如何檢查MySQL表是否爲UTF-8並具有storageEngine InnoDB？

Question

谷歌搜索只是找到從一種格式更改爲另一種格式的指示，但我似乎無法找到如何確切地確定哪些我第一次。

我怎能：

1) Check what character encoding a table has? 
2) Check what storage engine a table uses? 
3) Check if all tables are certain encoding? 
4) Check if all tables have a certain storage engine? 

謝謝！

您可以使用information_schema來了解每個表的引擎。

select table_name,engine 
from information_schema.tables 
where table_schema = 'your_database' 

的編碼，您可以使用

show create table table_name 

，或者甚至更好

select 
c.character_set_name 
from information_schema.tables as t, 
    information_schema.collation_character_set_applicability as c 
where c.collation_name = t.table_collation 
and t.table_schema = "your_db" 
and t.table_name = "table_name";
