Knut Anders Hatlen commented on DERBY-4921:
-------------------------------------------
> (...) The only other case sensitive database I know is Oracle, (...)
Another example is PostgreSQL. The following code fails:
s.executeUpdate("create table t(x serial)");
s.executeUpdate("insert into t values (default)", new String[]{"X"});
==> Exception in thread "main" org.postgresql.util.PSQLException: ERROR: column
"X" does not exist
Changing the column name argument in the latter statement to lowercase (new
String[]{"x"}) makes it work.
PostgreSQL stores unquoted identifiers in lowercase, whereas Derby stores them
in uppercase, so it's not the exact same examples that cause problems on the
two databases, but at least they behave similarly in the sense that they treat
the argument as case-sensitive.
