Creating stored procedure and SQLite

Question

Is it somehow possible to create a stored procedure  when using SQLite

User · Answer

Yet  it is possible to fake it using a dedicated table  named for your fake-sp  with an AFTER INSERT trigger  The dedicated table rows contain the parameters for your fake sp  and if it needs to return results you can have a second  poss  temp  table  with name related to the fake-sp  to contain those results  It would require two queries  first to INSERT data into the fake-sp-trigger-table  and the second to SELECT from the fake-sp-results-table  which could be empty  or have a message-field if something went wrong

If you are still interested  Chris Wolf made a prototype implementation of SQLite with Stored Procedures   You can find the details at his blog post  Adding Stored Procedures to SQLite

Answer  NO  Here s Why     I think a key reason for having stored procs in a database is that you re executing SP code in the same process as the SQL engine  This makes sense for database engines designed to work as a network connected service but the imperative for SQLite is much less given that it runs as a DLL in your application process rather than in a separate SQL engine process  So it makes more sense to implement all your business logic including what would have been SP code in the host language   You can however extend SQLite with your own user defined functions in the host language  PHP  Python  Perl  C   Javascript  Ruby etc   You can then use these custom functions as part of any SQLite select update insert delete   I ve done this in C  using DevArt s SQLite to implement password hashing
