Be aware that MERGE has sometimes has performance issues. &nbsp;There are also some claims of faulty logic.<br />

<div class="content wysiwyg-content">
I have a table that i am using to load data in my database, i want to move the data to another table, and merge the rows that have the same Call_ID into one row.<br />
<br />
so if call_id is the same, then it would only create one row in the new table, is this even possible with a query ?
