I am looking for an alternate logic for below-mentioned code where I am inserting into a table and having left join with the same table
insert TABLE1([ID],[Key],[Return])
select distinct a.[ID],cat1,cat2 from

and a.Cat1 = o.[Key]
and a.cat2 = o.[return]
where [key] is null order by ID

when i use left outer join, i only record one employee per date.
Below is my table structure. And I am inserting data from other temp table.
CREATE TABLE #revf (
[Cusip] [VARCHAR](50) NULL, [sponfID] [VARCHAR](max) NULL, GroupSeries [VARCHAR](max) NULL, [tran] [VARCHAR](max) NULL, [AddDate] [VARCHAR](max) NULL, [SetDate] [VARCHAR](max) NULL, [PoolNumber] [VARCHAR](max) NULL, [Aggregate] [VARCHAR](max) NULL, [Price] [VARCHAR](max) NULL, [NetAmount] [VARCHAR](max) NULL,
[Code] ....
Now in a next step I am deleting the records from #revf table. Please see the delete code below
DELETE
FROM #revf
WHERE fi_gnmaid IN (
SELECT DISTINCT r2.fi_gnmaid
FROM #revf r1, #revf r2
[Code] ...
I don't want to create this #rev table so that i can avoid the delete statement. But data should not affect. Can i rewrite the above as below:
SELECT [Cusip], [sponfID], GroupSeries, [tran], [AddDate], [SetDate], [PoolNumber], [Aggregate], [Price], [NetAmount], [Interest],
[Coupon], [TradeDate], [ReversalDate], [Description], [ImportDate], MAX([fi_gnmaid]) AS Fi_GNMAID, accounttype, [IgnoreFlag], [IgnoreReason], IncludeReversals, DatasetID, [DeloitteTaxComments], [ReconciliationID],
[Code] ....
If my above statement is wrong . Where i can improve here? And actually i am getting 4 rows difference.
INSERT
INTO [Table2Distinct]
([CLAIM_NUMBER]
,[ACCIDENT_DATE]
[code]....
I used the above query and it still inserts all the duplicate records. What is wrong with my statement?
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

Select

,a.[AccountId]
,[Name]
,[new_LocationID]
,[ws_name]
,[new_BillingManageruserName]
,[new_AreaServiceManName]

I know people use ROW_NUMBER() function to do the pagination but my below two query is bit complex. Sohow to use pagination there ? I used ROW_NUMBER() OVER(ORDER BY IsNull(A.OEReference, B.OEReference) ASC) as Line in one but not sure am i right or wrong.
IF IsNull(@GroupID,'') = ''
SELECT IsNull(PartGroupName, 'UnMapped') AS PartGroupName,

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 am working on moving information from one of our databases into a newer one the company has recently setup. I am working in MS SQL Server 2012 and am trying to Inset/Update (depending on the information) a part table. I will list the two tables I am working on as Old (where I am getting the information) and New (where it is to be inserted into).
The old table has about 250 columns of information, most of which is not needed. The needed information is as follows: Name, ID, Component1, Component1_PIN,Component1_SN, Component1_Description, Component2, Component2_PIN, Component2_SN. The component section repeats up to Component12.
The new table has columns setup as such: Name, ID, Case, CasePIN, CaseSN, Case_Desc, Processor, ProcessorPIN, ProcessorSN, Processor_Description, Memory, MemoryPIN, MemorySN, Memory_Description, etc.
The issue I am having is that in the old table each component can have Case, Processor, Memory, etc in that one column. I need to insert Case, Memory, etc into the correct column in the new table while keeping intact the rest of the information.
Example:
Old Table
Name | ID | Component1 | Component1_PIN | Component1_SN | Component1_Description | Component2 | Component2_PIN | Component2_SN | Component2_Description
Nest8 | 5682 | Case | 901834 | 237848117 | Black, rectangular | Memory | 9081234 | 5398798134 | NULL
Nest8 | 5978 | Case | 901463 | 237848138 | Black, rectangular | Processor | 2394875 | 2903857809 | Bad
Reds3 | 5683 | Memory | 2405 | 89752342 | Crucial | HardDrive | 92387595 | 457982234 | NULL
Bass | 5644 | HardDrive | 79872346 | 5321675789 | NULL | Case | 10984528 | 3498769872 | NULL
I am not sure how to loop through and grab each part and place it in the column it needs to be while keeping it with the ID.
I have 2 tables: Source Table - IncidentDimNew and Destination Table - IncidentDimNew with identical columns: Id and CreatedDate but the data is different.
I would like to insert distinct data from those 2 columns of 1st table into the same 2 columns into the 2nd table but I onlt want to replace the values in the 2nd table where the Created Date is > 2015-04
I compiled the code in order to get the information I want from 2 tables:
Source Table
SELECT
COUNT(Id),
LEFT(CONVERT(VARCHAR(10)), CreatedDate, 126), 7)
FROM
IncidentDimNew
[Code] ...
This is the code I wrote in order to do it
INSERT INTO IncidentDim
[Id]
,[CreatedDate]
SELECT
[Id]
,[CreatedDate]
FROM
IncidentDimNew
where left(CONVERT(VARCHAR(10), CreatedDate, 126),7) > '2015-04'
GO
But what it does it's gives the SUM of the values in the corresponding rows where the values are not null which I don't want.
So how do I leave the values as is from table IncidentDim and insert new values as it is from IncidentDimNew where the Created Date is > 2015-04?

Suppose you have a simple DML "execute as..." trigger that looks like this:
CREATE TRIGGER dbo.myTrigger
ON dbo.myTable
WITH Execute As Owner
AFTER INSERT
AS
[code]...
which runs as "owner" so that the user inserting into "myTable" won't have the privs to edit the audit table.How does one capture the identity of the user whose insert statement caused the trigger to fire? I've tried "current_user" and "system_user" without success when "execute as ..." is used: they each return a value not related to the identity of the user running the original insert.without an "execute as" clause, what prevents a user from adding to or editing the audit table directly?

Hi, I have a table in which I will insert several redundant data. Don't ask why, is Integration services, it only reads data and inserts it in a SQL table. THis way, I have a SQL table with several lines repeating them selves. What I want to do is create a procedure that reads the distinct data and inserts it in another table, but my problem is that I am not able to select data line by line on the original table to save it in local variables and insert it on the another table, I just can select the last line. I've tried a while cycle but no succeed. Here is my code: create proc insertLocalizationASdeclare @idAp int, @macAp varchar(20), @floorAp varchar(2), @building varchar(30), @department varchar(30)select @idAp = idAp from OLTPLocalization where idAp not in (select idAp from dimLocalization)select @macAp=macAp,@floorAp=floorAp,@building=building,@department=department from OLTPLocalizationif (@idAp <> null)beginInsert into dimLocalization VALUES(@idAp,@macAp,@floorAp,@building,@department)endGO This only inserts the last line in the "oltpLocalization" table. O the other hand, like this:create proc aaaaasdeclare @idAp as int, @macAp as varchar(50), @floorAp as int, @building as varchar(50), @department as varchar(50)while exists (select distinct(idAp) from OLTPLocalization)begin select @idAp =idAp from OLTPLocalization where idAp not in (select idAp from dimLocalization) select @macAp = macAp from OLTPLocalization where idAp = @idAp select @building = building from OLTPLocalization where idAp = @idAp select @department = department from OLTPLocalization where idAP = @idApif (@idAp <> null)begin insert into dimLocalization values(@idAp,@macAp,@floorAp,@building,@department)endendgo this retrieves every distinct idAp in each increment on the while statement. The interess of the while is really selecting each different line in the OLTPLocalization table. I did not find any foreach or for each statement, is there any way to select distinct line by line in a sql table and save each column result in variables, to then insert them in another table? I've also thought about web service, that reads the distinct data from the oltpLocalization into a dataset, and then inserts this data into the dimLocalization table. Is there anything I can do?Any guess?Really needing a hand here!Thanks a lot!

Hi,
I'm working on a database for a financial client and part of what i need to do is calculate a value from two separate rows in the same table and insert the result in the same table as a new row. I have a way of doing so but i consider it to be extremely inelegant and i'm hoping there's a better way of doing it. A description of the existing database schema (which i have control over) will help in explaining the problem:
Table Name: metrics_ladder
id security_id metric_id value
1 3 80 125.45
2 3 81 548.45
3 3 82 145.14
4 3 83 123.32
6 4 80 453.75
7 4 81 234.23
8 4 82 675.42
.
.
.
Table Name: metric_details
id metric_id metric_type_id metric_name
1 80 2 Fiscal Enterprise Value Historic Year 1
2 81 2 Fiscal Enterprise Value Current Fiscal Year
3 82 2 Fiscal Enterprise value Forward Fiscal year 1
4 83 2 Fiscal Enterprise Value Forward Fiscal Year 2
5 101 3 Calendar Enterprise value Historic Year 1
6 102 3 Calendar Enterprise Value Current Fiscal Year
5 103 3 Calendar Enterprise value Forward Year 1
6 104 3 Calendar Enterprise Value Forward Year 2
Table Name: metric_type_details
id metric_type_id metric_type_name
1 1 Raw
2 2 Fiscal
3 3 Calendar
4 4 Calculated
The problem scenario is the following: Because a certain number of the securities have a fiscal year end that is different to the calendar end in addition to having fiscal data (such as fiscal enterprise value and fiscal earnings etc...) for each security i also need to store calendarised data. What this means is that if security with security_id = 3 has a fiscal year end of October then using rows with ids = 1, 2, 3 and 4 from the metrics_ladder table i need to calculate metrics with metric_id = 83, 84, 85 and 86 (as described in the metric_details table) and insert the following 4 new records into metrics_ladder:
id security_id metric_id value
1 3 101 <calculated value>
2 3 102 <calculated value>
3 3 103 <calculated value>
4 3 104 <calculated value>
Metric with metric_id = 101 (Calendar Enterprise value Historic Year 1) will be calculated by taking 10/12 of the value for metric_id 80 plus 2/12 of the value for metric_id 81.
Similarly, metric_id 102 will be equal to 10/12 of the value for metric_id 81 plus 2/12 of the value for metric_id 82,
metric_id 103 will be equal to 10/12 of the value for metric_id 82 plus 2/12 of the value for metric_id 83 and finally
metric_id 104 will be NULL (determined by business requirements as there is no data for forward year 3 to use).
As i could think of no better way of doing this (and hence the reason for this thread) I am currently achieving this by pivoting the relevant data from the metrics_ladder so that the required data for each security is in one row, storing the result in a new column then unpivoting again to store the result in the metrics_ladder table. So the above data in nmetrics_ladder becomes:
security_id 80 81 82 83 101 102
----------- -- -- -- -- -- --
3 125.45 548.45 145.14 123.32 <calculated value> <calculated value>
4 ...
.
.
.
which is then unpivoted.
The SQL that achieves this is more or less as follows:
*********
START SQL
*********
declare @calendar_averages table (security_id int, [101] decimal(38,19), [102] decimal(38,19), [103] decimal(38,19), [104] decimal(38,19),etc...)

..
..
from temp
pivot
(

) as temppivot
inner join company_details cd on temppivot.security_id = cd.security_id
*********
END SQL
*********
The result then needs to be unpivoted and stored in metrics_ladder.
And FINALLY, the question! Is there a more elegant way of achieving this??? I have complete control over the database schema so if creating mapping tables or anything along those lines would help it is possible. Also, is SQL not really suited for such operations and would it therefore be better done in C#/VB.NET.
Many thanks (if you've read this far!)

How to create Table A by inserting all the data from Table B?
Cheers,

How do i insert data into multiple tables. Lets say i have 2 tables: Schedules and Event
Schedules data is entered into the Schedules Table first
then now i need to insert Event table's data by refrencing the (PK ID) from the schedules table.
How do i insert data into Event table referencing the (PK ID) from Schedules Table ?
Fields inside each of the tables can be found below:
Event Table
(PK,FK) ScheduleID
EventTitle
AccountManager
Presenter
EventStatus
Comment
Schedule Table
(PK) ID
AletrnateID
name
UserID
UserName
StartTime
EndTime
ReserveSource
Status
StatusRetry
NextStatusDateTime
StatusRemarks
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
FROMCompanies
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
WHERE Companies.name LIKE 'abc'
ANDCompanies.status_indicator like 'Current'

But id 12 is not shown at allbecause it doesn't have a record for 2004!! I don't know why 'cause Iouterjoined the tables.It works perfectly when I have two distinct tables for each year (forinstance contract_2005 and contract_2004).

I only want to merge the columns with Primary_IDs 1111 & 3333 to have the same Secondary_ID values, without duplicating any similar Secondary_ID values between the 2 which I've marked in red below.
Code:
TABLE A
==========
Primary_ID | Secondary_ID
1111 | 1
1111 | 2
1111 | 3
1111 | 4
3333 | 1
3333 | 2
3333 | 10
3333 | 20
3333 | 100
3333 | 200
5555 | 12
5555 | 34
7777 | 56
7777 | 78
Code:
NEW TABLE A
==========
Primary_ID | Secondary_ID
1111 | 1
1111 | 2
1111 | 3
1111 | 4
1111 | 10

I am trying to convert the following sql to linq
SELECT R.UserID,R.Cntrl_nbr FROM User R
WHERE (
R.REG_ID=
(SELECT MAX(B.REG_ID)
FROM User B
WHERE R.UserID = B.UserID )
The linq I am using is
var query = (from n2 in q1
where
n2.RegServiceTs == (q1.Where(c1 => c1.UserID == n2.UserID).Max(c2 => c2.REG_ID))
select n2).SingleOrDefault();
This is slow and is there a better way to do this?
I need the last year sales(lastyearsales), first name, last name and city from the following tables. The relation is as following:
SalesPerson<->Employee <- EmployeeAddress<-Address
SalesPerson<->Employee <-Contact
SalesPerson Table
1.SalesPersonID
lastyearsales
Employee Table
1.EmployeeID
2.ContactID
Contact Table
2.ContactID
FirstName
LastName
EmployeeAddress Table
1.EmployeeID
3.AddressID
Address
3.AddressID
City
And my answer:
Select: C1.firstname, C1.lastname, SP.lastyearsales, A.city
From: SalesPerson as SP join Employee as E1 on Sp.salespersonID = E1.EmployeeID
Right Join Employee as E2 on E1.EmployeeID=E2.EmployeeID join Address as A on E2.AddressID = A.AddressID
Right Join Employee Contact as C1 on E1.ContactID = C1.ContactID
