By default, MySQL searches are case-insensitive (although there are some character sets that are never case-insensitive, such asczech). That means that if you search withcol_name LIKE 'a%', you will get all column values that start withAora. If you want to make this search case-sensitiv...
so nonbinary string comparisons are case-insensitive by default. This means that if you search withcol_nameLIKE 'a%', you get all column values that start withAora. To make this search case-sensitive, make sure that one of the operands has a case-sensitive or binary collation. For exampl...
For example, to perform a case-insensitive search, use COLLATE with the INFORMATION_SCHEMA column name: mysql> SELECT SCHEMA_NAME FROM INFORMATION_SCHEMA.SCHEMATA WHERE SCHEMA_NAME COLLATE utf8mb3_general_ci = 'test'; +---+ | SCHEMA_NAME | +---+ | test | +---+ mysql> SELECT SCHEMA...
2)utf8_general_ci:utf8_genera_ci不区分大小写,ci为case insensitive的缩写,即大小写不敏感。 3)utf8_general_cs:utf8_general_cs区分大小写,cs为case sensitive的缩写,即大小写敏感。 注:我本机使用5.7 版本不支持 utf8_general_cs 字符集,创建报错。
If the result of a string operation on anINFORMATION_SCHEMAcolumn differs from expectations, a workaround is to use an explicitCOLLATEclause to force a suitable collation (Section 9.1.7.2, “Using COLLATE in SQL Statements”). For example, to perform a case-insensitive search, useCOLLATEwith th...

SQLLIKE. I am not aware of a straight forward way to do a case insensitive search. Converting the entire JSON document to upper or lower case and comparing with a correspondingly modified search value is no option as the conversion would also affect JSON object member names (your “keys”)...
I would like to perform a case insensitive search on a BLOB column. It needs to be a BLOB because some data is actually binary. My example statement is: select headline from ticker where message LIKE "%Peugeot%"; Problem is that this is case sensitive (message is the BLOB column). I ...
