Joining on multiple columns in Linq to SQL is a little different. var query = from t1 in myTABLE1List // List<TABLE_1> join t2 in myTABLE1List on new { t1.ColumnA, t1.ColumnB } equals new { t2.ColumnA, t2.ColumnB } … You have to take advantage of anonymous types and compose a type for the multiple columns you … Read more
I’ve spoken to Tab Atkins (author of the flexbox spec) about this, and this is what we came up with: HTML: <div class=”content”> <div class=”box”> <div class=”column”>Column 1</div> <div class=”column”>Column 2</div> <div class=”column”>Column 3</div> </div> </div> CSS: .content { flex: 1; display: flex; overflow: auto; } .box { display: flex; min-height: min-content; /* needs vendor … Read more
Get all the values from MySQL: $post = array(); while($row = mysql_fetch_assoc($result)) { $posts[] = $row; } Then, to get each value: <?php foreach ($posts as $row) { foreach ($row as $element) { echo $element.”<br>”; } } ?> To echo the values. Or get each element from the $post variable
Use paste. df$x <- paste(df$n,df$s) df # n s b x # 1 2 aa TRUE 2 aa # 2 3 bb FALSE 3 bb # 3 5 cc TRUE 5 cc
With Entity Framework 6.1, you can now do this: [Index(“IX_FirstAndSecond”, 1, IsUnique = true)] public int FirstColumn { get; set; } [Index(“IX_FirstAndSecond”, 2, IsUnique = true)] public int SecondColumn { get; set; } The second parameter in the attribute is where you can specify the order of the columns in the index.

I usually do this using zip: >>> df = pd.DataFrame([[i] for i in range(10)], columns=[‘num’]) >>> df num 0 0 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8 9 9 >>> def powers(x): >>> return x, x**2, x**3, x**4, x**5, x**6 >>> df[‘p1’], df[‘p2’], df[‘p3’], df[‘p4’], df[‘p5’], … Read more
You cannot change the order of columns in smaller screens but you can do that in large screens. So change the order of your columns. <!–Main Content–> <div class=”col-lg-9 col-lg-push-3″> </div> <!–Sidebar–> <div class=”col-lg-3 col-lg-pull-9″> </div> By default this displays the main content first. So in mobile main content is displayed first. By using col-lg-push … Read more
Group By X means put all those with the same value for X in the one group. Group By X, Y means put all those with the same values for both X and Y in the one group. To illustrate using an example, let’s say we have the following table, to do with who is … Read more
The solution to this is actually very easy, but not at all obvious. You have to trigger something called a “block formatting context” (BFC), which interacts with floats in a specific way. Just take that second div, remove the float, and give it overflow:hidden instead. Any overflow value other than visible makes the block it’s … Read more
