    <p>I'm trying to solve the following problem in java and msql.</p> <p>if I run the following query directly in mysql records sorted correctly. But when the same query is done through java or connector, NOT the records are sorted. It is as if the query is performed by comparing string and not integer.</p> <blockquote> <p>select * from table1 order by cast(col2 as signed) limit 0,10</p> </blockquote> <p>Code example:</p> <pre><code>public ArrayList&lt;Customers_voip_terminations_details&gt; select_Customers_voip_terminations_details_all(int voipID, int fromrow, int torow, String orderby) throws SQLException { String query = ""; if (fromrow == 0 &amp;&amp; torow == 0) { query = "select * from customers_voip_terminations_details where voipid=? order by cast(? as signed)"; this.preparedStatement = conn.prepareStatement(query); this.preparedStatement.setInt(1, voipID); this.preparedStatement.setString(2, orderby); } else { //Tools tool = new Tools(); query = "select * from customers_voip_terminations_details where voipid=? order by cast(? as signed) LIMIT ?, ?"; this.preparedStatement = conn.prepareStatement(query); this.preparedStatement.setInt(1, voipID); this.preparedStatement.setString(2, orderby); this.preparedStatement.setInt(3, fromrow); this.preparedStatement.setInt(4, torow); } this.resultSet = this.preparedStatement.executeQuery(); ArrayList&lt;Customers_voip_terminations_details&gt; result = new ArrayList&lt;Customers_voip_terminations_details&gt;(); while (this.resultSet.next()) { Customers_voip_terminations_details item = new Customers_voip_terminations_details(); item.registerid = this.resultSet.getInt("registerid"); item.date1 = this.resultSet.getInt("date1"); item.date2 = this.resultSet.getInt("date2"); item.voipid = this.resultSet.getInt("voipid"); item.customerid = this.resultSet.getInt("customerid"); item.countryid = this.resultSet.getInt("countryid"); item.uniquesearch = this.resultSet.getString("uniquesearch").trim(); item.networktypeid = this.resultSet.getInt("networktypeid"); item.zone = this.resultSet.getString("zone").trim(); item.whitecli = this.resultSet.getInt("whitecli"); item.whiteroute = this.resultSet.getInt("whiteroute"); item.acd = this.resultSet.getFloat("acd"); item.asr = this.resultSet.getFloat("asr"); item.pdd = this.resultSet.getInt("pdd"); item.billingtime = this.resultSet.getInt("billingtime"); item.rate = this.resultSet.getDouble("rate"); item.status = this.resultSet.getInt("status"); result.add(item); } this.resultSet.close(); this.preparedStatement.close(); return result; } </code></pre>

    2. COThat's puzzling. I suspect that the query text being submitted from Java does not match the query text being run in the native environment. If that's not the case, and this really is a problem, you might try something like `... ORDER BY col2 + 0 LIMIT ...` as a way to get `col2` evaluated in a numeric context (as an alternative to the CAST function.) I don't have an answer for you, because I've never encountered this type of problem before. (Again, my suspicion is that this is not the query text that Java is submitting to MySQL.)

    3. COI have tried several queries and all throw the same error. The column "uniquesearch" is varchar but with numerical data. Example: 44, 440, 598, 5980 etc.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
