Outdated egg!

This is an egg for CHICKEN 4, the unsupported old release. You're almost certainly looking for the CHICKEN 5 version of this egg, if it exists.

If it does not exist, there may be equivalent functionality provided by another egg; have a look at the egg index. Otherwise, please consider porting this egg to the current version of CHICKEN.

ssql

Description

This extension provides a Scheme syntax for SQL. It should be considered experimental as the API is still incomplete and very much in flux. The code is located at https://bitbucket.org/DerGuteMoritz/ssql.

Authors

Original idea and implementation foundation by Peter Bex. Port to Chicken 4, addition of new features and maintenance by Moritz Heidkamp.

Documentation

To be done, see the unit tests for now.

ssql->sql

ssql->sql connection ssqlprocedure

Transforms the SSQL code (represented as list) into the SQL query (represented as string). If connection is given, it will be used to escape strings in the query. #f can be passed to the connection parameter.

(ssql->sql #f '(select (columns id title author) (from books)))

SSQL syntax

Select queries:

(select (columns id title author) (from books) (where (= id 10)))

Insert queries:

(insert (into books)
        (columns title author)
        (values #("Novaja ziamla" "Janka Kupała")
                #("Vianok" "Maksim Bahdanovič")))
