regexp_like()例子4 - match_type参数 您可以提供额外的参数来确定匹配类型。这允许您指定匹配是否区分大小写,是否包含行终止符,等等。 下面是一个指定区分大小写匹配和区分大小写匹配的例子: SELECT REGEXP_LIKE('Cat','^ca','c')'Case-Sensitive', REGEXP_LIKE('Cat','^ca','i')'Case-Insensitive'; ...
SELECT REGEXP_INSTR('Cat City is SO Cute!', 'c.t', 1, 1, 0, 'c') 'Case-Sensitive', REGEXP_INSTR('Cat City is SO Cute!', 'c.t', 1, 1, 0, 'i') 'Case-Insensitive'; 结果: +---+---+ | Case-Sensitive | Case-Insensitive | +---+---+ | 0 | 1 | +---+---...

Another factor to consider is case sensitivity. TheLIKEoperator is case-insensitive by default, but it can be made case-sensitive by using theBINARYkeyword. On the other hand, theREGEXPoperator is case-sensitive by default, but it can be made case-insensitive by using theREGEXP BINARYorREGEX...
(counting from the left) is returned. If count is negative, everything to the right of the final delimiter (counting from the right) is returned. SUBSTRING_INDEX() performs a case-sensitive match when searching for delim. count > 0, 返回str按delim分割后左侧第count开始左侧字符串 count < 0...
-- The REGEXP BINARY operator is used for case-sensitive pattern matching -- The '^' symbol signifies the beginning of a string -- Therefore, this query will return rows where the 'aut_name' column starts with a lowercase 'w' WHERE aut_name REGEXP BINARY '^w'; ...
INTERVAL expr unit expr represents a quantity. unit represents the unit for interpreting the quantity; it is a specifier such as HOUR, DAY, or WEEK. The INTERVAL keyword and the unit specifier are not case-sensitive. The following table shows the expected form of the expr argument for each...

我想把它设为case-non-sensitive.根据“MySQL 8.0参考手册”,“该变量描述数据目录所在的文件系统上文件名的大小写敏感性。OFF意味着文件名区分大小写,这意味着它们不区分大小写。这个变量是读的,因为它反映了文件系统属性,设置它对文件系统没有影响。”卡罗莱纳州 浏览1提问于2020-03-28得票数 1...
_ci (case insensitive忽略大小写) _cs (case sensitive区分大小写) or _bin (binary二进制)。忽略大小写,既排序和比较时忽略大小写差异。 例如:utf8mb4_unicode_ci(忽略大小写), utf8mb4_unicode_cs(大小写敏感),utf8mb4_bin(二进制) CHAR与VARCHAR ...
