Hello, i don't have anything fancy here. Most will be bored but I just wanted to make sure that what I have will not create problems. I have four tables that are linked by a case number. Is this SQL ok?

select Distinct * from Table1 A, Table2 B, Table3 C, Table4 D
where A.Casenum = B.Casenum
and B.Casenum = C.Casenum
and C.Casenum = D.Casenum

Order by A.Casenum

Thanks in advance!

Have you tested it? Why aren't you using proper JOIN syntax?

well you might if you're not ANSI

And why DISTINCT? Don't cide if you don't need it

Same with Order by

Always format your code

and Always upper case SQL commands


	 SELECT * 
	   FROM Table1 A
     INNER JOIN Table2 B
	     ON A.Casenum = B.Casenum 
     INNER JOIN Table3 C
	     ON B.Casenum = C.Casenum
     INNER JOIN Table4 D
	     ON C.Casenum = D.Casenum
       ORDER BY A.Casenum

That's what I was wondering....if I needed the inner join or not. I did test this and it worked fine though. I will take off the distinct.

Thank you so much for the responses!!
