🔹How to Migration from SQLite to Oracle
Migrating from SQLite to Oracle typically involves converting your data to text first and then loading it into Oracle using a native utility.
For example:
✅ Step 1: Export your SQLite data to CSV files.
✅ Step 2: Use SQL*Loader to import these CSV files into your Oracle database.
🔹Using ODBC and Heterogeneous Services
If you can connect to SQLite through ODBC, you can leverage Oracle’s Heterogeneous Services to create a database link.
This lets you query SQLite directly from Oracle — useful for migration or interoperability.
🔹Open-Source Library (Kansas State University)
Some students from Kansas State University have implemented an open-source library of Oracle-compatible SQLite functions.
This can help ease migration by adding PL/SQL-like functionality directly into SQLite.
🔹StepSqlite by Metatranz LLC
The StepSqlite product from Metatranz LLC is a PL/SQL compiler for SQLite.
It supports a subset of PL/SQL, allowing you to reuse code or develop in parallel with both Oracle and SQLite.
SQLite to Oracle
Data must typically be converted to text and then loaded using each database’s native loader utility. For example, use SQL*Loader to load the text files into an Oracle database. If you can make SQLite accessible via ODBC, you should also be able to use Oracle’s Heterogeneous Service to connect to it via a DB link.
An open-source library of Oracle-compatible SQLite functions has been written by students from the Kansas State University. Functions for other DBMS products have also been written.
