 Subject: Outer join in SQL server - A very simple question 
 
 
 Sorry for the SQL Server post, working on SQL Server for the 
 first time, and
 this list is my only resource as of now. I'm reading the SQL 
 Server join
 syntax and trying it myself. Meanwhile, If i can get some 
 expert help, it

 I'm simplifying the problem with the help of these test tables.
 
 CREATE TABLE t1(A VARCHAR(10), A1 VARCHAR(10), A2 VARCHAR(10));
 CREATE TABLE t2(B VARCHAR(10), B1 VARCHAR(10));
 CREATE TABLE t3(C VARCHAR(10), C1 VARCHAR(10));
 CREATE TABLE t4(D VARCHAR(10), D1 VARCHAR(10));
 
 INSERT INTO t1 VALUES ('A', 'AA', '');
 INSERT INTO t1 VALUES (null, '', '');
 
 INSERT INTO t2 VALUES ('A', 'BB');
 
 INSERT INTO t3 VALUES ('A', 'CC');
 
 INSERT INTO t4 VALUES ('A', 'DD');
 
 Table t1 refers to t2(through a) and t4(through a2) directly 
 and t2 refers to
 t3(through b). 
 
 I want to join t1 to t2, t3, t4 and retrieve all the rows inside t1
 irrespective of whether the value is there in the other tables or
 not(outer-join of course)
 
 I wrote this query in Oracle and it works
 
 SQL SELECT a1, b1, c1, d1

 I substituted the + with the * to use it in SQL Server

 query look like this:

 WHERE  t1.a =* t2.b
 ANDt2.b =* t3.c
 ANDt1.a2 = t4.d
 
 But it fails with the error:
 
 The table 't1' is an inner member of an outer-join clause. 
 This is not
 allowed if the table also participates in a regular join clause.
 
 How to overcome this? Or is the query wrong?

RE: Outer join in SQL server - A very simple question

2003-06-25 Thread Pardee, Roy E 
I think this does what you want:

   select a1, b1, c1, d1
   from  t1 left join t2 on t1.a = t2.b
 left join t3 on t2.b = t3.c 
 left join t4 on t1.a2 = t4.d ;

NB--I don't think this is necessarily a mssql question--oracle 9i (at least)
supports the same ANSI-92 standard join syntax.  See, e.g.,
http://www.nyoug.org/9ijoin.pdf

The way I remember whether to do a left or a right outer join is I picture
an arrow pointing to the table I want 'preserved' (that is, the one I want
to see rows from even where there's no corresponding row in the other
table).

HTH,

RE: Outer join in SQL server - A very simple question

2003-06-25 Thread Rudy Zung 

IIRC, the *= from Sybase and SQLServer is placed on the
opposite side of Oracle's (+) for the same affect.
i.e.
ORACLE:
   select a.*,
  b.*
  from a,
   b
  where a.x(+) = b.x
Sybase/SQLServer:
   select a.*,
  b.*
  from a,
   b
  where a.x =* b.x
The above 2 queries are equivalent; you can't just
replace the (+) with a *; you will also have to move
it to the other side of the equal sign.

   3  WHERE  t1.a = t2.b(+)
   4  ANDt2.b = t3.c(+)
   5  ANDt1.a2 = t4.d
   6  /
 
 A1 B1 C1 D1
 -- -- -- --
 AA BB CC DD

 I substituted the + with the * to use it in SQL Server which made
 my
 query look like this:
 
 SELECT a1, b1, c1, d1
 FROM   t1, t2, t3, t4
 WHERE  t1.a =* t2.b
 ANDt2.b =* t3.c
 ANDt1.a2 = t4.d
 
 But it fails with the error:
 
 The table 't1' is an inner member of an outer-join clause. This is
 not
 allowed if the table also participates in a regular join clause.
 
 How to overcome this? Or is the query wrong?
 
 Regards
 Naveen
