如果列值为 2_apples 或 final_chapter 我如何匹配包含下划线 "_" 的值？
我试过:
SELECT DISTINCT brand FROM `items` WHERE brand like '%\\_'
SELECT DISTINCT brand FROM `items` WHERE brand like '_'
SELECT DISTINCT brand FROM `items` WHERE brand like '%_%'
SELECT DISTINCT brand FROM `items` WHERE brand like LIKE '\_'
它要么显示所有结果，要么不显示。有什么建议么？
