Tablespace information in Schema Browser includes objects in recycle bin
说明
The information listed in the Schema Browser for Tablespaces usage is not correct because it includes objects that are in the recycle bin.
解决办法
Tables that are dropped and go to the recycle bin continue to occupy space in the tablespace. If you want to free up space as you drop a table, drop it with the PURGE option. If the table is already dropped, then purge it from the recycle bin.
