oracle写了一个储存过程重置序列，执行时报错，详见附件，请各位帮忙看看

Question

create or replace procedure reset_seq(data_seq in varchar2) is
v_seq varchar2(1000);
begin
select 'drop sequence' || data_seq into v_seq from dual;
execute immediate v_seq;
select 'create sequence' || data_seq ||
'minvalue 1 maxvalue 999999 start with 1 increment by 1 cache 20'
into v_seq
from dual;
execute immediate v_seq;
end;

Answer 1

'drop sequence' 要加上空格，即 'drop sequence '，这样用||连接的字符串才是正确的格式。
原来的错误连接串： drop sequencetpl_pub_company_seq, 这个明显存在语法错
正确的连接串：drop sequence tpl_pub_company_seq
