Select Query by Pair of fields using an in clause

Question

I have a table called players as follows:

First_Id    Second_Id     Name 1           1             Durant 2           1             Kobe 1           2             Lebron 2           2             Dwight 1           3             Dirk 

I wish to write a select statement on this table to retrieve all rows whose first ids and second ids match a bunch of specified first and second ids.

So for example, I wish to select all rows whose first and second ids are as follows: (1,1), (1,2) and (1,3). This would retreive the following 3 rows:

First_Id    Second_Id    Name 1           1            Durant 1           2            Lebron 1           3            Dirk 

Is it possible to write a select query in a manner such as:

SELECT *  FROM PLAYERS WHERE (First_Id, Second_Id) IN ((1,1), (1,2) and (1,3))? 

If there is a way to write the SQL similar to the above I would like to know. Is there a way to specify values for an IN clause that represents multiple rows as illustrated.

I'm using DB2.

Answer 1

This works on my DB2 (version 9.7 on Linux/Unix/Windows) by using this syntax:

SELECT * FROM PLAYERS WHERE (First_Id, Second_Id) IN (VALUES (1,1), (1,2), (1,3)) 

This syntax won't work on DB2 on the Mainframe (at least in version 9.1) because you can't substitute a sub-select with a VALUES expression. This syntax will work:

SELECT * FROM PLAYERS WHERE (First_Id, Second_Id) IN (SELECT 1, 1 FROM SYSIBM.SYSDUMMY1 UNION ALL                                 SELECT 1, 2 FROM SYSIBM.SYSDUMMY1 UNION ALL                                 SELECT 1, 3 FROM SYSIBM.SYSDUMMY1) 

Answer 2

Here's a very similar solution in postgresql:

SELECT tmp_table.val1, tmp_table.val2 FROM tmp_table WHERE (tmp_table.val1, tmp_table.val2) not in (select tmp_table2.val1, tmp_table2.val2 from tmp_table2);
