I wish this helpful for you I believe you'll want your update statement changed to look like this:

FROM dbo.Table_B AS b
INNER JOIN Inserted AS i ON b.EmpId = i.EmpId

it fixes the issue One way to do it is to simply loop over all the directories you already have, and in each bottom-level subdirectory create the new subdirectory and move the files:

  cd "$d" &&
  printf '%.4s\0' * | uniq -z | 
  xargs -0 bash -c 'for prefix do
                      mkdir -p "$s" && mv "$prefix"* "$s"
                    done' _
) done
( cd "$d" && ...; )
printf '%.4s\0' * | uniq -z | xargs -0 ...

To fix this issue This query is very efficient if SQLite can use an index for this lookup.
LIKE is case insensitive, so
