Question

如果未在“insert”语句中使用，则以下查询可正常工作。使用“insert”语句，我收到错误“basis.sql_text：indvalid identifier”。我似乎无法弄清楚为什么。想法？

with basis as
          (SELECT DISTINCT
                  b.snap_id,
                  c.begin_interval_time,
                  c.end_interval_time,
                  a.sql_id,
                  b.executions_delta,
                  DECODE (d.command_type,

Answer 1

排序依据在嵌套插入查询中不起作用，请将其删除。

Answer 2

您的查询中存在少量错误。

1.使用解码或任何数据库功能时，在With basis{}内提供适当的别名

e.g。

 DECODE (command_type,
         1, 'Create_Table',
         2, 'Insert',
         3, 'Select',
         6, 'Update',
         7, 'Delete',
         26, 'Lock Table',
         35, 'Alter Database',
         42, 'Alter Session',
         44, 'Commit',
         45, 'Rollback',
         46, 'Savepoint',
         47, 'Begin/Declare',
         command_type
        )cmdtype,

和

DBMS_LOB.SUBSTR (d.sql_text, 256, 1) sql_tex

2. basis.exec_per_snap内部没有定义基础块

Answer 3

试试这个：

INSERT INTO sdhoste.EMSDB_USAGE@DEVSDB1
WITH basis AS
(basis query here)
  SELECT basis.snap_id
       , basis.begin_interval_time
       , basis.end_interval_time
       , basis.sql_id
       , NVL (basis.executions_delta, '0')
       , basis.command_type
       , basis.object_owner
       , t.table_name
       , basis.object_type
       , basis.sql_text
    FROM dba_tables@DEVSDB1 T LEFT JOIN basis 
                              ON basis.table_name = t.table_name
   WHERE OWNER IN ('EG', 'WV90');

不要将WITH子句放在parens中。

insert语句with with子句无效标识符oracle
