Using tuples in ORACLE IN clause and a condition for one element in the tuple

Question

I have seen many questions here for using tuples in the IN clause. My situation is a little different from the others. General usage of tuples in IN clause will look as below

    Select * from MY_TABLE
    where (id,name,date) IN ((1,'new','10-JUL-13'),(2, 'old','09-JUN-13'))

Considering the above query, my requirement is to retrieve the records with id and name values along with date in a particular range. lets say

    effectiveDate <= date <= termDate  

I'm using ORACLE database and MyBatis ORM. I'll get data as a list of objects, so when I use mybatis I can use a foreach/for loop to populate the tuples, but when I want to use condition for one of those values from the object.

When I use Mybatis for one value read from a list, the where clause as below

    <where>
        and (id,name) IN
   <foreach item="object" collection="data" open="(" separator=","close=")">
    (#{object.id},#{object.name})
   </foreach>
    </where>

I have to include the condition in the loop as well.

Waiting for the expert advice. Thanks in advance.

Answer 1

Are you looking for something like this?

select *
from MY_TABLE
where (id, name) in ((1,'new'), (2, 'old')) and
      date between effectiveDate and termDate

This looks for the pairs in a list and then checks for the dates between a range of dates.

EDIT:

I think you want to break this into multiple clauses, one for each set of values:

where (id = 1 and name = 'new' and date between eff1 and term1) or
      (id = 2 and name = 'old' and date between eff2 and term2) or
      . . .

Answer 2

The above solution for my question is rewritten below for Mybatis users

    <where>
    <foreach item="object" collection="data" separator="OR">
      (id = #{object.id} AND name = #{object.name} AND (effDt < #{object.date} < termDt))
    </foreach>
    </where>

There won't be a big performance difference when you use either IN or OR to separate the data/conditions in the WHERE clause.
