SQL Order By Clause
Create a complex order by clause using the iif (immediate if) statement to change the Order By statement in a query based on user
There are many instances where you would like to sort a form or
report on different fields depending on a user's selection.
The following is an SQL example of an dynamic query Order By clause. This
example assumes you have a form ('F_Emp') with an Option Group ('Sort_Option')
with two possible choices. Option 1 is for sorting by employee name and
option 2 is for sorting by employee number. Variable sorting can
be accomplished in the Report however it is much more efficient to put this in
the SQL code.
Select M_Employees.Name, M_Employees.Emp_Number,
IIf(Forms!F_Emp!Sort_Option=1, M_Employees.Emp_Name, M_Employees.Emp_Number);
An alternative form of the Access Order By is the SQL order by
ordinal numbers. Ordinals are numbers that refer to the fields in the select
Example: ordinal 1 refers to M_Employees.Name, and ordinal 2
refers to M_Employees.Emp_Number. IIf(Forms!F_Emp!Sort_Option=1, 1, 2); This
form of the IIf clause is very useful when you need to nest IIf clauses
because of more than two sort choices.
The immediate if (IIF) statement can also be used to create dynamic where

clause works for this Access choose command example.
