count

问题 I want to count two things under different conditions in one query. SELECT COUNT(*) AS count FROM table_name WHERE name = ? and SELECT COUNT(*) as count FROM table_name WHERE address = ?

问题 I have this loop at the same it will count the output: while ($wp_query->have_posts()) : $wp_query->the_post(); $current++; $current2++; Then to call the proper html class I need this for my design: <div class="span4 <?php if($current == 0) { echo 'first'; } elseif($current == 1) { echo 'second'; } elseif($current == 2) { echo 'first'; } elseif($current == 3) { echo 'second'; } ?>" id="<? echo $current; ?>"> The $count starts from 0 and $count2 from 1.

问题 Need some help in figuring out an formula to count the number of times a value is listed in a column. I will try and explain the requirement below. The below image show sample of data set. The requirement is to list out issues and actions per customer. As you can see, even from values clustered in cell, we need to find out individual unique values and then map it against the adjacent column or columns. 回答1: It just need an extra sheet/table to execute.. try : A1 = a,b,c A2 = b,c A3 = c,b,a A4
