Use the SQL LIKE operator and SQL wildcard strings in a SQL WHERE clause when you want to compare a value against a character string field so that the query returns database information based on commonalities. This is known as pattern matching and is a very common search scenario.
For example, to return data for employees whose last name starts with AL and ends with anything, you would build a query that looks like this:
<CFQUERY NAME="GetEmployees" DATASOURCE="HRApp"> SELECT FirstName, LastName, StartDate, Salary, Contract FROM Employees WHERE LastName LIKE 'AL%' </CFQUERY>
|Note:||By default, SQL is not case-sensitive.|
