I have a SQL database that I have recently added a new field. To populate the field I need to create a statement to

for a [Location Code] = "HOI" and [Category] <> "Monitor" then [pcname]will be "C" = [Asset tag]

I have about 10 such statements so IIF won't work. I'm new to SQL.

Can someone please provide some help with the syntax

Your question is not fully clear, but maybe something like this?


update table
set [Asset tag]= case
                  when [Location Code] = 'HOI' and [Category] <> 'Monitor' then [pcname]
                  when ... then ...
                  else ...
                 end

No, you're never too old to Yak'n'Roll if you're too young to die.

[code]
update table
set [pcname]= case
when [Location Code] = 'HOI' and [Category] <> 'Monitor' then 'C'+[Asset tag] -- if [Asset tag] is numeric: use 'C' + convert(varchar(255),[Asset tag])
when ... then ...
else ...
end

[/code]
I don't know much about [Asset tag]

No, you're never too old to Yak'n'Roll if you're too young to die.
