Insert / Update In Master Table And Also Save A History Of Changed Records : Using Data Flow/simple Sql Queries

Feb 9, 2007

Hi,

My scenario:

I have a master securities table which has 7 fields. As a part of the daily process I am uploading flat files into database tables. The flat files contains the master(static) security data as well as the analytics(transaction) data. I need to

1) separate the master (static) data from the flat files,

2) check whether that data is present in the master table, if not then insert that data into the master table

3) If data present then move that existing record to an history table and then update the main master table.

All the 7 fields need to be checked to uniquely identify a single record in the master table.

How can this be done? Whether we can us a combination of data flow items or write a sql procedure to do all this.

Thanks in advance for your help.

Regards,

$wapnil

T-SQL (SS2K8) :: How To Select Records Only When Their Status Has Been Changed

Jun 9, 2015

I have a product table and my task is to select only the products that had been paid for, but later their status has been changed.

I need to report the original paid date, the most recent status, and most recent updated date. Here is the sample table:

CREATE TABLE #Products (primKey int, productId int, productName varchar(100), productStatus varchar(50), logDate datetime )

Insert into #Products(primKey, productId, productName, productStatus, logDate)

Values
(1, 201, 'pen', 'received', '01/01/2011'),
(2, 201, 'pen', 'sold', '01/02/2011'),
(3, 201, 'pen', 'paid', '01/03/2011'),
(4, 201, 'pen', 'returned', '01/04/2011'),
(5, 201, 'pen', 'refurbished', '01/05/2011'),
(6, 202, 'pencil', 'received', '01/06/2011'),
(7, 202, 'pencil', 'sold', '01/07/2011'),
(8, 202, 'pencil', 'paid', '01/08/2011'),
(9, 201, 'pen', 'sold', '01/09/2011'),
(10, 201, 'pen', 'paid', '01/10/2011')

/* temp table records */
Select * From #Products order by productId

/* The desired outcomes would be showing only the Record 3 and 10.

This is a "fake" query to get the results:
*/
Select * From #Products Where primKey in (3, 10) order by productId

How Do I Get The Most Recent Data From A Table?

Aug 27, 2007



I'm trying to create a stored procedure from a join of two tables. One table holds a list of containers, and the other table holds the history of the contents of those containers. All I want is to retrive the most recent history for each container. For example, the containers table has the container number and name, and the history table has the
volume in the container and the date and time of the measurements. There can be any number of measurements, but I only want the most recent one.

Normally, I would just create a cursor that holds a list of the containers and some blank fields, and then loop through it, retrieving the most recent record one by one, but I don't know how to do that in Transact-SQL. Also, I thought maybe some SQL wizard out there might know of a way to do it with a simple select statement.

Select Most Recent Customer Record From Table Only?

Nov 6, 2007

If I have a table structure similar to the following, how might I query it to obtain the Transaction ID, Transaction Date, and Customer Name for the most recent transaction per customer only:


TransactionTable:
TransactionID TransactionDate TransactionType CustomerName
1 10/1/07 1 Bob
2 8/30/07 2 Janet
3 9/17/07 1 Mike
4 9/25/07 1 Bob


The following query will return all records in the table other than Janets...not what I want:
SELECT Transaction ID, TransactionDate, CustomerName
FROM TransactionTable
WHERE TransactionType = 1
ORDER BY TransactionDate DESC


The following query will return all records in the table other than Janets again, because DISTINCT will use the combo of TransactionID, TransactionDate, and Customer name for uniqueness...not what I want:
SELECT DISTINCT Transaction ID, TransactionDate, CustomerName
FROM TransactionTable
WHERE TransactionType = 1
ORDER BY TransactionDate DESC

The results set I'm looking for would be the following, where only the most recent entry per customer with TransactionType 1 is returned (i.e. one record for Bob):


TransactionTable:
TransactionID TransactionDate CustomerName
1 10/1/07 Bob
3 9/17/07 Mike


I believe I need an appropriate subquery to yield the results I desire, but can't sort out what it is? I do not want to execute multiple queries but subqueries are fine. Unfortunately there's probably an easy answer that my brain is not currently generating. Any help would be appreciated.


Note, this is not a real table, but a sample to illustrate the concept for the query I need.

Thanks.

Find Most Recent Record In Table According To Date Field

Sep 19, 2015

The "Last" function in the query below (line 4 & 5) is not exactly what I'm after. The last function finds the last record in that table, but i need to find the most recent record in the table according to a date field.

Code:
SELECT
tblinmate.statusid,
tblinmate.activedate,
Last(tblclassificationhistory.classificationid) AS LastOfclassificationID,
Last(tblsquadhistory.squadid) AS LastOfsquadID,
tblperson.firstname,
tblperson.middlename,
tblperson.lastname,

[Code] ....

The query below finds the most recent record in a table according to a date field, my problem is i dont know how to integrate this Query into the above to replace the "Last" function

Code:
SELECT a.inmateID,
a.classificationID,
b.max_date
FROM (
SELECT tblClassificationHistory.inmateID,
tblClassificationHistory.classificationID,

insert into BlogAssociations values (3,'',1);
insert into BlogAssociations values (12,'',1);



There is my above sql script, i'm currently using mysql at home to test things but will convert to work in mssql.
I need to get associated BlogID for Certain ChannelID from the BlogAssociations table.
Then using those BlogID's that it finds for let just say ChannelID "1" list off the 3 most recent EpisodeID's from the Episodes Table per each BlogID.
So if ChannelID "1" has four BlogID's associated with it then in the Episodes table list off the recent 3 EpisodeIDs for BlogID "3", then the 3 most recent EpisodeIDs for BlogID "5" and so on and so on.

I have this which kind of does what I want:

Code:


select
e.BlogID, e.EpisodeID, e.other
FROM
episodes e, BlogAssociations ba
WHERE
e.BlogID = ba.BlogID and ba.ChannelID = '1'
ORDER BY
e.EpisodeID DESC;



It returns:

Code:


+--------+-----------+---------------------+
| BlogID | EpisodeID | other |
+--------+-----------+---------------------+
| 12 | 17 | Episode 17, blog 12 |
| 12 | 16 | Episode 16, blog 12 |
| 12 | 15 | Episode 15, blog 12 |
| 12 | 14 | Episode 14, blog 12 |
| 12 | 13 | Episode 13, blog 12 |
| 3 | 4 | Episode 4, blog 3 |
| 3 | 3 | Episode 3, blog 3 |
| 3 | 2 | Episode 2, blog 3 |
| 3 | 1 | Episode 1, blog 3 |
+--------+-----------+---------------------+



But as you can see it lists off 5 of the Episodes for BlogID "12", I only want the most recent 3 as previously stated. It also lists off more than 3 Episodes for BlogID "3". How in the world do I go about doing this?
I'm making this a stored procedure so I can't use php otherwise I wouldn't even be posting

Thanks so much!

SQL Server 2012 :: How To Get Most Recent And Oldest From Joins To A Child Table

Jul 23, 2014

I have the following tables in my DB

Employee table - This table has EmployeeID, Name, DOB.

EmployeeDesignation table - 1 Employee can have many designations with each having an effective date. There is no flag to indicate which among multiples is the current entry. You can only figure it out by the newest/oldest EffectiveDate. I want to get the most recent and the oldest for each employee.

EmployeeSalaryHistory table - Structure/Design is similar to EmployeeDesignation table. I want to get the starting salary and current salary for each employee.

I want my query to output me the following fields...

EmployeeID
EmployeeName
EmployeeDOB
EmployeeStartingDesignation
EmployeeCurrentDesignation
EmployeeStartingSalary
EmployeeCurrentSalary

Here is a piece of code to generate sample data sets

DECLARE @Employee TABLE (EmployeeID INT, EmployeeName VARCHAR (100), EmployeeDOB DATE)
INSERT @Employee VALUES (101, 'James Bond', '07/07/1945'), (102, 'Tanned Tarzan', '12/13/1955'), (103, 'Dracula Transylvanian', '10/22/1967')

DECLARE @EmployeeDesignation TABLE (EmployeeID INT, Designation VARCHAR (100), EffectiveDate DATE)
INSERT @EmployeeDesignation VALUES (101, 'Bond Intern', '01/01/1970'), (101, 'Bond Trainee', '01/01/1975'), (101, 'Bond...James Bond', '01/01/1985')

[Code] ....

Currently, I have a query to get this done which looks as below. Since I have more than 8K employees with each having multiple Designation and Salary entries, my query is taking forever.

selecte.EmployeeID, e.EmployeeName, e.EmployeeDOB,
(select top 1 Designation from @EmployeeDesignation ed where ed.EmployeeID = e.EmployeeID Order By EffectiveDate) EmployeeStartingDesignation,
(select top 1 Designation from @EmployeeDesignation ed where ed.EmployeeID = e.EmployeeID Order By EffectiveDate Desc) EmployeeCurrentDesignation,

How To Put Only Changed Fields Into A New Table

Ha all again.
I have this issue:
I have 2 tables:
t1 (id,field1,field2,field3)
and t2 (id,field_name,field_value)

is possible with trigger to insert only changed fields on t1 to t2 like

(changing field1 on t1 with id 21 cause a new row in t2 with fields id=21,field_name="field1", field_value=field1.value)

i hope you understand what i look for.

Partof the database tracks membership using tables like this:PersonInfo-------------------PersonID (primary key)FirstNameLastNameetc..PeopleMemberships-------------------PPLMembershipIP (primary key)PersonIDMembershipTypeIDFeePaidMembershipTypes--------------------MembershipTypeID (primary key)MembershipYearStandardFeeMembershipDescription (varchar)Just because a person is in PersonInfo, doesn't mean they have anythingin PeopleMemberships (they can be in the databse for other reasons andnot have or have ever had a membership).Membership fees vary by year and type of membership and they want toretain a history of a person's memberships.What I'm looking to do here is write a query (a view in SQL Server)that will return the following InfoPersonID, MostRecentMembershipYear, FeePaidForThatMembership,DescriptionOfThatMembershipI'm thinking that I'd use max(MembershipYear), but that requires groupby for the other columns, so I'm getting all of the people'smemberships returned.I'm pretty sure this can be best done with a subquery, but I'm not surehow.Can someone please point me in the right direction or provide a samplethat I can learn from?Kindly,Ken

Instances And History In One Table

Jan 11, 2008

I have a database design question. There're lots of ways to rome they say, and I want to hear what you think of this way.

Government supplies wheel chairs (and thinks alike) to people who need them. They stay in possesion of the (local) government and are distrubuted by a company X.

So we have Tools (Wheelchairs) and Users (of wheel chairs). The life-cycle of a wheel chair is that more than one user while use it over time.

I want to keep track of which users used a instance of a wheelchair.

No there's a developer who likes to put this in one table. (the chair and it's user) in a way like this


UID, WheelChairId, UserId, OwnerId, SerialNumber, BeginDateTime, EndDateTime, SomeOtherColumns

The UID is unique, the WheelChairId is a GUID which is Unique per wheelchair, but can have mutliple records in the table with no overlap.

If one of the values of the columns is changed a new record is made with the same wheelchair and a new begin date (the closed record gets an Enddate). So history is made automaticaly. By using the right query's I can see what users uses the chair in what period of time. But also changed ownerships and other changes in Someother columns overtime.

Is this a good or a common practice? Why use it, or stay away from it?

Common Need: History Table

Jan 22, 2008

Hi there!

I'm working on an application designed like this:
There's a table "DailyTransations" (DT) containing daily transactions...
Then there's an archive table "TransationsArchive" (TA) with the exact same structure.

When a record is inserted in DT, it is also in TA (via a trigger) and the reporting is done against TA.
Now for performance issues, we delete from DT the records older than 2 days since they are not needed for processing.

First, what do you think of that implementation?

We thought about using partitions based on the transaction date and completely eliminate TA, but it seems once a record is assigned to a partition, it is not moved automatically...

What is the common solution for this need?

Thanks
Frantz

How To Check A Table Whether Data Is Changed Or Not..??

Jan 30, 2006

Hi..

I got 10 Tables with data in it for 100 Loans. The data can be Good and Bad .....

I had a Update Proc which Updates the 10 tables with the Good data what ever i pass...for this 100 Loans
Tha Proc will update the existing data in all tables whether it is Good or Bad Data.

when the updating is completed I want to know what are the Loans that were updated where there is a Bad Data in atleast one Field of the 10tables.

I don't want to check field by field in each table.... if there is a bad data and my proc updated with a Good Data i want to know that Loan.

Can any one has an idea on this,,,,

Thanks
Bob

How To Find Out If A Spesific Table Has Changed?

Feb 28, 2008

Hi,

I have a small question regard how to find out if a specific table has chanced.
Is there any (sql)function inside MSSQL2005 that I can use to find if a spesific table has changed? I have heard of timestamp, but I don't know if that will solve my problem? Is there any thing in the sys.tables that kan help me, just do a fast query and check if a table has changed?

I'm developing a web-application with AJAX.NET, and I have UpdatePanels with datalist. When the tables in the db gets big the application is henging for a sec or two when it receiving the data, and when the timer (refresh rate) is 2 min it is not good! So my plan is to check if the table has chanced since last transfer of data, and if it has it will download the data, if not do nothing.

How To Design The History Table To Be More Efficient?

Feb 8, 2007

I am running a website of crossword puzzle and Sudoku games. The website is designed to be:
There are 20-30 games onlines each day.
Every registered user could play and submit the game to win scores.
For each game, every registered user could get the score for ONLY one time. i.e., No score will be calculated if the user had finished the game before.
To avoid wasting time on a game finished before, user will be notified with hint message in the page when enter a already finished game.


The current solution is:
3 tables are designed for the functions mentioned above.
Table A: UserTable --storing usering information, userid
Table B: GameList --storing all the game information.
Related fields:
GameID primary key
FinshiedTimes recording how many times the game has been finished
Table C: FinishHistory --storing who and when finished the game
Related fields:
GameID ID of the game
UserID ID of the user
FinishedDate the time when the game was finshied

PS: Fields listed above are only related ones, not the complete structure.

Each time when user enters the game, the program will read Table B(GameList), listing all the available game and the times games have been finished. User could then choose a desired game to play.

When user clicks the link and enter a page showing the detail content of the game, the program will read Table C(FinishHistory) to check whether user has finished this game before. If yes, hint message will be shown in the page.

When user finishes the game and submit, the program will again read Table C(FinishHistory) to check whether user has finished this game before. If yes, hint message will be shown in the page. If no, user will get the score.

Existing Problems:
With the increase of game and users, the capacity of Table C(FinishHistory) grows rapidly. And each time when a game is loaded, the Table C will be loaded to check, and when a game is submitted, the Table C will be loaded to check again. So it is only a time question to find out Table C to become a bottleneck.

Does any one here have any good suggestions to change / re-invent a new structure or design to avoid this bottleneck?
