Question

I am trying to run a query that selects values from a table using a WHERE clause , the query only returns the rows where all of the conditions have values, hoe do I go about returning the values that are also null?

     Language Table                            Students Table
 ID    Language                        ID      Student      LanguageID
  1     English                         1        Joe
  2     Spanish                         2        Mike          1

Running a query such as

Select student.ID , Student.Student , Language.language 
FROM 
    Students, Language 
WHERE 
    student.LanguageID = Language.id 

The query only returns a single row for student mike I would like to return all student even if the language setting is null.

Answer 1

You want something like this:

select
  student.id, student.student, language.language
from
  student left join language
      on student.languageid = language.languageid
