日志显示：ALTER TABLE ADD test1 INT NOT NULL DEFAULT -1 ;
跟踪发现这里有问题：
} else {
session := engine.NewSession()
session.Statement.RefTable = table
session.Statement.tableName = tbName
defer session.Close()
err = session.addColumn(col.Name)
}
后续addColumn函数中，statement判断表名部分使用了tblname和alttbname，这里只设置了tableName，导致
func (s *Statement) genAddColumnStr(col *core.Column) (string, []interface{}) {
quote := s.Engine.Quote
sql := fmt.Sprintf("ALTER TABLE %v ADD %v;", quote(s.TableName()),
col.String(s.Engine.dialect))
return sql, []interface{}{}
}
s.TableName()函数读不出表名

Is your version the latest xorm?

更新之后，故障依旧
