使用Ruby脚本调用Oracle存储过程的示例：
1.首先创建Oracle存储过程test:
SQL> CREATE OR REPLACE PROCEDURE test(p1 in varchar2,p2 out varchar2 ) is
2 BEGIN
3 select p1|| PROCEDURE EXECUTED！ into p2 from dual ;
4 end;
5 /
Procedure created |
2.再写Ruby脚本，调用存储过程test,脚本内容如下,将脚本保存为：Call_proc_test.rb:
require dbi
db_read_str = BEGIN test(?, ?); END;
dbh = DBI.connect(DBI:OCI8:TNSDBNAME, username, password)
sth_db = dbh.prepare(db_read_str)
sth_db.bind_param(1, test:,*50) # allow for up to 50 chars
sth_db.bind_param(2, * 100) # allow for up to 100 chars
sth_db.execute
str = sth_db.func(:bind_value, 2)
puts str
dbh.disconnect |
3.检查Ruby语法错误：
C:>ruby -cw Call_proc_test.rb
Syntax OK
C:> |
4.最后执行Ruby脚本：
C:>ruby Call_proc_test.rb
test: PROCEDURE EXECUTED！
C:> |
注释：如果是Windows环境下，大家也可以通过双击Call_proc_test.rb 文件来运行Ruby脚本。
