Using Pseudo Columns with a Linked Server

If you use 4 part SQL when attempting to query a pseudo column, you will get an error. For example, in this query ROWID is a pseudo column:

SELECT ROWID, ORDER_ID FROM MYLINKEDSERVER..SYSTEM.ORDERS

Msg 207, Level 16, State 1, Line 4
Invalid column name 'ROWID'.

With 4 part SQL, you can only query physical columns in a linked server table, not pseudo columns.

To work around this, use the OPENQUERY function instead. For example:

SELECT * FROM OPENQUERY(MYLINKEDSERVER,'SELECT ROWID, ORDER_ID FROM ORDERS')
