Connector Ashx, select top X

Hello, I use your “Connector” dhtmlxConnector and I wanted to know if it is possible to use “Select Top X” in my query. For when I view my data “30 000” is too long, so I try to use “Select Top X” to accelerate. When I use the “Select Top X” all records are displayed without dealing with the “Top”. :question:

Thank you for helping me. :smiley:
