I have data that I've imported into a table in the AS/400 (DB2) from SQL 2000. I need to update a column in a table that previously existed on the AS/400 with the new data I've imported from SQL 2000.
Any idea how to do an update that contains an inner join in DB2?> >
>Here is the problem:>
>Table1.Column2 (FFIITMAP. FFIHGTH) all records are blank
and I need to update them with the values from Table2.Column2 (cubiscan.CFFIHGTH)
where Table1.Column1(FFIITMAP.FFIITMN) = Table2.Column1(cubiscan.CFFIITMN)>
>This is how I would do it within SQL 2000

>Update idsdemo.FFIITMAP
set FFIHGTH = CFFIHGTH
From idsdemo.FFIITMAP
inner join idsdemo.cubiscan on ltrim(rtrim(idsdemo.cubiscan.CFFIITMN)) = ltrim(rtrim(idsdemo.FFIITMAP.FFIITMN))>

Update idsdemo.FFIITMAP
inner join idsdemo.cubiscan on ltrim(rtrim(idsdemo.cubiscan.CFFIITMN)) = ltrim(rtrim(idsdemo.FFIITMAP.FFIITMN))
set FFIHGTH = CFFIHGTH >
>--DB2 Says it returns more than one row
Update idsdemo.FFIITMAP
set FFIHGTH =
(select CFFIHGTH from idsdemo.cubiscan
inner join idsdemo.FFIITMAP on ltrim(rtrim(idsdemo.FFIITMAP.FFIITMN)) = ltrim(rtrim(idsdemo.cubiscan.CFFIITMN))
)>

I had noticed I posted the original question under a category that was not consistent with my question so I posted under a category that made more sense, however I didn't know how to remove the original posting. Sorry...
