Hi,

I have the following situation:

3 tables:

Table: variable_value
variable_id int(11)
company_id int(11)
variable_value varchar(255)

Table: variable
variable_id int(11)
variable_name varchar(255)

Table: company
company_id int(11)
company_name varchar(255)

I store variables in the variable tables and companies in the company
table. I want to assign a different value to each variable for each
company. Now I need a select that will show me all variables of a
company if they are in the variable_value table yet or not.

I came this far, but this isn't what I need, since it does not show all
variables:
Select variable_value, variable.variable_id, variable_name,
company_name FROM company
LEFT JOIN variable_value ON variable_value.company_id =
company.company_id
LEFT JOIN variable ON variable.variable_id = variable_value.variable_id
WHERE company_id = ??

Anyone got an idea?

Thx alot
