You probably want another gem: arel. Use that to generate SQL using Ruby. This gem only generates SELECT and WITH (ie CTE) statements/expressions.
UserQuery generates SQL WHERE clauses from a simple user query expression. Can integrate with ActiveRecord or be used stand-alone.
From http://edgeguides.rubyonrails.org/active_record_migrations.html#types-of-schema-dumps: There is however a trade-off: db/schema.rb cannot express database specific items such as triggers, stored procedures or check constraints. While in a migration you can execute custom SQL statements, the schema dumper cannot reconstitute those statements from the database. If you are using features like this, then you should set the schema format to :sql. No longer is this the case. You can now use the default schema format (:ruby) and still preserve your check constraints.
This is a custom gem that extends ActiveRecord to enable the expression of SQL `INSERT INTO ... SELECT ...` queries in a more convenient way. It allows you to copy data from one table to another based on specified conditions using a simple and expressive syntax.
This is implemented as an "external DSL" in Ruby; that is (like SQL for example), a "program" in a Ruby string is passed into some kind of parser/interpreter method. In this case, it is possible to use the result "as is" or to convert to an ordinary Ruby regular expression. Though this mini-language was conceived and implemented "for Ruby, using Ruby," in principle there is no reason it might not also be implemented in other languages such as Python or Perl. Development on this project began in mid-July 2013. As such, it is still an immature project. Syntax and semantics may change. Feel free to offer comments or suggestions.
