The database has such a category ID.
How can I write the value of the second-level classification under 10? I write select * typetabe where family_id like "10%" in this way"
In this way, we can write all the categories. what I want is how to write it as long as it has a second-level classification.
That is, only the data I want to query.

1002 women's clothes
