Hi
I would like to is there any way we can store mathematical equations, that can be typed using equations 3.0, in sql server database as a column. What would be the datatype for the same.
Thanks
Hi,
I want to store complex mathematical expression in SQL database, and then display them on internet explorer, using asp or asp.net.
I'm really stuck as i don't know how i can store equations, and other symbols which are used to describe mathematical expressions.
For example how can I feed formula for area of a circle which is
Pi r square, and then this should appear on iexplorer as we read the formula in a book(i.e with symbol of pi and 2 raised), or
volume of a cone=4/3 pi r cube.
I'm not getting anywhere and have no hint what to do, Please, please help,
Thanks a million for the help

What is the equivalent in Transact SQL for VB.net ^ (Exponent Operator)
I have a following equation in VB.net
DotGain = ((1 - 10 ^(D0 - D50)) /(1 - 10 ^ (D0 - D100))) * 100 - 50
where D0, D50 and D100 are decimal variables
Working on creating a SQL UDF where @D0,@D50 and @D100 are transact sql decimal variables
DECLARE @DotGain decimal
DECLARE @D0 decimal
DECLARE @D50 decimal
DECLARE @D100 decimal
SET @D0 = 0.10
SET @D50 = 0.54
SET @D100 = 1.20
SELECT @DotGain = 1 - POWER(10,(@D0 - @D50)) / 1 - POWER(10,(@D0 - @D100)) * 100 - 50
but it is giving me different result in TSQL than VB2005
Can someone correct me?
Thanks in advance.
I've created a sql statement that retrieves number data from various table joins. The number data is then grouped according to various categories. What I need to do is to calculate the average of all the number data in a particular group. How do i go about this? Once calculated, the average needs to be displayed under the data.
For example, the report will list say five numbers (some sets may have more, it depends on how much data is returned based on the query), then under the five numbers, the average is given
2
4
3
6
0
Average: 5
What technique is best? Do I have to calculate the numbers in sql or do I need to configure the report to calculate the average? If so, how? Can someone show me step by step how to do averages for a set of data in the reporting services?
I am completely new to doing reports, I'm just a hobbyist, and I've only used databases to retrieve basic data, but not make manipulations for reports.
Any help will be appreciated.

Is it possible to use a stored procedure to fill the default value of a column when i'm building the db? i mean if i can use a stored procedure for the "colum property": "default value or bnding" if yes how can i do it?
View 2 Replies View RelatedHere is my objective:
As part of auditing of our application, I want to write the values of all column in one row out to an audit table both before and after an update to see what the changes were.
I know I can SELECT * FROM tableName FOR XML AUTO to generate a single XML 'column', but I cannot figure out how to capture that output and store it.
According to MS, you cannot use FOR XML in a subselect, or fill a TEXT variable with the results of such (which, IMHO really diminishes the usefulness).
I want to stream out the results of one entire row and store that in ONE column of an audit table. XML seems like the easiest way if not for this limitation.
A better way?
Thanks.

View 1 Replies View RelatedHello,
In my application, I have a master table that stores information about some other user tables. These other tables are all of different types, that is, the number and type of columns need not match across the user tables.
From the application perspective, logically each of these user tables is nothing but a column field within the master table.
I have seen references about "table" data type in SQL Server. It is possible to create a table that actually has a table data type as its field?
Thank you in advance for your help.

Order_ID
Order_amount
Order_Date
Order_Delivered
and the query is
select * from order where order_date = '2007-11-23' and 'Order_delivered='N'
I want the result to be stored in cache table either csv or xml

I am building three partitioned, clustered column store tables.I was researching whether it was faster to populate a staging table and swap it into the partitioned table or to directly insert into the partitioned table.The first partition for the three tables will have:
Table F: 50M rows, 6 columns wide, partitioned on a date column (1 date, 2 bigint keys, and two varchar columns)
Table D1: 50M rows, 150 columns wide, partitioned on a bigint
Table D2: 19M rows, 300 columns wide, partitioned on a bigint
If build the data that would go into partition 1 in a non partitioned column store, I get these table sizes:
Table F: 476 MB
Table D1: 6,800 MB
Table D2: 5,496 MB
If build the same data directly in the partitioned column store, my table sizes end up being:
Table F: 579 MB
Table D1: 6,800 MB
Table D2: 5,364 MB
That's a 20% difference on Table F, the narrow table.Looking at the row groups, I see 47 identical row groups in partition 1 and the unpartitioned table, but the average "size_in_bytes" is consistently 20% smaller in the unpartitioned table.
When we use Partition switch and load the data to a table, can we refresh the indexes for specific partition, so that we don't need to rebuild / refresh for complete is this possible ?

View 4 Replies View Relatedcan you have constraints as such [CreateBy] [nvarchar](30) NOT NULL DEFAULT (suser_sname()),on a table that has a column store index in SQL Server 2012,2014, or 2016?
View 3 Replies View RelatedI've been asked to look at using Clustered Columnstore indexes for one of my tables. The table contains about 5 million records with about 50 columns. The max field size is a NVarchar(MAX) with max field length currently of about 4k characters. It's only about a gigabyte's worth of data. The table is about 50% R/W operations. Currently, we have multiple indexes with no clustered index due to some performance issues that happened in the past. I've been attempting to determine if it's even really worth it to switch over. I feel that the table is still fairly small with minimal columns and don't believe there will be any noticeable improvement over traditional indexing.
View 3 Replies View RelatedI have a few flat files that will be retrieved from some SFTP server. One of the flat file will act as a terminal file where it will specify the total number of records expected in each other the flat file.
Data in the terminal.txt
FileName TotalRecords
File1 1000
File2 1500
File3 2000
So, before transforming the data from the flat file sources into the target destination, i wish to do a row count checking for each of the flat file source to make sure that the number of records in the flat file source is tally with the number of records specify in the terminal.txt file. I'm able to get the number of records in each of the flat file by using the RowCount component but don't know how to get the data out from the terminal.txt file in order to make a rowcount comparison.
Can any1 help me on this? Or is there any other way we can do to make sure that the flat file source is alright before proceeding with the data transformation task?
Thanks!
We are on SQL Server 2012 and I was wondering if you store the values in the columns with "date" or "datetime" datatype in MM/DD/YYYY format? Currently I am storing them as Varchar(10) using the Cast &Â Convert function to preserve "fomatting" but it would be great to do that in the date/ datetime datatype as well -- is that possible?
Note that this is not for a transnational table but for a data warehouse project. I have three fields in the date dimension each with it's own usage: INT (e.g. 20151016), DATE & VARCHAR.

I'd like to create a table that will store different order items. Several order items make up one single order. Order items can have 0 or more children (max depth will never be deeper than one). Order items can have up to 150 attributes/values. The way I think this should be done is using XML column instead of the EAV type of model. My table structure currently looks like this:
* child_order_item_id (PK)
* parent_order_item_id (FK to child_order_item_id)
* order_id (FK to Order table)
* product_id (FK to Product table)
* price
* attribute_XML
How my attribute_XML should look like or how to validate the xml.
We are storing changed data of tables into XML format for auditing purpose. The functionality is already achieved. We are using FOR XML Path clause to convert relational data of tables into XML format.
Now, a table is having column name with '(' . For example name of the column is, ColumnName(). In this case we can not convert into XML using For XML clause. Showing error as,
Column name 'columnName()' contains an invalid XML identifier as required by FOR XML; '(' (0x0028) is the first character at fault.
