Chapter 5: Making Variables Dynamic
The first example searched for department information based on a numeric primary
key field called "Department_ID." Suppose, instead, that the primary key is a database

NAME="SelectedDepts"
VALUE="'Marketing'">
Marketing<BR>
<INPUT TYPE="checkbox"
NAME="SelectedDepts"
VALUE="'HR'">
HR<BR>
<INPUT TYPE="checkbox"
NAME="SelectedDepts"
VALUE="'Sales'">
Sales<BR>
<INPUT TYPE="checkbox"
NAME="SelectedDepts_required"
VALUE="You must select at least one organization.">

(#PreserveSingleQuotes(form.SelectedDepts)#)
The statement sent to the database would be:
SELECT *
FROM Departments
WHERE DepartmentName IN ('Marketing','Sales')
