Hi All,I am stuck in a situation where I am trying to use CROSS JOIN.But this not solving my problem at all.I am using example to show my problem.Declare @a table( a int)INSERT into @a values (1)Declare @b table( b int)INSERT into @b VALUEs(2)Declare @c table( c int)INSERT into @c VALUEs(3)SELECT t1.a,t2.b,t3.c from @a t1 CROSS JOIN @b t2 CROSS JOIN @c t3Above script gives me correct information like a b c1 2 3But the Problem is if any of the table is blank it does not return any thing for exampleDeclare @a table( a int)INSERT into @a values (1)Declare @b table( b int)--INSERT into @b VALUEs(2)Declare @c table( c int)INSERT into @c VALUEs(3)SELECT t1.a,t2.b,t3.c from @a t1 CROSS JOIN @b t2 CROSS JOIN @c t3Table @b is empty and this Select query gives nothing.How can I fix this even after any of the table is blankI should get the column with NULL or blank value. Vijay is here to learn something from you guys. |

This is what CROSS JOIN is meant to do.It is difficult to tell, but maybe you want a FULL JOIN:SELECT t1.a,t2.b,t3.cfrom @a t1 FULL JOIN @b t2 ON 1=1 FULL JOIN @c t3 ON 1=1 |
