ORACLE application optimization: Please avoid SQL processing in a large number of cyclic logic, oracle Optimization I encountered a case a while ago: a colleague said that a previously running package was suddenly much slower than before and the execution time was very long, in the evening, the job calls this package and does not run data for several hours. So I located an SQL statement in a stored procedure in the package during the tracking and opti

SQL execution time within the cursor takes 2 seconds, previously only 30 cycles, then the SQL needs to be 2*30=60 seconds, if the number of cycles suddenly increases to 8,000 times, 2*8000=16000 seconds, this is a few hours of time. As you can imagine, this performance suddenly drops to an intolerable level! So how to optimize it? Reduce the number of cycles, of course. After a careful look at this SQL, figuring out the business logic of the man who

Logic tag Library This tag library can be divided into three types: condition, loop, and forwarding/redirection. I.) Condition Type Logic: Empty and logic: notemptyLogic: the empty label determines whether the script variable is null, whether it is an empty string (the length is 0), whether it is an empty collection or map (call the isempty () method to determi

This article mainly introduces how to use the business logic of CodeIgniter controller, and analyzes the related concepts and specific usage of the business logic in the form of instances, for more information about the business logic of CodeIgniter controller, see the following example. We will share this with you for your reference. The details are as follows:

From: http://www.cnblogs.com/kakaku/articles/1312826.html 1. cyclically traverse the ArrayUse Logic: iterate> Tags can be used to traverse arrays. The following is an example.Code: String [] testarray = {"str1", "str2", "str3 "}; Pagecontext. setattribute ("test", testarray ); %> Logic: iterate Id = "show" name = "test"> Logic: iterate > In the code above,

In UWP, how does one uniformly process the page rollback logic between different devices? I haven't written a blog to record my learning experience for a while. It seems a bit embarrassing to recall that some things have been done during this period. So far, it has been time for me to accept and enrich myself. In this article, the author intends to tell UWP developers a realistic problem that is frequently encountered during development:Page rollback

User Experience Design The work should not only be involved at the beginning of the project, but many experience designs should be put in front of the underlying design. This is a cyclical iteration process, but what comes before this process should be the interaction process design used by users. 1. "Some underlying logical relationships are still being considered. do not consider interaction design for the moment." and "the underlying logical architecture determines the develop

SPRINGMVC integrated Hibernate validator for annotation-type parameter checking --Get less code and focus more on business logic 1 issue background: Parameter validation is a common problem, such as verifying that the password entered by the user is empty, that the mailbox is legitimate, and so on. However, both the front end and the backend need to verify the user input to ensure the correct

Since the release of sunflower Gantt chart, it has attracted the attention of many friends and mentioned many functional requirements, many of which focus on the provision and processing of data, our previous data was fully developed by referring to the data format of the project. However, with the development, we gradually realized that the XML format of the Project is a local application after all. Program You may encounter many problems when directly porting data to the network. Sometimes, we
