How to comparing 2 field in AOT Query

The rules for creating query range value expressions are:

• Enclose the whole expression in parentheses.
  
• Enclose all subexpressions in parentheses.
  
• Use the relational and logical operators available in X++.
  
• Only use field names from the range's data source.
  
• Use the dataSource.field notation for fields from other data sources in the query.
