Applying joins conditionally in SQL Server -

-

i have set of records, have select records set have theeir id in either of 2 tables.

suppose have table1 contains

id  name ---------- 1   name1 2   name2

now need select records table 1 have either id in table2 or in table3

i trying apply or operator witin inner join like:

select *  table1  inner join table2 on table2.id = table1.id or inner join table3 on table3.id = table1.id.

is possible? best method approach this? not able use

if exist(select 1 table2 id=table1.id) select table1

could me on this?

i inclined use exists:

select t1.* table1 t1 exists (select 1 table2 t2 t2.id = t1.id) or       exists (select 1 table3 t3 t3.id = t1.id) ;

the advantage using exists (or in) on join involves duplicate rows. if table2 or table3 have multiple rows given id, version using join produce multiple rows in result set.
