Question

I want to make a select query with an and condition.

dept, divi, comp as string

Deparment = dept
Division = divi
company = comp

Tried this query:

Select *
from table
where
  department = '" & dept & "'
  and division = '" & divi & "'
  and Company = '" & comp & "'

The above query is working if the dept, divi, comp values are available.

Conditions

If user select department only, it should display all value for that selected department only
If user select department and company means, it should display selected company and selected department for that company
If user select department, division and company means, it should display selected company, selected division for that company, selected department for that division.

How to make this select query?

Answer 1

I think this may help you:

Select *
from table
where
    (@dept = NULL OR department = @dept)
    and (@div = NULL OR division  = @div)
    and (@comp = NULL OR Company = @comp)
