Gorm Why does open PrepareStmt perform Prepare in advance

Your Question

    db, err := gorm.Open(mysql.Open(dsn), &gorm.Config{
        PrepareStmt: true,
    })

gorm 开启 PrepareStmt，会在执行之前多执行一次 Prepare？想问下多执行一次 Prepare 和在 Execute 之前执行的 Prepare 有什么区别，这么做的目的是什么

PrepareStmt is to support https://pkg.go.dev/database/sql#Conn.PrepareContext But the driver may implement prepare at the time of query, which may cause duplication.
