The SQL language provides the capabilities to filter based on partial string values. In this video, learn how to filter using partial strings values with the LIKE % keyword and more.
- [Instructor] We can also filter…based on exact string matches.…So for example instead of selecting…all rows for all employees from our employees tables…whose last names start with the letter E,…we can also chose to display all rows…where the last name value matches…an exact string literal.…So let's start by typing select first name…comma last name from employees,…to see an output of all employees in our employees table.…
Now assuming that I only want to see employees…whose last name is King, exactly King,…I can type, where last name equals…and type King.…Running this query will show us two rows,…Janette King and Steven King.…Know that when matching based on exact string values,…or literal string values, I do have to match…the case sensitivity of the data in my table.…
So because both of these employees…have the last name of King with a capital K…I need to make sure that I specify the exact same value…with the same case sensitivity in my query.…So capital K in our case.…If I change the value of the literal string…
