CLSQL-Helper

A library providing a clutch of utilities to make working with clsql easier

single interface functions that make a best effort to read/write a date in (m)any formats
convert-to-clsql-date(time) and
simplified sql-expression interface
clsql-or(s), clsql-and(s) and clsql-exp which make building where expressions easier
clsql-mop help, find the primary keys of an object and query / test equality with these
A basic sql pretty printer, so that the code printed from log-database-query , which uses the clsql printer and allows easily recording queries executing on a given connection
coersion to/from clsql data types an value

db-object - class

Web Thread Safety - through dynamic connection binding

If you def-view-classes inherit from clsql-helper:db-object then they will never use stored database connections (from view-database slot) and instead will prefer the dynamic default-database.

Using with-database/with-a-database then become useful ways to interact with clsql in a multithreaded web environment.

Automatic Primary Key filling

While there is code in clsql to handle filling primary keys, I have never quite wrapped my head around it. Instead if you inherit from mssql-db-object or pg-db-object the db-objects will autofill single primary keys (from IDENTITY / SERIAL) Primary Key columns.

This is somewhat specific to how we design databases (most all tables have a single IDENTITY / SERIAL PK) and might not be applicable to all situations

Future

My company Acceleration.net is a significant contributer to clsql so I hope that some of these changes can be moved upstream eventually
