I though MySQL is not case sensitive?
@drToddWolfe
@drToddWolfe Месяц назад
MySQL is case-sensitive depending on the operating system and the settings for table names, column names, and data. 1. **Database and Table Names**: On Linux, MySQL is case-sensitive with table names because Linux has a case-sensitive file system. On Windows, it is generally case-insensitive because the file system is not case-sensitive. You can control this behavior with the `lower_case_table_names` system variable. 2. **Column and Alias Names**: MySQL column names are case-insensitive by default in most environments. However, if you use backticks around column names, MySQL treats them as case-sensitive. 3. **Data**: The case sensitivity of data in a table depends on the collation used. For example, a `utf8_general_ci` collation is case-insensitive (`ci` stands for case-insensitive), while `utf8_bin` is case-sensitive. If you're looking for case-insensitivity or case-sensitivity in queries, you can adjust the collation or use functions like `LOWER()` or `UPPER()` to normalize case in comparisons.
