The SQL database servers I have worked with cannot use and index for a
SELECT of the form
SELECT * FROM ATABLE
WHERE AFIELD LIKE ?
because there is no way to know the location of the wild card until the
parameter value is known. InterBase and Firebird allow
SELECT * FROM ATABLE
WHERE AFIELD STARTING WITH ?
which is equivalent to LIKE 'ABC%' and will use an index on AFIELD. Is
there a similar syntax in PostgreSQL?
One workaround might be to rewrite the query using some string function
(substring, position, or write your own) and index over that function.
