    <p>So this has been kicking my butt a bit. A little explanation is that I have 2 tables - equipment and ehours. Essentially, the equipment remains static and is transferred to a project and then is tracked on a daily basis on it's usage. <code>equipment.eid</code> is the unique identifier for the equipment and is then used in each ehours entry.</p> <p>Following is the query I am using to create my ouput. The output I'm getting is sorted correctly, but can't figure out how to output properly. </p> <pre><code>SELECT e.cid, e.eid, h.pid, h.hdate, e.eqid, e.name, e.make, e.model, h.hours, e.uid FROM equipment e LEFT JOIN ehours h on h.eid = e.eid AND MONTH(h.hdate) = $data[month] AND YEAR(h.hdate) = $data[year] ORDER BY cid ASC, eid ASC, pid ASC, hdate ASC </code></pre> <p>The problem I'm having is that in a given month a piece of equipment may be on 2 separate projects. The query shows the following...</p> <pre><code>cid | eid | pid | hdate | eqid | name | make | model | hours | uid 4 | 55 | 1 | 2012-11-01 | E8 | Forklift | Clark CGP25 | | 5 | 1 4 | 55 | 1 | 2012-11-07 | E8 | Forklift | Clark CGP25 | | 5 | 1 4 | 55 | 1 | 2012-11-10 | E8 | Forklift | Clark CGP25 | | 2 | 1 4 | 55 | 1 | 2012-11-13 | E8 | Forklift | Clark CGP25 | | 3 | 1 4 | 55 | 4 | 2012-11-13 | E8 | Forklift | Clark CGP25 | | 2 | 1 </code></pre> <p>The output needs to have a 2nd dimension of the dates which will be output in the proper days for the month. The final display will show all dates of the month. For instance, the first <code>eid</code> will output on one line with the <code>pid</code> of 1 and have the <code>hours</code> in the proper day of the month. It will then have a line afterwards with the same piece of equipment but having a <code>pid</code> of 4.</p> <p>So, anyway I'm needing to somehow create the dates into a 2nd dimension of the array that I can walk through as I output each row. Or maybe a 3rd dimension to catch the hours that are associated with each date? I've looked at several php methods to attempt this, but have been unsuccessful so far. Any help is greatly appreciated. Wow - this turned into a novel.</p> <p><strong>Edited:</strong></p> <p>The following is what output should be...</p> <pre><code>pid | eqid | name | make | 11-01 | 11-02 | ... | 11-07 | ... | 11-10 | ... | 11-13 1 | E8 | Forklift | Clark CGP25 | 5 | 0 | ... | 5 | ... | 2 | ... | 3 4 | E8 | Forklift | Clark CGP25 | 0 | 0 | ... | 0 | ... | 0 | ... | 2 </code></pre> <p>Would also have to account for a NULL value for <code>pid</code></p>

    1. COso what you want to output is exactly what you recieve you just want to have a line between 2012-11-13 pid 1 and 2012-11-13 pid 4?

    2. COYes - for one. I'm thinking of a spreadsheet. First line would have the project, then equipment information, then all the days of the month and year that is selected, then in each day of the month would be the proper hours. The next line would have the same equipment but the next pid and again with the proper hours noted on the correct dates. If there was only one date for each piece of equipment it's simple.

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.
