SQL unique varchar case sensitivity question

Question

I\'m trying to populate a SQL table with a list of words. The table itself it pretty simple:

CREATE TABLE WORDS(
  ID BIGINT AUTO_INCREMENT, 
  WORD VARCHAR(         


        

Answer 1

By default MySQL ignores differences in case and trailing spaces on varchar.

If you need it to be case sensitive, you can alter the table to be varchar(...) binary.

Use show create table to better understand how MySQL converts this to full notation.

If you need to pay attention to trailing spaces as well as be case sensitive, use varbinary instead of varchar.
