Scenario: In a database, you need to sort a result by a number of fields, sorted by a different weight, but the maximum weight of one field is limited to 30.Analysis: There are no a>30?30:a operations in SQL, only basic operations (+-*/), logical operations ( | | XOR) and so on.Answer:((a-a%30) 1) *30:a less than 30 o'clock, a-a%30 is 0, (01) *30 result is 0,a greater than or equal to 30 o'clock, the final result is 30(a-a%30) XOR 1: When a is greater than or equal to 30 o'clock, the

Consider the following: When the update value is the same as the original value, does SQL Server actually update or ignore it? For example: UpdateTbnameSetName='ABC' --The original value of name is ABC.WhereID=1 Another example is: UpdateTbnameSetName='ABC' --The

. This is not the case, the author in the Chrome development tools and Firefox console, the results are consistent. Issue two, front-end development work, often starting with a restore UI design. And in the coding process we often find that the design: a box background solid color (assuming: #f00), but with 75% opacity. Obviously, we can't simply set this up because we dom.style.backgroundColor = "#f00" don't have a translucent effect. Changed, we know that there is an RGBA in CSS3, which means

Document the more useful coding specifications (the guidelines are based on the Java language encoding specification and JAVASCRIPT programming specifications, combined with the personal experience and preferences of the author Nicholos Zakas).Some specifications for formatting (including indentation, line length, operator spacing, bracket spacing, object Direct volume, comments, single-line comments, multiline annotations, and so on) are not recorded here.A.3

Many stationmaster like original, because the original content can increase the weight of the site, so every day updates are racked their brains to produce their own original content, even if sometimes not written out, but still want to go east or west together to meet the search engine crawl, but such content value in

After 4.1.0 from PHP, the original location may change as the value of the usort is compared, as the document says: If two members compare as equal, their order in the sorted array is undefined. That is, if the 2 values of the comparison are the same, their order in the sort results is random. If you need to keep the original position of the same
