    <p>It <em>sounds</em> like your <code>time</code> string may have a carriage return <code>\r</code> in it. If that's the case, then outputting using your first method will <em>still</em> output the count and separator, but the <code>\r</code> will return to the start of the line and begin overwriting it.</p> <p>Your second method will not overwrite the count since it's on the previous line (a <code>\r</code> will have little visible effect if you're already at the start of the line).</p> <p>If you're running on a UNIX-like platform, you can pipe the output through something like <code>od -xcb</code> (a hex dump filter) to see if there is a <code>\r</code> in the output.</p> <p>Alternatively, if you have a string in your code, you can see if it contains a carriage return with something like:</p> <pre><code>std::string s = "whatever"; size_t pos = s.find ('\r'); if (pos != std::string::npos) { // carriage return was found. } </code></pre> <p>By way of example, the following program:</p> <pre><code>#include &lt;iostream&gt; int main (void) { std::string s1 = "strA"; std::string s2 = "\rstrB"; std::string s3 = "strC"; std::cout &lt;&lt; s1 &lt;&lt; '|' &lt;&lt; s2 &lt;&lt; '|' &lt;&lt; s3 &lt;&lt; '\n'; std::cout &lt;&lt; "=====\n"; std::cout &lt;&lt; s1 &lt;&lt; '|' &lt;&lt; '\n'; std::cout &lt;&lt; s2 &lt;&lt; '|' &lt;&lt; s3 &lt;&lt; '\n'; std::cout &lt;&lt; "=====\n"; size_t pos = s2.find ('\r'); if (pos != std::string::npos) std::cout &lt;&lt; "CR found at " &lt;&lt; pos &lt;&lt; '\n'; return 0; } </code></pre> <p>seems to output the following:</p> <pre><code>strB|strC ===== strA| strB|strC ===== CR found at 0 </code></pre> <p>but in fact that first line is actually:</p> <pre><code>strA|(\r)strB|strC </code></pre> <p>where <code>(\r)</code> is the carriage return.</p> <hr> <p>And keep in mind you rarely need <code>endl</code> - it's effectively a <code>\n</code> with a flush which is not really necessary in most cases. You can just get away with using <code>\n</code> and let the automated flushing take care of itself.</p>

    1. COI've changed to code to `if (newTime.time[0] == '\r') newTime.time[0] = ' '; cout<<count<<"|"<<newTime.time.c_str()<<"|"<<newCat<<"|"<<newCon<<endl;` but seems to still not working.

    2. CO@ljhljh235, it's not _necessarily_ at the start. It's hard to tell since `06:02:11:20:08` is a rather unusual time format, not one I've seen before. You're better off checking the entire string.

    3. COalready checked the whole string but the problem is still there. My time string is strictly created in the format mm:dd:hh:mm:ss and is strictly at the beginning of a line in a file stream. I read it by `getline(fin, oneline); Timestamp newTime(oneline.substr(0, 14));`

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.

SQuiL has stopped working due to an internal error.
