Hi jitendrat76652144,

There is a second queryDef in this code which you have completely skipped

Without this, your while loop code will run into an infinite loop.

Hi Jitendra,

You can try this code in a JS activity

var recordsToFetchPerBatch = 20;  
var currentStartLine = 0;
var query = xtk.queryDef.create(
  <queryDef schema="cus:mySchema" operation="select" lineCount={recordsToFetchPerBatch} startLine={currentStartLine}>
    <select>
      <node expr="@id"/>    
    </select>
  </queryDef>);
var result = query.ExecuteQuery();
try
{
while (result != "") 
{  
for each (var record in result) 
{
currentStartLine++;
//do your stuff
} // end for
query = xtk.queryDef.create(
<queryDef schema="cus:mySchema" operation="select" lineCount={recordsToFetchPerBatch} startLine={currentStartLine}>
<select>
  <node expr="@id"/>    
</select>
  </queryDef>);
var result = query.ExecuteQuery();
} // end while
} 
catch (e) 
{
  logError("*** FAILED ***");
}
