Case insensitive comparison NSString
...he casing for comparing is usually not a wise thing to do (e.g, the turkey test: moserware.com/2008/02/does-your-code-pass-turkey-test.html). When you have language-supported case comparison (such as caseInsensitiveCompare), always use that.

...too.
SYS_GUID() in Oracle is quite computation intensive function.
In my test database, t_even is a table with 1,000,000 rows
This query:
SELECT COUNT(SYS_GUID())
FROM t_even
runs for 48 seconds, since the function needs to evaluate each SYS_GUID() returned to make sure it's not a NULL.
