Question

我必须创建一个过程，插入特定发票的行项目（产品代码）和数量。该程序只能采用4个参数 - 发票x，行项目y，产品代码z和数量w。

create or replace procedure line_item(x in number,
                                      y in number,
                                      z in VARCHAR2,
                                      w in number)
as
begin

  insert into lab9_line (inv_number, line_number, p_code,
                         line_units, line_price, line_total) 
  values(x, y, z, w, 0, 0);

end;
/

当我调用该函数时：

call procedure LINE_ITEM(6666,1,0666-SA,6,6.66,6.66);

我收到错误：

Error report -
SQL Error: ORA-06576: not a valid function or procedure name
06576. 00000 -  "not a valid function or procedure name"
*Cause:    Could not find a function (if an INTO clause was present) or
           a procedure (if the statement did not have an INTO clause) to
           call.
*Action:   Change the statement to invoke a function or procedure

EXEC语法的正确应用如下：

EXEC LINE_ITEM(6666,1,'0666-SA',6,6.66,6.66);

或使用匿名PL / SQL块：

BEGIN
    LINE_ITEM(6666,1,'0666-SA',6,6.66,6.66);
END;
/

请注意，您还要向程序传递太多参数......

为什么在调用程序时出现ORA-06576？
