<h2 id="description">Description</h2>
|
||||
<p>In general when we are working with tables we want to make sure, the filtered dataset includes records and does not result in a runtime error, so we use <code>if</code> to handle the result of <code>Find()</code>, <code>FindSet()</code>, <code>Get()</code>, etc.
|
||||
This automatically causes on indent in source code and often the source code does not just contain one but two or more tables involved which leads to multi-level indentation.</p>
|
||||
<p>Basically this is a result of bad coding structure but maybe sometimes necessary. On the other hand this causes multiple <code>end;</code> usages and leads to the usage of colorization and other helpers to see which <code>begin</code> belongs to which <code>end;</code>.</p>
|
||||
<p>Instead of using <code>if (Record.FindSet()) then</code> to fetch records from a database it&rsquo;s good practice to use <code>if (not Record.FindSet()) then</code> following by an <code>exit();</code> to not further process the source code and make it clear for other developers where they can stop reading in certain cases.</p>
|
||||
<p>Furthermore, this more or less automatically leads to smaller and better structured procedures and reduces the complexity of the source code.</p>
