Question

我正在尝试在Oracle SQL Developer上的PL / SQL中填充对象关系数据库，并不断收到错误ORA-00936：缺少表达式。

我尝试了不同的修复程序，但它们均导致不同的错误。已经提供了数据库，并且INSERT语句全是我的。

结果应该正确地插入到表中，但事实并非如此，而且我对如何前进感到困惑。

这是我的插入语句

insert into albums values (disk_type('The Essential Bob Dylan', 99, '8-Jul-2016', 'Pop', 37.00, 32, 
artist_array_list(artist_type('Bob Dylan', 'Vocals'), artist_type('Bob Dylan', 'Composer')), 
albumReviews(review_type('Shawn', '24-Jul-2018', 'Wife loved it!', 5), review_type('Reuben', '2-Aug-2019', 'Great compilation of some of his most known songs', 5)), 
'Vinyl', 2, '', 11.00)
/

Answer 1

您的INSERT语句中有几个错误：

您最后缺少结尾处的)（这是编辑器突出显示匹配的括号会很有帮助的地方）
您没有artist_array_list类型，只有artist_array_type
您没有albumReviews类型的review_table_type

将所有内容整合在一起，可以完成以下工作：

insert into albums 
values (
  disk_type('The Essential Bob Dylan', 99, '8-Jul-2016', 'Pop', 37.00, 32, 
             artist_array_type(artist_type('Bob Dylan', 'Vocals'), 
                               artist_type('Bob Dylan', 'Composer')), 
             review_table_type(review_type('Shawn', '24-Jul-2018', 'Wife loved it!', 5), 
                               review_type('Reuben', '2-Aug-2019', 'Great compilation of some of his most known songs', 5)), 
             'Vinyl', 2, '', 11.00)
);

在PL / SQL ODBM中缺少insert语句的表达式？
