Query in pl/sql oracle

Question

Hi All!
I want to write following type of query in PL/SQL
How can I write one which will work.
<B>
SELECT count(1) INTO v_count2 from TRJ_TRAN_REJ_T a and PEU_PUR_ENRL_UNT_T b
where a.TRJ_CVRG_PER_DATE IN (b.PEU_EFF_DATE AND b.PEU_END_DATE) AND
a.purik = b.purik AND a.peuik = b.peuik
<B>
Above query is not working correctly. Any changes?? DATE stored in database is like 01/01/2001
v_count2 is NUMBER variable declared in PL?SQL.

You don't need to use a PL/SQL, a simple SQL will suffice. I guess you could write it as a function?
I think your SQL was wrong so I took the liberty of fixing it for you. You seperate tables with commas in a FROM clause, not AND.
Anyway, on the lines of a SQL Statement you can do the following.
SELECT     count(1) AS mycount
FROM     TRJ_TRAN_REJ_T a,
     PEU_PUR_ENRL_UNT_T b
WHERE     a.TRJ_CVRG_PER_DATE IN (b.PEU_EFF_DATE AND b.PEU_END_DATE)
AND     a.purik = b.purik
AND     a.peuik = b.peuik
Connection conn = DriverManager.getConnection(URL, username, password);
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery( your sql);
while ( rs.next() )
     int mycount = rs.getInt("mycount");
