Background: due to not update, but each time a new library to use heavy guide, large amount of data, not heavy lead time need 2 hours, later found out that the database file is very small, like a lazy way, try to copy the database files directly, didn't find any problems at the beginning, but later found abnormal data query,
I use the copy method directly copied A library, such as the library A copy A B, and then I in library operation, B
This way to check your data will be a problem, but when I first time to import data, no matter how I import the data behind, the query result is the same,

Night view of this database under the principle of one:
Knowledge Grid, Knowledge Grid, store metadata, column information, table, block of data distribution statistics, the same query cache information,

This information makes me very depressed, because I am a direct copy data files, this part information didn't update,

My question is:
1, about the knowledge network under BH_RSI_Repository file can be directly deleted, so that the original database have no influence,
2, if have, how can I make this knowledge network reconstruction


Thank you so much!
