- 安装依赖：
Install-Package DBUtil- 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");- 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;"); - 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- 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%")
});- ID生成
int id = iDb.IDSNOManager.NewID(iDb, "test", "id");
