[ANN] Drift DB
Drift DB is a clojure database library focused on migration functions. With Drift DB you can create tables, drop tables, add columns to tables, remove columns from tables, query tables, and, though it is not the focus of Drift DB, you can insert, update, delete and select rows from tables. The only databases currently supported are H2 and Mysql. However, Drift DB uses a protocol to abstract out database specific code. All you would have to do to support other databases is implement the Drift DB protocol for it. Drift DB, like Drift, was originally a part of Conjure. However, I had several requests to separate out the function into their own library. Drift DB is not supposed to be a replacement for ClojureQL or Korma. Instead, Drift DB is focused on table altering and other tasks usually done in Drift migrations. Such tasks are currently not well supported in any other Clojure database library. All of the code for Drift DB can be found on github at: http://github.com/macourtney/drift-db Drift DB on Clojars: Drift DB Core: http://clojars.org/org.drift-db/drift-db Drift DB H2: http://clojars.org/org.drift-db/drift-db-h2 Drift DB Mysql: http://clojars.org/org.drift-db/drift-db-mysql -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: Drift DB
That looks like a bug. I'll take a look at it, and get a fix in as
soon as possible.

Re: [ANN] Drift DB
Hi Matt,
working with this stuff... pretty sure I can make rake obsolete pretty soon :)
However I am struggling with the auto increment column attribute...
(create-table
:meta-entities
(integer :id {:not-null true :auto-increment true :primary-key true})
(string :name {:not-null true :unique true })
(date-time :created_at)
(date-time :updated_at))
which looks to me compliant with what your code does in the mysql flavor lib.
It yields in MySql:
CREATE TABLE meta_entities (
id int(11) NOT NULL,
namevarchar(255) NOT NULL,
created_at datetime NULL,
updated_at datetime NULL,
PRIMARY KEY(id)
)
ENGINE = InnoDB
AUTO_INCREMENT = 0
According to the AquaStudio tool I use to reverse engineer the DDL.
The trace message:
DEBUG Thread-51 2028 234732,063 drift-db-mysql.flavor ]
Create table: :meta-entities with specs: ({:not-null true, :primary-key true,
:spec-type :column, :type :integer, :name :id} {:not-null true, :spec-type
:column, :type :string, :name :name} {:spec-type :column, :type :date-time,
:name :created_at} {:spec-type :column, :type :date-time, :name :updated_at})
Looks like the :auto-increment is dropped. drift_db/core.clj at line 155 is not
selecting
it as a potential attribute of an integer field.
I'll patch it locally so I can continue to play with it.
Any reason why the id type does not accept optional attributes ? I use id auto
incremented keys
everywhere :)
Thank you,
Luc

Re: [ANN] Drift DB
Ahem, considering that I regularly alternate between MySql, Postgres and Oracle databases, I like the idea of just calling a pop menu like "Create table (full)" and let Aqua spit out the DDL in an adjacent window while having a database explorer pane on the left :) Memory becomes a pricey real estate after a certain age :) I use Eclipse/CCW for the same reason, having to navigate in a multilingual code base, I cannot see myself learning different tools for editing purposes or having to remember a significant amount of Emacs key shortcuts. For those that are screaming at me (or laughing ironically), I started using Emacs in 1981 on a DEC-20. This version was written in Teco, extending Emacs was weirder than just dealing with a few parenthesis imbrications. I suspect that some of you were not born yet or were crawling around wearing a diaper :) You will all get there eventually (now I am laughing very loudly :) Luc On Wed, 30 Nov 2011 09:54:26 +0200 Michael Wood wrote: > Hi > > On 29 November 2011 07:03, Luc Prefontaine > wrote: [...] > > It yields in MySql: > > > > CREATE TABLE meta_entities ( > > id int(11) NOT NULL, > > name varchar(255) NOT NULL, > > created_at datetime NULL, > > updated_at datetime NULL, > > PRIMARY KEY(id) > > ) > > ENGINE = InnoDB > > AUTO_INCREMENT = 0 > > > > According to the AquaStudio tool I use to reverse engineer the DDL. > > Just by the way, MySQL supports this: > > SHOW CREATE TABLE meta_entities\G > > No need to reverse engineer the DDL for the tables :) > -- Luc P.

[ANN] Drift-db version 1.1.0 released
Drift-db version 1.1.0 released Drift-db is a library and companion project to Drift which gives you a standard interface for updating databases from migrations. In version 1.1.0: 1. Added support for Postgresql 2. Added offset and order-by as parameters to sql-find 3. Added an update-column function which allows you to alter a column already on a table with out having to remove and add it. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
