IIF STATEMENT IN UPDATE QUERY

[Guest]

Hello,

I'm trying write an update query that evaluates 3 critiera. I want it to
evaluate the critieria in one field [PP] and then update the values in the
[CIV TYP] field. My logic is as follows

If the PP Field is like C*, K* D*, or A*, then I want the CIV TYP field to
fill with 202.
If the PP Field is like X*, then fill CIV TYP field with 110
If the PP Field is like B*, then fill CIV TYP field with 206

for all else leave as is.

So this is what i've come up with from researching the newsgroups, but it
receive a syntax error.

UPDATE [CURRENT DCPDS]

SET [CURRENT DCPDS].[CIV TYP] = IIF(([CURRENT DCPDS].PP) Like "C*" Or
([CURRENT DCPDS].PP) Like "K*" Or ([CURRENT DCPDS].PP) Like "D*" Or ([CURRENT
DCPDS].PP) Like "A*"),"202")

SET [CURRENT DCPDS].[CIV TYP] = IIF(([CURRENT DCPDS].PP) Like "X*", "110")

SET [CURRENT DCPDS].[CIV TYP] = IIF(([CURRENT DCPDS].PP) Like "B*" ,"206")

Try this:

UPDATE [CURRENT DCPDS]

SET [CIV TYP] =
Switch([PP] Like "C*"
Or [PP] Like "K*"
Or [PP] Like "D*"
Or [PP] Like "A*", "202",
[PP] Like "X*", "110",
[PP] Like "B*", "206")

WHERE [PP] Like "C*"
Or [PP] Like "K*"
Or [PP] Like "D*"
Or [PP] Like "A*"
Or [PP] Like "X*"
OR [PP] Like "B*"

The Switch() function is a VBA function. Sea the VBA Help article
"Switch Function" for more info.

It is probably in your better interest to utilize several queries to perform
all of the different updates, if for no other purpose than debugging or
rollback. For example, if you have a logic error, attempting to locate it
would be near impossible with all of those IIF()'s triggering independently.

Create the 3 queries, add them to a macro, then call the macro when needed.
