DATABASE DEVELOPMENTThe Developer’s experience

17/11/2012 | 5 |

Database Development

Often not integrated into application life cycle management and processes

What is a database development experience?

Install SSMS into developer machine…. It’s an «admin» tool Outside Visual Studio (it’s Visual Studio yes)

Third party tools… What does »deployment» means?

IMPERATIVE DATABASE DEVELOPMENT

The premise

17/11/2012 | SQL Saturday #176 – Pordenone, Italy7 |

Database Development Challenges

Databases are inherently stateful Focus is on ALTER instead of CREATE Dependencies complicate scripts Errors are often found only when scripts are

executed

Synchronizing application and database versions

Targeting different SQL Server and SQL Azure versions

Simple Schema Versioning Example

-- version 1CREATE TABLE dbo.Speakers( SpeakerId INT NOT NULL, FirstName NVARCHAR(64) NOT NULL, LastName NVARCHAR(64) NOT NULL,

-- version 2ALTER TABLE dbo.SpeakersWITH CHECK ADD CONSTRAINT Speaker_PK

-- version 3ALTER TABLE dbo.SpeakersWITH CHECK ADD CONSTRAINT Speaker_PK UNIQUE (LastName, FirstName)

Revision HistoryV 1 V 2 V 3

Imperative

Imperative scripts hard codes knowledge about: The state of the target system:

Presence of objects, dependencies, unbinding, rebinding Required ordering of operations

Cumulative changes need to be serialized v1v2v3v4v5 instead of v1v4v5

Validating the end-result against expected end-state is hard No easy way to compare expected vs. actual

Batching or separating multiple changes

There are third party tools

Imperative Versioning

-- version 1 Add table dbo.Auction IF OBJECT_ID (N'dbo.Auction', N'U') IS NULL BEGIN

CREATE TABLE dbo.Auction (` id INT NOT NULL, name VARCHAR(25) NOT NULL, start DATETIME NULL, len INT NULL )

END -- version 2 Add PK Au_PK IF NOT EXISTS (SELECT * FROM sys.key_constraints WHERE name = 'Au_PK' AND type = 'PK') BEGIN

ALTER TABLE Auction WITH CHECK ADD CONSTRAINT Au_PK PRIMARY KEY (id)

END -- version 3 Add UC Au_SK IF NOT EXISTS (SELECT * FROM sys.key_constraints WHERE name = 'Au_SK' AND type = ‘UQ') BEGIN

ALTER TABLE Auction WITH CHECK ADD CONSTRAINT Au_SK UNIQUE (name) END

Missing/Manual

Object Dependencies Intercept errors before deployment Don’t loose data Sync DB Managing different versions

DECLARATIVE DATABASE DEVELOPMENT

The foundation

Declarative

Define what you want in the form of a model Think about a table without thinking about the

specific SQL

Fill the model using a DSL (domain specific language) T-SQL

Use the model as the starting point “blueprint” for all operations

Declarative Versioning

-- version 1CREATE TABLE dbo.Auction( id INT NOT NULL, name VARCHAR(25) NOT NULL, start DATETIME NULL, len INT NULL)

-- version 2CREATE TABLE dbo.Auction( id INT NOT NULL PRIMARY KEY, name VARCHAR(25) NOT NULL, start DATETIME NULL, len INT NULL)

-- version 3CREATE TABLE dbo.Auction( id INT NOT NULL PRIMARY KEY, name VARCHAR(25) NOT NULL UNIQUE, start DATETIME NULL, len INT NULL)

Revision HistoryV 1 V 2 V 3

Model as the starting point “blueprint”

Deployment/publish, start by comparing the current state of the target with the required state (blueprint)

Use the resulting difference knowledge to programmatically generate an deployment plan

Use plan to create sequence of (SQL) statements required to make the target state become like the blueprint state

SQL Server Object Explorer (SSOX)

The SQL Server navigation tool window Modeled after the SSMS Object Explorer Server scoped vs. Server Explorer which is database scoped Launch point for T-SQL Editor, Debugger, Object Execution,

Designers, …

Supports connecting directly to SQL Server SQL Server {2005, 2008, 2008R2, 2012} and SQL Azure

Supports connecting directly to a (contained) database

Constructs a partial model in the background and under the covers

Supports: Cascading Drops and Renames Drift detection

Automatically updates the tree/source as changes occur on the server

T-SQL Editor/Debugger/IntelliSense

T-SQL IntelliSense SQL Server 2005+ incl. SQL Azure

Result to Grid | Text | File Execution modes

Execute Execute with debugger

Reusable debug script generation

Power-Buffer/Table Designer

Declarative deferred online schema management Brings “project-oriented” features to online / connected development Live errors and warnings as changes are made against code “Project-oriented” validation during editing

Table designer Code-behind designer Works on top of Power-Buffer (partial model) or project model Strives to be the same experience online as experienced in the

project system Coordinated execution of buffers against the same target

Diff scripts by default are transactional (Tools\Options\SQL Server Tools\Online Editing\Include transactional scripts)

Data Editor

View and Edit Data via grid editor Copy-Paste support Generate as INSERT to file or query window

Execute Procedure/Function

Dialog based input for parameter collection Generates SQL script for execution/debugging

PROJECT BASED DEVELOPMENT

Creating and Importing

Single project template VSDB note:

No distinction between server or user projects Server projects are projects with target database set to master

Import from: Database DACPAC SQL Script (multi-file import enabled) Selective import by using Schema Compare

“Create New Project” from SSOX Inherits version from source database

Folder Structure

Options on import: None Schema Object type Schema\Object type

Project Directory Guidelines…

Do not host more then one table inside script file Table designer will not see additional tables

inside script

Additional Language Services

Projects enable additional language services Go To Definition Find All References Refactoring

Rename (sp_rename) Move to Schema (ALTER SCHEMA schema_name

TRANSFER) Wildcard Expansion Fully Quality Name

Invoked from Editor, Table Designer and SQL Server Object Explorer for project based schema objects

T-SQL Static Code Analysis

Rule set Suppression

File level Project level

MSBuild support

Multi-Targeting

Target version aware: SQL Server 2005 SQL Server 2008 & SQL Server 2008 R2 SQL Server 2012 SQL Azure

Isolated Sandbox

F5 – Run by default configure to use the LocalDB instance associated with the project Data Source=(localdb)\<project name>;Initial

Catalog=<project name>;Integrated Security=True;Pooling=False;Connect Timeout=30

To retarget to a different SQL Server version and/or shared SQL Server change: Project properties\Debug\Target Connection

String

SQL Server 2012 Express LocalDB

Simplify embedded usage of SQL Server Simple installation Zero-admin database

Same programming surface as User Instances of SQL Express The same sqlservr.exe as in service-based SQL Server with the same language and

features Connection through the same client-side APIs, using a new connection string option

SQL Server programming symmetry Installation similar to .NET Framework model

One set of installed binaries (per major version), no global configuration, no constantly-running service

Activation model similar to RANU (Access, SQL Compact, …) The application connects to a database file, SQL activates automatically No service: SQL process starts in the context of current user

Default connection string (localdb)\v11.0

Build Time Validation

Build validates the complete model Platform specific validation

Example – Enforces clustered index requirement on tables in SQL Azure

Integration with Compiler Services Engine-level build-time validation without schema

deployment

Pre & Post Deployment scripts Build validates syntactical correctness of pre- and

post- deployment scripts using the SQLCMD variables

Build Actions

Build - This script will be interpreted as T-SQL (or an XML Schema in the case of XML Schema Collections) and reflected in the T-SQL Model

Compile - C# or VB (depending on your project properties) to be deployed as a SQLCLR assembly

None - Use this for any loose artifacts (like text files) PreDeploy - The pre deployment master script (there can only be one) PostDeploy - The post deployment master script (there can only be

one) RefactorLog - This is a refactor log which notifies the DaxFx

deployment engine that particular changes should be interpreted as refactoring operations and not drop/adds

Build Extension Configuration - Reserved for future use, for this is interpreted as None

Pre & Post Deployment Scripts

Can be used for any “arbitrary” SQL actions that you need to perform “before” and “after” deployment of the schema objects

The pre deployment block comes after the generic database context validation block

The post deployment block comes after the schema objects block

Pre and post deployment scripts must be idempotent They are “executed” each deployment! http://blogs.msdn.com/gertd/archive/2007/01/25/idempote

What is a Data-Tier Application (dacpac)?

Data-Tier Application Component (DAC) SQL Server database registered as Data-Tier Application

Component

DAC is a self contained entity of a database used by an application Unit of deployment and management

Authored along side your application code Compiled into a DAC package (DACPAC)

Extracted for existing databases Database extracted (DACPAC) or exported (BACPAC) into

packages

Package is deployable to SQL Server and SQL Azure

DACFX Packages

.dacpac - Packaged Schema representing the declarative model of the database Not SQL, but a declarative Schema Model representation of the database Compiled from source code or Extracted from existing databases Deploy as new database or Incremental Upgrade an existing database Supports all SQL Server Objects and Types

.bacpac - Packaged Schema and Data representing the state of the database Composed of Schema Model with stateful properties and Data Streams Exported from existing databases Imported as a new database or populates an empty database Supports most SQL Server Objects and Types (SQL Azure parity)

DAC Framework v3.0 (DACFX)

Core SQL Server redist component providing modeling, reverse engineering and deployment capabilities

Managed Public API Exposes verbs for DACPAC and BACPAC

package operations

Command-line tool (SqlPackage.exe) Executable over the managed public API

03/29/2012

Database Schema Snapshots

Point-in-time representation of schema model Model must be “error-free” state Produces same file format (*.dacpac) as build or

extract

To be used for: Versioning Comparison Sharing schema definitions or changes

Schema Compare

Performs a model comparison between: Databases Projects DACPAC files (snapshots, build outputs, extracts)

Supports: Refactoring log SQLCMD variables

Schema CompareNext and Previous move between top-level objects, no longer expand the tree.

Simpler set of columns are aligned around the central action column echoes alignment of schemas above

Group-by Action is the default

Same column order is used for all groupings; cleaner and easier to parse regardless of grouping

Schema no longer used as a parent for top-level objects; only shown when changed

Improved script diff’ algorithm for tables emphasizes columns as unit of change. Gives much improved alignment. Also improved look
