You can not work that way! Mysql Database All Fields Recognized as Text

Using MySql (mariadb) database when there are JOINs in the main query
all sql fields are seen as TEXT fields.
example the query Grid Application:
SELECT bi.Codice,bi.DataMov,bi.CodDistributore FROM BatInc bi
LEFT JOIN Magaz m ON m.Codice=bi.CodDistributore
all fields are seen from scriptcase as text fields.
If we remove the JOIN fields are recognized correctly.
