Windows 8.1 single language 64 bit product key generator. 我删除了一部分数据：

1. The view editor does not consider SAPCRM as the default schema. (since it is neither the physical schema nor is it defined in the list of authoring schemas). As a result, the view editor considers the authoring schema SAPAUTH.
2. Oct 22, 2013  SequenceId Generator for Azure or any Big Table Storage. Windows Azure and some other cloud table storage systems do not support auto-increment identity columns as Microsoft Sql Server does. Azure groups records by a dual key, the partition key and the row key.
3. Synonyms define unique names (or aliases) for each object that is accessible from the server. Synonyms are useful because they hide the underlying data source location and identity from client applications. They also provide support for extended metadata features of the server, such as virtual fields and additional security mechanisms.

mysql> delete from pending_22 limit 1000;
Query OK, 1000 rows affected (2.99 sec)

但是delete是不会自动释放空间的，该表表空间大小仍然是之前的大小：30408704

想通过optimize table来释放下空间：

mysql> optimize table pending_22;

+------------------+----------+----------+-------------------------------------------------------------------+
Table Op Msg_type Msg_text
+------------------+----------+----------+-------------------------------------------------------------------+
np002.pending_22 optimize note Table does not support optimize, doing recreate + analyze instead
np002.pending_22 optimize status OK
+------------------+----------+----------+-------------------------------------------------------------------+

2 rows in set (7.49 sec)

该表是innodb类型。

解决办法：

mysql> alter table pending_22 engine=innodb;
Query OK, 8299 rows affected (6.63 sec)
Records: 8299 Duplicates: 0 Warnings: 0

再观察下其表空间大小变成了27262976。

Overwatch license key generator 2018. 注意：优化的前提是独立表空间模式（参数innodb_file_per_table为ON)，否则没有任何效果的。

对于共享表空间模式，想释放磁盘空间，请参考：http://www.voidcn.com/article/p-eebeovvx-mt.html
