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 COMMENT or GRANT statements.
• Use COLLATE "C" when ordering by text fields for Oracle-compatible sorting.
• Leverage the orafce extension 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.
