() (Parentheses) (SSIS Expressions)
Identifies the evaluation order of expressions. Expressions enclosed in parentheses have the highest evaluation precedence. Nested expressions enclosed in parentheses are evaluated in inner-to-outer order.
Parentheses are also used to make complex expressions easier to understand.
This example shows how the use of parenthesis modifies the precedence of operators. The first expression evaluates to 100, whereas the second one evaluates to 31.
