With one of my oracle databases, the ddl of each table is wrong in SQLTools (1.5r22, but the problem already existed in 1.4)
The symptoms : each VARCHAR2 value is multiplicated by 4.
Maybe the encoding parameters are not that ok, but
1) that problem does not occur with the last version of oracle sql developper
2) for some reasons, we can not change them
Thanks in advance for you help. SQL Tools is a great tool.
