    <p>i have two datasets and i need to compare these two datasets such that if ID does not exist in one table then i need to write insert Query else update query.</p> <p>For Ex:</p> <pre><code>Id in One dataset ID in second Dataset 1 1 2 2 3 4 </code></pre> <p>I need to insert ID 3 to second dataset.</p> <p>Here is my code for your reference:</p> <pre><code>if (ds.Tables[0].Rows.Count &gt; 0 || clientDS.Tables[0].Rows.Count &gt; 0) { for (int i = 0; i &lt; ds.Tables[0].Rows.Count; i++) { for (int j = 0; j &lt; clientDS.Tables[0].Rows.Count; j++) { if (ds.Tables[0].Rows[i]["Id"].ToString() == clientDS.Tables[0].Rows[j]["Id"].ToString()) { client.GetSingleValue("update customers set Name='" + ds.Tables[0].Rows[i]["Name"].ToString() + "',ContactPerson= '" + ds.Tables[0].Rows[i]["ContactPerson"].ToString() + "',Address='" + ds.Tables[0].Rows[i]["Address"].ToString() + "',TinNo='" + ds.Tables[0].Rows[i]["TinNo"].ToString() + "',ContactNo='" + ds.Tables[0].Rows[i]["Contactno"].ToString() + "',Report= '" + ds.Tables[0].Rows[i]["Report"].ToString() + "',Sync=0,Ids='" + ds.Tables[0].Rows[i]["Id"].ToString() + "' where id='" + ds.Tables[0].Rows[i]["Id"].ToString() + "' "); } else { client.GetSingleValue("insert into customers(id,Name,ContactPerson,Address,TinNo,ContactNo,Report,Sync,Ids) values('" + ds.Tables[0].Rows[i]["Id"].ToString() + "', '" + ds.Tables[0].Rows[i]["Name"].ToString() + "','" + ds.Tables[0].Rows[i]["ContactPerson"].ToString() + "', '" + ds.Tables[0].Rows[i]["Address"].ToString() + "', '" + ds.Tables[0].Rows[i]["TinNo"].ToString() + "', '" + ds.Tables[0].Rows[i]["Contactno"].ToString() + "', '" + ds.Tables[0].Rows[i]["Report"].ToString() + "',0,'" + ds.Tables[0].Rows[i]["Id"].ToString() + "')"); } } } } </code></pre> <p>Above code does not work. Pls rectify my issue.</p> <p>Thanks</p>

    1. COCan you outline how your approach is intended to work, basically write down the steps you want the code to take? I can see what is wrong here, but the only way to fix it is to write the actual code for you, it would be better if you could write the steps, and then we can either point out bugs in those steps, or bugs in the implementation.

    3. COi think you can do this in all SQL, no need to use the app. layer.

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).
