Criação de Contact usando CLR e XML
O exemplo Contact do SQL Server fornece alguns utilitários úteis que formam uma camada de funcionalidade extra no banco de dados de exemplo base AdventureWorks2012. O primeiro utilitário cria registros de contato para vários tipos de pessoas envolvidas no banco de dados AdventureWorks2012. As informações de contato são especificadas por meio de XML e são passadas para um procedimento armazenado baseado no C# ou no VB para criar o XML e colocá-las nas tabelas adequadas no banco de dados.
Pré-requisitos
Para criar e executar este projeto, o software a seguir deve estar instalado:
SQL Server ou SQL Server Express. Você pode obter SQL Server Express gratuitamente no site de Documentação e Exemplos do SQL Server Express
O banco de dados AdventureWorks que está disponível no site do SQL Server Developer
.NET Framework SDK 2.0 ou posterior ou Microsoft Visual Studio 2005 ou posterior. Você pode obter o .NET Framework SDK gratuitamente.
Além disso, as seguintes condições devem ser atendidas:
A instância SQL Server que você está usando deve ter a integração CLR habilitada.
Para habilitar a integração CLR, execute as etapas a seguir:
Habilitando integração CLR
- Execute os seguintes comandos Transact-SQL:
sp_configure 'clr enabled', 1GORECONFIGUREGOObservação
Para habilitar o CLR, é necessário ter a permissão
ALTER SETTINGSem nível de servidor, que é mantida implicitamente por membros das funções de servidor fixassysadmineserveradminO banco de dados AdventureWorks deve ser instalado na instância SQL Server que você está usando.
Se você não for um administrador da instância de SQL Server que está usando, deverá ter uma permissão CreateAssembly concedida ao administrador para concluir a instalação.
Compilando o exemplo
Crie e execute o exemplo seguindo estas instruções:
Abra um prompt de comando do Visual Studio ou do .NET Framework.
Se necessário, crie um diretório para o seu exemplo. Para este exemplo, usaremos C:\MySample.
Em c:\MySample, crie
Contacts.vb(para o exemplo do Visual Basic) ouContacts.cs(para o exemplo do C#) e copie o código de exemplo adequado do Visual Basic ou do C# (a seguir) no arquivo.Compile o código de exemplo no prompt de linha de comando executando uma das seguintes ações, de acordo com sua opção de linguagem.
Vbc /reference:C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Data.dll,C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.dll,C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Xml.dll /target:library Contacts.vbCsc /reference:C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Data.dll /reference:C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.dll /reference:C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.XML.dll /target:library Contacts.csCopie o código de instalação do Transact-SQL em um arquivo e salve-o como
Install.sqlno diretório de exemplo.Se o exemplo tiver sido instalado em um diretório diferente de
C:\MySample\, edite o arquivoInstall.sqlconforme indicado para apontar para esse local.Implante o assembly e o procedimento armazenado executando o seguinte
sqlcmd -E -I -i install.sql
Copie o script de comando de teste do Transact-SQL em um arquivo e salve-o como
test.sqlno diretório de exemplo.Execute o script de teste com o seguinte comando
sqlcmd -E -I -i test.sql
Copie o script de limpeza Transact-SQL em um arquivo e salve-o como
cleanup.sqlno diretório de exemplo.Execute o script com o seguinte comando
sqlcmd -E -I -i cleanup.sql
