, you need to add the Postgre error code. This is a sad story.
It can be seen that the custom error codes of databases are unreliable and they are independent of each other. You may wonder why these database vendors cannot coordinate and unify the error codes? The ideal is full, and the reality is very skinny. In a specific database, four or five different internal error codes may be defined to indicate lock conflicts. An error code cannot meet the re
information is sent from the source machine to the target machine. The mechanisms used include connection establishment and timeout retransmission. What does UDP mean by being unreliable or unreliable? I just want to send it to you. If you cannot receive it, it will be irrelevant to me.Third, the main protocol at the network layer is the IP protocol, and the network layer is the network interconnection. What does it mean to provide connections between hosts, and this connection is based on IP a
COM and COM + components, but it is separate and distinct from COM. this has fueled doubts as to whether COM and COM + will continue as "first-class" supported programming models in Microsofts product line (See Don Boxs article ,"House of COM, "In the December 2000 issueMSDNMagazine on how the new CLR environment differs from the COM environment ).
Microsofts support for components has a long history, driven in part by the fact that it provides the principal visual IDE for Microsoft developers
A new study shows that the choice of songs you listen to during driving may affect your driving safety. A fast-paced concert accelerates the heartbeat rate, causing drivers to focus their attention on music and tend to keep accelerating to keep up with the pace of music. The study points out that different types of music have different effects on drivers and men.
When listening to hip hop music, female drivers are more arrogant and accelerated than male drivers. Men are the fastest in terms o

The problem is that intel's cpu consumption has been reduced in the past two years, and its performance has not improved significantly. This is related to the architecture and the computing power provided at the same frequency is basically equivalent. The gap is power consumption.
4-core, 2.5 GB, second-level cache, 45nm, 12 m, what is the cost? The i5 configuration is sold for 155, isn't it expensive?
Not powerful yet? There are also dozens of 3G clock speed instances waiting for
you can see the font name is LTHYSZK. It may be that the font name is changed by the MIUI system to the expiration of the Arial map of unity to Andriod. There are several Chinese font files in the MIUI system with the high version number. Among them The size of the Droidsansfallback.ttf becomes 4.4M, and the font name found in unity is already droid Sans fallback, it is obvious that unity's Arial map to Andriod is actually related to the font name. (did not test the high version of the TTF t

The designers are very good. It makes developers very skinny and over-designed. In fact, changes to many application requirements are inevitable, which is also the concept of the next generation of so-called eXtreme Programming. Of course, I am only trying to judge the tool. To implement the concept, you also need to study specific operations and tools. To adapt to changes, we should adjust the original tools. Using Dynamic scripts at the action level
Do not build a high-end server in the sand float. In the computer software field, Microsoft technology is the biggest sand float. Fifteen years ago, when I wrote a hello WorldProgramI can say it can definitely run on your computer. Today, if you ask me if the hello World Program I wrote can run on your computer? I will tell you, you 'd better give it a try. If you can run it, please let me know. You didn't hear me wrong. Yes, I don't know if the program I wrote can run on your computer. But beli

In C ++ Lambda functions, where are the parameters stored when the function parameters are captured by means of replication?
I thought it was wrong in the stack.
With this question, write a recursive function and name the address of the parameter.
ReferenceCodeAs follows:
# Include # Include Void Fun2 (STD: function Void ()> Callback) {(callback )();} Void Fun1 ( Int N ){ If (N 0 ) Return ; Printf ( " Stack address = % P, " , N); fun2 ([N] () {printf ( " Capture address = % P
