Question

I joined two tables using following query. It is giving me duplicates because Table02 has duplicates. I need to prevent dupes.

Note:

1. I can’t change the order/sequence of the columns in my select statment.

2. I can’t use distinct on t1.NumberID.

   SELECT t1.NumberID, t1.Copies, t1.NameStreet
   FROM Table01 t1
   JOIN Table02 t2
   on t2.Name = LEFT(t1.NameStreet, Len(t2.Name)) order by t1.NumberID, t1.Namestreet

Table01

ID  NumberID    Copies      NameStreet
1   11111111    2           Julian Assange 100 Majestic street, Toronto
2   22222222    1           Brad Pit 200 Loaden Blvd, Toronto
3   11111111    0           Allen Sunderland 9, Unit 2, Janet Street, BC

Table02

ID  Name
1   Julian Assange
2   Allen Sunderland 
3   Julian Assange

Results:-

1   11111111    2           Julian Assange 100 Majestic street, Toronto
3   11111111    0           Allen Sunderland 9, Unit 2, Janet Street, BC
1   11111111    2           Julian Assange 100 Majestic street, Toronto

Expected Results:-

1   11111111    2           Julian Assange 100 Majestic street, Toronto
3   11111111    0           Allen Sunderland 9, Unit 2, Janet Street, BC

Answer 1

Add this to the end of the query:

GROUP BY  t1.NumberID, t1.Copies, t1.NameStreet
