创建实例-IDbOperator\IFactoryDbOperator
MySql
需要先在项目里引用或加载MySql官方库MySql.Data.dll。
IDbOperator _dber = new MySqlFactoryOperator() { ConnectionString = "server=127.0.0.1;database=test;uid=user;pwd=testpassword;Connect Timeout=18000" };
SQLite
需要先在项目里引用或加载Sqlite官方库System.Data.SQLite.dll。
IDbOperator _dber = new SQLiteFactoryOperator() { ConnectionString = "Data Source=.\data\test.db3;" };

// Execute(执行多条SQL) var _parameters = new List<DbParameter>() { _dber.CreateParameter("Value1","ID123"), _dber.CreateParameter("Value2","Name123"), _dber.CreateParameter("Value3","Name1456"), }; var _sqls = new string[] { @"insert table3 (Values) values (@Value1);", @"insert table3 (Values) values (@Value2);", @"insert table3 (Values) values (@Value3);", } ; var _count = _dber.Execute(_sqls, _parameters);//直接执行SQL //var _count = _dber.Execute(true, _sqls, _parameters);// 使用事务执行SQL return _count >= 1;
ExecuteTransaction(使用事务执行指定的SQL)
// ExecuteTransaction(使用事务执行指定的SQL) public void ExecuteTransaction() { _dber.StartTransaction(); try { for (int i = 0; i < 3; i++) { var _parameters = new List<DbParameter>() { _dber.CreateParameter("ID",i.ToString()), _dber.CreateParameter("Name","Name123"), _dber.CreateParameter("CreateTime",DateTime.Now), }; var _sql = @"insert table1 (ID,Name,CreateTime) values (@ID,@Name,@CreateTime);"; var _isSucceed = _dber.ExecuteTransaction(_sql, _parameters); } } catch (Exception ex) { _dber.RollbackTransaction(); return; } _dber.FinishTransaction(); }
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(); _dber.StartTransaction(_key); var _id = i.ToString() + DateTime.Now.ToLongTimeString(); try { var _parameters = new List<DbParameter>() { _dber.CreateParameter("ID",_id), _dber.CreateParameter("Name","Name123"), _dber.CreateParameter("CreateTime",DateTime.Now), }; var _sql = @"insert table1 (ID,Name,CreateTime) values (@ID,@Name,@CreateTime);"; var _isSucceed = _dber.ExecuteTransaction(_key, _sql, _parameters); } catch (Exception ex) { _dber.RollbackTransaction(_key); return; } if (!_dber.FinishTransaction(_key)) { return; } } }
RollbackTransaction(回滚指定的事务)
// RollbackTransaction(回滚指定的事务) public void RollbackTransaction() { var _key = "Transaction"; _dber.StartTransaction(_key); var _id = nameof(RollbackTransaction); try { var _parameters = new List<DbParameter>() { _dber.CreateParameter("ID",_id), _dber.CreateParameter("Name","Name123"), _dber.CreateParameter("CreateTime",DateTime.Now), }; var _sql = @"insert table1 (ID,Name,CreateTime) values (@ID,@Name,@CreateTime);"; var _isSucceed = _dber.ExecuteTransaction(_key, _sql, _parameters); } catch (Exception ex) { _dber.RollbackTransaction(_key); return; } _dber.RollbackTransaction(_key); }
QueryTable(查询数据,并返回DataTable)
public DataTable QueryTable() { var _parameters = new List<DbParameter>() { _dber.CreateParameter("ID",123), }; var _sql = "select * from table1 where ID=@ID;"; return _dber.QueryTable(_sql, _parameters); }
QueryTables(查询数据,并返回DataSet)
public DataSet QueryTables() { var _parameters = new List<DbParameter>() { _dber.CreateParameter("ID",123), }; var _sql = "select * from table1 where ID=@ID;"; _sql += "select * from table2 where ID=@ID;"; return _dber.QueryTables(_sql, _parameters); }
QueryReader(查询数据,并返回DbDataReader)
public QueryReader QueryReader()
{
var _parameters = new List<DbParameter>()
{
_dber.CreateParameter("ID",123),
};
var _sql = "select * from table1 where ID=@ID;";
return _dber.QueryReader(_sql, _parameters);
}

{
var _sql = "select Key,Value from table1 ;";
return _dber.QueryDictionary<string, string>(_sql);
}
