Using LIKE in an Oracle IN clause

Question

I know I can write a query that will return all rows that contain any number of values in a given column, like so:

Select * from tbl where my_col in (val1, v         


        

Answer 1

No, you cannot do this. The values in the IN clause must be exact matches. You could modify the select thusly:

SELECT *
  FROM tbl
 WHERE my_col LIKE %val1%
    OR my_col LIKE %val2%
    OR my_col LIKE %val3%
 ...

If the val1, val2, val3... are similar enough, you might be able to use regular expressions in the REGEXP_LIKE operator.
