SQL 2012 :: Store Attributes / Values In XML Column - Table Design
Oct 29, 2014
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.
I have been banging my head against the wall for TWO days. I have gone back and forth with a very patient guy on thescripts.com. You can see the ridiculous thread here
If you have time, at least peruse that so we don't go in circles. Anyway, if you guys can help me solve this, I will be forever grateful!!
Here is the "basic" problem:
Here is an example for TWO different entities in the database.
EntityID XmlFieldName Value 1 City Austin 1 State TX 1 Country US 2 CityName Los Angeles 2 StateCode CA 2 CountryCode US 2 Zip 111111
Here is how the two different results should be
where EntityID = 1 <Address City="Austin" State="TX" Country="US"/>
where EntityID = 2 <Address CityName="Los Angeles" StateCode="TX" CountryCode="US" Zip="111111"/>
Notice how the attribute names (City or CityName, State or StateCode, etc) are based off the XmlFieldName and I don't know in advance what the possible values will be? I also don't know how many attributes there will be, but they can be different per entity, depending on how they have set up an address in our application.
Another thing to note, is that I kind of have this working in an sproc using PIVOT and generating a table with the values that have the correct dynamic column names (you can see this on my other thread I posted above) but I REALLY need this to not use dynamic SQL (so can use it in a function) if possible and be able to be used in a select statement, whether it be a temp table as I would like to get a result set back that I can do a FOR XML RAW on. If this is confusing, it is because I am delerious. OR is there a way to return a table from an SPROC that has dynamic columns built?
I have created NONCLUSTERED index on table but my report is taking more time that's why i created columnstore NONCLUSTERED index on the same table but i have one query, if any table have row and column level index(same columns in index) . Which index query will consider.
I am looking to store the different forms and data in our database. We have several different forms and contains different information. I am looking for different approaches to model this table structure.
Also, I need to make sure the table structure will allow for new forms.
can 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?
i design SP for insert data in 2 tables i need to store list of array in one parameter to complete my query i try the table value but it`s not good for me because table value is readonly and i need to insert data with list of array .....
I apologize ahead of time for the long post...Background:Working on a CRM type custom application. The application is for anevent management company. The company will provide the application forother organizations to manage their own events. The events includeconferences, corp meetings, sales meetings, etc...An event planner will define what information is needed for an attendeeto register for an event. We will be providing a standard list ofattributes for the event planner to select from. This list includespersonal information (name, address, phone numbers), air travelinformation (preferred carriers, departure airports, etc...), hotelinformation, etc...we've included all of the information available tous from the business's previous experience. As far as the databasegoes, all of the standard information given to use will be normalized.The problem is each event may have unique information that needs to becollected that is not part of the standard list of attributes. Forexample, if McBurgers is planning an event, the event planner may wantto collect an attendee's McBurger employee code.Depending on the uniqueness of the event, there may be up to 200 uniqueattributes defined for it. This number comes from researching eventsplanned in the last 5 years. The number of attendees for an event rangefrom 100 to 10,000. The company expects about 3000 events per year.Database DesignI've done a fair amount of research and found a couple of options tomeet our requirements, more specifically the need for event planners todefine custom attributes for an event.1-)DynamicColumns:Add an Event specific custom attributes table. The table would looksomething like this:Event_McBurger05AttendeeID | McBurgerEmployeeCode | HiredDate | SomeOtherAttribute-Join Bytes! | AxEt356 | 01/01/2004 | Other val 22-)EAV:Add an EAV (entity, attribute, value) table. The table would looksomething like this:Event_AttributesEventCode | AttendeeID | Attribute | Value-McBurger05 | Join Bytes! | McBurgerEmployeeCode | AxEt356McBurger05 | Join Bytes! | HiredDate | 01/01/2004McBurger05 | Join Bytes! | SomeOtherAttribute | Other val 2The Value attribute would be a character (probably varchar) datatype.3-)Stronger Typed EAVHave an EAV table for each data type. The tables would look somethinglike this:Event_CharAttributesEventCode | AttendeeID | Attribute | CharValue-McBurger05 | Join Bytes! | McBurgerEmployeeCode | AxEt356McBurger05 | Join Bytes! | SomeOtherAttribute | Other val 2Event_DateAttributesEventCode | AttendeeID | Attribute | CharValue-McBurger05 | Join Bytes! | HiredDate | 01/01/2004There would be one Event_[DataType]Attribute table for each of thedatatypes allowed.Pros/Cons1-)DynamicColumnsPros:-Data integrity can be enforced-Simpler queries for reporting-Clearer data model for understanding data storedCons:-Row size limitation of 8k must be managed (probably need to addanother table if run out of room.-Stored procedures for CRUD operations would need to dynamicallycreated ORNeed to use dynamic SQL on the database or application.-Adding/Removing columns on the fly can be very error prone2-)EAVPros-Static CRUD stored procsCons-No data integrity-Complex queries for reporting-Worse performance than option 1.-Table can get BIG...fast.3-)Stronger Typed EAVPros-Static CRUD stored procs-Better data type integrity than EAVCons-Complex queries for reporting-Worse performance than option 1-Table can get BIG...fast.If you are still reading this...thank you!The Questions:-Are there other options other than the 3 described above? Or are thesepretty much it with slight variants.-Does anyone see any missing Pros/Cons for any of the options thatshould be considered?-Is there a "preferred" method for what I am trying to do?I suspect this will come down to the lesser of three devils. Justtrying to figure out which of the three it is.We have prototyped the three options and are leaning towards option 1and 3.Any comments/suggestions are appreciated.Thx
*CV to CVEducation is 1 to Many. CVEducation(CVID) is a foreign key
This is my table named - Level
*LevelID is stored in CVEducation. So, we can know - This education is Diploma or Degree or Masters or so on
This is my table named - StudyField
*StudyFieldID is stored in CVEducation. Som we can know - What kind of Education they have.
This is the example of Job Vacancy 1
1- Need Diploma in Chemistry OR Degree in Chemistry.
2- CGPA at least - 2.5
*May be need to store 2 rows with each CGPA
This is the example of Job Vacancy 2
1- Need Diploma in Commerce OR Diploma in Economics OR Degree in Biology
2- CGPA at least - 2.8
*May be need to store 3 rows with each CGPA
How to design my table to store Job Vacancy Minimal Requirement? I know, there's some cases we cannot computerized. But, at least some of Job Vacancy Requirement we can computerized.
We have a table with 10 columns each column is of datatype int and can accept nulls, when I do a save is it better to have 0 inserted in to the column or just insert null?
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 ?
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.
I just joined a bank related IT department where the existing IT team is already working on creating a new application since a year now and designed database on SQL Server 2012, the amount (currency related) column's datatype found different in tables some where it is decimal and somewhere found different. I want to suggest them Money datatype to choose where we are dealing with currency related columns. My question is, is that correct to choose Money datatype or should I ignore this?
We have a typical issue with Column Store Index, we have a procedure which does 2 activities - Switch & Reverse Switch
Switch: 1. Fetch the Partitions needed to be switched 2. Switch the data from Main Table to Switch table 2. Disable the Column store on Switch table
SSIS Package: 3. Load data to Switch (Insert / Update)
Reverse Switch: 4. Enable the Switch 5. Switch back the data from Switch table to Main table
Issue: Some time the Column store is not getting disabled, and the package fails complaining try disabling the Column store index and try loading data.
If we re-run the procedure, the column store gets disabled.
HI I have a problem related Store Procedure, that i am trying to extact a value from Database (Like FirstName,LastName,Email Address) through Store Procedure and Display it in the DropDownList(Like: FirstName LastName ,(xyz@xyz.com)) , and this is working correctly. Now i try to check the value at the same time if it is NULL value in the Database then pass EmptyString to the DropDownList Like ("" "" ,(xyz@xyz.com)) how i can do that in the store procedure. Comments will be appreciated.
I need to replace all the "User Friendly Names" with "System Names" in the calculations, i.e., I need "Sales Units" to be replaced with "cSalesUnits", "AUR" replaced with "cAUR", "Comp Sales Units" with "cCompSalesUnits", and "Comp AUR" with "cCompAUR". (It isn't always as easy as removing spaces and added 'c' to the beginning of the string...)
I have created a CTE of all the "Look-up" values, and have tried all kinds of joins, and other functions to achieve this, but so far nothing has quite worked.
How can I accomplish this?
Here is some SQL for set up. There are over 500 formulas that need updating with over 400 different "look up" possibilities, so hard coding something isn't really an option.
In return I need to check column Status for whenever the value has changed and need to store that in my table. If there are two records for which value in column Status is same, I need to pick only one of the records and that being the earliest of them and therefore the Date field is mentioned in my table . My output should be something like below.
I have several reports that are looking for a code within a certain set of codes or ranges. The specific list of codes to be including is determined by the end user. Currently my "IN" statement can be a hundred lines, listing several ranges, lists of specific codes, etc. I am constantly getting asked what codes does it include, is this code included, etc. Sometimes they'll give me a printed 10 page list of codes and want me to compare to what I have included in the report. Not ideal in the slightest.
What I'd like to do is have a table or a file of some kind somewhere where the end user can view the codes contained, add new ones, and delete ones they no longer want. Then I'd like to be able to just reference that file in my IN statement. Leaving the responsibility of listing the correct codes on them.
While writing store procedure in db most of Time i will Use common Table to write select queries for selecting more than seven table whether it reduce speed performance or it won't
I have a requirement of table partitioning. we have 10 years of data on a table which is 30 billion up rows on 2005 server we are upgrading it to 2014. we have to keep 7 years of data. there is no keys on table or date column. since its a huge amount of data and many users its slow down the process speed. we are thinking to do partition on 7 years for Quarterly based. but as i said there is no date column on table we have to use reference table to get date. is there a way i can do the partitioning with out adding date column on table? also does partition will make query faster?
I have think three ways to do it. 1. leave as it is. 2. 7 years partition on one server 3. 3 years partition on server1 and 4 years partition on server2 (for 4 years is snapshot better?)
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?
I need to round UP values but they should never be rounded down, below is my expected output in RoundVal column.
SELECT 89 AS Val, 100 AS RoundVal UNION ALL SELECT 329, 1000 UNION ALL SELECT 6329, 10000 UNION ALL SELECT 43299, 100000 UNION ALL SELECT 155329, 1000000
I have a field in a table that contains a different formula (varchar(1000)) for each record. It's along the lines of something like this, although each formula is different: ([ColumnA] - [ColumnB])/([ColumnC] - [ColumnD]). I plug that into a dynamic SQL statement so that it can get executed in a select statement.
Due to the variations of the formulas, checking for Divide by Zero, etc, we want to move this to a .NET method. We'd like to replace "ColumnA" and "ColumnB", etc., with the actual values so that we're passing something like (5-3)/(6-2). I haven't been able to figure out a way to do this without actually executing it. We don't want to pass the solution, but the equation filled with the actual values rather than the column names.
I am working in SQL Server Master Data Services Version 11.0.5058.0 (SP 2).
I have been asked to group all the financial attributes together. When I move one of the attributes up using the arrows, it works good jumping over one attribute at a time. Then I reach a section of attributes where it leap frogs over 24 attributes.
It appears these 24 attributes are in a subgroup but there are no attribute groups and I removed the subscription view from the entity. If I move one of the 24 attributes in the group, it moves it outside of the 24 attributes.
This is under leaf member attributes. There are no collection or consolidated groups.
I have an ordering database with several tables that store data of orders belonging to a wide variety of clients. There is a generic report that I need to run which outputs the same data elements. However the criteria to select these orders will vary widely between each client. For e.g.
i) for client# 1 it could be all orders that are still open after 30 days of placing an order
iii) for client# 3 it could be a combination of different things (all orders in West Region that are in hold status for more than 10 days + all orders in Eastern Region that are in shipping and are expected to be delivered in the next 2 days + all completed orders for the rest of the regions).
( OrderRegion = 'West' AND OrderStatus = 'Hold' AND GetDate() - OrderHoldDate >= 10
[code].....
I want to have a stored procedure that selects all data and dynamically attach the where condition at the end for filtering. This way I wouldn't have to worry about any additions/changes that are made to the selection criteria. I can build an interface for admins who can use the UI to maintain the selection criteria and not worry about any code changes to accommodate it. I would like to design a table that holds this criteria. At this point in time, I am thinking of using key value pairs (Column Name, Column Value) but I am not sure how to implement multiple logical operators.
How do I SELECT multiple nodes with same name but different attributes. For example, I would need to SELECT NM1.03.1 from <NM1> node. How do I specify which one I want to SELECT? What if I want to SELECT them all? What if I only want two of them?
With the data example below I am trying to consolidate the duplicate rows by flattening the dealer and billcode, or putting those values in each of the columns instead of creating separate rows...

I'm using a DW from Northwind database to build a cube to do some analitical taks. I already create the cube and now I am "cleaning" the dimensions. I'm having some difficults to understand the logical off this part. The reason is that When I create the Data Source View, I only import the Foreign Keys that connect the Dimensions to Fact_Table. I have to drag the attributes of Dimension from Data Source View to the tab attributes?
Imagine this:
I have the following dimension:
Dim_Customer: Customer_ID Name_Customer Job_Function Date_of_Birth Contact Address City Country
When I create the cube only Customer_ID appears in attributes tab, it's normal?
One more question:
I don't want to create a hierarchy like:
Customer ID -> Name_Customer Customer ID -> Date_of_Birth Customer ID -> Address Customer ID -> City Customer ID -> Country
My idea is to create the following hierarchy:
Name_Customer -> Date_of_Birth -> Address -> City -> Country
But the first hierarchy that I show is always appears to me. Do you know what is happens?
