I’m looking for a database tool that can help catch SQL mistakes before they cause problems. Our operations team writes complex SELECT queries all day but sometimes makes errors when working quickly.
The main issues we face are:
- Queries that run too long and slow down our test database
- Results that look correct but are actually wrong due to missing joins or other logic errors
For example, if someone writes:
SELECT p.product_name, s.store_name
FROM products p, stores s
WHERE p.price > 100;
I want a tool that would warn “This creates a cartesian product - did you forget a JOIN condition?”
We use MySQL and need something that can spot obvious problems like missing WHERE clauses, incorrect joins, or other common mistakes. The queries are read-only on a copy database, but catching errors early would save time and prevent wrong results.
Does anyone know of SQL editors or validation tools that provide this kind of smart error checking?
