By default, count() ignores limit() and counts the results in the entire query. So when you for example do this, var a = db.collection.find(…).limit(10); running a.count() will give you the total count of your query.
I recommend working by obtaining the first page using: LIMIT 0, 10 then for the second page LIMIT 10, 10 then LIMIT 20, 10 for the third page, and so on.
To set the height and width to be 100% of the window (viewport) size, use: height: 100vh;//100% view height width: 100vw;// 100% view width . div { background-color: blue; height: 100vh; width: 100vw; position: absolute; top: 0; left: 0; color: white; } <div>some content here</div>
Why does “foo” appear in both queries? Because all rows that are returned have the same value for the status column. In that case the database is free to return the rows in any order it wants. If you want a reproducable ordering you need to add a second column to your order by statement … Read more
Is there any point using MySQL “LIMIT 1” when querying on primary key/unique field? It is not good practice to use LIMIT 1 when querying with filter criteria that is against either a primary key or unique constraint. A primary key, or unique constraint, means there is only one row/record in the table with that … Read more
In Python 3.7 and newer, there is no limit. This is the result of work done in issue #27213 and issue #12844; #27213 reworked the CALL_FUNCTION* family of opcodes for performance and simplicity (part of 3.6), freeing up the opcode argument to only encode a single argument count, and #12844 removed the compile-time check that … Read more
Just checked that this will work: (SELECT * FROM catalog_productimage ORDER BY date_modified LIMIT 10) UNION SELECT * FROM catalog_productimage WHERE id=5;
Order by id DESC Limit 1: db.query(“table”, null, “column=?”, new String[]{“value”}, null, null, “id DESC”, “1”);
There are many ways, one is to use a counter: $i = 0; foreach ($arr as $k => $v) { /* Do stuff */ if (++$i == 2) break; } Other way would be to slice the first 2 elements, this isn’t as efficient though: foreach (array_slice($arr, 0, 2) as $k => $v) { /* … Read more
You should always use INT_MAX, as that is the macro constant that is defined by the ISO C standard. The macro constant __INT_MAX__ is not specified by ISO C, so it should not be used, if you want your code to be portable. That macro is simply an implementation detail of the compiler that you … Read more
