SQL

  UPDATE mbTbl
  SET mbTbl.Status=erpTbl.[Status],mbTbl.ModifiedDate=GETDATE(),erpTbl.IsSent=1
  from openquery (LINKED, 'select * from mobileapp.student_status_tbl') as mbTbl
  INNER JOIN
  OPENROWSET('SQLNCLI',
'server=xxx.xx.x.xxxxx;Uid=xxxxx;Pwd=xxxx123;
database=[yd];
Persist Security Info=False',
'select * from AlahlidbN.dbo.mstudentstatus') as erpTbl
  ON erpTbl.Student_id=mbTbl.Student_PId
  WHERE erpTbl.IsSent=0  and erpTbl.Stage=mbTbl.Stage_

What I have tried:

gave error like that

The multi-part identifier "erpTbl.IsSent" could not be bound.

I don't believe you can update fields from more than one table at the same time like this.

You need 2 update statements. Possibly create a temp table to store the ids that you need to work with but you can't update 2 tables with a single update statement.

I'd suggest to use linked server[^]. Then you'll be able to act with databases as on single server ;)

It actually looks like they are trying to update fields in 2 different tables with the same update statement. Can't do that as far as I know.

mbTbl.Status=erpTbl.[Status],...,erpTbl.IsSent=1

yes i m trying to update two table fields using single query

So, you can't update 2 tables in a single sql query. ZurdoDev is right.

As mentioned in comments, the update statement will only update 1 table at a time. Hence

SQL

Update table SET field = value

You will need to do 2 different update statements.

One option is to store in a temp table all the ids of the fields that you need to touch so that you can do 2 updates and make sure you get all of the relevant fields. However, depending on your logic, a temp table may not be required.

Also, you should likely do this in a transaction so that if one update fails, both are rolled back.
