From: Ken Bloom Date: 2006-10-09T23:50:14+09:00 Subject: [ANN] SqlStatement 1.0.0 - hide the syntax of SQL behind familiar ruby syntax sqlstatement - Generate complex SQL statements programmatically The main goal of this library is to be able to construct an SQL statement from "slices" that concern different aspects of the final query (perhaps in different places in your code) and then combine them all together into one statement easily. Another important goal of this library is to give some consistent Ruby syntax to three statements (INSERT, SELECT, and UPDATE) that seem to have different enough syntax that one has two write different code to generate each kind of statement. I use my SQL database (specifically MySQL) largely as a bulk data processing engine, by doing INSERT...SELECT or CREATE TABLE...SELECT statements. This library is intended to make that kind of coding easier. I expect that Object Relational mappers (such as ActiveRecord) are more useful for most people, who are performing queries and inserting/updating/querying for individual records. I have nevertheless added INSERT...VALUES statements, and will add other statements soon, for consistency. This library is inspired by CLSQL for Common LISP, or SchemeQL for Scheme, although it is very different from these two libraries. Scheme and LISP‘s use of s-expressions make it very easy to construct an entire sublanguage for the WHERE clause, simply by list parsing. The Criteria library for Ruby has attempted this, but in a more limited manner than SchemeQL or CLSQL. My library aims to cover much of the functionality in these libraries. This library doesn‘t try to abstract out the limitations of your DBMS, and I think that the SQL it uses should be fairly portable, in large measure because it hasn‘t attempted to deal with serious CREATE TABLE statements, where a lot of syntax concerning types, keys and sequences is much more variable. This library can be downloaded from http://rubyforge.org/projects/sqlstatement/ Its rdoc documentation is online at http://sqlstatement.rubyforge.org/ License: BSD license -- Ken Bloom.
