SQL operators are special characters reserved to perform certain operations, making it easy to write complex SQL queries. Arithmetic operators are used for mathematical calculations on the data in tables. Logical operators evaluate a given expression and return true or false by using ALL, ISNULL, EXISTS, BETWEEN, LIKE, etc. Comparison operators check the relation between two values using <, >, <=, >=, etc. Bitwise operators are used on integer type values to perform bit manipulations by using ~, |, ^, etc. Compound operators perform operations on a value before setting its variable’s value to the result using +=, -=, *=, /=, etc. String operators are used to perform concatenation and pattern matching for the values in the table.
