Working around the lack of Functions seems harder but in fact, you can program functions with Views. Variables are easy to do: create a one-row temporary table and call it args or var. The lack of Stored Procedures is usually ok-you can just use scripts. Win all round.īut sometimes you do wish you could do it in SQL. The fact that it doesn't have SQL syntax for stored procs and functions is usually not a handicap because it has an interface for the consuming application to register functions, which means you get to write your functions in your preferred programming language. The following statement creates the contacts table.SQLite is marvellous. The following database diagram illustrates tables: contacts groups, and contact_groups.
