Infographic Illustration on SQL operators. SQL Operators are used to manipulate data within SQL statements. These operators can be categorized into several groups, including arithmetic operators, comparison operators, logical operators, and wildcard operators. Arithmetic operators are used to perform mathematical operations on data, including addition (+), subtraction (-), multiplication (*), division (/), and modulo (%). Comparison operators are used to compare values within SQL statements. These operators include equals to (=), not equals to (!= or <>), less than (<), greater than (>), less than or equal to (<=), and greater than or equal to (>=). Logical operators are used to combine multiple conditions within SQL statements. These operators include AND, OR, and NOT. Wildcard operators are used to search for specific patterns within data. These operators include the percent symbol (%), which represents any number of characters, and the underscore symbol (_), which represents a single character. By using these operators, you can create powerful and complex SQL statements to manipulate data in various ways.
