SQL Server 2012 :: How To Group Near Duplicate Records Under A New Common Field

Aug 26, 2015

I've inherited a table of members that has the following structure:

CREATE TABLE [dbo].[dimMember](
[dimMemberId] [int] IDENTITY(1,1) NOT NULL,
[dimSourceSystemId] [int] NOT NULL CONSTRAINT [DF_dimMember_dimSourceSystemId] DEFAULT ((-1)),
[MemberCode] [nvarchar](50) NOT NULL,
[FirstName] [nvarchar](250) NOT NULL,
[LastName] [nvarchar](250) NOT NULL,

[Code] ....

Based on the way the data loads into the table there's a possibility of some records being near duplicates of each other. For example, we can have a member that has records that have the same first name, last name, SSN, but different addresses, membercodes, subscribercode etc... This can happen in pretty much any variation thereof.

What I want to do, is add a new column and use that to group the similar records under based on comparing on several columns. By this I mean, if a member matches 4 of the 7 values below with another member, we would group these:

First Name (1st 3 characters)
Last Name
DOB
CurrentAddress1
MemberCode
SSN
SubscriberCode

I'm at a loss of how to structure the SQL to update the new column in the table.

Reporting Services :: Display Group Name Value Of Each Group In Column Header Outside The Group?

Sep 29, 2015

I have an SSRS 2012 table report with groups; each group is broken ie. one group for one page, and there are multiple groups in multiple pages.

'GroupName' column has multiple values - X,Y,Z,......

I need to group 'GroupName' with X,Y,Z,..... ie value X in page 1,value Y in page 2, value Z in page 3...

Now, I need to display another column (ABC) in this table report (outside the group column 'GroupName'); this outside column itself is another column header (not a group header) in the table (report) and it derives its name partly from the 'GroupName'  values:

Example:

Value X for GroupName in page 1 will mean, in page 1, column Name of ABC column must be ABC-X Value Y for GroupName in page 2 will mean, in page 2, column Name of ABC column must be ABC-Y Value Z for GroupName in page 3 will mean, in page 3, column Name of
ABC column must be ABC-Z

ie the column name of ABC (Clm ABC)  must be dynamic as per the GroupName values (X,Y,Z....)

Page1:

GroupName                 Clm ABC-X

X

Page2:

GroupName                 Clm ABC-Y

Y

Page3:

GroupName                 Clm ABC-Z

Z

I have been able to use First(ReportItems!GroupName.Value) in the Page Header to get GroupNames displayed in each page; I get X in page 1, Y in page 2, Z in page 3.....

However, when I use ReportItems (that refers to a group name) in the Report Body outside the group,

I get the following error:

Report item expressions can only refer to other report items within the same grouping scope or a containing grouping scope

I need to get the X, Y, Z ... in each page for the column ABC.

I have been able to use this - First(Fields!GroupName.Value); however, I get ABC-X, ABC-X, ABC-X in each of the pages for the ABC column, instead of ABC-X in page 1, ABC-Y in page 2, ABC-Z in page 3, ...

What Are Common Indexes?

Aug 14, 2005

I just inherited a Java application with a fairly complex data modelthat does not yet have any indexes except those on primary keys. It isstill in development and before I get to do any performance testing Iwant to put some default indexes on it. I realize that this a veryvague request but it's better than nothing so I want to start withthose that are generally a good idea and then tune those areas thatrequire more fine grained approach. By the way, I'm mostly a Javaprogrammer so please forgive my DB ignorance and I thank you for anyhelp.Since the full schema is quite large I will use a simple example (fullycited below my questions). Here is list of indexes that I think wouldbe a good idea. If anyone can add to it or comment on my questions Iwould appreciate it.1. Index on primary keys in all three tables. My understanding thatthis indexing happens automatically just by declaring that a column isa PK.ALTER TABLE employees ADD PRIMARY KEY (emp_id);ALTER TABLE employee_addresses ADD PRIMARY KEY (address_id);ALTER TABLE departments ADD PRIMARY KEY (dept_id);Question: Does index get created automatically because this is a PK?2. Index on foreign keys in the children tables to prevent deadlocksand lock escalations.CREATE INDEX fk_index ON employee_addresses (emp_id)3. Indexes on common queries on all three tables.CREATE INDEX common_query_idx on employees(last_name, first_name,position)CREATE INDEX common_query_idx on departments(last_name, first_name,position)CREATE INDEX common_query_idx on employee_addresses(street, city)Question: Given that the searches can be on any field separately andin any combination should I also put an index on each columnindividually or will the composite index take care of individualsearches as well? For example, will the above indexes be sufficientfor the following SELECT:SELECT e.last_name, e.first_name from employees e, departments d,employee_addresses ea, dept_employees de WHERE e.emp_id = de.emp_id ANDd.dept_id = de.dept_id AND ea.emp_id = e.emp_id AND e.position ='master chief' AND d.dept_name = 'galactic affairs' AND ea.city='LosAngeles'4. Unique index on the association table. Again this is accomplishedusing PKALTER TABLE dept_employees ADD PRIMARY KEY (dept_id, emp_id)Question: Is the index on (dept_id, emp_id) automatic because of PK?5. The association table has to go both ways and PK takes care only ofthe first half. Thus add an index to go the other way.create unique index dept_employee_idx on dept_employee(emp_id,dept_id)Question: should I use INDEX ORGANIZED TABLE?Question: should I have UNIQUE qualifier on the second index given thatPK already takes care of it?Thanks,Robert===== EXAMPLE ======1) An employee can be in many departments and a department can containmany employees.2) Common searches for employees are on last_name, first_name,position, department_name, department_location separately and in anycombination.3) There are common searches for departments that contain certainemployees e.g. find all departments containing John Smith.CREATE TABLE employees(emp_id INTEGER NOT NULL,last_name VARCHAR(50) NOT NULL,first_name VARCHAR(25) NOT NULL,position VARCHAR(10) NOT NULL);CREATE TABLE employee_addresses(address_id INTEGER NOT NULL,emp_id INTEGER NOT NULL,street VARCHAR(50) NOT NULL,city VARCHAR(25) NOT NULL,);CREATE TABLE departments(dept_id INTEGER NOT NULL,dept_name VARCHAR(50) NOT NULL,dept_location VARCHAR(25) NOT NULL,);CREATE TABLE dept_employees(dept_id INTEGER NOT NULL,emp_id INTEGER NOT NULL,);ALTER TABLE employee_addresses ADD FOREIGN KEY (emp_id) REFERENCESemployees(emp_id)ALTER TABLE dept_employees ADD FOREIGN KEY (emp_id) REFERENCESemployees(emp_id)ALTER TABLE dept_employees ADD FOREIGN KEY (dept_id) REFERENCESdepartments(dept_id)

Common Interview Question

May 11, 2006

In my experience of going through plenty of interviews, I have came across a question that I am reminded of by someone's signature.

The common question in this instance is:
What is the advantage of a cursor over a stored procedure? Vice Versa?

I could only, in my so few experiences, have answered that stored procedure consumes less system resources than a cursor. The advantage a cursor has is record by record examination and looping capabilities.

Needless to say that whenever asked those questions, I haven't landed the position. So I'm wondering, what is the more appropriate answer?

Select Common Data

Sep 21, 2007

Hi - I'm trying to construct a select statement from the following tables(see example)

_________________________________
|Customer | Product |Shop |
|----------|----------|---------|
|Customer1 | Milk |Dairy |
|Customer2 | Cream |Dairy |
|Customer3 | Milk |Dairy |
|Customer1 | Trainers |Sports|
|Customer2 | Football |Sports|
_________________________________

REQUIRED RESULT SET: Milk, Cream.

Basically I want to select all of the Products (no duplicates) where EVERY customer(1, 2 & 3) have bought a from a common shop type: i.e 'Trainers' and 'Football' should not be selected as Customer3 has not bought any goods from a sports store.

This is an example of a larger problem where there can be numerous products, customers and shops. Here's a DESCRIBE of the relevent columns in each of the tables:

CUSTOMER:
customerID

PRODUCT:
productID
customerID
shopID

SHOP:
shopID

This looks like it should be easy but my SQL isn't the best ;-)

I'd really appreciate any help you could give!!

Cheers!

Common Properties Design

Jan 14, 2008

I try to find the best design for a SQL Server 2005 database structure.

I have the following 'objects':

Facilities
Departments - 'dependents' of a Facility
Users

Addresses - each of the above can have none or more Addresses.

The basic tables design would be:
CREATE TABLE [dbo].[Facility](
[cFacilityID] [nvarchar](5) NOT NULL PRIMARY KEY CLUSTERED ,
[cFacilityName] [nvarchar](50) NOT NULL
)
GO
CREATE TABLE [dbo].[Department](
[cFacilityID] [nvarchar](5) NOT NULL FOREIGN KEY REFERENCES [dbo].[Facility] ([cFacilityID]) ON UPDATE CASCADE ON DELETE CASCADE,
[cDepartmentID] [nvarchar](3) NOT NULL,
[cDepartmentName] [nvarchar](50) NOT NULL,
PRIMARY KEY CLUSTERED ( [cFacilityID], [cDepartmentID])
)
GO
CREATE TABLE [dbo].[User](
[cUserID] [nvarchar](5) NOT NULL PRIMARY KEY CLUSTERED,
[cUserName] [nvarchar](50) NOT NULL
)
GO
CREATE TABLE [dbo].[Addresses](
[pkAddress] [int] IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED,
[cAddress] [nvarchar](255) NULL,
[cZip] [nvarchar](5) NULL,
[cEmail] [nvarchar](255) NULL
)
GO


The question regards the Addresses table:
How can I design the Addresses table(s) so I can enforce relational integrity and cascade update and delete for each Facility, Department and User tables?

I figured out the following options, but none achives my requirements:

1. An Address table for each 'object': FacilityAddress, DepartmentAddress, UserAddress with the corresponding foreign key in each Address table. This solution duplicates all the addresses fields (which are more than I showed in the example).

2. A common Addresses table with a discriminator field (1=Facility, 2=Department, 3=User). This doesn't allow me to enforce referential integrity with constraint, maybe only with triggers.

3. A common Addresses table with a foreign key for each 'object (fkFacility, fkDepartment, fkUser) allowing nulls. In this case, the 'dependence' between Facility and Department stops me to enforce cascade deletes/updates on both Facility and Department foreign key (circular...).

4. An intermediate (link) table between each 'object' and Addresses table with the foreign keys (Facility, Addresses). Again, no referential integrity.

So, is there a method to design such structure?

PS. Please keep in mind that this is just a simplified example (reduced at the key information) of my real structure.

Thanks,
Ioan

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

Is It Common To Have CPU Usage At 50% Constantly.

Jul 19, 2007

The comapny i work for has a server running the following.

Opteron 246x2

2 Gig memory

320 Gig Sata 2 drives

Windows 2003 Standard Edition

SQL Server 2005 Express Edition. The Free one.

There are approx 10 users that connect to the server.

There are two programs which seem to use sql server. Act 7.0 and service ceo.



When the computer is rebooted its at 0% for sqlserver.exe

Than when all connect it maxes it 50% and its steady there. Seems Service ceo affects it the most.

Told by comapny need to buy full blown sql server to resolve problem. But i dont think this is the problem.



Questions: Is it common for server to be at 50% all the time with sql server running?

And if its not is there a way to reduce the sql cpu usage.



I am new to sql server and have done alot of research and fixes. Ive unsitalled and reinstalled all sql instances and done the tweaks suggested. Any fresh ideas would be great thanks.

Problem Getting 5 Most Common Occurences

Feb 14, 2008

I need to get the 5 most common occurences from a table. Not really sure of the SQL statement I would use to do that. Would someone be kind enough to throw out a select statement that would do this? psuedo code would be fine, I just need to know the jest of how to do it. I originally thought Select Top 5 would work, but then I actually started thinking and realized it wasnt it. So now im stuck. Any help would be appreciated.

Thanks,

Common Image In Reports

Apr 17, 2007

I need to display the company logo on 100 odd reports that run from different folders on the report manager. Since the company logo has changed before and we had to change every report, I want the image stored on a server (with SSL on) and want the reports to point to the server. The server is going to be different in development and production environments.



When I try to add the image using "Image Wizard" I get the error "Invalid image.". The wizard wouldn't let me use a function to build the path based on the environment and select the image from the correct server. It doesn't accept anything that doesn't start with "http:" when I select "web" as the image source.



Please Help!!!

Datasets And SQL Injection

Oct 25, 2007

I have become a big fan of the datasets in Visual Studio 2005.  I usually create the SQL for each method in the table adapter; however, I am wondering if there is any 'built-in' functions in the C files for sql injection prevention?  I have read that using stored procedures is a good method for prevention.  Should I be using SP rather than SQL within my methods in the data table?

Large Datasets

Mar 27, 2008

Hi,

I have a table which has over 450,000 records in it, I have now split this into 4 so each table has around 100,000 records in it but I'm still having the problem of the data being returned really slowly.

What I need to do to this data is group it by a code and show the total for each code for every month of the year (this is currently based on one column and selecting the data accordingly). I have created views and put some indexes onto my table but the results are still being returned slowly. Does anyone have any suggestions of how I can speed this up?

Thanks

Datasets And Iff Statements

Sep 6, 2007



Hello experts,

I have a report with four different datasets that slice certain record by different days of the week. I can do the individual summing for each dataset by putting a , "datasetname" at in the expression. I also have 4 matrixes in the report that are grouped on certain transactions within each timeslice. My problem is that if I use the dataset name in the fields, the groups get ignored. Do I have to put the dataset name in each group expression? for example, here is my group expression...





Code Snippet
=iif(Left(Fields!TestName.Value,4)="VTAM","VTAM Logon",
iif(Left(Fields!TestName.Value,4)="CICS","VTAM Logon",
iif(Left(Fields!TestName.Value,4)="Shaw","SHAW Main Menu",
iif(Left(Fields!TestName.Value,7)="Inquiry","Inquiry Menu",
iif(Left(Fields!TestName.Value,6)="Search","Search Menu",
iif(Left(Fields!TestName.Value,6)="SEAX A","SEAX Auxiliary Search Menu",
iif(Left(Fields!TestName.Value,8)="SEAX - B","SEAX",
iif(Left(Fields!TestName.Value,4)="STLN","STLN","Other Value"))))))))






Not sure where I put the dataset name in this.

Thanks,
