}
When running, Column count doesn't match value count at row 1
The user and password in my database are of the varchar type.
There is also the quotation mark in this line of code. String SQL = "insert into signs values ('" + text_usr.getText () + "," + text_pwd.getText () + "')"; new users are confused for help
