Compares a string expression to a pattern in an SQL expression.
SyntaxRemarksexpressionLike “pattern”
The Like operator syntax has these parts:
Part
Description
expression
SQL expression used in a WHERE clause .
pattern
String or character string literal against which expression is compared.
You can use the Like operator to find values in a field that match the pattern you specify. For pattern, you can specify the complete value (for example,
Like “Smith”), or you can use wildcard characters to find a range of values (for example,Like “Sm*”).In an expression, you can use the Like operator to compare a field value to a string expression. For example, if you enter
Like “C*”in an SQL query, the query returns all field values beginning with the letter C. In a parameter query, you can prompt the user for a pattern to search for.The following example returns data that begins with the letter P followed by any letter between A and F and three digits:
Like “P[A-F]###”The following table shows how you can use Like to test expressions for different patterns.

SQL Comparison Operators - SQL Tutorial
This tutorial introduces you to the SQL comparison operators and shows you how to use them to form conditions for filtering data.

SQL comparison operators are essential tools for filtering data in SQL queries. They allow you to compare two expressions and determine if they meet specific criteria. Here are the primary SQL comparison operators and their usage:
Equal to Operator (=)
The equal to operator (=) checks if two expressions are equal. It returns true if the left expression is equal to the right expression. For example, to find employees with the last name 'Himuro':
SELECT employee_id, first_name, last_nameFROM employeesWHERE last_name = 'Himuro';Note that the equal operator cannot be used to compare null values. Instead, use the IS NULL operator:
SELECT employee_id, first_name, last_name, phone_numberFROM employeesWHERE phone_number IS NULL;Not Equal to Operator (<>)
The not equal to operator (<>) checks if two expressions are not equal. It returns true if the left expression is not equal to the right expression. For example, to find employees whose department id is not 8:
