How Can I Perform Case-Insensitive Sorting in SQLite using ORDER BY?

Case-Insensitive Sorting in SQL with Order By Statement

When sorting data in SQLite, it's important to consider case sensitivity. By default, SQLite treats uppercase and lowercase characters as distinct, leading to results like:

A
B
C
T
a
b
c
g

To achieve case-insensitive sorting, SQL offers a special feature called "COLLATE." By using this feature, you can instruct SQLite to ignore case differences during the sorting process.

To sort results case-insensitively using the Order By statement, append the following syntax after the column name:

COLLATE NOCASE

For ascending order:

ORDER BY title COLLATE NOCASE ASC

For descending order:

ORDER BY title COLLATE NOCASE DESC

By incorporating the COLLATE NOCASE clause into your Order By statement, you can ensure that your results are sorted alphabetically, regardless of character case. This will yield the desired output:

A
a
b
B
C
c
g
T
