I have a calendar table against entire year 2015 with each day with 2 flag,
1. WK_DT_IN == except Satarday and Sunday, value is "Y", for Sat/Sun, value is "N"
2. HOL_DT_IN == value will only be "Y" only for holiday, example for '2015-01-01' date, it's value is "Y"
DECLARE @CAL TABLE (CAL_DT DATE, WK_DT_IN CHAR(1), HOL_DT_IN CHAR(1))
INSERT INTO @CAL VALUES ('2015-01-01', 'Y', 'Y'), ('2015-01-02', 'Y', 'N'),('2015-01-03', 'N', 'N'),
('2015-01-04', 'N', 'N'), ('2015-01-05', 'Y', 'N'), ('2015-01-06', 'Y', 'N'), ('2015-01-07', 'Y', 'N')
We have a given date, example '2015-01-01', I need to find out a date after 2 business days? I can think of loop, but will it work.
I need to exclude date which having HOL_DT_IN = "Y" and WK_DT_IN = "N".

I created a dbo.Calendar table that stores dates and a work day flag (1=work day, 0=non-work day) so I can use it to calculate the next business date from a date using a function. I'm using a while group to count only the work days and a couple other internal variables but I'm not sure if I can even use them in a function.
Assuming Sats & Suns are all non-work days in April 2014, if my @WorkDays = 10 for 10 work days and my @DateFromValue - 4/1/2014, I would expect my return date to be 4/15/2014.
------ Messages after I click execute on my query window that has my function ------------------------------------------------------
Msg 444, Level 16, State 2, Procedure FGetWorkDate, Line 19
Select statements included within a function cannot return data to a client.

I have a lookup table with 4 levels of codes like follows:
create table #RiskElementCategory(
[RiskElementCategoryCode] [nchar](5),
[RiskElementCategoryCodeDsc [nvarchar](50),
[RiskElementCategoryCode_2] [nchar](5),
[RiskElementCategoryLevel2Dsc] [nvarchar](50),
[Code] ...
Along with some other rows with the same format. I need to join to this table using a RiskElementCode that I get from the Source system. The trick is that it can be at any level, but I don't know which level it is at. So what I have to do is somehow get the correct row from the lookup table based on the code from the source to get the correct level.
So for Example, If i receive the RiskElementCode of 'SSR', that is in column RiskElementCategoryCode_3 so I need the row that has 'NA' for anything after RiskElementCategoryCode_3 where RiskElementCategoryCode_3 = 'SSR'. If i get 'DFR' I need to get the row where RiskElementCategoryCode_4 = 'DFR' since there are no levels deeper than 4 i don't need to check anything else. If I get 'PRR', then I need the row where RiskElementCategoryCode = 'PRR' and code_2, code_3 and code_4 = 'NA'.
So besides getting the correct row based on the code, i need to get the correct row based on the level where the next levels are 'NA'. I should only get 1 row each time.

I have a table (can't change the schema of it since it is part of an off the shelf app ) that has columns for individuals which I need to extract several pieces of information, essentially Phone, Email Address, etc. See U1 - U6
What is a better way to return this information rather than multiple joins?
Select
[AccountNumber]
,a.[AccountId]
,[Name]
,[new_LocationID]
,[ws_name]
,[new_BillingManageruserName]
,[new_AreaServiceManName]

I have a large table with 100 Million records that has around 1 million duplicate records that need to be deleted.
I am running a script that creates a staging table called,DuplicateTable that collects all the duplicates and then I want to write a an effecient delete statement.
Is it possible to write something like:
delete from OrigTable O join DuplicateTable D
on O.Key = D.key
Or do I have to run a loop on the DuplicateTable and run a delete statement record by record ?

I have an Employee table that has
EmployeeID (PK)
SupervisorID (which is really just another EmployeeID)
..random junk...
Now that part makes sense, everyone gets one and only one boss.
Their boss can change, and therefore the SupervisorID would be updated.
Now I have an EmployeeEvals table that has quarterly evaluation data.
I want to relate these two tables.
Eval table has
EvalID (PK)
ReviewedEmployeeID (the one being evaluated)
SupervisorID (the one doing the evaluation)
Now I need to link this back to the employee table (at least I think I do).
So I would want to relate it by the ReviewedEmployeeID going back to EmployeeID in the employee table and I also want the SupervisorID to do the same...
But of course that won't work because that would seem to indicate that a single record on the Employees table (say EmployeeID 55) should have a matching (or could) record in the Eval table that would look like
EvalID: 12345
ReviewedEmployeeID: 55
SupervisorID: 55
which of course wouldn't happen as an employee wouldn't evaluate themself.
How do I handle the relationships for this properly?
Do I just not link the SupervisorID back to anything?

I have a table history of Employee data.
id | EmpNo | EmpName | MobileNo | Email | EmpSSS | UpdateDate | UpdateUser
I have to make a stored procedure that will show the history and changes made to a given EmpNo, with the UpdateDate, UpdateUser and indicate which field is modified. Ex. Employee Mobile number was changed from '134151235' to '23523657'.
Result must be:
EmpNo | UpdateDate | UpdateUser | Field changed | Change from | change to

Hello all,
I would like to populate a calendar table similar to the one used in the foodmart2005 sample database. In this table the day of the week, month, and year are recorded as well as additional data which I do not require.
If possible I would like to populate the table with 10 years of data starting with 2007.
Secondly would 10 years of data make the table to large?
Thank you for any thoughts you may have.

Inside my SQL 2005 database I have a SmallDateTime with the layout "mm/dd/yyyy hh:mm:ss AM/PM" and then on a selected date of a calendar control it returns the date with 12:00:00 AM which obviously doesn't match with my database's time.
So, I'm looking for a way to drop the time off completely (for the query purpose) the database date when running a select statement. I don't want to touch SQL table data by modifying it, I just want to be able to query sql table using calendar control. Does anyone now how to accomplish this? Thank you in advance. - Nietzky

Hello,
I'm trying to get my head around this, any help would be appreciated. I have a calendar table I've created for use with a billing report. It would be great to have a column that had the first day of the month for every row entry (so for every row representing a day in february, that row would have February 1st, in datetime format). I thought it would be easy to create and populate this column at first, but I'm finding it much more difficult. Does anyone know how to populate this column?
Thanks in advance,
Andy

Say you have a fact table with a few columns that all reference the same key column in a dimension table, you want to write a view to return the information for those keys?
USE MyTestDB;
GO
SET NOCOUNT ON;
IF OBJECT_ID ('dbo.FactTemp' ,'U') IS NOT NULL
DROP TABLE dbo.FactTemp;
[Code] ....
I'm using very small data at the moment, and the query plan and statistics don't really say which way.

I have a date that I need to add 'n' number of business days to. I have a calendar table that has a 'IsBusinessDay' flag, so it would be good if I was able to use this to get what I need. I've tried to use the 'LEAD' function in the following way;
SELECT A. Date, B.DatePlus3BusinessDays
FROM TableA A
LEFT JOIN (Select DateKey, LEAD(DateKey,3) OVER (ORDER BY datekey) AS DatePlus3BusinessDays FROM Calendar WHERE IsBusinessDay = 1) B ON A.DateKey = B.DateKey
Problem with this is that because I am filtering the Calendar for business days only, when there is a date that is not a business day in TableA, a NULL is being returned.
Is there any way to do a conditional LEAD, so it skips rows that are not business days? Or do I have do go with a completely different approach?

I know how to do this in Excel, but not sure about Power Pivot. Our fire department works on a 24 hour shift that starts at 0700 each morning. I want to look up what shift is working depending on the date and time of dispatch. In Excel, I would do a look up table, but instead of using false() as the last parameter, I would choose true().
I am not sure if this would be best created as a calculated column in the table that holds the incident date and time values, or have a separate table and create a relationship to use the shift in the rows/columns of my pivot table.

I have tables Companies, CompaniesDetails (the company branches), Addresses and Companies_Addresses.
The addresses table contain street and city while the Companies_Addresses has the keys for both companies and branches ,i.e., they are linked to Companies and CompaniesDetails via CompanyID and CompanyDetailID and to Addresses via addressID.
Companies_Addresses
id (PK)
companyID (FK)
companyDetailID (FK)
addressID (FK)
I am able to get the branch address at the moment with this code but I would like to get the company address as well using a single select statement.
Code:
SELECT DISTINCTAddresses.city as branchCity, Addresses.street as branchStreet

LEFT JOINCompaniesDetails AS cd ON companies.companyID = cd.companyID
LEFT JOINCompanies_Addresses AS c ON c.companyDetailID = cd.companyDetailID
LEFT JOINAddresses ON c.addressID = Addresses.addressID

In the following example, I have a "Person" table, and a many-to-many "Relationship" table which stores the r/ship between any two people:
[Person] [Relshp]
---------------- ---------------------
| PersonId PK|<-.-. | RelshpId PK |
| PersonName | '-| PersonId |
---------------- '--| RelatedToPersonId |
| RelationshipType |
---------------------
There are 2 FK constraints, linking
1. [Relshp].[PersonId] to primary key [Person].[PersonId], and
2. [Relshp].[RelatedToPersonId] to primary key [Person].[PersonId].
What kind of index structure would best support those FK constraints?
Would it be:
a) One combined index:
CREATE INDEX IX_Relshp ON Relshp (PersonId, RelatedToPersonId)
or
b) Two indexes:
CREATE INDEX IX_RelshpP ON Relshp (PersonId)
CREATE INDEX IX_RelshpR ON Relshp (RelatedToPersonId)
or
c) Two "mirrored" combined indexes:
CREATE INDEX IX_RelshpP ON Relshp (PersonId, RelatedToPersonId)
CREATE INDEX IX_RelshpR ON Relshp (RelatedToPersonId, PersonId)

Hi,
Sorry if this has been asked before, I looked through the FAQ but could not find an answer to the following.
I have a Project table which contains amongst other fields, a CreatedByID field and a LastModifiedByID field. Both these fields point to a User table. What I would like to do is get the two usernames from a query on the project table.
I know how to get one usename using the following Sql command but how do I get access to the second username ?
SELECT Project.Name,User.Username FROM Project,User WHERE Project.ID=@id AND User.ID = Project.CreatedByID;
I hope my ramblings make sense

use default pubs database in sqlserver2000.
use authors table and publishers table.
Write a query to list first name, last of all authors
and name of the publisher (if any) present in the same city
as the author. If no publisher is present in the city
where the author is located then the column should contain a
NULL value. If there is more than one publisher in the city
where the author is located, then the details of
the author are to be repeated for each publisher.
but there is no field match between authors table and publishers table.
