Question

I’m trying to determine a way to query data from a MySQL database and, if there is already a duplicate of that data, to skip it and move to the next one.

What I’m trying to accomplish is to pull a list of department’s from a database and list them once for ex:

MySQL table
1  Accounting
2  Manufacturing
3  Manufacturing
4  HR

I want it to print:

Accounting, Manufacturing, HR

You can use GROUP BY:

SELECT field_name FROM table_name GROUP BY field_name

Or DISTINCT:

SELECT DISTINCT field_name FROM table_name
