Oracle Stored Proc BLOB IN参数ORA-06502：PL / SQL：数值或值错误

Question

Oracle中的这个存储过程有什么问题？我在执行时收到errpr“ORA-06502：PL / SQL：数字或值错误”。

请存储proc，执行语句和错误。

var items = {
            "btnCmdClick1": { "name": "Menu1", "icon": "" },
            "btnCmdClick2": { "name": "Menu2", "icon": "" },
            "btnCmdClick3": { "name": "Menu3", "icon": "" },
            "btnCmdClick4": {
                "name": "Sub Menu1",
                "items": {
                    "btnCmdClick5": { "name": "Menu1" , "icon": "" },
                    "btnCmdClick6": {
                        "name": "Sub Sub Menu",
                        "items": {
                            "btnCmdClick7": { "name": "Menu1", "icon": "" },
                            "btnCmdClick8": { "name": "Menu2", "icon": "" },
                            "btnCmdClick9": { "name": "Menu3", "icon": "" }
                        }
                    },
                    "btnCmdClick10": { "name": "Menu3", "icon": "" }
                }
            },
            "btnCmdClick11": {
                "name": "Sub Menu2",
                "items": {
                            "btnCmdClick12": { "name": "Menu1", "icon": "" },
                            "btnCmdClick13": { "name": "Menu2", "icon": "" },
                            "btnCmdClick14": { "name": "Menu3", "icon": "" }
                }
            }
        };
