TSQLConnection

TSqlConnection is a class found in the Embarcadero Delphi and C++Builder component libraries, specifically within the dbxCommon and dbxMSAccess data access frameworks. It is designed to establish and manage connections to Microsoft SQL Server databases. The TSqlConnection component acts as an intermediary between a Delphi or C++Builder application and the SQL Server, facilitating data retrieval and manipulation operations.

When using TSqlConnection, developers specify connection parameters such as the server name, database name, and authentication details (e.g., username and password, or Windows authentication). The component then utilizes underlying database drivers and communication protocols to establish a live link to the SQL Server instance. Once a connection is established, other data access components, such as TSQLQuery or TSQLTable, can leverage the TSqlConnection to execute SQL statements and interact with the database. Error handling and connection management features are typically provided by the TSqlConnection class to ensure robust database interactions within the application. It is a fundamental building block for applications requiring direct access to Microsoft SQL Server data.
