为什么这会返回SQL命令没有正确结束？

Question

为什么在查询下面返回SQL错误：ORA-00933：SQL命令未正确结束。

INSERT INTO SYNC_MASTERS_TO_PS(
          MASTER_CD, 
          LANG_CD, 
          TABLE_NAME, 
          PS_CD 
         ) 
SELECT 27542003, 
     99, 
     m_office_types, 
     a.ps_cd 
    FROM (SELECT DISTINCT PS_CD 
      FROM M_POLICE_STATION 
     WHERE STATE_CD = 27) 
     AS a 

Answer 1

假设m_office_types是一个变量，你定义的地方，你必须从表的别名删除AS：

用单引号

INSERT INTO SYNC_MASTERS_TO_PS(
          MASTER_CD, 
          LANG_CD, 
          TABLE_NAME, 
          PS_CD 
         ) 
SELECT 27542003, 
     99, 
     m_office_types, 
     a.ps_cd 
    FROM (SELECT DISTINCT PS_CD 
      FROM M_POLICE_STATION 
     WHERE STATE_CD = 27) 
     a 

Answer 2

突出显示的查询（粗体）仅返回一列，（斜体）的一部分，你需要添加m_office_types输出查询（粗体）你是提取查询多个列。

INSERT INTO SYNC_MASTERS_TO_PS（MASTER_CD，LANG_CD，TABLE_NAME PS_CD）SELECT 27542003,99，m_office_types，a.ps_cd FROM（SELECT DISTINCT PS_CD FROM M_POLICE_STATION WHERE STATE_CD = 27），为
