How to Ensure Case-Insensitive LIKE Queries Work Across MySQL and Postgres?

Maintaining Case Insensitive Queries Across MySQL and Postgres

Your predicament stems from the incompatible case-sensitivity of LIKE queries between MySQL and Postgres. While MySQL uses LIKE, Postgres employs iLike for case-insensitive comparisons. This incompatibility poses a challenge when deploying code from a MySQL development environment to a Postgres production environment.

The Dilemma:

• Using LIKE in Postgres results in case-insensitive behavior, which differs from MySQL's default.
• Using iLike in MySQL is not supported, leading to potential errors.

The Ideal Solution:

The "correct" way to solve this issue is to ensure the development and production environments use the same database engine. This eliminates the need for compatibility workarounds and prevents any potential inconsistencies or bugs.

Unwise Alternatives:

However, this may not always be feasible. In such cases, you could resort to writing separate LIKE/iLike statements depending on the database being used. However, this approach is not recommended as it introduces additional complexity and potential for errors.

Conclusion:**

While compatibility issues between databases can be frustrating, it is crucial to recognize that using different software stacks for development and production can lead to unforeseen problems. Always strive to maintain a consistent environment to ensure seamless operation and accurate testing.
