    <p>Why would a mere 1.1 million rows cause problems? Most (if not all) RDBMS'es can handle many, many more (like billions) as long as storage etc. suffices ofcourse and as long as the partition can handle files of considerable size (e.g. Fat32 only supports up to 2GB per file for example).</p> <p>Also; you need to be more specific on what you're referring to when saying "before I begin seeing problems(if any)". What kind of problems? You might already have problems if you're not using correct indices for example which might slow queries down. That <em>might</em> be a problem but can, in some cases, also be fine.</p> <p>Another issue that <em>might</em> actualy be a problem is stuff like an autoincrement primary key field of type (unsigned) <code>int</code> which might overflow at values around 2.1 (signed) or 4.2 billion rows (unsigned) but since you're at 1.1 million rows currently that is way outside of what to worry about <em>now</em>. (Exact values are, ofcourse, 2<sup>31</sup>-1 and 2<sup>32</sup>-1 respectively for signed and unsigned <code>int</code>). In that case you'll have to think about using types like <code>bigint</code> or others (maybe even (var)char etc.) for your PK.</p> <p>The only thing interesting here, for MySQL specifically, <em>could</em> be: are you using InnoDB or MyISAM? I don't know the exact details since I'm not usually working with MySQL but I seem to remember that MyISAM can cause trouble (probably in old(er) versions like &lt;5.0 or something). <s>Correct me if I'm wrong.</s> Edit: read up <a href="https://stackoverflow.com/a/2716470/215042">here</a>. MyISAM supports a max. of 2<sup>32</sup> rows apparently, unless compiled with specific options.</p>

    1. COWhy would it cause problems? I am not a dba and my experience is limited to smaller tables sizes, hence why I am asking for your experience. Seeing any problems..: This is really an open ended question to ask what if any problems I may occur. As for inno/isam point: its Inno.

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.
