Cloning a MySQL database on the same MySql instance

狂风中的少年 提交于 2019-11-27 05:58:05
I would like to write a script which copies my current database sitedb1 to sitedb2 on the same mysql database instance. I know I can dump the sitedb1 to a sql script: mysqldump -u root -p sitedb1 >~/db_name.sql and then import it to sitedb2 . Is there an easier way, without dumping the first database to a sql file? Greg As the manual says in Copying Databases you can pipe the dump directly into the mysql client: mysqldump db_name | mysql new_db_name If you're using MyISAM you could copy the files, but I wouldn't recommend it. It's a bit dodgy. Integrated from various good other answers Both

Does Scala AnyRef.clone perform a shallow or deep copy?

让人想犯罪 __ 提交于 2019-11-27 03:54:27
问题 In Scala, does AnyRef.clone perform a shallow or deep copy? 回答1: Short answer : shallow. Not-so-short answer : Unless it's overridden, AnyRef.clone() uses the Java's Object.clone() as its implementation. Javadoc on Object.clone(): The method clone for class Object performs a specific cloning operation. First, if the class of this object does not implement the interface Cloneable, then a CloneNotSupportedException is thrown. Note that all arrays are considered to implement the interface

This question already has an answer here: Deep cloning objects 45 answers Let's say that I have a class: class obj { int a; int b; } and then I have this code: obj myobj = new obj(){ a=1, b=2} obj myobj2 = myobj; Now the above code makes a reference to the first obj. What I want is that myobj2 refers to a copy of the myobj with changes not being reflected in the original. I have searched SO and the solutions thus far seems complicated. Is there an easier way to do this. I am using .net 4.5 Farhad Jabiyev Properties in your object are value types and you can use the shallow copy in such

What is wrong with this clone()?

问题 I have written this clone method for when the parent of the Employee class is abstract and the clone() method in the parent class is abstract.I wanted to copy the primitive data type of the Employee's object with this code instead of copying each primitive data type individually, but this code has problem with the line that I call clone() method. (This code is in Employee class) public Object clone() { Object obj = new Object(); Object object = obj.clone(); //Emphasis here return object; }
