![]() The package includes extensive documentation on the language and system.įind out more at our website. The JSON output allows for the creation of even more analysis or interfacing code. The full system also includes features for managing and upgrading schema, creating test code for stored procedures, getting query plans for procedures, as well as interfacing with stored procedures from other languages, such as Java and Objective-C. I think a key reason for having stored procs in a database is that youre executing SP code in the same. CG/SQL enables engineers to create highly complex stored procedures with very large queries, without the manual code checking that existing methods require. That said, you can make functions in many other languages too, depending on what you're embedding SQLite in.CG/SQL is a code generation system for the popular SQLite library that allows developers to write stored procedures in a variant of Transact-SQL (T-SQL) and compile them into C code that uses SQLite’s C API to do the coded operations. Compiling for deployment across a wide range of platforms is not easy you end up buried under fiddly detail that's just a little bit different everywhere. What you can do though is map functions from a c library to SQL functions (user-defined functions). 1 year, 5 months ago Compiling for a single platform is pretty easy. SQLite does not have a stored function/stored procedure language. those stored procedures must be locked down and accessible only to fully trained staff for modification. Industries that are governed by rules (such as FDA or Military) must ensure that all database access is by stored procedure only. 3 years, 10 months ago As an "Old-School" DBA, I can tell you that in areas that are tightly controlled, the developers are seldom allowed direct database access. It seems like it's more of a proof of concept. The readme file implies that this is not production ready, nor is it for experimentation. 6 years, 5 months ago Article is dead now, but the project is at /wolfch/sqlite-3.7.3.p1. For SQLite this is less of an imperative as it does not support client/server. Most app developers prefer to move some their business logic outside the SQL engine (obviously not the queries!). Executing business logic be it query OR interative OR conditional code inside an SP in the SQL engine can (1) improve data retrieval performance, (2) reduce network traffic (3) reduce app layer memory usage (4) cache query execution plans (precompiled SPs). 7 years, 1 month ago Most SQL engines are client/server (NOT SQLite!), For these, performance is a key issue when deciding where to put your business logic. There's plenty of other ways to prevent this attack further up the stack. ![]() I've also code reviewed insecure SPs that are vulnerable to SQL injection (typically based on dynamic SQL). ![]() CG/CQL also generates other useful artifacts for testing and. Thousands of SQL based apps have been built without them that are safe against this attack. CG/SQL is a compiler that converts a SQL Stored Procedure like language into C for SQLite. 7 years, 1 month ago Firstly, SP's existed long before SQL injection had even been thought of. There is absolutely no difference between a standard query which runs in the context of the SQL Engine, and selecting a SP. For example being able to Share the relevant queries by having them embedded in the sqlite file. Ref for /index.html/doc/trunk/There are many other reasons however. 8 years, 2 months ago Thanks for the addition. 8 years, 2 months ago You can use the SQLite equivalent of SQL CLR functions to achieve the same goal ( /questions/172735/…). I'm not saying that there is NO reason to implement SPs in SQLite - just much less reason than in other DB engines. 6 11 months ago Related Topics sqlite stored-procedures Comments 9 years, 8 months ago To clarify.
