I’m working on a Spring Boot application that connects to a Solr database. I want to switch from using Solr syntax to regular SQL statements. Basic queries work fine for me, like select * from productData, but I’m having trouble with more complex operations involving WHERE conditions and column selection.
I need help converting this Solr search syntax:
productId:456 OR categoryName:"Electronics"
Into proper SQL format like this:
select productId, cost from productData where productId=456 or categoryName="Electronics"
Can this conversion be done directly, or should I stick with translating my SQL queries into Solr format instead? I’m currently using Solr version 6.1.0 for this project.
yeah, solr’s a search engine, not a sql db. you can’t directly run sql against it. to use sql, you’d have to migrate data to a traditional db like mysql or postgres. otherwise, just stick with solr’s syntax, it’s made for that.
The conversion you’re attempting is not possible because Solr and SQL operate on fundamentally different architectures. Solr is a document-based search platform built on Lucene, while SQL is designed for relational databases. Your Solr syntax productId:456 OR categoryName:"Electronics" cannot be directly converted to run against Solr using SQL commands. However, Solr does offer SQL-like functionality through its SQL interface introduced in later versions, though this still translates to Solr queries internally. Given that you’re on version 6.1.0, I would recommend embracing Solr’s native query syntax rather than fighting against its design. The performance benefits and search capabilities you gain from Solr’s approach typically outweigh the learning curve, especially for applications requiring full-text search or faceted navigation.
wait, are you trying to query solr using actual sql syntax? that’s kinda backwards since solr uses its own query parser. what made you want to switch from solr syntax to sql - is it just familiarity or some specific requirement? curious about your usecase here!
