What is SQL operator?
SQL Operators are defined as a symbol or special reserved keywords used to specify some action that is performed on the given expression which includes several clauses to tell the system how the operators behave. Operators do calculations between the data items or operand and execute the Query result. It provides a condition in SQL statements or also combines multiple conditions and executes them between the operands (filters the results). The operators which are used between the data can come with single or with binary operands. All the operators are specified with the conditional statements along with the WHERE clause of SQL.

Operators are necessary to define a condition in SQL, as they act as a connector between two or more conditions. The operator manipulates the data and gives the result based on the operator’s functionality.
What is a logic operator?
Logical operators are those operators that take two expressions as operands and return TRUE or False as output. While working with complex SQL statements and queries, comparison operators come in handy and these operators work in the same way as logic gates do.
What is comparison in SQL?
Comparison operators in SQL are used to check the equality of two expressions. It checks whether one expression is identical to another. Comparison operators are generally used in the WHERE clause of a SQL query. The result of a comparison operation may be TRUE, FALSE or UNKNOWN. When one or both the expression is NULL, then the operator returns UNKNOWN. These operators could be used on all types of expressions except expressions that contain a text, ntext or an image. The table below shows different types of comparison operators in SQL:

Can you use brackets to force an order of operations with set operators?
Unlike the mathematical operators (such as addition and multiplication), there is no order of operations with set operators. They are treated equally and run in order in the query from start to finish. However, you can use brackets to force an order of operations with set operators.
