string always ends up in LONG VARCHAR

[steppel]

I define the datatypes to create a table. When using string(100) it will end up in LONG VARCHAR. I do have multiple VARCHAR columns and now it always ends in teradata [Error 3933] [SQLState HY000] The Maximum Possible Row Length in the Table is too Large.

datatypes = { 'example':sqlalchemy.types.String(100) -> LONG VARCHAR
...
}
final_table.to_sql('test',td._backend._conn,schema='test',index=False,dtype=datatypes,if_exists='replace')

@steppel You should use teradatasqlalchemy which will succeed sqlalchemy-teradata. There is also a tutorial in the wiki section that points to docs on sql data types:
