SQL help with joining tables

Question

I have 3 sql tables that I am trying to write a query on.
vAD1 ia the main table. This is linked with the other table using field ID1

When I run the following I get one row from the vQR3 table

Select vAD1.,vQR3. from vAD1
join vQR3 on vAD1.ID1 = vQR3.ID1
where vAD1.ID1= 'C001'

However, when I link vPRE table, my data gets duplicated. For every row in vPRE table, data in vQR3 is get duplicated. Is there away to remove the duplicates. I have about 6 tables to link. Then I get the data in table 2, 3, 4 and 5 duplicated in my final query. I am only including 3 tables here to see whether I could have the duplicates removed in this one.

Select vAD1.,vQR3., vPRE.* from vAD1
join vQR3 on vAD1.ID1 = vQR3.ID1
join vPRE on vAD1.ID1 =vPRE.ID1
where vAD1.ID1= 'C001'

CREATE TABLE vAD1(
       [ID1] [varchar](30) NULL,[VID1] [varchar](30) NULL, [F1] [varchar](13) NOT NULL, inv_date [datetime] NULL, LOCATION [varchar](15) NULL,

) 

INSERT INTO vAD1 values ('C001','AB111','AAA','08/15/2020','1234')

Answer 2

SELECT DISTINCT vAD1.*, vQR3.*, vPRE.* 
FROM vAD1
JOIN vQR3 ON vAD1.ID1 = vQR3.ID1
JOIN vPRE ON vAD1.ID1 = vPRE.ID1
WHERE vAD1.ID1 = 'C001';

Answer 3

Thanks for the response. Much appreciated. That was not the result I was expecting.
For ID "C001"
There is 1 record in vQR3
There are 5 records in vPRE
I need to give counts on certain fields. For example, if I were to give a count on vQR3.QR field in my report, it will show as 4, but the actual count for C001 is 1.
I am expecting the following output. Not sure whether this is possible.

Answer 4

Thanks. Much appreciated. It works. I am going to add the rest of the tables and see how it works.
