By default, MySQL search is case-insensitive (however, some character sets are always case-sensitive, such as czech ). This means that if you use col_name LIKE 'a % 'for search, you will get all columns starting with a or. If you want to make the search area case sensitive, make sure that one of the operands is case sensitive or binary. For example, if you are comparing columns and strings of the latin1 character set, you can use the COLLATE operator to enable one operand to be proofread by latin1_general_cs or latin1_bin. For example:
If you want to always process columns in case sensitive mode, you can declare them using case sensitive or binary checking.
Simple comparison operations (>=, >,=, <,<=, sort and group) are based on the "Sort value" of each character ". Characters with the same sorting value (for example, 'E', 'E', and 'distinct ')©') Will be treated as the same write character.
