Operator precedence

Concepts: sqlOperatorPrecedence

SQL evaluates operators in a specific order. Knowing this order prevents logical errors in complex conditions. Default Evaluation Order Parentheses () control the order in which SQL evaluates conditions. They act as explicit grouping tools that override default logical precedence. Without parentheses, SQL follows a fixed hierarchy: When a condition involves multiple operators, parentheses ensure the database interprets your intent correctly. They determine which comparisons are grouped and how combined conditions interact. Without Parentheses Parentheses for Control Parentheses let you override the default precedence and group conditions exactly how you intend. Explicit Grouping Nested Parentheses Parentheses can also be nested to group multiple logical layers: Here, parentheses group cond
