...faster than with a tree algorithm (O(1) instead of log(n)), but you cannot select ranges (everything in between x and y). Tree algorithms support this in Log(n) whereas hash indexes can result in a full table scan O(n). Also the constant overhead of hash indexes is usually bigger (which is no factor...

... Yes, the picture is better than the text in the selected answer, but this is the same solution, and it is posted more than a year later. Too bad that the two answers are not merged and the rep points shared :-) – mins Apr 28 '15 at 21...

... The bootstrap docs says about this: Requires custom widths Inputs, selects, and textareas are 100% wide by default in Bootstrap. To use the inline form, you'll have to set a width on the form controls used within. The default width of 100% as all form elements gets when they got the cl...

...es not understand how to resolve this problem. Second problem is using old select socket interface withour modern IOCP version of socket interoperation. Could you improve Widnows support? – Vitold S. Jan 3 '16 at 2:51 ...

... Alternatively you can use CONCAT_WS which skips NULL values. For example SELECT CONCAT_WS(', ','First name',NULL,'Last Name'); gives 'First name, Last Name' – BarneySchmale Aug 8 '16 at 11:00 ...
