Why is SQL not case sensitive?
Hlo mate, The SQL Keywords are case-insensitive (SELECT, FROM, WHERE, etc), but are often written in all caps. Usually case-sensitive table and column names are the default on Linux MySQL and case-insensitive used to be the default on Windows, but now the installer asked about this during setup.
What does not case sensitive mean?
Text or typed input that is sensitive to capitalization of letters. For example, “Computer” and “computer” are two different words because the “C” is uppercase in the first example and lowercase in the second example. Anything that is not case-sensitive means that any uppercase or lowercase character can be entered.
Is SQL order by case sensitive?
MySQL/MariaDB and SQL Server default to case insensitive, and that would certainly make sense when sorting most text. Oracle and SQLite default to case sensitive, but have a relatively simple solution for a case insensitive sort. The default collation for my database is en_US.
How do I make SQL case sensitive?
SQL Server is, by default case insensitive; however, it is possible to create a case sensitive SQL Server database and even to make specific table columns case sensitive. The way to determine a database or database object is by checking its “COLLATION” property and look for “CI” or “CS” in the result.
What’s the opposite of case sensitive?
In computers, case sensitivity defines whether uppercase and lowercase letters are treated as distinct (case-sensitive) or equivalent (case-insensitive).
What is the difference between case sensitive and case insensitive?
Case sensitive programs recognize and distinguish case in file names and queries, but sometimes they will not return the correct file or perform the intended function without the correct case. In contrast, case insensitivity, or case blindness, does not distinguish between upper and lowercase.
How does SQL handle case sensitivity?
SQL Server is, by default, case insensitive; however, it is possible to create a case-sensitive SQL Server database and even to make specific table columns case sensitive. The way to determine if a database or database object is to check its “COLLATION” property and look for “CI” or “CS” in the result.
Is order by case-sensitive?
Sorting on the basis of the ASCII values differentiates the uppercase letters from the lowercase letters, and results in a case-sensitive order.
Is Oracle Order by case-sensitive?
Operation inside an Oracle database is always sensitive to the case and the accents (diacritics) of the characters. Sometimes you may need to perform case-insensitive or accent-insensitive comparisons and sorts.
Is where case insensitive in SQL Server?

Are keywords case sensitive in SQL?
Case Sensitivity in SQL Statements Case sensitivity rules in SQL statements vary for different statement elements, and also depend on what you are referring to and the operating system of the machine on which the server is running. SQL keywords and function names. Keywords and function names are not case sensitive.
Are MySQL database and table names case sensitive?
As a result, the default case sensitivity of database and table names depends on how the operating system on that host treats filenames. Windows filenames are not case sensitive, so a MySQL server running on Windows does not treat database and table names as case sensitive.
Are alias names case sensitive in SQL?
Alias names. By default, table aliases are case sensitive. You can specify an alias in any lettercase (upper, lower, or mixed), but if you use it multiple times in a statement, you must use the same lettercase each time. If the lower_case_table_names system variable is nonzero, table aliases are not case sensitive.
