The call_req table has a column named zlocation with the inputs such as "0xAFC5C0D21B2C6E42BB31CBCFAE02FDD6" . Now , we need to add this column to the universe .But while adding this object with the field as casd.cr.zlocation , the following error is coming:"The expression type is not compatible with the object type" for all the datatypes(character,date,long text,number).
How can this be resolved ?
