A programmer can directly access ADO objects to manipulate data, or can send an SQL query to the database via several ADO mechanisms. ADO is made up of nine objects and four collections. The collections are: Fields: This collection contains a set of Field objects. The collection can be used in either a Recordset object or in a Record object.
A RecordSet consists of a collection of Record objects. Stream A stream, mainly used in a RecordSet object, is a means of reading and writing a stream of bytes. It is mostly used to save a recordset in an XML format, to send commands to an OLE DB provider as an alternative to the CommandText object and to contain the contents of a binary or ...
The server object allows connections to databases (ADO), filesystem, and use of components installed on the server. < % Dim oAdoCon , oAdoRec , oAdoStm , oCdoCon , oCdoMsg , oSciDic , oSciFsm , oMswAdr Set oAdoCon = Server .
A recordset is a data structure that consists of a group of database records, and can either come from a base table or as the result of a query to the table. The concept is common to a number of platforms, notably Microsoft's Data Access Objects (DAO) and ActiveX Data Objects (ADO). The Recordset object contains a Fields collection, and a ...
ADOdb is a database abstraction library for PHP, originally based on the same concept as Microsoft's ActiveX Data Objects.It allows developers to write applications in a consistent way regardless of the underlying database system storing the information.
ADO.NET Entity Framework uses the EDM to actually perform the mapping letting the application work with the entities, while internally abstracting the use of ADO.NET constructs like DataSet and RecordSet. ADO.NET Entity Framework performs the joins necessary to have entity reference information from multiple tables, or when a relationship is ...
ADO.NET is a data access technology from the Microsoft.NET Framework that provides communication between relational and non-relational systems through a common set of components. [1] ADO.NET is a set of computer software components that programmers can use to access data and data services from a database.
In ADO.NET, a DataReader is a broad category of objects used to sequentially read data from a data source. [1] DataReaders provide a very efficient way to access data, and can be thought of as a Firehose cursor from ASP Classic, except that no server-side cursor is used.
