Pattern Matching

How can I use SQL to specify a query like the example below:
    select * from mytable where column like 'a[bc]'
This should match both "ab" and "ac" but not "ad."

SQL does not have strong pattern matching facilities. For the example you've provided, you'll have to construct the query using the IN predicate:

    SELECT * FROM MyTable 
        WHERE col IN (ab, ac);
If your list is extensive, you might want to use a subquery:
    SELECT * FROM MyTable 
        WHERE col IN 
            (SELECT value FROM ValueTable);
