语法没错误，可以建立成功。在执行的时候到Goodsname的时候若是输入int型，则插入成功，否则报错：

说明：对主子表进行插入，主键为Goodsid自增长，所以在插入子表的时候必须获取主表的系统分配ID，用了一个全局变量@@identity获取
这段代码的数据转换部分我还不敢确定是否正确，如果不进行转换，则跟更新报一样的错误，但是转换也会报错：
（所影响的行数为 1 行）
服务器: 消息 245，级别 16，状态 1，过程 proc_InsertPtoPinfoAndPdetail，行 24
将 varchar 值 'insert goodsdetail_book(GoodsID,MarketPrices,StockPrice,GoodsImg0)
values(' 转换为数据类型为 int 的列时发生语法错误。
似乎将整句当成一个字符串处理。
