可以使用like查询将各自的字符串与表值进行比较。

Select column name from table_name where column name like '各自的比较值';

SELECT * FROM ... WHERE name = 'someone' COLLATE NOCASE

另一种选择可能对您的情况有意义，也可能没有意义，那就是实际上有一个单独的列，其中包含现有列的预先低分值。可以使用SQLite函数LOWER()填充该列，然后可以对该列执行匹配。

显然，它增加了冗余和潜在的不一致性，但如果您的数据是静态的，它可能是一个合适的选择。

你可以这样做:

SELECT * FROM ... WHERE name LIKE 'someone'

(这不是解决方案，但在某些情况下非常方便)

"The LIKE operator does a pattern matching comparison. The operand to the right contains the pattern, the left hand operand contains the string to match against the pattern. A percent symbol ("%") in the pattern matches any sequence of zero or more characters in the string. An underscore ("_") in the pattern matches any single character in the string. Any other character matches itself or its lower/upper case equivalent (i.e. case-insensitive matching). (A bug: SQLite only understands upper/lower case for ASCII characters. The LIKE operator is case sensitive for unicode characters that are beyond the ASCII range. For example, the expression 'a' LIKE 'A' is TRUE but 'æ' LIKE 'Æ' is FALSE.)."

这对我很有效。 从表_name中选择测试名

简单地说，你可以在SELECT查询中使用COLLATE NOCASE:

SELECT * FROM ... WHERE name = 'someone' COLLATE NOCASE
