SQL - retain ordering based on the query params

Question

I\'m trying to perform a SELECT with an IN clause and I would like to be able to have the results returned in the same order as the elements in my list

Answer 1

Insert the values into a temporary table and join your select to that.

You can then do a natural order on your temporary table column.

CREATE GLOBAL TEMPORARY TABLE sort_table (
  value       VARCHAR2(100),
  sort_order  NUMBER
) ON COMMIT DELETE ROWS;

INSERT INTO sort_table VALUES ('B123',1);
INSERT INTO sort_table VALUES ('B483',2);
... etc. ...

select * from mytable
inner join sort_table
on mytable.mycolumn = sort_table.value
order by sort_table.sort_order;

To clear the temporary table, just COMMIT.
