Hi,
I have to write one sql query to see the policy number and plan id available in the DB2 table.Each policy number has the separate plan id.
For example:
Policy plan
a 1
b 4
c 6
d 5
e 1
select policy,plan where policy,plan=(a,1)(?) -
i want the list of policy to be checked in the single query. |

values ((a,1),(b,4)) isn't supported (yet) on z/OS
the simpliest way to do it is with the OR clauses like guptae said
for performance reasons you could try
| Code: |
with input (pol,plan) as (
select 'a',1 from sysibm.sysdummy1
union all
select 'b',4 from sysibm.sysdummy1
union all
...
)
select a.pol, a.plan from table1 A, input
where (input.pol,input.plan) = (a.pol,a.plan) |
or the old fashioned way :
| Code: |
select a.pol, a.plan from table1 A where pol = 'a' and plan =1
union all
select a.pol, a.plan from table1 A where pol = 'b' and plan =4
union all
