Oracle - Java - 调用“SP_GET_MENU_PARENTS”时参数的数量或类型错误

Question

以下是我的 Oracle 程序。当我使用 java 调用这个过程时，它会抛出这样的错误。

CREATE OR REPLACE PROCEDURE sp_Get_Menu_Parents
(
  v_inMenuID IN VARCHAR2 DEFAULT NULL,
  cv_1 IN OUT SYS_REFCURSOR
)
AS
BEGIN

   OPEN cv_1 FOR
       SELECT MenuItemId,
              MenuItemName,
              MenuItemDisplayName,
              MenuItemDescription,
              ParentMenuItem,
              MenuLevel,
              MenuOrder,
              CreatedBy,
              CreatedOn,
              LastModifiedBy,
              LastModifiedOn,
              IsValid
         FROM MenuItems
       START WITH MenuItemId = v_inMenuID
       CONNECT BY PRIOR ParentMenuItem  = MenuItemId
         ORDER BY MenuItemId;
END;

例外是，

java.sql.SQLException: ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'SP_GET_MENU_PARENTS'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored

这是我的java代码：

CallableStatement cs = objDBConnection.getCallableStatement("{CALL sp_Get_Menu_Parents(?)}");
                    ResultSet rsDetails = null;
                    cs.setInt(1, menID);

我哪里出错了？

Answer 1

sproc 有两个参数 - 你只提供一个给 Callable 语句。

1) 把过程变成函数：

CREATE OR REPLACE FUNCTION sp_Get_Menu_Parents(IN_MENUITEMID IN MENUITEMS.MENUITEMID%TYPE) 
RETURN SYS_RECURSOR IS

  results_cursor SYS_REFCURSOR;

BEGIN

   OPEN results_cursor FOR
       SELECT t.menuitemid,
              t.menuitemname,
              t.menuitemdisplayname,
              t.menuitemdescription,
              t.parentmenuitem,
              t.menulevel,
              t.menuorder,
              t.createdby,
              t.createdon,
              t.lastmodifiedby,
              t.lastmodifiedon,
              t.isvalid
         FROM MENUITEMS t
       START WITH t.menuitemid = IN_MENUITEMID
       CONNECT BY PRIOR t.parentmenuitem = t.menuitemid
         ORDER BY t.menuitemid;

   RETURN results_cursor;

END;

2）Java：

CallableStatement cs = objDBConnection.getCallableStatement("{CALL sp_Get_Menu_Parents(?)}");
cs.setInt(1, menID);
ResultSet rsDetails = cs.executeQuery();

Answer 2

你的程序

创建或替换过程 sp_Get_Menu_Parents ( VARCHAR2 中的 v_inMenuID 默认为 NULL， cv_1 输入输出 SYS_REFCURSOR )

需要两个参数，但您只在 java 代码中提供一个。您还必须提供第二个参数SYS_REFCURSOR。
