Parentheses can be used to change the binding precedence.Note that unlike the ANSI SQL operators, these operators are still operating according to C#’s two-valued Boolean Logic, meaning that they do not support null values as a third logical value.Logical Operators build up the Boolean_...
The order of precedence for the logical operators isNOT(highest), followed byAND, followed byOR. Permissions On SQL Server and SQL Managed Instance, requires theCREATE ANY EVENT SESSION(introduced in SQL Server 2022) orALTER ANY EVENT SESSIONpermission. ...
Parentheses can be used to override this precedence in a search condition. The order of evaluation of logical operators can vary depending on choices made by the query optimizer. For more information about how the logical operators operate on logic values, see AND, OR, and NOT....
When more than one logical operator is used in a statement, NOT is evaluated first, then AND, and finally OR. Arithmetic, and bitwise, operators are handled before logical operators. For more information, see Operator Precedence.In the following example, the color condition pertains to product ...

SQL also supports set operators (UNION, UNION ALL, INTERSECT, and MINUS), which combine sets of rows returned by queries, rather than individual data items. All set operators have equal precedence. See Also: Hierarchical Query Operators and Hierarchical Queries for information on the PRIOR operat...

Forces the Query Optimizer to try a plan that works for the maximum potential row size, possibly at the expense of performance. When the query is processed, intermediate tables and operators might have to store and process rows that are wider than any one of the input rows when the query ...

Because ORDER BY clauses are ignored in UNION ALL set-operator blocks, using these clauses in such queries would be non-deterministic. Do not use FETCH and OFFSET with these queries. Operators There are two types of operators: SQL logical operators, and mathematical operators. SQL Logical Opera...
