    <p>Technology is winforms, using c# and sqlite as my database. I'm running this query:</p> <pre><code> string sql6 = "select YYMM, TotalTrans from t2 where cast(TotalTrans as Real) &lt; 1000.00"; </code></pre> <p>I then take the results from the query and populate them into lists, which i then use to populate a listview. </p> <p><em><strong>Problem:</strong> The results from column TotalTrans appear to be obviously greater than 1000, as I'm getting a ton of numbers which are even in the 100000s.</em></p> <p><strong>What I tried to do to fix it:</strong> Tried to cast twice because I thought for some reason the TotalTrans column wasn't being converted to float. </p> <pre><code> string sql6 = "select YYMM, cast(TotalTrans as Real) from t2 where cast(TotalTrans as Real) &lt; 1000.00"; </code></pre> <p>However this only made it worse as I got another problem : "Index was out of bounds of Array" in the following code (located in the "reader3["TotalTrans"] part.</p> <pre><code> string sql6 = "select YYMM, cast(TotalTrans as Real) from t2 where cast(TotalTrans as Real) &lt; 1000.00"; SQLiteCommand command3 = new SQLiteCommand(sql6, sqlite_conn); SQLiteDataReader reader3 = command3.ExecuteReader(); while (reader3.Read()) { double TotalTrans; DateTime yyyymm; if (DateTime.TryParse(reader3["YYMM"].ToString(), out yyyymm) &amp;&amp; double.TryParse(reader3["TotalTrans"].ToString(), out TotalTrans)) { YYMM.Add(yyyymm); TotalTransIrregularities.Add(TotalTrans); } } </code></pre> <p><strong>Note:</strong></p> <p>This is a side problem, but the main issue is the original problem I posted. The query should return values &lt;1000 but it is obviously not. When I tried to fix it using my approach I got another problem which said the index was out of bounds of the array. Whats the best fix? Thanks</p>

    1. COThe side problem about the index out side of the bounds looks like a name problem. Change the query to `select YYMM, cast(TotalTrans as Real) as TotalTrans ...` and that should fix one problem.

    2. COThis makes no sense at all. It can be a problem with delimiters: do your data have thousands separators?

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.
