MySQL设置数据库隔离级别
可以通过命令行设置全局 或 会话的隔离级别。重启或者退出会话失效
SET [SESSION | GLOBAL] TRANSACTION ISOLATION LEVEL {READ UNCOMMITTED | READ COMMITTED | REPEATABLE READ | SERIALIZABLE}
具体命令
# 设置全局隔离级别
set global transaction isolation level REPEATABLE READ;
set global transaction isolation level READ COMMITTED;
set global transaction isolation level READ UNCOMMITTED;
set global transaction isolation level SERIALIZABLE;
#设置会话隔离级别
set session transaction isolation level REPEATABLE READ;
set session transaction isolation level READ COMMITTED;
set session transaction isolation level READ UNCOMMITTED;
set session transaction isolation level SERIALIZABLE;
通过配置文件设置隔离级别
[mysqld]
transaction-isolation = REPEATABLE-READ
transaction-isolation = READ-COMMITTED
transaction-isolation = READ-UNCOMMITTED
transaction-isolation = SERIALIZABLE
查看隔离级别
SELECT @@GLOBAL.transaction_isolation
SELECT @@SESSION.transaction_isolation
show variables like '%iso%';
从官方文档粘贴下来的命令可能是因为格式原因执行就报错 ,气哭 (╬◣д◢)
