    <p>Thanks for your help!</p> <p>I'd like to output all companyName entries that have uploads across any of their serverFiles as:</p> <p><strong>companies.companyName - count(files.fileID) - sum(serverFiles.uniqueUploads)</strong></p> <pre><code>Initech Ltd. - 11 - 24931 Epiphyte Inc. - 23 - 938821 </code></pre> <p>Here are the relavent parts of my table structure:</p> <p><strong>Table: companies</strong></p> <pre><code>companyID (INT) - companyName (TEXT) </code></pre> <p><strong>Table: campaigns</strong></p> <pre><code>campaignID(INT) - companyID (INT) </code></pre> <p><strong>Table: files</strong></p> <pre><code>fileID (INT) - campaignID (INT) </code></pre> <p><strong>Table: serverFiles</strong> serverFileID (INT) - fileID (INT) - uniqueUploads(INT)</p> <p>Each company can have multiple campaigns.</p> <p>Each campaign can have multiple files.</p> <p>Each file can have multiple serverFiles</p> <p>The query I tried to use is as follows:</p> <pre><code>SELECT companies.companyName, sum(serverFiles.uniqueUploads), count(files.fileID) FROM companies INNER JOIN campaigns on companies.companyID = campaigns.companyID INNER JOIN files on files.campaign = campaigns.campaignID LEFT OUTER JOIN serverFiles on serverfiles.fileID = files.fileID GROUP BY serverFiles.uniqueUploads, files.fileID ORDER BY sum(serverFiles.uniqueUploads) DESC; </code></pre> <p>However, this returns multiple entries for each company (as it creates multiple outputs for each company - one for each campaign under the company). </p> <p>eg:</p> <p><strong>companies.companyName - count(files.fileID) - sum(serverFiles.uniqueUploads)</strong></p> <pre><code>Initech Ltd. - 2 - 234234 (for initech campaign1) Initech Ltd. - 4 - 223323 (for initech campaign2) Epiphyte Inc. - 13 - 6434 (for epiphyte campaign1) Initech Ltd. - 1 - 554 (for initech campaign3) Epiphyte Inc. - 13 - 7544 (for epiphyte campaign2) Epiphyte Inc. - 11 - 74545 (for epiphyte campaign3) Epiphyte Inc. - 23 - 456544 (for epiphyte campaign4) </code></pre> <p>How do I change the query to only give me one response back for each company, summing up all of the campaigns under that company. </p> <p>Thanks so much for any assistance.</p>

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.
