    <p>I have code similar to the following:</p> <pre><code>$data['someField'] = (isset($_POST['someField'])) ? 'Y' : 'N'; $stmt = $db-&gt;prepare("INSERT INTO public.someTable (someField) VALUES (':someField');"); $stmt-&gt;bindParam(':someField', ($data['someField']), PDO::PARAM_STR, 1); $db-&gt;beginTransaction(); $stmt-&gt;execute(); $db-&gt;commit(); </code></pre> <p>The field is a character(1) that contains either a Y or N (I'd rather use a bool/int(1), but I can't change that unfortunately). As you can see, this takes the POST data from an HTML form and set Y or N based on a checkbox. The variable looks properly set when I echo it. The query works if I manually put a 'Y' or 'N' into the statement, but when using bindParam() I get the following error:</p> <pre><code>SQLSTATE[22001]: String data, right truncated: 7 ERROR: value too long for type character(1) </code></pre> <p>The really odd thing is even if I do something like this:</p> <pre><code>$stmt-&gt;bindParam(':someField', substr($data['someField'], -1), PDO::PARAM_STR, 1); </code></pre> <p>I still get the error. From the user comments on the function page at php.net:</p> <blockquote> <p>Steve M 19-Nov-2009 07:28 Note that when using PDOStatement::bindParam an integer is changed to a string value upon PDOStatement::execute(). (Tested with MySQL).</p> </blockquote> <p>There is no further mention of this, or anything on how to get around it. I am assuming that this the root of the problem. I have also tried using bindValue() with no change.</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.
