使用Ruby脚本调用过程的示例:
1.首先创建过程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:如果是环境下,大家也可以通过双击Call_proc_test.rb 文件来运行Ruby脚本。
