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.

Get a substring of a char* [duplicate]
...now the position and the length of the substring:
char *buff = "this is a test string";
printf("%.*s", 4, buff + 10);
You could achieve the same thing by copying the substring to another memory destination, but it's not reasonable since you already have it in memory.

is_file() is the fastest, but recent benchmark shows that file_exists() is slightly faster for me. So I guess it depends on the server.

Count(*) vs Count(1) - SQL Server
...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.

@FurkanAyhan That's odd. I went ahead and tested the code just to make sure and it does work. My guess is there's something else going on in your code that's making it error like that. Is it possible you forgot to close out a string somewhere or something like that?
