Which of the following is the correct order of precedence in MySQL?

When MySQL evaluates an expression, it looks at the operators to determine the order in which it should group the terms of the expression. Some operators have higher precedence, and evaluated earlier than others.
Which of the following is the correct order of precedence high to low in SQL?
Here, operators with the highest precedence appear at the top of the table, those with the lowest appear at the bottom. Within an expression, higher precedence operators will be evaluated first. The precedence of operators goes as follows: =, <, >, <=, >=, <>, != , ~=, ^=, IS NULL, LIKE, BETWEEN, IN.
What is the precedence of operators from higher to lower?
Operators in an expression that have higher precedence are executed before operators with lower precedence. For example, multiplication has a higher precedence than addition. … Left-associative operators of the same precedence are evaluated in order from left to right.
What is correct order of precedence in C?
The order of precedence determines which operators act upon a value first.

What is rule of precedence of operators in SQL?
Precedence is the order in which Oracle Database evaluates different operators in the same expression. When evaluating an expression containing multiple operators, Oracle evaluates operators with higher precedence before evaluating those with lower precedence.
What is operator precedence in MySQL?
Operator precedence specifies the order in which operators are evaluated when two or more operators with different precedence are adjacent in an expression. For example, 1+2/3 gives the different result as compared to (1+2)/3. Just like all other programming languages C, C++, Java etc. MySQL also has a precedence rule.
