How to empty a SQL database? -

-

I am looking for a simple way to delete all data from a database and to structure (table, connection, etc.) ..). I am using postgreSQL but I think if there is a command to do this then it is not specific to postgrads.

Thank you,

pg_dump code>. Drop the database, recreate it and load the schema.

Dump the database schema (-s tag) into one file: 

  pg_dump -s -f db.dump db-NAME

Delete the database: 

  dropdb DB-NAME

make it happy: 

  createdb DB-NAME

Reinstall the schema only: 

  pg_restore db.dump & gt; Psql DB-NAME

This should work on PostgreSQL; For this, other DBMSs can have their own devices

Edit:

For the following comments, you can use the dropdb command, And just create another database with the dump schema if everything went well, then you can leave the old database: 

  pg_dump -s -f db.dump db-NAME Created DB-New-name pg_restore db.dump & gt; Psql DB-NEW-NAME

At this point, you have full database on DB-NAME, and there is a blank schema on DB-New-NAME. After you are sure everything is okay, use dropdb DB-NAME .

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
