注意：相比windows版本的dbutil，这个包不支持access、excel等oledb连接，sqlite数据库不支持密码

DBUtil.Standard

.net standard 2.0 下常用的数据库访问工具,支持sqlserver、oracle、mysql、postgresql、sqlite 运行平台：.net standard 2.0

使用说明

1. 安装依赖：

Install-Package DBUtil.Standard -Version 1.0.0

2. 创建数据库操作对象

DBUtil.IDbAccess iDb = DBUtil.IDBFactory.CreateIDB("Data Source=.;Initial Catalog=JACKOA;User ID=sa;Password=xx;","SQLSERVER");

3. 查询

String str=iDb.GetFirstColumnString("select Name from SysUser");
DataTable dt = iDb.GetDataTable("select * from test2");
DataSet ds = iDb.GetDataSet("select * from test2;select * from test2;"); 

4. 分页查询

DBUtil.IDbAccess iDb = DBUtil.IDBFactory.CreateIDB(@"Data Source=localhost;Initial Catalog=imgserver2;User ID=root;Password=123456;", "MYSQL");
string selectSql = "select * from test2";
string orderSql = "order by id desc";
int pageSize = 10;
int pageIndex = 1;
string sqlFinal = iDb.GetSqlForPageSize(selectSql, orderSql, pageSize, pageIndex);
Console.WriteLine(sqlFinal);//select * from test2 order by id desc limit 0,10

5. 参数化sql

DataTable dt = iDb.GetDataTable(string.Format("select * from test2 where name like {0}", iDb.paraPrefix + "name"), new IDbDataParameter[] {
      iDb.CreatePara("name","%小%")
 });

6. ID生成

int id = iDb.IDSNOManager.NewID(iDb, "test", "id");
