Question

I have two tables. I need to join these tables using substring function. I tried something like this. But its not working…

Table01

ID  NameStreet
1   Julian Assange 100 Majestic street, Toronto
2   Brad Pit 200 Loaden Blvd, Toronto
3   Allen Sunderland 9, Unit 2, Janet Street, BC
4   Julian Assange 50 Majectic street, Toronto

Table02

ID Name
1  Julian Assange
2  Allen Sunderland 
3  Julian Assange

Current query (not working)

SELECT t1.* 
FROM Table01 t1 
JOIN Table02 t2 
ON t2.Name = SUBSTRING(t1.NameStreet, 0, CHARINDEX(t2.Name, t1.NameStreet))

Expecting Results:-

1   Julian Assange 100 Majestic street, Toronto
3   Allen Sunderland 9, Unit 2, Janet Street, BC
4   Julian Assange 50 Majectic street, Toronto

Answer 1

I think you want this in your query:

on t2.Name = LEFT(t1.NameStreet, (charindex(' ', t1.NameStreet)-1) )

EDIT

Does this work?

on t2.Name = LEFT(t1.NameStreet, Len(t2.Name) )
