SQL Error [1064] [42000]: You have an error in your SQL syntax

Question

When I add a new row to the table I can delete using the command:

DELETE FROM ebdb.tb_categoria as tc WHERE id = 790;

However, the lines that already exist cannot delete and returns the error:

check the manual that Corresponds to your Mysql server version for the right syntax to use near 'as Tc WHERE id = 790' at line 3

I find it strange because, changes like UPDATE I can run on these lines. I am using Dbeaver 6.2.2

Thanks in advance.
