Logical operators in dbms

There are two types of arithmetic operators as shown below: 1. Unary Arithmetic Operators: These operators act upon only one operand. The format followed by the Unary operator is 'OPERATOR OPERAND'. 2. Binary Arithmetic Operators: These operators act upon two operands. The format followed by the Binary operator is 'OPERAND OPERATOR OPERAND'. These are used to manage the changes made to the data in a table by DML statements. It also allows statements to be grouped together into logical transactions. COMMIT command. COMMIT command is used to permanently save any transaction into the database..
