echo $date

#定义数组

db_array=(scriptdev2 realmd mmfpm characters mangos)

#取数组无元素个数

lenArray=${#db_array[@]}

#循环列出数组元素

i=0

while [ $i -lt $lenArray ]

do

#执行备份

mysqldump -uroot -ppassw0rd --default-character-set=utf8 --opt --extended-insert=false \

--triggers -R --hex-blob -x ${db_array[$i]} > /opt/db-backup/everyday/${db_array[$i]}-$date.sql;

When would you choose InnoDB over MyISAM, and vice versa?When would you choose InnoDB over MyISAM, and vice versa?Apr 25, 2025 am 12:22 AM

The situations when choosing InnoDB instead of MyISAM include: 1) transaction support, 2) high concurrency environment, 3) high data consistency; conversely, the situation when choosing MyISAM includes: 1) mainly read operations, 2) no transaction support is required. InnoDB is suitable for applications that require high data consistency and transaction processing, such as e-commerce platforms, while MyISAM is suitable for read-intensive and transaction-free applications such as blog systems.

Indexes in MySQL are an ordered structure of one or more columns in a database table, used to speed up data retrieval. 1) Indexes improve query speed by reducing the amount of scanned data. 2) B-Tree index uses a balanced tree structure, which is suitable for range query and sorting. 3) Use CREATEINDEX statements to create indexes, such as CREATEINDEXidx_customer_idONorders(customer_id). 4) Composite indexes can optimize multi-column queries, such as CREATEINDEXidx_customer_orderONorders(customer_id,order_date). 5) Use EXPLAIN to analyze query plans and avoid
