环境：
数据是由用户test1导出，对应的表空间是test1
导入时是用户test2, 对应的表空间是test2
操作：
导入时如果目标环境中有test1表空间就会导入到test1表空间中
而如果目标环境没有test1表空间，就会导入test2用户的默认表空间
默认表空间查看方法：select username,default_tablespace from dba_users where username = 'SCOTT';

[Msg] Finished - Unsuccessfully
方案：语句错误，检查报错位置的语法
1.通常是格式，例如是',;等的原因
2.可能是oracle和mysql之间的数据相互导，导致字段类型不支持

[Msg] Finished - Unsuccessfully
方案：导入和导出的用户不同，导致函数调取时出错
1.该错出现的原因是不通版本之间相互导入数据文件导致的

导入数据库时报错：
[ERR] 1071 - Specified key was too long; max key length is 767 bytes

解决方案为：
show variables like '%innodb_large_prefix%';
show variables like '%innodb_file_format%';
set global innodb_large_prefix=on;
set global innodb_file_format=Barracuda;
/----------=
[ERR] 1349 - View's SELECT contains a subquery in the FROM clause
mysql5.6的版本有这个报错，mysql5.0和5.7以上的版本都没有这个错误
可以考虑升级版本，没有好的解决办法，如果有请告诉我谢谢谢

使用脚本自动备份数据库时出现错误3167
mysql数据库使用mysqldump报错3167
The database to be backed up is named: information_schema
mysqldump: Couldn't execute 'SELECT /!40001 SQL_NO_CACHE / FROM GLOBAL_STATUS': The 'INFORMATION_SCHEMA.GLOBAL_STATUS' feature is disabled; see the documentation for 'show_compatibility_56' (3167)
The database to be backed up is named: performance_schema
select from information_schema.global_status ;

3167 - The 'INFORMATION_SCHEMA.GLOBAL_STATUS' feature is disabled; see the documentation for 'show_compatibility_56'
解决办法：
需要设置开启状态：
用管理员执行如下命令：
set global show_compatibility_56=on;
查看是否开启：
show variables like '%show_compatibility_56%';
再次查看：
select * from information_schema.global_status limit 3;

ORA开头的是oracle数据库报错
-------==
[Err] ORA-00942: table or view does not exist
[Err] DROP TABLE "PC_CORE"."B_FB_E_BLOCK_RECORD"
[Msg] Finished - Unsuccessfully
缺少判断语句出现表不存在的情况就会报错
用DROP TABLE IF EXISTS 替换 DROP TABLE

[Err] ORA-00955: name is already used by an existing object
说明表已经有了。。。
