.Net 应用Petapoco 生成数据库表实体附加注释的修改
本次修改Petapoco版本为5.1.304
之前开发项目使用.Net版的Ibatis进行数据库访问，期间的复杂性不赘述了，直到使用了Petapoco 之后才发现真香，大大缩减了开发时间
但是对于Petapoco 生成的数据库表实体，没有对应的注释，这就用起来有些麻烦，每次找对应字段都要扒拉数据库设计文档
于是乎，决定调整生成数据库表实体的模板
在网上找了不少文章，最终形成如下成果

It is based on the SubSonic T4 templates but has been considerably re-organized and reduced ----------------------------------------------------------------------------------------- This template can read minimal schema information from the following databases: * SQL Server * SQL Server CE * MySQL * PostGreSQL * Oracle For connection and provider settings the template will look for the web.config or app.config file of the containing Visual Studio project. It will not however read DbProvider settings from this file. In order to work, the appropriate driver must be registered in the system machine.config file. If you're using Visual Studio 2010 the file you want is here: C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\machine.config If you are using VS2015 or VS2017 you may also need to update machine.config file located here: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\machine.config After making changes to machine.config you will also need to restart Visual Studio. Here's a typical set of entries that might help if you're stuck: <system.data> <DbProviderFactories> <add name="Odbc Data Provider" invariant="System.Data.Odbc" description=".Net Framework Data Provider for Odbc" type="System.Data.Odbc.OdbcFactory, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/> <add name="OleDb Data Provider" invariant="System.Data.OleDb" description=".Net Framework Data Provider for OleDb" type="System.Data.OleDb.OleDbFactory, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/> <add name="OracleClient Data Provider" invariant="System.Data.OracleClient" description=".Net Framework Data Provider for Oracle" type="System.Data.OracleClient.OracleClientFactory, System.Data.OracleClient, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/> <add name="SqlClient Data Provider" invariant="System.Data.SqlClient" description=".Net Framework Data Provider for SqlServer" type="System.Data.SqlClient.SqlClientFactory, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/> <add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.3.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"/> <add name="Microsoft SQL Server Compact Data Provider" invariant="System.Data.SqlServerCe.3.5" description=".NET Framework Data Provider for Microsoft SQL Server Compact" type="System.Data.SqlServerCe.SqlCeProviderFactory, System.Data.SqlServerCe, Version=3.5.1.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"/><add name="Microsoft SQL Server Compact Data Provider 4.0" invariant="System.Data.SqlServerCe.4.0" description=".NET Framework Data Provider for Microsoft SQL Server Compact" type="System.Data.SqlServerCe.SqlCeProviderFactory, System.Data.SqlServerCe, Version=4.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"/> <add name="Npgsql" invariant="Npgsql" description=".NET Data Provider for PostgreSQL" type="Npgsql.NpgsqlFactory, Npgsql, Version=3.2.2.0, Culture=neutral, PublicKeyToken=5d8b90d52f46fda7"/> </DbProviderFactories> </system.data> Also, the providers and their dependencies need to be installed to GAC.
