Yuav ua li cas batch hloov MySQL database los ntawm MyISAM rau InnoDB cia cav?

mysql
USE 你要操作的数据库名;

Kauj ruam 2: Tsim cov nqe lus hloov dua siab tshiab

Tom ntej no, peb yuav tsum tsim cov SQL nqe lus uas hloov tag nrho MyISAM cov lus rau InnoDB cov lus.

Qhov no tuaj yeem ua tau los ntawm kev nug information_schema.tables rooj ua kom tiav.

Khiav SQL nqe lus hauv qab no:

SELECT CONCAT('ALTER TABLE ',table_name,' ENGINE=InnoDB;') 
FROM information_schema.tables 
WHERE table_schema="你要操作的数据库名" AND ENGINE="MyISAM";

Cov nqe lus no tsim ib txheej ntawm ALTER TABLE nqe lus uas hloov lub cav cia ntawm txhua lub rooj MyISAM rau InnoDB.

Kauj ruam 3: Ua raws li cov lus qhia hloov dua siab tshiab

Luam cov txiaj ntsig tau tsim hauv cov kauj ruam dhau los thiab dhau musAINws tuaj yeem pab peb yooj yim lim tawm ciam teb.

在Sib tham GPTSau cov hauv qab no:

请帮我过滤以下边框：

+--------------------------------------------------------------+
| ALTER TABLE table1 ENGINE=InnoDB;                            |

| ALTER TABLE table3 ENGINE=InnoDB;                            |
+--------------------------------------------------------------+

Tom qab ntawd, thaum khiav hauv MySQL, MySQL yuav ua cov lus ALTER TABLE nyob rau hauv ib ntu los hloov tag nrho MyISAM ntxhuav rau InnoDB cov lus.

Piv txwv

Nco ntsoov tias cov ntaub ntawv koj xav tau ua haujlwm muaj npe example_db, ua cov kauj ruam hauv qab no:

1. Xaiv database:

USE example_db;

2. Tsim cov nqe lus hloov dua siab tshiab:

SELECT CONCAT('ALTER TABLE ',table_name,' ENGINE=InnoDB;') 
FROM information_schema.tables 
WHERE table_schema="example_db" AND ENGINE="MyISAM";

3. Luam cov nqe lus tsim tawm thiab ua nws hauv MySQL:

ALTER TABLE table1 ENGINE=InnoDB;
ALTER TABLE table2 ENGINE=InnoDB;

Ceev faj

Ua ntej ua qhov kev hloov pauv batch no, muaj ob peb lub ntsiab lus kom nco ntsoov:

1. Cov ntaub ntawv thaub qab: Ua ntej ua batch hloov dua siab tshiab, nco ntsoov ua kom tiav cov thaub qab ntawm cov ntaub ntawv los tiv thaiv cov ntaub ntawv poob.

2. Kev xeem ib puag ncig: Nws yog ib lub tswv yim zoo los sim hauv qhov chaw sim ua ntej kom paub tseeb tias cov txheej txheem hloov dua siab tshiab yuav tsis cuam tshuam rau kev ua haujlwm ntawm koj daim ntawv thov.

3. Database permissions: Xyuas kom tseeb tias koj muaj cai database txaus los ua ALTER TABLE cov haujlwm.
