dbExpress driver for SQL Server is a database-independent layer that defines common interface to provide fast access to SQL Server from Delphi and C++Builder including Community Edition on Windows and macOS for both 32-bit and 64-bit platforms.

For this server, dbExpress provides a driver as an independent library that implements the common dbExpress interface for processing queries and stored procedures.

As the data-access layer is thin and simple, dbExpress provides high performance database connectivity and is easy to deploy. You can use the driver in the same way as the one supplied by Embarcadero.

Native Connectivity to SQL Server
Applications based on the app for SQL Server are easy to deploy, do not require installation of other data provider layers (such as BDE and ODBC), and that's why they can work faster than the ones based on standard Delphi data connectivity solutions. Moreover, dbExpress Driver for SQL Server provides working with SQL Server not only through OLE DB but through SQL Native Client as well.

Developing in Delphi and C++Builder
This tool for SQL Server is a cross-IDE solution for developing applications for Windows and macOS: RAD Studio, Delphi, and C++Builder for both x86 and x64 platforms. dbExpress driver for SQL Server also provides support for the FireMonkey platform, which allows you to develop visually spectacular high-performance native applications for Windows and macOS.

Features and Highlights

Performance
All these components and libraries are designed to help you write high-performance, lightweight data access layers, therefore they use advanced data access algorithms and techniques of optimization.

Database Compatibility
SQL Server 2017\2016\2014\2012\2008 R2\2008\2005 (including Express edition), SQL Server 2000 (including MSDE), SQL Server 7, SQL Server Compact 4.0\3.5\3.1, SQL Azure.

64-bit Development
The app for SQL Server doesn't limit your choice of the development platform. Now you can develop for 32-bit and 64-bit platforms with Delphi.

dbMonitor
Use the freeware dbMonitor tool to monitor and analyze all the DB calls made by your application using dbExpressDriver for SQL Server. dbMonitor performs percomponent tracing of SQL statement execution, commits, rollbacks, etc.

IDE Compatibility
The product is compatible with the latest IDE versions and editions including Community Edition: Embarcadero RAD Studio 10.3 Rio, Delphi 10.3 Rio, and C++Builder 10.3 Rio. It is also compatible with the previous IDE versions since Delphi 6 and C++Builder 6.

IDE Compatibility
Now you can develop not only VCL-based applications in Delphi but also use the newest FireMonkey application development platform.
