Question

我正在学习甲骨文，我是初学者。请解决我的以下错误。

create or replace
PROCEDURE SP_SALE_SELECT
( para1 OUT NVARCHAR2
, para2 OUT NVARCHAR2
, action IN NVARCHAR2
) AS
BEGIN
  IF action = 1 then
    Select * From VI_Sale;
  Else if action = 2 then
    Select * From VI_Sale
    WHERE SaleID = para1;
  Else if action = 3 then
    Select * From VI_Sale
    Where CustomerID = para1;
  Else if action = 4 then
    Select * From VI_Sale
    where SaleID = para1 and CustomerID = para2;
 End if;
END SP_SALE_SELECT;

错误（20,5）：PLS-00103：遇到符号“SP_SALE_SELECT”时期待以下之一：if

Answer 1

将每个Else if更改为ELSIF。此外，您不能只从PL / SQL块中的表中选择*，您需要选择一个变量。如，

create or replace
PROCEDURE SP_SALE_SELECT
( para1 OUT NVARCHAR2
, para2 OUT NVARCHAR2
, action IN NVARCHAR2
) AS
v_col1 VI_Sale.col1%type;
BEGIN
  IF action = 1 then
    Select col1 into v_col1 From VI_Sale;
  Elsif action = 2 then
    Select col1 into v_col1 From VI_Sale
    WHERE SaleID = para1;
  Elsif action = 3 then
    Select col1 into v_col1 From VI_Sale
    Where CustomerID = para1;
  Elsif action = 4 then
    Select col1 into v_col1 From VI_Sale
    where SaleID = para1 and CustomerID = para2;
 End if;
END SP_SALE_SELECT;

Answer 2

您使用ELSE IF代替ELSEFIF（无空格），因此您要创建应关闭的其他ifs。

create or replace
PROCEDURE SP_SALE_SELECT
( para1 OUT NVARCHAR2
, para2 OUT NVARCHAR2
, action IN NVARCHAR2
) AS
BEGIN
  IF action = 1 THEN
    Select * From VI_Sale;
  ElSEIF action = 2 THEN
    Select * From VI_Sale
    WHERE SaleID = para1;
  ElSEIF action = 3 THEN
    Select * From VI_Sale
    Where CustomerID = para1;
  ELSEIF action = 4 then
    Select * From VI_Sale
    where SaleID = para1 and CustomerID = para2;
 End if;
END;
