環(huán)境：
數(shù)據(jù)是由用戶test1導出，對應的表空間是test1
導入時是用戶test2, 對應的表空間是test2
操作：
導入時如果目標環(huán)境中有test1表空間就會導入到test1表空間中
而如果目標環(huán)境沒有test1表空間，就會導入test2用戶的默認表空間
默認表空間查看方法：select username,default_tablespace from dba_users where username = 'SCOTT';

[Msg] Finished - Unsuccessfully
方案：語句錯誤，檢查報錯位置的語法
1.通常是格式，例如是',;等的原因
2.可能是oracle和mysql之間的數(shù)據(jù)相互導，導致字段類型不支持

[Err] 1171 - All parts of a PRIMARY KEY must be NOT NULL; if you need NULL in a key, use UNIQUE instead

INSERT INTO t_contractsupplier VALU
[Msg] Finished - Unsuccessfully
方案：導入和導出的用戶不同，導致函數(shù)調取時出錯
1.該錯出現(xiàn)的原因是不通版本之間相互導入數(shù)據(jù)文件導致的

導入數(shù)據(jù)庫時報錯：
[ERR] 1071 - Specified key was too long; max key length is 767 bytes

解決方案為：
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的版本有這個報錯，mysql5.0和5.7以上的版本都沒有這個錯誤
可以考慮升級版本，沒有好的解決辦法，如果有請告訴我謝謝謝

使用腳本自動備份數(shù)據(jù)庫時出現(xiàn)錯誤3167
mysql數(shù)據(jù)庫使用mysqldump報錯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'
解決辦法：
需要設置開啟狀態(tài)：
用管理員執(zhí)行如下命令：
set global show_compatibility_56=on;
查看是否開啟：
show variables like '%show_compatibility_56%';
再次查看：
select * from information_schema.global_status limit 3;

ORA開頭的是oracle數(shù)據(jù)庫報錯

[Err] DROP TABLE "PC_CORE"."B_FB_E_BLOCK_RECORD"
[Msg] Finished - Unsuccessfully
缺少判斷語句出現(xiàn)表不存在的情況就會報錯
用DROP TABLE IF EXISTS 替換 DROP TABLE

[Err] ORA-00955: name is already used by an existing object
說明表已經(jīng)有了。
