As an additional benefit, it will also put together the data which is fragmented in the database file – if you inserted or updated the data in various tables, the data is saved in different places. This command will rebuild the database file and repack it to occupy the minimal amount of disk space.

If you want the SQLite to free up the drive space by shrinking the database file, here is the command for you: VACUUM web SQL client in Docker Very - Very fast speed small size SQL.BanD from for Enterprises. This is because the data is not removed from the disk itself, they are simply marked as removed and the engine is not taking care of them anymore. My database file is big…Įven if you remove all of your data from the SQLite database, the database file will not change the size. Simple, isn’t it? In the SQLite it will work fast enough and it will do what it should. This means that if you want to remove all data from the table use: DELETE FROM The deleted data is not saved to the logs. But on the other hand, there is also no operation log as in “big SQL engines”.
#Drop table sqlite browser how to#
This is why I’m using truncate to deal with not important data So, how to truncate in SQLite? So, if the delete is safer, why would I use truncate? Mostly for the sake of performance – the delete operation takes longer, especially if there is serious amount of data to remove.
On the other hand, truncate removes the data and in the logs, there is only the information that such an operation took place.
Note that the DROP TABLE command deletes the table and all of its. In case of any issue, the operation can be reverted by the engine. For example, the Firefox browser also uses the SQLite database internally as do many. database name is always unique and it is case-sensitive. You just have to delete the file manually. What is the difference between truncate and delete? In the databases such as MySQL, Postgres or Oracle, the delete operation saves all of the removed data to the logs. SQLite Drop Database Like most relational database systems, SQLite does not use the DROP DATABASE command to drop a database and there is no special syntax or steps to drop the database in SQLite. Surprisingly there is no truncate statement in the SQLite. In most cases, however, I only want to get rid of data but leave the empty table in place. Of course, if the table is no longer needed, I can delete the whole table. In the typical engine such as MySQL or Postgres, once the data is not needed anymore I use truncate to remove the data from the table. In some of my projects, the database tables are getting bigger and bigger. What is most important for me – it is easy to use and it only takes a file copy to perform the database backup. The database engine is fast, small and serves well for small amounts of data. For my pet projects, I’m using SQLite a lot. To drop a table from a SQLite3 database using python invoke the execute () method on the cursor object and pass the drop statement as a parameter to it.
