建议将DbProvider的配置放到配置文件中 about smartsql

[Ahoo-Wang]

你可以直接定义 Type 的。

[Ahoo-Wang]

现在也不需要修改代码呀。
因为 DbProvider 相对来说是比较稳定的，所以硬编码到代码层面了，所以我们我也不需要自己维护 providers。这样其实更方便了，只要写一个 DbProvider 名称就可以了。

之前帮一个群友对接人大金仓数据库，就得在DbProvider里去添加东西。如果是通过配置文件配置，就不需要修改源码。

[Ahoo-Wang]

为什么需要修改源码啊？

直接填上这个就可以啦。

这里的Name的值是不是得DbProvider.cs定义的常量里存在

SmartSql/src/SmartSql/DataSource/DbProvider.cs

Lines 10 to 17 in cbc9c45

	public const String SQLSERVER = "SqlServer";
	public const String MS_SQLSERVER = "MsSqlServer";
	public const String MYSQL = "MySql";
	public const String MYSQL_CONNECTOR = "MySqlConnector";
	public const String POSTGRESQL = "PostgreSql";
	public const String ORACLE = "Oracle";
	public const String SQLITE = "SQLite";

同时DbProviderManager.cs里定义的常量存在对应的DbProvider

SmartSql/src/SmartSql/DataSource/DbProviderManager.cs

Lines 13 to 66 in cbc9c45

	public static readonly DbProvider SQLSERVER_DBPROVIDER = new DbProvider
	{
	Name = DbProvider.SQLSERVER,
	ParameterPrefix = "@",
	Type = "System.Data.SqlClient.SqlClientFactory,System.Data.SqlClient",
	SelectAutoIncrement = ";Select Scope_Identity();"
	};
	public static readonly DbProvider MS_SQLSERVER_DBPROVIDER = new DbProvider
	{
	Name = DbProvider.MS_SQLSERVER,
	ParameterPrefix = "@",
	Type = "Microsoft.Data.SqlClient.SqlClientFactory,Microsoft.Data.SqlClient",
	SelectAutoIncrement = ";Select Scope_Identity();"
	};
	public static readonly DbProvider MYSQL_DBPROVIDER = new DbProvider
	{
	Name = DbProvider.MYSQL,
	ParameterPrefix = "?",
	Type = "MySql.Data.MySqlClient.MySqlClientFactory,MySql.Data",
	SelectAutoIncrement = ";Select Last_Insert_Id();"
	};
	public static readonly DbProvider MYSQL_CONNECTOR_DBPROVIDER = new DbProvider
	{
	Name = DbProvider.MYSQL_CONNECTOR,
	ParameterPrefix = "?",
	Type = "MySqlConnector.MySqlConnectorFactory,MySqlConnector",
	SelectAutoIncrement = ";Select Last_Insert_Id();"
	};
	public static readonly DbProvider POSTGRESQL_DBPROVIDER = new DbProvider
	{
	Name = DbProvider.POSTGRESQL,
	ParameterPrefix = "@",
	Type = "Npgsql.NpgsqlFactory,Npgsql",
	SelectAutoIncrement = "Returning *;"
	};
	public static readonly DbProvider ORACLE_DBPROVIDER = new DbProvider
	{
	Name = DbProvider.ORACLE,
	ParameterPrefix = ":",
	Type = "Oracle.ManagedDataAccess.Client.OracleClientFactory,Oracle.ManagedDataAccess",
	SelectAutoIncrement = ""
	};
	public static readonly DbProvider SQLITE_DBPROVIDER = new DbProvider
	{
	Name = DbProvider.SQLITE,
	ParameterPrefix = "@",
	Type = "System.Data.SQLite.SQLiteFactory,System.Data.SQLite",
	SelectAutoIncrement = ""
	};

然后在构造函数里Add对应的Provider

SmartSql/src/SmartSql/DataSource/DbProviderManager.cs

Lines 70 to 79 in cbc9c45

	private DbProviderManager()
	{
	_dbProviders.Add(DbProvider.SQLSERVER, SQLSERVER_DBPROVIDER);
	_dbProviders.Add(DbProvider.MS_SQLSERVER, MS_SQLSERVER_DBPROVIDER);
	_dbProviders.Add(DbProvider.POSTGRESQL, POSTGRESQL_DBPROVIDER);
	_dbProviders.Add(DbProvider.MYSQL, MYSQL_DBPROVIDER);
	_dbProviders.Add(DbProvider.MYSQL_CONNECTOR, MYSQL_CONNECTOR_DBPROVIDER);
	_dbProviders.Add(DbProvider.ORACLE, ORACLE_DBPROVIDER);
	_dbProviders.Add(DbProvider.SQLITE, SQLITE_DBPROVIDER);
	}

你是不是没有安装
SmartSql.Schema，所以没有看到智能提示？

[xiangxiren]

明白了……

[xiangxiren]

你是不是没有安装
SmartSql.Schema，所以没有看到智能提示？

装了啊，有提示。但这个地方一般就想着设置一个Name。认为对应的Type都是在代码里定义好了的。

应用还有人跟你有相同的问题，有兴趣的话可以一起参与一下文档共建。https://github.com/Smart-Kit/SmartSql-Docs

ok

没啥其他问题的话就把issue关掉吧。
