I would like to do data mining. But my data is not useful.
my table structure is something like:
date customerid age residence prosubsclassid productid
----------------------------------------------------------------------------
21.11.2001 123232323 a b 2099 23232322
amount asset sales
------------------------
4 34 56
Now I have to show the data in this way:
prosubsclassid 130207 130208 130209
------ ------ ------
1413232 1 3 1
3435545 2 1 2
3534344 3 1 sum(amount)
Column(customerid)
I want to convert to tabular form in my data.
There is no automatic way to do this. There are support for pivot in SQL server, but the columns still needs to be specified.
Depending on if you want to have a text report or a table with dynamic columns I would group the data per date and prosubsclassid and then using a cursor to build the data.
If you want a dynaic table build a dynamic sql query based on the grouped data and run Exec.
If you want text report, just concatenate the string data the way you want per line into
a temp table with one textcolumn and when you are done, select the table.

I am trying to make a table that shows changes in a database with the following format:
TableName
ColumnName
OldValue
NewValue
RowID
Company
CompName
ABC
XYZ
1
Company
Address
123
456
1
Company
CompName

This is all in Microsoft SQL Server, and want to try and use the system tables to connect with the data using triggers as the data is updated (using Magic Tables to capture the old/new value as it is changed).
I just don't know how to connect the table and column information with the row data to get it to display in this format.
So far I have been able to find the system tables and get them to show their updates, and the regular tables with their updates, but have not had success in figuring out how to connect them together.
Hello I don't know how to do changes of my MS SQL DB to integrate it to work with new software.
The case is related with software limitations.
Our old software can write, read and work with MS SQL DB with multiple tables but the new software understand only from one table or one view table.
My question is how can I edit my MS SQL DB form 20 tables to do it to be one DB with one table with all data from 20 tables and columns without data lost?
And one last question is true about View Tables in MS SQL that they are read only for applications and software?
Why is it not a good idea to put data from all your 20 tables into one table ?
I will try to explain with an example, since I do not know your database I just think of some tables here
suppose you have a table Clients
ClientID Name Street City
1 John ChuchStreet Denver
2 Anna FlowerStreet Boston
and a table Products
ProductID Name Price
1 Mouse 10
2 Keyboard 30
3 Usb Cable 10
and table Orders
OrderID OrderNumber CLientID TotalAmount
1 123 1 10
2 345 1 20
3 678 2 30
and finally table OrderDetail
OrderDetailID OrderID ProductID Quantity
1 1 1 1
2 2 1 1
3 2 3 1
4 3 2 1
Now to put this into one table, you could do this
ID ClientName ClientStreet ClientCity OrderNumber TotalAmount ProductName ProductPrice ProductQuantity
1 John ChurchStreet Denver 123 10 Mouse 10 1
1 John ChurchStreet Denver 345 20 Mouse 10 1
2 John ChurchStreet Denver 345 20 Usb Cable 10 1
3 Anna FlowerStreet Boston 678 30 Keyboard 30 1
Now you can already see the redundancy,
you need to repeat the address of each customer, time and time again in your table
you need to repeat the ordernumber and total amount time and time again
you need to repeat the productname and price time and time again
Now suppose that John moves to another address, now you have to search for John in every row in the table, and adjust the address
Now suppose a productname changes, again you have to search all rows and update
That is lots of work, very inefficient, and guaranteed to go wrong at some point
Now I only used 4 tables in this example, can you image what will happen if you would merge 20 tables into 1 ?
And the redundancy is not your only problem, what if you want to look at a client, what row should you use ?
What if you want to look at an order, what row should you use ?
What if you want to look at a product, what row should you use ?
In this one table design, you cannot identify a single row for customer, or order anymore. That is because each row contains everyting, there is no distinct row anymore for a customer, or a product, or an order...
Merging all tables into one big table is simply not possible to maintain
Hi thank you for your answers!
I am trying to integrate old ms sql db to new IDFLOW Software.
This software understand from ms sql db but only from one table but my old db contains 18 tables....
IDFLOW understand from views, but it is not good to work with views, they are okay for card design in IDFLOW, but views are not okay to write new data in db from IDFLOW interface , because in views it is not possible to write new data in db!
And now I started to think to create one db with one table with all columns, and I completed it successfully!
Now in my sql server I am with two db, old db and new db.
Now I don't know how to export data from old db and import it to new db?
I am talking about export column2 from table1 from db1 and import it in column2 from table1 from db2 ....
and so and so ........... column2 from table2 from db1 and import it in column3 from table1 from db2 ............
and so and so .... column 5 from table18 from db1 and import it in column10 form table1 from db2.
Is it possible to do that?
Okay, but IDFLOW works only with one table...
And I asked Jolly and they say utilize your DB for one table.
IDFLOW is a software for ID CARDS .
I think it is possible to use one db with one table and all columns for employee information.
The goal is.. in IDFLOW enter all data for new employee, when you enter data from IDFLOW interface they go into MS SQL DB and all fields from DB are in card design configured, and when you select records for one employee from IDFLOW interface (from db) you can print ID CARD with all data for employee.
The question is how to migrate old records from old db in new.
It is not big database, it is only 6 GB from 2006.
And we use it only for printing id cards.
I am trying to rank records in power pivot table using DAX as below in MSSQL analysis service tabular model.
Example details:
I have a shop sales detail in table.
e.g.
ShopNo date sales
-----------------
1 2014-11-09 120
1 2014-11-09 130
2 2014-11-10 130
2 2014-11-10 135
In pivot table data is analyzed month and year wise.
I want to see result like
ShopNo sales rank
-----------------
2 265 1
3 250 2
Any solution is there to display statewise population automatically.
Thanks
You should be able to achieve the ranking quite easily with PowerPivot using this formula:
RankShop:=RANKX(ALL(SalesTable[ShopNo]), [Sum of sales],,,Dense)
With SalesTable being your shops sales table. If you then create a pivot table - drag ShopNo onto Rows and add new Measure (Excel 2010, in 2013 it's Calculated Field). The resulting table could then look like this:
To find out more about RANK function, I suggest this article.
In order to hide the rank value in Grand Total row, add a simple condition that puts blank values in case of grandtotals:
=IF(HASONEVALUE(SalesTable[ShopNo]), [RankShop], BLANK())
Hope this helps.
Inserting one table's complete column data to a particular column in another table in SQL SERVER
I have two tables i.e AuditCalendar, ScheduleAudit
Audit Calendar has two columns Taskid, TaskTypeId
Schedule Audit has two columns Scheduleid, Taskid
Audit Calendar looks like this
Taskid (Auto increment) TaskTypeId
-------------------------------------
1 1
2 2
3 3
4 1
5 1
But I want Taskid column data from Audit Calendar table based on TaskTypeId .Columns
After completion of query, the ScheduleAudit table should look like this
Scheuleid (AutoIncrement) Taskid
-------------------------------------
1 1
2 1
3 1
I have to run this query seems to look like a error
Subquery returns more than one value
Query is:
INSERT INTO ScheduleAudit(TaskId)
VALUES ((SELECT TaskId FROM AuditCalendar Where TaskTypeId = 1))
Please can you suggest how I can do this approach I am new to SQL Server but someone says that use cursors.... I am really confused last 1 week on words. And also search google but not get it now...Please can you give me any one valuable suggestions.
insert ... values is supposed to insert a single row. So what you have in the parentheses is supposed to produce a single row, or else it would fail.
There's no need to use insert ... values, when you can use insert ... select:
INSERT INTO ScheduleAudit(TaskId)
SELECT TaskId FROM AuditCalendar Where TaskTypeId=1
...however, that would produce
1 1
2 4
3 5
I'm not sure I understand the logic behind producing your example output.
I have the following table ,
Database Table:
BatchID BatchName Chemical Value
----------------------------------------------
BI-1 BN-1 CH-1 1
BI-2 BN-2 CH-2 2
----------------------------------------------
I need to display the following table.
BI-1 BI-2
BN-1 BN-2
-----------------------------------------
CH-1 1 null
------------------------------------------
CH-2 null 2
------------------------------------------
Here BI-1,BN-1 are two rows in a single columns i need to display chemical value as row of that.Could Please help me to solve this problem.
I tried it in Pivot table but i unable to get this.
So is there any chance in Reporting Server MDX.
First, you need to create a cube with Analysis Services (MDX only works against multidimensional data sources)
Then, assuming you have a cube "MYCUBE" with "Batch" and "Chemical" dimensions and a "Value" measure, the query would be something like this (of course, you could select just the members you need instead of all the members in the dimensions):
SELECT
{[Batch].members * [Measures].[Value]} on columns,
{[Chemical].members} on rows
FROM [MYCUBE]
