON [Employee].[Id] = [EmployeeCompany].[EmployeeId]
CREATE TRIGGER [dvEmployeeUpdate]
ON [dbo].[dvEmployee]
INSTEAD OF UPDATE
AS
BEGIN
UPDATE EmployeeCompany
SET Status = INSERTED.Status
FROM EmployeeCompany, INSERTED
WHERE EmployeeCompany.CompanyId = INSERTED.CompanyId
AND EmployeeCompany.EmployeeId = INSERTED.EmployeeId
END
Because the column [Status] is a t-sql keyword, does the fact that the trigger contains the line "SET Status = ..." without saying "SET [Status] = ..." mean that I could lose records in the EmployeeCompany table?
Reason I'm asking is we have an already designed database that is littered with columns named the same as sql keywords (almost every table has a [Status] column, and there are many [Password] columns). When using a dataview on these tables, triggers exist that aren't putting the [] around these column names (the same as my dvEmployeeUpdate trigger above), and somehow we are seemingly randomly losing records. It is very rare, and they are getting completely deleted, and it seems to be the tables that contain the keyword columns and are used in dataviews with instead of triggers that don't put [] around the column names. Nowhere in any trigger or stored procedure is there a DELETE FROM on these tables, and the software running on the database uses only the data views, and doesn't directly access the underlying tables.
I've been going through all of the code adding the [], but my question is simply whether or not anyone has heard of this causing the deletion of any records, or whether there may be something else going on that I should be looking into?
