博客园-乱世重典

因为CHSNS的SQL Server布署有很多朋友反映很麻烦,所以正在将它迁移到Sqlite上,并做一些调整,使整个网站更加轻快查询当然是linq比较好,但是寻找很久,网上却没有找到CodeSmith生成Sqlite的资料,只是在一些文章中提到要使用 Improved SQLite 3 Schema Provider
于是下载了一份,但是发现其中有几个问题
下载地址:http://community.codesmithtools.com/files/folders/schemaproviders/entry21748.aspx
以下一一解决:
1.工程引用的SchemaExplorer.dll版本过低,于是改为引用 \Program Files\CodeSmith\v4.1\AddIns\SchemaExplorer.dll
由此引发编译通不过,是因为IDbSchemaProvider接口有了更新,重新实现接口,会发现多了一个SetExtendedProperties方法.

      #region IDbSchemaProvider 成员
      public void SetExtendedProperties(string connectionString, SchemaObjectBase schemaObject) {
          throw new NotImplementedException();
      }
      #endregion

不用鸟它,因为Sql,mySql那些都是这样的.
2.编译后发现所有字段都是OBJECT....都打回原型了...
更改SchemaColumns.cs中的SQLiteDataTypes为

#region SQLiteDataTypes
   public static class SQLiteDataTypes
   {
      public const string INTEGER = "integer";
      public const string FLOAT = "float";
      public const string REAL = "real";

      public const string NUMERIC = "numeric";
      public const string BOOLEAN = "boolean";
      public const string TIME = "time";
      public const string DATE = "date";
      public const string TIMESTAMP = "timestamp";
      public const string VARCHAR = "varchar";
      public const string NVARCHAR = "nvarchar";
      public const string TEXT = "text";
      public const string NONE = "none";
      public const string BLOB = "blob";
      public const string CHAR = "char";
   }

   #endregion SQLiteDataTypes

然后将Sqlite3SchemaProvider.cs中的DbTypeFromType方法改为

private DbType DbTypeFromType (string p)
      {
         //SQLite has only a few types:
         // INTEGER == Int64
         // NUMERIC == Decimal
         // TEXT == String
         // NONE == Object or Blob
         switch (p)
         {
            /*
            case "System.Int64":
                return DbType.Int64;

            case "System.Decimal":
                return DbType.Decimal;

            case "System.String":
                return DbType.String;
            */
            case SQLiteDataTypes.INTEGER:
               return DbType.Int64;

            case SQLiteDataTypes.NUMERIC:
               return DbType.Decimal;

            case SQLiteDataTypes.FLOAT:
               return DbType.Single;
             case SQLiteDataTypes.REAL:
               return DbType.Double;
            case SQLiteDataTypes.TEXT:
            case SQLiteDataTypes.VARCHAR:
             case SQLiteDataTypes.NVARCHAR:
            case SQLiteDataTypes.CHAR:
               return DbType.String;
             case SQLiteDataTypes.DATE:
             case SQLiteDataTypes.TIME:
             case SQLiteDataTypes.TIMESTAMP:
               return DbType.DateTime;
            default:
               return DbType.Object;
         }
      }

OVER

将编译后的Sqlite3SchemaProvider.dll和System.Data.SQLite.dll复制到\Program Files\CodeSmith\v4.1\SchemaProviders
再用CodeSmith4 新建数据库连接时就会发现多了一个Sqlite的SchemaProvider
DLL下载... 吼吼...
