Do not use field functions什麼意思

The phrase "do not use field functions" is not a standard English phrase and may be interpreted differently depending on the context in which it is used. However, if we assume that this phrase is related to programming or database management, it might mean one of the following:

1. Avoid using built-in database functions: In a database context, "field functions" could refer to built-in functions that operate on specific fields or columns within a table. For example, in SQL, there are functions like SUM, AVG, COUNT, MAX, and MIN that operate on columns. If someone says "do not use field functions," they might be telling you to avoid using these built-in functions when querying the database.

2. Avoid using specific functions within a field: In programming, a "field" could refer to a variable within a class or structure. If the context is programming, "do not use field functions" might mean that you should not use specific methods or functions that operate on a particular field or variable within your code. This could be due to performance reasons, side effects, or to maintain the consistency of the data.

3. Do not use functions that operate on the field level: In a more general programming context, "field functions" could refer to functions that operate on specific data fields. If someone tells you not to use field functions, they might be advising you to avoid using functions that operate on individual data elements or fields within an object or structure.

Without more context, it's difficult to provide a precise definition. If you can provide additional details about the context in which you encountered this phrase, I would be able to offer a more accurate interpretation.
