[질문] if(now()=sysdate(),sleep(15),0)

The expression "if(now()=sysdate(),sleep(15),0)" is not a valid programming syntax in most programming languages. It seems to be a mix of SQL and a hypothetical programming language.

In SQL, the "now()" function is not typically used. Instead, you can use "CURRENT_TIMESTAMP" or "GETDATE()" depending on the database system. The "sysdate()" function is commonly used in Oracle databases to get the current date and time.

If you want to perform a conditional sleep in a programming language, you would need to use the appropriate syntax for that language. For example, in Python, you can use the "time.sleep()" function to pause the execution of the program for a specified number of seconds.

Here's an example of how you can achieve a conditional sleep in Python:

import time

if datetime.datetime.now() == datetime.datetime.today():
    time.sleep(15)
else:
    pass

This code checks if the current date and time are equal to the current day and then sleeps for 15 seconds if the condition is true.
