我想在oracle 11g中使用以下过程动态地将序列重置为1。在oracle 11g中的重置序列

create or replace 
procedure reset_sequence(p_seq in varchar2) 
is 
    l_value number; 
begin 

-- Select the next value of the sequence 

    execute immediate 
    'select ' || p_seq || 
    '.nextval from dual' INTO l_value; 

-- Set a negative increment for the sequence, 
-- with value = the current value of the sequence 

    execute immediate 
    'alter sequence ' || p_seq || 
    ' increment by -' || l_value || ' minvalue 0'; 

-- Select once from the sequence, to 
-- take its current value back to 0 

    execute immediate 
    'select ' || p_seq || 
    '.nextval from dual' INTO l_value; 

-- Set the increment back to 1 

    execute immediate 
    'alter sequence ' || p_seq || 
    ' increment by 1 minvalue 0'; 
end; 
/

但是,当我试图执行重置序列circle_seq的过程中,我收到以下错误

BEGIN reset_sequence(vf_circle_seq); END; 

        * 
ERROR at line 1: 
ORA-06550: line 1, column 22: 
PLS-00357: Table,View Or Sequence reference 'CIRCLE_SEQ' not allowed 
      in this context 
ORA-06550: line 1, column 7: 
PL/SQL: Statement ignored 

什么是错误的代码?这在oracle 11g中是不可能的,因为在它工作正常之前,我在oracle 10g中使用了相同的代码。

尝试'BEGIN reset_sequence( 'vf_circle_seq')通过; END;' – haki

是的。它运行良好。我犯了错误。谢谢! – Mohan

序列名称应为一个字符串

BEGIN 
    reset_sequence('vf_circle_seq'); 
END;
