    <p>I have this table in mysql:</p> <pre><code>id | orden | pacient | per| exam | value | condition | date ---+---------------+----------+----+-------+-------+------------+-------------------- 1 | 201208082001 | 20652598 | 0 | 1017 | 9.00 | 0 | 2012-08-08 09:28:21 2 | 201208082001 | 20652598 | 0 | 1018 | 4.80 | 0 | 2012-08-08 09:28:21 3 | 201208082001 | 20652598 | 0 | 4104 | 213.00| 0 | 2012-08-08 09:28:21 4 | 201208082002 | 2799592 | 0 | 1017 | 7.70 | 0 | 2012-08-08 09:29:21 5 | 201208082002 | 2799592 | 0 | 1018 | 2.40 | 0 | 2012-08-08 09:29:21 6 | 201208082002 | 2799592 | 0 | 4104 | 43.00 | 0 | 2012-08-08 09:29:21 7 | 201208082003 | 6058327 | 0 | 1017 | 9.10 | 0 | 2012-08-08 09:30:02 8 | 201208082003 | 6058327 | 0 | 1018 | 4.00 | 0 | 2012-08-08 09:30:02 9 | 201208082003 | 6058327 | 0 | 4104 | 840.00| 0 | 2012-08-08 09:30:02 </code></pre> <p>What I need is this: each <em>set</em> of three rows has the same <code>orden</code> the same <code>pacient</code> and different <code>exams</code> and <code>values</code>. There is always a <code>CA</code> value, a <code>P</code> value and a <code>PTH</code> value. I need to check wherever a <code>pacient</code> have a <code>CA &gt; 5.5</code> and a <code>P &gt; 11</code> (and other bunch of things) in the original form of the table is very hard to get this quick and easy.</p> <pre><code>id | orden | pacient | per| CA | P | PTH | condition | date ---+---------------+----------+----+-------+------+------- +-----------+-------------------- 1 | 201208082001 | 20652598 | 0 | 9.00 | 4.80 | 213.00 | 0 | 2012-08-08 09:28:21 2 | 201208082002 | 2799592 | 0 | 7.70 | 2.40 | 43.00 | 0 | 2012-08-08 09:28:21 3 | 201208082003 | 6058327 | 0 | 9.10 | 4.00 | 840.00 | 0 | 2012-08-08 09:28:21 </code></pre> <p>This transposed table will be in a view, I have tried with sub-queries but is extremely slow, so. I hope you could help me.</p>

    1. COit'd be helpful if you explain exactly how the second table relates to the first. are you summing up the `value` column to producd `pth`? grouping? what's the grouping condition(s)?

    2. COPerhaps you can show the structure of the tables with an EXPLAIN statement for each.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
