Which MySQL operator is the last in the order of operator precedence?

The correct answer is rooted in the understanding of operator precedence in MySQL. The operator that is last in the order of precedence is the logical OR operator. In SQL, operator precedence determines the sequence in which operators are evaluated within an expression.

While operators such as NOT and = have higher precedence, meaning they will be evaluated before OR in an expression, the precedence of the subtraction operator (-) also ranks higher than OR. This means that in any complex expression involving these operators, the evaluations will occur in a specific order, with OR being the last one to process.

Understanding this hierarchy is crucial when constructing SQL queries to ensure that expressions are evaluated in the intended manner, preventing unexpected results. This knowledge of operator precedence helps database practitioners write more accurate and efficient queries, enhancing overall query performance and reliability.
