There are two tables in Power BI, Table1 and Table2,
the data of Table1 comes from Database1 in Server1,
the data of Table2 comes from Database2 in Server2.
Table1 has columns: ID1, Value1
Table2 has columns: ID2, Value2
There is a one-to-one relationship between the two tables: ID1=ID2
But IDs in these two tables are not totally matched, for example:
Records in Table1:
ID1 Value1
1 A
2 B
3 C
4 D
Records in Table2:
ID2 Value2
1 A
3 C
5 E
Is it possible to create a new table Table3 in Power BI using SQL statement or other methods to get the diffrent records in Table1? All the records in Table3 come from Table1.
So Table3 should have following records:
2 B
4 D
Thanks.

Hi @j_w
You can do this in a number of places. In Power BI you can create new tables using this button
And just paste in the following DAX for your example
Table 3 = EXCEPT('Table 1','Table 2')
In Power Query you can simply merge (join) the tables with join type left anti (records in Table1 that don't exist in Table2).
This video illustrates how the code below is created.
let Source = Table.NestedJoin(Table1,{"ID1"},Table2,{"ID2"},"NewColumn",JoinKind.LeftAnti), #"Removed Columns" = Table.RemoveColumns(Source,{"NewColumn"}) in #"Removed Columns"

You can also do it in SQL but you will probably need a linked server between the two servers for the query to work.
There will also be a way you can do it in the Query Editor too @MarcelBeug will probably give you the best approach.
