In Access, we can’t use CASE statement.
Alternatively, we can use Switch
statement.
Usage
The above code was written with Switch
as follows.
It was said that Access employs Switch
because of compatibility with VBA
, but I don’t know actual reason.
Use iif
You can also use Iif
. The following code leads same result.
Use Choose
It is a choice to use Choose
, in some cases.
index
に整数を入れると、index = 1
なら a
が、 index = 2
なら b
が返ります。 整数でない場合は、一番近い整数に丸められます。 If index
is less than 1, Null
is returned.
