我们如何使用 Grails 域或 GORM 截断表？

Question

I want to truncate my table named as scraper_proxies . I can truncate this table using the native SQL like below:

int truncateResult = session.createSQLQuery("TRUNCATE TABLE scraper_proxies").executeUpdate()

Requirement

But i want to truncate this table using the Grails domain named as ScraperProxies which is mapped with scraper_proxies table.

Is anyone have any idea about it?

Answer 1

Delete all ScraperProxies records in the database using the Grails domain :

Integer result = ScraperProxies.executeUpdate("delete ScraperProxies")

It will return the integer value. If it deletes the 5 rows than return value will be 5.
