Sql 我想将查询存储到一个新表中；怎么做？

您尚未为

SUM（SAL）

指定列别名，但新表中的列需要名称。尝试为该表达式指定别名，例如

SUM\u SAL

SQL> CREATE TABLE temp1
  2  AS
  3       SELECT deptno,
  4              job,
  5              SUM (sal),
  6              CASE GROUPING_ID (deptno, job)
  7                 WHEN 1 THEN 'dept_totalsal'
  8                 WHEN 2 THEN 'job_totalsal'
  9                 WHEN 3 THEN 'grandtotal'
 10              END
 11                 AS subtotal
 12         FROM emp e
 13     GROUP BY CUBE (deptno, job)
 14     ORDER BY deptno ASC;
            SUM (sal),
            *
ERROR at line 5:
ORA-00998: must name this expression with a column alias
