Sybase ASE & SQL Anywhere Migration: Convert T-SQL & Stored Procedures to Oracle 23ai.

SAP's sunsetting of mainstream roadmaps for Sybase Adaptive Server Enterprise (ASE) and SQL Anywhere has left financial, government, and PowerBuilder-heavy organizations exposed. Our automated T-SQL-to-PL/SQL AST transpiler converts Sybase schemas, temporary table patterns (`#temp`), cursor loops, and triggers into high-concurrency Oracle Database 23ai packages.

Sybase ASE & SQL Anywhere to Oracle 23ai · Problem Space & Technical Solution

SAP Sybase ASE & SQL Anywhere to Oracle Database 23ai Migration (T-SQL to PL/SQL)

Every conversion and modernization program requires separating legacy presentation artifacts from data-tier business rules so your modernized platform runs faster, costs less to license, and stays upgrade-safe.

The Legacy Bottleneck (Problem Space)

  • Sybase ASE and SQL Anywhere rely heavily on Transact-SQL (T-SQL) idioms that differ fundamentally from Oracle: ubiquitous `#temp` tables created on the fly inside stored procedures, implicit multi-result-set returns without `REF CURSOR` parameters, and page/row lock escalation.
  • Naive line-by-line conversion tools translate Sybase `#temp` tables into DDL `CREATE TABLE` calls inside Oracle procedures, causing catastrophic library cache latch contention.
  • Many Sybase databases are tightly coupled to legacy PowerBuilder or C++ (`CT-Lib` / `DB-Lib`) client applications that must be migrated in lockstep.

The Engineered Target Architecture

  • T-SQL / Watcom-SQL AST Analyzer & Transpiler: We parse `sysobjects`/`syscomments` exports to build a complete call graph of all Sybase stored procedures, triggers, rules, defaults, and user-defined datatypes.
  • Idiomatic Oracle 23ai Refactoring: Sybase `#temp` table anti-patterns are refactored into set-based Common Table Expressions (`WITH` clauses), Global Temporary Tables (GTTs), or Oracle Private Temporary Tables (`ORA$PTT_`). Implicit result sets use `DBMS_SQL.RETURN_RESULT` so client call signatures remain clean.
  • Concurrency & Isolation Model Normalization: Sybase's blocking read locks and `HOLDLOCK` hints are converted to Oracle's non-blocking Multi-Version Concurrency Control (MVCC), eliminating reader-writer deadlocks.
  • Automated Data Migration & Row-Hash Reconciliation: High-speed parallel extraction via `bcp` / Python Arrow pipelines into Oracle External Tables / SQL*Loader Direct Path, verified by column-level SHA-256 checksums.
Anonymized Production Proof · Verified Architecture Outcome

Paired frequently with our PowerBuilder-to-APEX modernizations, we have migrated multi-hundred-gigabyte Sybase ASE and SQL Anywhere databases containing thousands of T-SQL stored procedures into Oracle Database 19c/23ai, eliminating nightly batch deadlocks and cutting end-of-month close times by 70%.

Frequently Asked Technical & Licensing Questions

Direct answers to the architectural, licensing, and cutover questions raised by CIOs, VPs of Engineering, and Enterprise DBAs.

Should we convert our Sybase database and PowerBuilder front-end together or in phases?

We support both. We can migrate Sybase to Oracle 23ai first (repointing PowerBuilder's database profile from `SYC`/`ASE` to `ORA`) and then convert the PowerBuilder UI to Oracle APEX in Phase 2, or execute a combined vertical-slice cutover.

How do you handle Sybase's case-insensitive or padded string comparisons in Oracle?

Oracle Database 23ai supports native column-level and schema-level collation (`BINARY_CI` / `USING_NLS_COMP`), allowing exact parity with Sybase sort orders without wrapping indexed columns in `UPPER()` functions.

What is included in the downloadable PDF Solution Brief?

The PDF Solution Brief includes the 20-point Sybase-to-Oracle 23ai T-SQL translation guide, the `#temp` table refactoring decision tree, and our GoldenGate CDC cutover architecture.
