Use the timer () open the timer, executes the timer events. Want to do something regularly, the code is written in the timer event

CodePudding user response:

Within the prescribed time to trigger an event

CodePudding user response:

Fixed to a specific some Suggestions for a few minutes, or choose database operations to achieve better

SQL SERVER called homework
ORALCE called JOB
The same meaning

CodePudding user response:

PB is written on the time the timer events

The database
Write in SQL SERVER work
ORALCE called JOB

The operating system
The WINDOW to write in the project task
UNIX write in crontab

CodePudding user response:

Upstairs positive solution,

The

reference 4 floor response:

PB written in time for the timer event

The database
Write in SQL SERVER work
ORALCE called JOB

The operating system
The WINDOW to write in the project task
UNIX write in crontab

More comprehensively, also almost
DOS can be written in C or ASM memory-resident program, according to the clock.
