MySQL 8.0 - implementing VARCHAR Collation When Using LIKE with Wildcards
I need some guidance on I've been banging my head against this for hours. I'm getting frustrated with I'm working with an scenario with MySQL 8.0 where I'm trying to perform a case-insensitive search on a VARCHAR column using the `LIKE` operator with wildcards. The column is defined with `utf8mb4` charset and `utf8mb4_general_ci` collation, and I expect that searches should be case insensitive. However, when I run the following query: ```sql SELECT * FROM my_table WHERE my_column LIKE 'abc%'; ``` I'm getting results that include entries where `my_column` starts with `ABC`, which is expected. But if I try a search like this: ```sql SELECT * FROM my_table WHERE my_column LIKE 'a%'; ``` I get results that include entries starting with `B`, which is definitely not what I expect. I've double-checked my collation settings for both the table and the column, and they seem correct. I also tried using `LOWER()` on both sides of the comparison: ```sql SELECT * FROM my_table WHERE LOWER(my_column) LIKE LOWER('a%'); ``` But that doesn’t resolve the scenario either. It's important to note that when I switched the collation to `utf8mb4_bin`, the query worked as expected, but I need to maintain case insensitivity. Could the scenario be related to how MySQL optimizes the query or is there an underlying question with the collation? Any insights on how to fix this behavior without changing the collation would be appreciated! I'm coming from a different tech stack and learning Sql. What am I doing wrong?
