  I have two tables.

  To make it simple, the table dutyrostershift has two relewant fields field "ID" and MTID_ID

  The table mTidClockInClockOut has two relevant fields External_ID and MTID_ID

  External_ID in mTidClockinout equals ID in ID in dutyrostershift.

  I want to update dutyrostershift.MTID_ID with mTidClockInOut-mtid_ID where dbo.dutyrostershift.ID = dbo.mTidClockInOutRecord.externalId

  I can find the relevant fields to update with

  select dutyrostershift.mtid_id from dutyrostershift

  join mTidClockInOutRecord ON mTidClockInOutRecord.externalid = dutyrostershift.ID

  WHERE dbo.dutyrostershift.ID = dbo.mTidClockInOutRecord.externalId

  But how to update is the question.

  please help!

  Best regards

  Pretty simple, if you can select, you can update.

  Generic code sample

  UPDATE

  A

  SET

  A.foo = B.bar

  FROM

  TableA A

  JOIN

  TableB B ON A.col1 = B.colx

  WHERE

  ........

  Thanks!

  And good to have it as a 'Generic'.
