How can I prioritize specific rows when ordering MySQL results?
MySQL result sorting and priority setting
This article describes how to prioritize specific rows in MySQL result sorting.
Method 1: Complete sorting
If you need to sort based on all possible values in a field, regardless of their order:
SELECT id, name, priority FROM mytable ORDER BY FIELD(name, "core", "board", "other")
Method 2: Prioritize "core", the order of other values does not matter
If you need to prioritize "core" and ignore the order of other values:
SELECT id, name, priority FROM mytable ORDER BY FIELD(name, "core") DESC
Method 3: Prioritize "core", then sort in regular order
If you need to prioritize "core", then sort in the usual order of the other values in the field:
SELECT id, name, priority FROM mytable ORDER BY FIELD(name, "core") DESC, priority
Note:
- This method may only work with MySQL.
- FIELD() function returns the 1-based index of the value. If the value is not in the provided list, it will return zero, so DESC is usually required.
