Programming in C: Few Tidbits #6

[1] Case-insensitive String Comparison

strcasecmp() is the case-insensitive version of strcmp(). When building, make sure to include strings.h (note the plural form).

strncasecmp() is the counterpart to strncmp().

eg.,
..
#include <string.h>
void main(int argc, char** argv)
	..
        printf("n"%s" and "%s" are ", argv[1], argv[2]);
        strcasecmp(argv[1], argv[2]) ? printf(" .. not identical") : printf(" .. identical");
        ..

% ./strcompare next NeXT
"next" and "NeXT" are  .. identical

FROM ssh.sales
WHERE amount_sold > 1;

So, why didn’t Database In-Memory improve the performance of this query?

The answer is becomes a little clearer (more...)
