Filtering Data using Comparison Operator

22.5k

Comparison operators and filters are two different types of operations that can be used in SQL. While comparison operators compare two values and return TRUE if they are equal, filters compare one value against a list of values and returns TRUE if the value is found in the list.

The SQL comparison operator is used to compare two values and return a Boolean value based on the outcome of the comparison. The following example will show you how to use it:

  • SELECT * FROM users WHERE name = 'John' or age< 30;

SQL comparison operators are used to compare two or more values. They can be used to find out if one value is greater than, less than, equal to, or not equal to another value.

There are many types of comparison operators. Some of them include:

  • Greater than or less than
  • More than or less than
  • Greater than or equal to
  • Less than or equal to
  • More than or greater than

Comparison operators are used in SQL to compare two values and return a value based on the comparison.

The following are some of the common comparison operators:

  • =,<, >,<=, >=,
  • >=<, BETWEEN and IN.
