Topic #: 8
Which two statements are true about the rules of precedence for operators?

Suggested Answer: A,B Vote an answer

A). True, arithmetic operators of equal precedence are evaluated from left to right within an expression, according to the standard SQL operator precedence. B. True, multiple parentheses can be used in an expression to change the order of operations and override the default precedence of operators.
C, D, and E are not correct because: C. The + binary operator does not have the highest precedence; multiplication and division have higher precedence in SQL. D. NULLS do not influence the precedence of operators in an expression; they may affect the result of an operation but not the order in which operators are evaluated. E. The concatenation operator (||) has lower precedence than arithmetic operators in SQL expressions.
