Elevatedb Vcl Add Php Dac Version 2.27 Build 1 Apr 2026

: Use TEDBQuery with FetchAll := False for large result sets to reduce memory footprint. 2. PHP Web Application (Linux + Apache) Scenario : A reporting dashboard that needs to query ElevateDB without MySQL/PostgreSQL overhead.

| Component Set | Primary Use Case | Key Improvement in Build 1 | |---------------|----------------------------------------|-----------------------------------------------------| | VCL | Windows desktop apps (Delphi 7–11) | Improved transaction isolation with TEDBQuery | | ADO.NET | .NET Framework 4.8 / .NET 6+ (limited) | Better connection pooling in ASP.NET apps | | PHP | Linux/Windows web apps (PHP 7.4–8.2) | Fixed prepared statement memory leak | | DAC | Low-level direct engine access | Added TEDBDatabase.ValidateTable() method | : The ADO.NET provider is now in maintenance mode. New projects should consider the DAC layer via OLE DB or ODBC bridge if full .NET Core support is required. Practical Use Cases 1. Building a Multi-Tier Delphi Application (VCL + DAC) Scenario : A hospital management system needs local caching with occasional sync to a central ElevateDB server.
