Ii. Pre-script and Post-script
Generally, the structure changes of most data tables can be automatically completed by RedGate. All we need to do is set the default value. However, in other cases, you need to write your own scripts. Here are some examples.
1. default dataThe default data is added after the database is created. We can
Generally, the IOC implementation step is --> Create a container --> Add a component --> get a component --> use a component.ArticleThis article describes the four phases.
1. Create a containerHere, I will take a ready-made project for analysis. First, we need to build an IOC container. In the project, a container-type container is set up to be responsible for IOC container construction and component addition.CodeAs follows:
1 using system;2 using system. Collections. Generic;3 using system.
system ("cd"). Here, it mainly refers to the consumption of sub-processes in the system mode. The test1 program cannot reflect this.(2) The second consumption of 0.180000 seconds is two clock () function calls divided by clocks_per_sec.(3) The Clock () function returns a relative time instead of an absolute time.(4) clocks_per_sec is a system-Defined Macro defined by the GNU standard library as 1000000.
2) times () Time Functions
1) Overview:
The prototype is as follows:Clock_t times (struct
, int value);
The function of the parameter is the same as that of getpriority.
The value of the value is added to the default value of nice NZERO. Set this value to the new nice value.
4. Process Times)
The process time includes wall time (wall clock tie), user CPU time (user CPU time), and kernel CPU time (system CPU time ).
Function times can obtain these three time periods.
Function declaration:
#include clock_t times(struct tms *buf);

1. PrefaceTest the execution time of a program, including user CPU time, system CPU time, and clock time. Before the time is obtained before the main function of the program is implemented with the time function, this can only roughly calculate the program execution times, can not accurately get other time. When watching "Apue", the book about the program time test procedures, very formal, provide these three time. If so, search the internet for a moment and summarize it.2. How to obtainThere ar
complete the test. For example, the ARM7TDMI core provides three scanning chains.The JTAG controller consists of the Test Access Port Controller (TAP), command registers, and data registers. Among them, the TAP controller is the core controller of JTAG and requires the following five control signals: TCK (border scan clock), TMS (JTAG test mode selection), TDI (Serial border scan input data), TDO (Serial boundary scan output data), and TRST (JTAG tes

Simple programs can be implemented through commands

If the time command is not convenient, you can use system functions.

In severe cases, you need to adjust the corresponding database parameters. in Oracle, this parameter should be set to max_commit_propagation_delay> = 90000.
