Oracle PL SQL 插入语句 - ORA-01007：变量不在选择列表中

  • 772

我有一个脚本，它将满足特定条件的记录复制到临时表中。然后原始表被截断并将记录复制回来。

用于创建临时表的语句是；

create table ARCHIVE_TMP as select * from ORIGINAL_TABLE where TIMESTAMP_UPDATED < '2017-10-04'

而再次复制记录的声明是；

insert /*+ APPEND */ into ORIGINAL_TABLE select * from ARCHIVE_TMP

当脚本中执行第二行时，它会引发异常，ORA-01007: variable not in select list但如果我手动运行第二条语句，它就会按预期工作。

我已经检查用户是否具有 CREATE 和 INSERT 权限，因为之前存在问题，即权限被分配给角色而不是用户。

我也尝试过在语句中指定列名select而不是使用select *，但这没有帮助。

以下是整个脚本；

create or replace procedure TRUNCATE_EXPIRED_ARCHIVE_DATA
(
    p_retention_period      in number   := 84, 
)
as
begin
    declare

            where       table_name like '%!_A' escape '!'
                        and column_name like 'TIMESTAMP!_%' escape '!'
            group by    owner, table_name, column_name, data_type

  1. Best Answer
    SelectSql := 'insert /*+ APPEND */ into ' || table_rec.owner || '.' || table_rec.table_name || ' select * from REODT_PROD.ARCHIVE_TMP';
execute immediate SelectSql into InsertedCount;

    是INSERT（而不是SELECT），所以您不想有一个INTO子句。

    您可以简化该过程以：

    create or replace procedure TRUNCATE_EXPIRED_ARCHIVE_DATA
(
    p_retention_period      in number   := 84
)
as
  TABLE_NOT_FOUND EXCEPTION;
  RetentionDt     date := add_months(TRUNC(sysdate), -p_retention_period);
  ExpiredCount    number := 0;
  InsertedCount   number := 0;

  PRAGMA EXCEPTION_INIT(TABLE_NOT_FOUND, -942);
begin
  for table_rec in (
    select      owner, table_name, column_name, data_type
    from        all_tab_columns
    where       table_name like '%!_A' escape '!'
    and         column_name like 'TIMESTAMP!_%' escape '!'
    order by    table_name, column_name
  ) loop
    -- Check if there are any expired records...
    execute immediate
         'select count(*)'
      || ' from "' || table_rec.owner || '"."' || table_rec.table_name || '"'
      || ' where "' || table_rec.column_name || '" < :1'
      INTO ExpiredCount
      USING RetentionDt;
    IF ExpiredCount = 0 THEN
      DBMS_OUTPUT.PUT_LINE(
        '"' || table_rec.owner || '"."' || table_rec.table_name || '" Not found'
      );
      CONTINUE;
    END IF;
    BEGIN
      execute immediate 'drop table REODT_PROD.ARCHIVE_TMP';
    EXCEPTION
      WHEN TABLE_NOT_FOUND THEN
        NULL;
    END;
    execute immediate
         'create table REODT_PROD.ARCHIVE_TMP as'
      || ' select * from "' || table_rec.owner || '"."' || table_rec.table_name || '"'
      || ' where "' || table_rec.column_name || '"'
      || ' >= TIMESTAMP ''' || TO_CHAR(RetentionDt, 'YYYY-MM-DD HH24:MI:SS') || '''';

    InsertedCount := sql%rowcount;
    commit;

    if InsertedCount > 0 then
      execute immediate 'truncate table "' || table_rec.owner || '"."' || table_rec.table_name || '"';
      execute immediate
           'insert /*+ APPEND */ into "' || table_rec.owner || '"."' || table_rec.table_name || '"'
        || ' select * from REODT_PROD.ARCHIVE_TMP';
      commit;
    end if;
  end loop;
end;
