You can use replace with either \t or CHAR(9):

UPDATE mytable SET email = REPLACE(TRIM(email), '\t', '');

You can still use the TRIM function, and specify the character to be trimmed:

UPDATE mytable SET email = TRIM(CHAR(9) FROM TRIM(email));

UPDATE yourtable SET your_field = TRIM(CHAR(9) FROM TRIM(your_field));

UPDATE mytable SET email = REPLACE(TRIM(email), CHAR(9), '')
