使用说明

创建实例

  1. MySql

    需要先在项目里引用或加载MySql官方库MySql.Data.dll。

    IDbOperator _operator = new MySqlFactoryOperator()
    {
        ConnectionString = "server=127.0.0.1;database=test;uid=user;pwd=testpassword;Connect Timeout=18000"
    };
    
  2. SQLite

    需要先在项目里引用或加载Sqlite官方库System.Data.SQLite.dll。

    IDbOperator _operator = new SQLiteFactoryOperator()
    {
        ConnectionString = "Data Source=.\data\test.db3;"
    };
    
  3. Sql Server

    需要先在项目里引用或加载Sql Server官方库System.Data.SqlClient.dll。

    IDbOperator _operator = new SqlServerFactoryOperator()
    {
        ConnectionString = "Server=127.0.0.1;Database=test;Uid = user; Pwd=testpassword;"
    };
    

实例使用

  1. CanConnect(是否能够连接数据库)
    // CanConnect(是否能够连接数据库)
    if (_operator.CanConnect()) { return; }
    
  2. CreateParameter(创建相应的参数)
    // CreateParameter(创建相应的参数)
    return _operator.CreateParameter( "ID", 123);
    
  3. Execute(执行SQL)
    // Execute(执行SQL)
    var _parameters = new List<DbParameter>()
    {
        _operator.CreateParameter("ID","ID123"),
        _operator.CreateParameter("Name","Name123"),
        _operator.CreateParameter("CreateTime",DateTime.Now),
    };
    var _sql = @"insert table1 (ID,Name,CreateTime) values (@ID,@Name,@CreateTime);";
    var _count = _operator.Execute(_sql, _parameters);//直接执行SQL
    //var _count = _operator.Execute(true,_sql, _parameters);// 使用事务执行SQL
    return _count >= 1;
    
  4. ExecuteTransaction(使用指定的事务执行指定的SQL)
    // ExecuteTransaction(使用指定的事务执行指定的SQL)
    public void ExecuteTransaction()
    {
        for (int i = 0; i < 3; i++)
        {
            var _key = "Transaction" + i.ToString();
            _operator.StartTransaction(_key);
    
            var _id = i.ToString() + DateTime.Now.ToLongTimeString();
            try
            {
                var _parameters = new List<DbParameter>()
                {
                    _operator.CreateParameter("ID",_id),
                    _operator.CreateParameter("Name","Name123"),
                    _operator.CreateParameter("CreateTime",DateTime.Now),
                };
                var _sql = @"insert table1 (ID,Name,CreateTime) values (@ID,@Name,@CreateTime);";
                var _isSucceed = _operator.ExecuteTransaction(_key, _sql, _parameters);
            }
            catch (Exception ex)
            {
                _operator.RollbackTransaction(_key);
                return;
            }
    
            if (!_operator.FinishTransaction(_key))
            {
                return;
            }
        }
    }
    
    
  5. RollbackTransaction(回滚指定的事务)
    // RollbackTransaction(回滚指定的事务)
    public void RollbackTransaction()
    {
        var _key = "Transaction";
        _operator.StartTransaction(_key);
    
        var _id = nameof(RollbackTransaction);
    
        try
        {
            var _parameters = new List<DbParameter>()
            {
                _operator.CreateParameter("ID",_id),
                _operator.CreateParameter("Name","Name123"),
                _operator.CreateParameter("CreateTime",DateTime.Now),
            };
            var _sql = @"insert table1 (ID,Name,CreateTime) values (@ID,@Name,@CreateTime);";
            var _isSucceed = _operator.ExecuteTransaction(_key, _sql, _parameters);
        }
        catch (Exception ex)
        {
            _operator.RollbackTransaction(_key);
            return;
        }
    
        _operator.RollbackTransaction(_key);
    }
    
  6. QueryTable(查询数据,并返回DataTable)
    // QueryTable(查询数据,并返回DataTable)
    public DataTable QueryTable()
    {
        var _parameters = new List<DbParameter>()
        {
            _operator.CreateParameter("ID",123),
        };
        var _sql = "select * from table1 where ID=@ID;";
        var _table = _operator.QueryTable(_sql, _parameters);
        return _table;
    }
    
  7. QueryReader(查询数据,并返回DbDataReader)
    // QueryReader(查询数据,并返回DbDataReader)
    public QueryReader QueryReader()
    {
        var _parameters = new List<DbParameter>()
        {
            _operator.CreateParameter("ID",123),
        };
        var _sql = "select * from table1 where ID=@ID;";
        var _reader = _operator.QueryReader(_sql, _parameters);
        return _reader;
    }
