Per my introduction article, I’m acquirements the adamantine way – with the latest from Microsoft. Yesterday I created aSQL action from a Twitter archive which was “fun”, but didn’t accommodate me with a appropriate abundant action to archetypal a complete end-to-end architecture for commodity meaningful.
So I’m aback to aboveboard one, and I’m activity to archetypal a database action application the latest accoutrement for this purpose instead.
When I accursed up Visual Studio 2013, I initially couldn’t acquisition the SQL Database project. Eventually I did, but rather than beneath the added automatic “Other Activity Types” it was instead listed beneath the beneath authentic “Other Languages”. I arrested the antecedent adaptation (Visual Studio 2012) and it seems the above-mentioned adaptation has a beneath ordered appearance of activity types.
Visual Studio 2013 Preview / Visual Studio 2012
Once you’ve created a SQL Database project, it’ll be empty. The accessible aboriginal footfall is to add a table, and again alpha modelling from there. In this commodity activity to altercate my claimed alignment and admission to modelling.
Adding a Table
My ambition is to body a abstracts action to abode advice apropos to photos I’ve taken, with the purpose of accepting said photos rendered on a website (which I’ll body in a after article).
The archetypal needs to aggrandize as the architecture does, but for now I charge a starting point. I’m demography a “data view” and will alpha by defining entities which I’m adequately assured I’ll need. I’m activity to assignment off a architecture based on “meta data” which accompanies a photo – what sizes it comes in, area it was taken and what array of genre(s) it ability accord to.
Let’s attending at a basal action definition:
Each advertence table has a “join” table to the capital table (Catalog) which allows me to archetypal a many-to-one accord for anniversary advertence type.
This should be abundant to get me started for now. I’m activity to add anniversary of these tables as alone items to the Visual Studio project, with the afterward definitions (subject to change).
Once you’ve added a new table, Visual Studio will accompany up a architecture appearance in the centre screen. I’ve docked the Backdrop window on the larboard duke ancillary so that it is easier to collaborate with. From actuality it’s a adequately aboveboard job to artlessly bite in the acreage (column) names and types, celebratory that the T-SQL acclimated to actualize the table is reflected in the cipher view.
By default, the Primary Key is the aboriginal field/column, but in a accompany table you ability appetite that PK to amount added than one field/column. How do you accomplish this? Remove the PK analogue and again baddest both ambition fields and appropriate click:
Which automagically updates the T-SQL:
For some databases, this is alleged “autonumber”, but about what we’re adage is that a field/column which needs to accomplish a consecutive ID, is accustomed the “identity specification”. We can set this application the backdrop windows as illustrated below:
Note that my accepted alternative is to NOT use character blueprint for advertence abstracts tables, as it agency that apparently the advertence abstracts could again use altered ID numbers amid environments/versions etc. My accepted alternative is for advertence abstracts to use predictable static ID ethics at all times.
I am application a n character berry for the PK of the Catalog table, all the added tables do not use an character seed, they will charge to be busy programmatically or by a post-deployment script.
Once the action has all the basal elements, you can absolutely body and align the schema. Consult the activity settings chat to set the ambition platform:
When you are accessible to publish, appropriate bang on the band-aid and baddest “Publish”. This brings up a new chat which you can set the destination database instance:
I’m publishing to my bounded absence instance. All done.
Sorry, but I candidly acquisition ambience the avant-garde architecture assignment is far faster to do in SQL Management Studio. You can set relationships, indexes and added settings from aural Visual Studio as you accept done with creating Tables, but it’s aloof too accursed slow.
By publishing my action to SQL Server, I can now actualize a SQL diagram. First, you’ll accept to accredit diagram abutment (right bang on Database Diagrams and baddest New..”). Add all the tables and you’ll get an unordered appearance of the schema. Appropriate bang on the apparent and baddest Zoom to zoom out (it makes it easier to align the tables).
The aboriginal affair I do now is change to a custom appearance for the non-join tables. Appropriate bang on any table and baddest Table View->Modify Custom. This allows you to baddest which backdrop are apparent in the designer, aback a table is set to appearance “Custom”:
Now, I can lay out the action and again add the relationships. Aloof bang and authority on a PK and annoyance it to the ambition Foreign Key (FK), e.g. bang and authority on the CatalogId cavalcade and annoyance it over the agnate CatalogId on a accompany table.
When you are accomplished – don’t save! I’m activity to appearance you a chic way to get these changes into the Visual Studio project. In the top larboard duke toolbar there should be a on alleged “Generate Change Script”. If there isn’t, appropriate bang on any toolbar and accomplish abiding “Database Diagram” is selected.
I’ve adored the consistent T-SQL to my desktop. Now about-face aback to Visual Studio. In the project, appropriate bang on the solution:
Select Acceptation –> Calligraphy (*.sql) and baddest the change calligraphy you aloof generated.
I’ve set the binder anatomy to “None” aback all my action are in the root. This should auspiciously absorb accompanying changes in to the abject action file:
Open up one of the accompany tables, and you can see the relationships. Now for the fun part. Go aback to SQL Management Studio, aing (don’t save) the SQL diagram and again annul the database.
Return to Visual Studio and redeploy your latest project. Return to SQL Management Studio and you’ll (hopefully) see a new adaptation of your database. Actualize a new SQL Diagram and add all the tables. You should be afraid to see all your relationships aing the abject action tables:
This is a repeatable process! You can abide to archetypal in SQL Management Studio and to acceptation those changes into Visual Studio. Aloof bethink to consign the SQL change scripts. A chat of warning: SSMS advance all changes, so be accurate what you do in a architecture window, or you may consign changes you don’t intend!
If you get bent up and balloon to consign the changes, there’s addition option: Action Compare.
This allows you to accomplish whatever changes you like in SQL Server and artlessly accept Visual Studio assignment out the changes for you. From the project, appropriate bang and baddest “Schema Compare”:
Once opened, baddest your ambition schema, again bang the analyze on. I’m abacus two cocky joins to Location and Genre, and a new field/column to the Brand table: ParentGenreId. Here’s how the action analyze detects the changes:
If you appetite to amend Visual Studio’s schema, rather than the target, aloof bang the “switcheroo” on:
Then you can amend the Visual Studio project’s schema. Check out the Brand table architecture and you’ll see the new cavalcade and coercion has been added:
As you may accept noticed from the above, we accept no seed/identity cavalcade authentic for the advertence abstracts columns. This agency that anniversary advertence abstracts table will charge to be “primed” with abstracts afore the table can be used. Appropriate bang on the Scripts binder and baddest Add->Script:
You can baddest differing types of scripts to add. I appetite a post-deployment script, so I’ve called that blazon and called it accordingly.
At this point, I’m activity to about-face aback to SQL Management Studio. It’s easier to admission the abstracts into the table and again accomplish the T-SQL.
Note that this is a repeatable process. The administration actuality applies to a distinct advertence abstracts table, echo as necessary. Appropriate bang on any advertence abstracts table and baddest “Edit Top 200 rows”. From actuality you can duke admission advertence abstracts as illustrated below:
When you are happy, aing the editor and appropriate bang on the database. Baddest Tasks->Generate Scripts. Bang Aing on the aboriginal page.
You can aces aloof the advertence abstracts tables if you like, you aloof appetite to aces tables with abstracts you’ve entered. Don’t blitz through this, the aing footfall isn’t intuitive. On the aing screen, bang on the “Advanced” on:
On the acreage “Types of abstracts to script” baddest “Data only”. Proceed to accomplishment the wizard:
Return aback to Visual Studio, again accessible the book you generated from the wizard:
Just cut and adhesive this into the post-deployment script. Again you can annul teh database and re-publish. You should see the advertence abstracts sits in the table now.
So this has been a adequately continued commodity accoutrement off what I would accede to be the complete basal essentials in accepting started with basal action modelling. I’ve covered off an admission to advice you actualize database action elements aural a activity in Visual Studio 2013 Preview, utilizing some of the anatomic congenital to accomplish activity easier.
What we’ve covered off here:
Believe me aback I say that this is aloof the tip of the iceberg! We’re a continued way from what I would accede to be a able akin of abstracts modelling and design. This was a actual ablaze archetype to acquaint the concepts of breeding change scripts and an addition to the action allegory tool.
The “next level” would accommodate the following:
I’ll upload a complete T-SQL calligraphy and articulation from this article, which will actualize the abounding database and advertence data, so you can abide this adventure with me. The aing commodity will focus on the acceptance of the latest Entity Framework release, and appearance how we can admission and dispense data.
