测试的时候比较重要,我们可以知道当前交易影响了哪些表
--用于记录用户在当前表上什么时候、做的什么操作:update、insert、delete
create table TriggerRecord
(
operdt datetime, --触发时间
opertp varchar(10), --操作类型:update、insert、delete
opertb varchar(50) --表名
)
--这个表于用保存生成的触发器语句,在过程中循环执行
--因为Sqlserver不允许在一个批次同时执行多条create trigger语句
create table T(sqlTrigger varchar(500))
--循环执行存于表中触发器的存储过程
create proc loopExecTrigger

declare cur cursor for select sqlTrigger from T
open cur
fetch cur into @sql
while @@fetch_status=0

--用于生成插入语句的触发器,并将触发器语句保存到表中

--用于生成删除语句的触发器,并将触发器语句保存到表中
select 'insert into T values(''create trigger T_'+name+'_D on '+name+' for delete as insert into TriggerRecord values(getdate(),''''delete'''','''''+name+''''');'')' from sysobjects where type='U' and name not in('T','TriggerRecord')
--将以上生成的语句拷贝出来执行
--执行通过上面语句生成的语句后,再执行存储生成触发器的存储过程
exec loopExecTrigger
--生成删除全部以T开头的触发器的语句

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
