For instance, a clause of - the form - - ... WHERE smallint_column = 42 - - will not use an index, because the system assigns type - integer to the constant 42, and - PostgreSQL currently - cannot use an index when two different data types are involved. A - workaround is to single-quote the constant, thus: - - ... WHERE smallint_column = '42' - - This will cause the system to delay type resolution and will - assign the right type to the constant. - - - --- 437,442 ----
