Migrates Oracle PL/SQL stored procedures to PostgreSQL PL/pgSQL. Translates Oracle-specific syntax, preserves method signatures and type-anchored parameters, leverages orafce where appropriate, and applies COLLATE "C" for Oracle-compatible text sorting. Use when converting Oracle stored procedures or functions to PostgreSQL equivalents during a database migration.

Migrating Stored Procedures from Oracle to PostgreSQL
Translate Oracle PL/SQL stored procedures and functions to PostgreSQL PL/pgSQL equivalents.
Workflow
Progress:
- [ ] Step 1: Read the Oracle source procedure
- [ ] Step 2: Translate to PostgreSQL PL/pgSQL
- [ ] Step 3: Write the migrated procedure to Postgres output directory
Step 1: Read the Oracle source procedure
Read the Oracle stored procedure from .github/oracle-to-postgres-migration/DDL/Oracle/Procedures and Functions/. Consult the Oracle table/view definitions at .github/oracle-to-postgres-migration/DDL/Oracle/Tables and Views/ for type resolution.
Step 2: Translate to PostgreSQL PL/pgSQL
Apply these translation rules:
- Translate all Oracle-specific syntax to PostgreSQL equivalents.
- Preserve original functionality and control flow logic.
- Keep type-anchored input parameters (e.g.,
PARAM_NAME IN table_name.column_name%TYPE). - Use explicit types (
NUMERIC,VARCHAR,INTEGER) for output parameters passed to other procedures — do not type-anchor these. - Do not alter method signatures.
- Do not prefix object names with schema names unless already present in the Oracle source.
- Leave exception handling and rollback logic unchanged.
- Do not generate
COMMENTorGRANTstatements. - Use
COLLATE "C"when ordering by text fields for Oracle-compatible sorting. - Leverage the
orafceextension when it improves clarity or fidelity.
Consult the PostgreSQL table/view definitions at .github/oracle-to-postgres-migration/DDL/Postgres/Tables and Views/ for target schema details.
Step 3: Write the migrated procedure to Postgres output directory
Place each migrated procedure in its own file under .github/oracle-to-postgres-migration/DDL/Postgres/Procedures and Functions/{PACKAGE_NAME_IF_APPLICABLE}/. One procedure per file.
