The SQL language syntax is not case sensitive, but various conditions specified as part of your query might be. In this video, learn about SQL language case sensitivity—where it matters and where it does not.
- [Instructor] Note that by default,…the syntax of the SQL language in the Oracle database…is not case-sensitive.…So for example, writing select star from employees,…and we'll get exactly to what does this command…actually do later in our course.…But note that writing the query all in lowercase…will function just as well if…we change some of the words to uppercase.…So for example, switching from to from, all in uppercase,…and switching select to select with a capital S,…will actually function the same.…
Similarly, the same holds true for Oracle table names.…So changing the P and the L in employees to uppercase,…we will still be able to execute our query.…There are some specific occasions where…case sensitivity is important,…such as when filtering based on string values,…but we'll explore that in greater details…throughout the course.…Also note that SQL developer has a cool feature…where you can highlight a section of your SQL query,…and by pressing the following icon, you can change things…from lowercase to uppercase and using…
