I am trying to execute a stored procedure with ruby-oci8 gem. And I can execute normal queries but not my procedure.

# irb -r oci8
Warning: NLS_LANG is not set. fallback to US7ASCII.
irb(main):001:0> conn = OCI8.new('AAA/AAA@//10.112.68.14:1521/dptedp0')
irb(main):002:0> conn.exec("SELECT * FROM mytable"){|r| puts r.join(", ")}
1, user1, data1
2, user2, data2
irb(main):003:0> conn.exec("ALTER TRIGGER trigger_mytable_id ENABLE")
=> 0
irb(main):004:0> conn.exec("ALTER TRIGGER trigger_mytable_id DISABLE")
=> 0

until here all works fine, but when I try to execute a procedure, it didn't work.

irb(main):005:0> conn.exec("EXECUTE  reset_seq( 'mytable_id_seq', 'mytable', 'id' )")
OCIError: ORA-00900: invalid SQL statement
        from stmt.c:253:in oci8lib_191.so
        from /opt/ruby/gems/ruby-oci8-2.1.2/lib/oci8/oci8.rb:474:in `exec'
        from /opt/ruby/gems/ruby-oci8-2.1.2/lib/oci8/oci8.rb:282:in `exec_internal'
        from /opt/ruby/gems/ruby-oci8-2.1.2/lib/oci8/oci8.rb:275:in `exec'
        from (irb):9
        from /usr/bin/irb:12:in `<main>'

My procedure works well in sqldeveloper.

  execute  reset_seq( 'lrf_id_seq', 'lrf', 'id' )
  anonymous block completed

I doesn't return any value. Is it possible to execute a procedure like this with oci8 gem?

I am using: ruby 1.9.3p429 ruby-oci8 (2.1.2)

Ruby/OCI8 无法识别 EXECUTE - 您应该将调用包装在匿名 PL/SQL 块中：

require 'oci8'

conn = OCI8.new('AAA/AAA@//10.112.68.14:1521/dptedp0')
conn.exec("begin reset_seq( 'mytable_id_seq', 'mytable', 'id'); end;")
