``SELECT * FROM table_name WHERE LOWER(column_name) = 'value'
。这里将字段值和要匹配的值都转换为小写后再进行比较。, **示例(以SQL Server为例)**:SELECT * FROM table_name WHERE column_name COLLATE Latin1_General_CI_AS = 'Value'
。通过指定不区分大小写的排序规则来实现不区分大小写的比较。,,2. **使用ILIKE运算符(适用于部分数据库如PostgreSQL)**:, SELECT * FROM table_name WHERE column_name ILIKE '%value%'
。ILIKE运算符类似于LIKE运算符,但在匹配时不区分大小写。,,不同的数据库系统可能有不同的具体语法和方法来实现不区分大小写的查询,可以根据所使用的数据库类型选择合适的方式。Powered By Z-BlogPHP 1.7.3
