Oracle to PostgreSQL

Migrate Oracle workloads to PostgreSQL without losing behavior, logic, or control. Even the most complex PL/SQL code is automatically converted and emulated in PostgreSQL.

shape

This is not syntax conversion.
This is behavioral preservation.

Oracle-to-PostgreSQL migrations fail when teams underestimate how deeply Oracle-specific their systems really are. SQL Tran was built specifically to handle that reality. It understands Oracle semantics at scale and translates them into PostgreSQL equivalents, automatically, repeatably, and safely.

Oracle databases are not just SQL. They are built of:

Packages, views, functions procedures, object types, complex transactions

Advanced and highly optimized PL/SQL constructs

Database-resident business logic accumulated over decades

PostgreSQL is powerful - but it is not Oracle

Manual rewrites inevitably introduce regressions, delays, and risk. Most tools stop at surface-level translation and that’s why migrations are infamous for being a high-risk and expensive endeavor.

SQL Tran was designed for complex Oracle codebases

It uses deep static analysis and a large, ever-growing emulation layer to bridge the gap between Oracle and PostgreSQL. It includes hundreds of built-in emulations, covering both common and deeply obscure Oracle features, including:

SQL Tran doesn’t just rewrite logic. It transforms it into idiomatic Postgres code that behaves exactly the same. SQL Tran parses and analyzes every object:

Types

Oracle has rich and complex type system, and SQL Tran handles it all, from simple types to the most complex user-defined ones.

Tables and partitions

Table definitions are properly analyzed and translated, including complex partitioning schemes.

👁
Views

Even the most complex views are translated correctly. For example, old-style join syntax is properly handled and converted to modern explicit ones.

Procedures

Procedural code is deeply analyzed, and translated to equivalent Postgres logic, using emulation where necessary to ensure identical behavior. Even nested procedures are optimally rewritten.

ƒ
Functions

Scalar, table-valued, and aggregate functions are fully supported.

Triggers

Triggers are translated with full fidelity, including complex firing rules and mutating table access.

Nothing is treated in isolation

Dependencies across schemas are analyzed and a full object dependency map is built. Broken references are located and reported, whether they are result of missing objects in your SQL script or dropped objects breaking your database code.

Oracle constructs are translated with full awareness of intent, not just syntax.

  • Thanks to a super-fast and fully custom parsers, translation of even the largest codebases is practically instant.
  • Packages are decomposed safely
  • Oracle-only features are mapped or emulated
  • PostgreSQL-native constructs are used where appropriate
  • Assessment is instant and detailed – a report of a complete translation with deep statistics.

SQL Tran's powerful testing framework is the ultimate project enabler:

  • Even if all you have is a SQL schema dump you can run correctness and performance testing
  • Generate synthetic test data tailored to your source and target schema
  • Ensure functions return the same results
  • Ensure procedures affect tables identically
  • Ensure edge cases and emulations are handled correctly

Trust is earned, not assumed.
