Question

I’m doing an order on all fields of a table (depending on the user’s choice), however one column of that table contains a category (stored as an abbreviation) and those abbreviations are defined in a second table. How can I sort by category name? Example of the table structures below:

Table 1

title | amount | category_abbreviation

Table 2 -> for category

category_name | category_abbreviation

Answer 1

Just join the tables and order on a field from the second table.

SELECT * from table1 
INNER JOIN table2
ON table1.category_abbreviation = table2.category_abbreviation
ORDER BY table2.category_name
