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. In a Recordset object, each of the Field objects that make up the Fields collection corresponds to a column in that Recordset object.
Populate the recordset by opening it and passing the desired table name or SQL statement as a parameter to open function. Do all the desired searching/processing on the fetched data. Commit the changes you made to the data (if any) by using Update or UpdateBatch methods. Close the recordset; Close the connection
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.
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 ...
A DataReader parses a Tabular Data Stream from Microsoft SQL Server, and other methods of retrieving data from other sources. A DataReader is usually accompanied by a Command object that contains the query, optionally any parameters, and the connection object to run the query on.
An ADO.NET-ODBC bridge consists of an ADO.NET Provider which uses the services of an ODBC driver to connect to a target database. This provider translates ADO.NET method calls into ODBC function calls. Programmers usually use such a bridge when a given database lacks an ADO.NET provider, but is accessible through an ODBC driver.
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.
ADOdb Lite is a very small, fast ADOdb-compatible database abstraction library written in PHP. It uses less than 100 kB of system RAM for each HTTP access compared to over 640 kB for ADOdb . After a benchmark ADOdb Lite is also 300% faster than the ADOdb library [ citation needed ] .
