Query in 2 tables - JOIN

Question

I am struggling in MySQL. I have 2 Tables, one Table with all the data and 1 table with generic information about a node.

dataTable

ID
Name

nodeTable

ID
Address

Now I have the Address and I want to build a query in which the Name is returned. I probably should use a JOIN but the last time I worked with MySQL goes way back.

Thanks in advance

Please share some sample data and the result you're trying to get for it — Mureinik, Oct 22 '17 at 18:58

Does the below code fulfill your needs?

select Name 
  from dataTable, nodeTable 
 where dataTable.ID = nodeTable.ID
   and Address = 'Rathausstrasse'

Don't encourage a old JOIN style that is over 25 years old use proper INNER JOIN syntax – Raymond Nijland Oct 22 '17 at 19:15
its just the style - it doesn't make a difference performance wise - the query optimizer is smart enough nowadays... – inxoy Oct 22 '17 at 19:17
the newer INNER JOIN syntax is easier to read and understand,, performance wise indeed makes no difference – Raymond Nijland Oct 22 '17 at 19:22
