Hi, I was able to obtain the expected results successfully without any error by using cast function to convert the text data type to integer data type. For more details, you can refer to [CAST]( section of the Virtual DataPort VQL Guide. Also, for more information about error, I would check the vdp.log file located in <DENODO_HOME>/logs/vdp folder. If you still need help and if you are a valid Support User, you may open a Support Case at the Denodo Support Site and the Support Team will help you. Hope this helps!

Sometimes the cast operation works and some times it fails. Could it be related to something other than this.?

Hi, In order to use cast function, I would make sure I am using correct syntax to meet my requirement. Also, I would refer to [Type conversions permitted with the CAST function]( section of the Virtual DataPort VQL Guide. For Example: `cast('double', round((field1/field2), 10))` Hope this helps!
