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

I made my UNIQUE key varchar(1000). It worked.

After some trial and error, I found anything greater than or equal to 1100 varchar would fail.

To clarify I did not try between 1001 to 1099.

Hope this helps.
