Hello to all,

I'm trying to fix a problem that is creating several scratches, I have a table in which I have a 4-character field some of these are special characters or from 127 on as the following string "I-" I have to be able to intercept and count them. With access the thing works but with mysql me by error: mysql illegal mix of collation (latin 1 swedish_ci, IMPLICIT) and (utf8_general_ci, COERCIBLE) for operazion ...

I tried trying to change collation but without success, I used both for the schema and for the tables the same collation:
ALTER TABLE `My tables`.`T_TOTALI_D` CHARACTER SET = utf8;

My query is more or less this, I missed the count because the condition is not resolved, TEST2 was only set to show consistency:

SELECT
`T_TOTALI_D``TOTALI_DATA` AS` TOTALI_DATA`,
IF ((TRIM (`T_TOTALI_D``TOTALI_MANS`) = ''),
'-',
IF ((LOCATE ('ÄÕ¹', LEFT (`T_TOTALI_D`.`TOTALI_MANS`, 1) <> 0)
'S',
'N')) AS `TEST2`
FROM
`T_TOTALI_D`
WHERE
(LEFT (`T_TOTALI_D`.`TOTALI_MANS`, 1) = 'Ä')

I would like to understand where I'm wrong, in advance thank you.
