This article will introduce the differences between mysql 5.5 and 5.6 timestamp fields DEFAULT CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP. I hope this tutorial will be helpful to you.

The Code is as follows:

directly put into the output scheme set. If the read scheme does not have a specified attribute value, it will add all the possible schemes after this attribute value is added to the output scheme set.
The extension of the room number attribute only needs to be done once before the first "Inter-object constraint" is applied.
Use the constraints between objects to filter the extended solution set and remove the solution that does not meet the constraints. The final answer is obtained. The deriva

Set Environment Variables
Before hadoop is started, three files need to be configured.
However, before that, we need to set several environment variables similar to Windows to facilitate command-line.
Export hadoop_home =/users/Billy/hadoop
Export Path = $ path: $ hadoop_home/bin
Configure hadoop-env.sh
Under the hadoop-> conf directory, locate the hadoop-env.sh and open the Edit to make the following settings:
Export java_home =/library/Java/Home (remove comments)
Summary: In data migrate, the constraints on some tables are always bothering us, making migratet difficult. How can we use the attributes of constraints to solve these problems? This article describes in detail the four attributes of constraints: Deferrable/not deferrable, Deferred/immediate, enalbe/disable, validate/novalidate, and how to apply these attributes to cope with related problems.
1. Deferrable, not deferrable (default value)
1) This defines whether the attribute can be defer. defer

We will create someConstraintConstraints, including primary keys and Foreign keys. Does it have attributes? The answer is yes. In this article, we will introduceOracleFour attributes of database Constraint constraints: Deferrable/not deferrable, Deferred/immediate, enalbe/disable, validate/novalidate. Let's take a look at this process.
1. Deferrable, not deferrable (default value)
1) This defines whether the attribute can be defer. defer refers to the time for checking. If the check is Defer at
contraint of Deferrable is created)
A. Specify the Deferred value when creating a contraint
B. Modify statements at the session level
Set constraint (s) contraint_name/all immediate/deferred.
3) This attribute is defined when the constraint is created and cannot be modified.
4) notice: If a Deferrable uk or pk is created, only the corresponding nonuniquce index is created, and the uniquce index is not created.
2. Deferred, immediate (default value)

The next step is to fix the RNK and then find the best UK. If J is derivative of the UK
