Expression precedence

Precedence of operations from highest to lowest is:
  • (), ?, Constant (including sign), NULL, ColumnReference, ScalarSubquery, CAST
  • LENGTH, CURRENT_DATE, CURRENT_TIME, CURRENT_TIMESTAMP, and other built-ins
  • unary + and -
  • *, /, || (concatenation)
  • binary + and -
  • comparisons, quantified comparisons, EXISTS, IN, IS NULL, LIKE, BETWEEN, IS
  • NOT
  • AND
  • OR

You can explicitly specify precedence by placing expressions within parentheses. An expression within parentheses is evaluated before any operations outside the parentheses are applied to it.
