MySQL条件查询：筛选enable为true且min、max在2-30间的数据行

Alright, let's tackle this filtering problem. Here's how to get the exact result you're looking for:

First, let's lay out your original dataset clearly:

Key Filtering Criteria #

We need to apply two layers of checks:

• First, ignore any rows where enable is false—these are excluded entirely.
• For rows where enable is true, we only keep those where both min and max fall within the range of 2 to 30 (inclusive).

Applying the Filters to Each Row #

Let's go through each entry to see which ones qualify:

• Row 1: enable is true, min=4 (fits 2-30), max=10 (fits 2-30) → kept
• Row 2: enable is false → excluded
• Row 3: enable is true, but max=45 is outside the 2-30 range → excluded

Final Filtered Result #

If you're using a tool like SQL to automate this, here's a sample query that would give you the above result:

SELECT id, enable, min, max
FROM your_table
WHERE enable = true
  AND min BETWEEN 2 AND 30
  AND max BETWEEN 2 AND 30;
