Oracle PLSQL-FORALL立即执行

我想对forall语法使用executeimmediate，因为我想使用变量“schemasname”而不是“dcbhmoh1”。 谢谢

您可以尝试使用定义工作会话的架构

EXECUTE IMMEDIATE 'Alter session set current_schema='|| schemasname ;

像这样：

DECLARE
    schemasname varchar2(25) := 'dcbhmoh1';
    datet char(6) := '102024';

    TYPE anames IS table of dcbhmoh1.F01131M%ROWTYPE;
ar anames;

BEGIN
  -- set schema
  EXECUTE IMMEDIATE 'Alter session set current_schema='|| schemasname ;
  -- do your work  
  EXECUTE IMMEDIATE 'SELECT * FROM F01131M WHERE ZMDTI >= ' || datet BULK COLLECT INTO ar;
  dbms_output.put_line(ar.count);
  IF ar.Count > 0 THEN
    EXECUTE IMMEDIATE 'TRUNCATE TABLE F01131M';    
    FORALL i in ar.first .. ar.last INSERT INTO F01131M VALUES ar(i);    
  END IF;
END;

（不完全理解<代码> >所有< /COD> > .< /P>。您应该考虑分区表和截断/删除旧分区。

DECLARE
    schemasname varchar2(25) := 'dcbhmoh1';
    datet char(6) := '102024';

    TYPE anames IS table of dcbhmoh1.F01131M%ROWTYPE;
ar anames;

BEGIN
  -- set schema
  EXECUTE IMMEDIATE 'Alter session set current_schema='|| schemasname ;
  -- do your work  
  EXECUTE IMMEDIATE 'SELECT * FROM F01131M WHERE ZMDTI >= ' || datet BULK COLLECT INTO ar;
  dbms_output.put_line(ar.count);
  IF ar.Count > 0 THEN
    EXECUTE IMMEDIATE 'TRUNCATE TABLE F01131M';    
    FORALL i in ar.first .. ar.last INSERT INTO F01131M VALUES ar(i);    
  END IF;
END;
