Ruby API for calling Oracle PL/SQL procedures.
ruby-plsql gem provides simple Ruby API for calling Oracle PL/SQL procedures. It could be used both for accessing Oracle PL/SQL API procedures in legacy applications as well as it could be used to create PL/SQL unit tests using Ruby testing libraries.
NUMBER, BINARY_INTEGER, PLS_INTEGER, VARCHAR2, NVARCHAR2, CHAR, NCHAR, DATE, TIMESTAMP, CLOB, BLOB, BOOLEAN, PL/SQL RECORD, TABLE, VARRAY, OBJECT and CURSOR types are supported for input and output parameters and return values of PL/SQL procedures and functions.
ruby-plsql supports Ruby 1.8.7, 1.9.3 and JRuby 1.6.7 implementations.

ruby-plsql also provides simple API for select/insert/update/delete table operations (with Sequel-like syntax). This could be useful if ruby-plsql is used without ActiveRecord (e.g. for writing PL/SQL unit tests):
# insert record in tableemployee={:employee_id=>1,:first_name=>'First',:last_name=>'Last',:hire_date=>Time.local(2000,01,31)}plsql.employees.insertemployee# INSERT INTO employees VALUES (1, 'First', 'Last', ...)# insert many records employees=[employee1,employee2, ... ]# array of many Hashesplsql.employees.insertemployees# insert many records as list of valuesplsql.employees.insert_values[:employee_id,:first_name,:last_name],[1,'First 1','Last 1'],[2,'First 2','Last 2']# select one recordplsql.employees.first# SELECT * FROM employees# fetch first row => {:employee_id => ..., :first_name => '...', ...}plsql.employees.first(:employee_id=>1)# SELECT * FROM employees WHERE employee_id = 1plsql.employees.first("WHERE employee_id = 1")plsql.employees.first("WHERE employee_id = :employee_id",1)# select many recordsplsql.employees.all# => [{...}, {...}, ...]plsql.employees.all(:order_by=>:employee_id)plsql.employees.all("WHERE employee_id > :employee_id",5)# count recordsplsql.employees.count# SELECT COUNT(*) FROM employeesplsql.employees.count("WHERE employee_id > :employee_id",5)# update recordsplsql.employees.update(:first_name=>'Second',:where=>{:employee_id=>1})# UPDATE employees SET first_name = 'Second' WHERE employee_id = 1# delete recordsplsql.employees.delete(:employee_id=>1)# DELETE FROM employees WHERE employee_id = 1# select from sequencesplsql.employees_seq.nextval# SELECT employees_seq.NEXTVAL FROM dualplsql.employees_seq.currval# SELECT employees_seq.CURRVAL FROM dual### Usage with Rails:IfusingwithRailsthenincludeininitializerfile:
```rubyplsql.activerecord_class=ActiveRecord::Baseand then you do not need to specify plsql.connection (this is also safer when ActiveRecord reestablishes connection to database).
Install as gem with
gem install ruby-plsql
or include gem in Gemfile if using bundler.
In addition install either ruby-oci8 (for MRI/YARV) or copy Oracle JDBC driver to $JRUBY_HOME/lib (for JRuby).
If you are using MRI 1.8 or 1.9 Ruby implementation then you need to install ruby-oci8 gem (version 2.0.x or 2.1.x) as well as Oracle client, e.g. Oracle Instant Client.
If you are using JRuby then you need to download latest Oracle JDBC driver - either ojdbc6.jar for Java 6 or ojdbc5.jar for Java 5. And copy this file to one of these locations:
- in
./libdirectory of Rails application and require it manually - in some directory which is in
PATH - in
JRUBY_HOME/libdirectory - or include path to JDBC driver jar file in Java
