SQL Server

SQL Server Compatibility in PostgreSQL

100% SQL Server (T-SQL) routine compatibility

SQL Server (T-SQL) functions, data types, and operators on Community PostgreSQL - DATEADD, DATEDIFF, CHARINDEX, ISNULL, TRY_CONVERT, COMPRESS, OPENJSON, nvarchar, and hierarchyid - all at native speed.

Explore SQL Server compatibility

AI and migration tools cannot recreate Oracle and SQL Server built-in routines on PostgreSQL.HexaBridge does - so HexaRocket can deliver 100% automatic schema conversion.

Why HexaBridge

Two databases, one extension family

Move Oracle and SQL Server workloads onto Community PostgreSQL without rewriting every function, type, and built-in by hand.

No proprietary fork required

HexaBridge installs on standard Community PostgreSQL with a simple CREATE EXTENSION. No commercial database fork, no lock-in.

Exact semantics, not stubs

Boundary-crossing date math, NULL handling, collation, and edge cases behave the way Oracle and SQL Server do - not just same-named placeholders.

Native speed

Logic-heavy functions are written in C; direct maps are inlined by the planner, so compatibility does not cost you performance.
