ODBC accomplishes DBMS independence by using an ODBC driver as a translation layer between the application and the DBMS. The application uses ODBC functions through an ODBC driver manager with which it is linked, and the driver passes the query to the DBMS. An ODBC driver can be thought of as analogous to a printer driver or other driver ...
The driver that Microsoft provides in MDAC is called the SQL Server ODBC Driver (SQLODBC), and (as the name implies) is designed for Microsoft's SQL Server. It supports SQL Server v6.5 and upwards. [3] ODBC allows programs to use SQL requests that will access databases without having to know the proprietary interfaces to the databases. It ...
a remote provider and server (see RDS), using the syntax "Remote provider=" and "Remote server="; or; an absolute URL, using the syntax "URL=" Command After the connection object establishes a session to the data source, instructions are sent to the data provider via the command object.
OLE DB providers are analogous to ODBC drivers, JDBC drivers, and ADO.NET data providers. OLE DB providers can be created to access such simple data stores as a text file and spreadsheet, through to such complex databases as Oracle, Microsoft SQL Server, Sybase ASE, and many others. It can also provide access to hierarchical data stores such as ...
SQL refers to Structured Query Language, a kind of language used to access, update and manipulate database. In SQL, ROLLBACK is a command that causes all data changes since the last START TRANSACTION or BEGIN to be discarded by the relational database management systems (RDBMS), so that the state of the data is "rolled back" to the way it was before those changes were made.
Type 1 that calls native code of the locally available ODBC driver. (Note: In JDBC 4.2, JDBC-ODBC bridge has been removed [15]) Type 2 that calls database vendor native library on a client side. This code then talks to database over the network. Type 3, the pure-java driver that talks with the server-side middleware that then talks to the database.
During the taste test, editors rated each cream cheese on a scale from 1 to 5, with 1 being the lowest and 5 being the highest. After tasting all the cream cheese, they determined their favorite ...
You can add Microsoft ODBC drivers as needed to the built-in ODBC socket. Optionally, Borland's SQL Links product provides access to a range of database management systems (DBMS), including Informix, IBM Db2, InterBase, Oracle, and Sybase. BDE is object-oriented in design. At runtime, application developers interact with BDE by creating various ...
