Question

当我使用以下查询时，我收到ORA-00933错误

SELECT * FROM sales PIVOT (sum(quantity) FOR color IN ('WHITE','DARK'));

这里我的表格描述如下：

CREATE TABLE SALES(
ITEM_NAME CHAR(20) NOT NULL,
COLOR CHAR(20) NOT NULL,
CLOTHES_SIZE CHAR(10) NOT NULL,
QUANTITY INTEGER NOT NULL
);

，测试数据为：

SKIRT DARK SMALL 2
SKIRT DARK MEDIUM 5
SKIRT DARK LARGE 1
SKIRT PASTEL SMALL 11
SKIRT PASTEL MEDIUM 9
SKIRT PASTEL LARGE 15
SKIRT WHITE SMALL 2

Answer 1

The PIVOT operator was introduced in Oracle 11gR1。您的查询在该版本或更高版本中正常工作。在早期版本中，您将收到该错误：

SQL> SELECT * FROM sales PIVOT (sum(quantity) FOR color IN ('WHITE','DARK'));
SELECT * FROM sales PIVOT (sum(quantity) FOR color IN ('WHITE','DARK'))
                          *
ERROR at line 1:
ORA-00933: SQL command not properly ended

因此，您似乎没有使用支持该运营商的版本。在早期版本中，您可以使用聚合和案例语句手动执行相同的任务：

select item_name, clothes_size,
  sum(case when color = 'WHITE' then quantity end) as white,
  sum(case when color = 'DARK' then quantity end) as dark
from sales
group by item_name, clothes_size
order by item_name, clothes_size;

Answer 2

我认为您需要使用带有数据透视的子查询，例如：

SELECT * FROM (
     select * from sales
)
PIVOT
(
     sum(quantity)
     FOR color IN ('WHITE','DARK')
);

ORA-00933：使用pivot时SQL命令未正确结束
