I have very limited Microsoft SQL experience but need an efficient way to do this.

Table1
field1 field2 field3

Table2
field1 field2 field4

I want to work through table1 - first to last
check table2 for match on table1.field1 = table2.field1 and table2.field4 = 'Y'
if no match
      create new record in table2
if match and table1.field2 <> table2.field2
      update table2.field4
      create new record in table2

      
      Any help appreciated
