In query expressions, what typically must be included alongside a field name?

In query expressions, including additional syntax alongside a field name is essential because it ensures that the query is correctly interpreted based on the data type or the operation being performed. Different field types may require specific syntax to function as intended. For example, when dealing with numbers, particularly when querying ranges or using aggregate functions, the syntax may require special characters or operators to define the conditions accurately. Similarly, string comparisons might need quotation marks, while dates could require specific formats.

By including this additional syntax, users can construct precise and effective queries that return accurate results. This ensures that the query engine understands the context and the specific requirements of the field being referenced, facilitating smooth data retrieval and analysis.
