I use the wizard in "Tools" (SQLiteStudio 3.2.1, circa June 2019) to import a csv file into a table. I need to repeat the task a few (5) dozen times and I want to submit a query instead of pointing and clicking each time.
Unfortunately there is no way to get these SQL statements, but there is something else that may be useful to you.
You can use SQL function available from SQLiteStudio: import()
as described at https://github.com/pawelsalawa/sqlitestudio/wiki/User_Manual#built-in-sql-functions
For example:
SELECT import('my_file.txt', 'CSV', 'target_table');
This is much easier to repeat.
