Answer with Explanation

Strategies to optimize SQL queries in X++:

  • Use Indexes: Ensure that appropriate indexes are used to speed up query execution.
  • Select Specific Columns: Instead of selecting all columns, specify only the needed columns.
  • Use firstOnly or forUpdate: Fetch only the required records.

select firstOnly CustTable where CustTable.AccountNum == '4000';
