Alter table t move and alter table t shrink space can both be used for CIDR and CIDR to reduce the HWM,It can also be used to eliminate Row Chaining and Row Migration ),But there are the following differences:1) Using alter table move will contract the table to the initial size specified by the storage clause when creating the table. Using alter table shrink space is not subject to this restriction.2) After you use alter table move, the index will be

This article mainly introduces how to use method chains in Python. methodchaining is a common syntax in object-oriented programming languages, if you are interested in the method chain, refer Method chaining)It is a common syntax in object-oriented programming languages. It allows developers to call the same object multiple times when only one object is referenced. For example: Suppose we have a Foo class, which contains two methods: bar and baz. Cre

JS events based on callback mechanism(3) The SetTimeout delay time is a function of the 0,settimeout call is actually a callback embodiment(4) Chained invocation: When chaining calls, it is easy to implement chained calls in the evaluator (setter) method, while the accessor (getter) is relatively bad for chaining calls because you need the accessor to return

(dllimport) char *name;A dynamic-link library typically contains a series of functions for other programs, so the declspec (dllexport) syntax is most commonly used. If a dynamic library requires a defined global variable in another program, you need to export the variable in another program, and in the dynamic-link library you need to declare the variable as an external variable for use using extern declspec (dllexport).3. How to linkYou can link to (or load) a DLL in one of the following two w

Exposing public methods to others to expand your plugin (if required)For example, the highlight plugin has a format method to highlight the text, then we can write it as public, exposed to the plug-in users, different use of according to their own needs to rewrite the format m

(Forward mapping table).B. Hashed page Tables Hash page tableA common way to handle more than 32-bit address space is to use the Hashed page table (hash page tables)with a virtual page number as the hash value. Each entry in the hash page table includes an element of a linked list that texts hash the same location. Each element has three fields: a virtual page number, a mapped frame number, and a pointer to the next element in the linked list.Personally, the address translation of the hash page

"Editor's note" author Yegor Bugayenko is a software architect for Teamed.io, keen on software quality research and effective project management approach exploration. In this article, Yegor discussed the issue of "exception caught but not re-thrown" and shared some suggestions.It's a common and very popular mistake to just catch an exception and not re-throw it anti-pattern. But there's no doubt that in all exception capture code, it's basically everywhere, as in this code: try{ stream.w

', width:'150px' }); }); Note that by default, all HTML elements have a static location and cannot be moved. To operate the position, first set the CSS position attribute of the element to relative, fixed, or absolute! 5. stop MethodThe stop () method is used to stop an animation or effect before they are completed. The stop () method applies to all jQuery effect functions, including sliding, fade-in and fade-out, and custom animations. Syntax:$ (Selector). stop (stopAll, goToE

when creating or modifying it ). All cluster tables in a cluster use the storage parameters of the cluster to control their space allocation. Row Storage: Oracle uses one or more row fragments to store the first 255 columns of each row of data in the table. When Oracle must use multiple row fragments to store the same row (and each row segment is in a different data block ), this row will form a row Link (row chaining) between multiple data blocks) W

Tree B can only have a maximum of M sub-trees, a non-leaf node can have a maximum of M-1 key values. The root node subtree must be in the range of 2 ~ M. The number of child nodes of other non-leaf nodes must be in m/2 ~ M. The number of data values contained in the leaf node must be in the range of [l/2 ~ Between L. 　　Chap20: Hash Tables only support partial operations on elements, such as common insert, delete, and search operations. The hash function converts an item into a small array inde

reasoning: Forward-chaining and backward-chaining ). Positive reasoning is also called the embedding method. It is driven by facts. It starts from an initial fact and constantly applies rules to draw conclusions. First, select a rule in the Candidate queue to enable the rule for reasoning, and record the conclusion as the evidence for the next reasoning. Repeat this process until no available rules can b

Objective C # principle 14: Using constructor chainsItem 14: Utilize constructor chaining Writing constructor is a repetitive task. Many developers write a constructor first, and then copy and paste it to other constructor to satisfy some of the class's heavy-load interfaces. I hope you didn't do this. If so, stop it. Experienced C ++ProgramA secondary private method may be usedAlgorithmPut it inside to construct the object. Please stop. When you fi

time on the interface and hardly need to write code, most of the time you use Ext, you have learned how to use its APIs. However, if you want to modify the code or implementation of Ext, it is basically difficult. Jquery is not the same, it is very delicate, and the core + plug-in type development applications. you don't need to change the core. You can use plug-ins to complete the functions you need. If you don't have any plug-ins available, you can write a plug-in yourself, which is muc

out of this dimension, you may not even be aware of this restriction. However, the abstract dimensions of DSL (domain-specific language) such as SQL, HTML, CSS, and make are customized for specific fields. From these abstract perspectives, the problem is often the easiest, therefore, DSL is more convenient than general programming languages in solving problems in specific fields. Generally, non-General languages such as SQL are called external DSL (externalDSL); In general languages, we can bre

not familiar with SQL. For example, in the SQL Server dialect, the Code should express "(FOO is null or foo! = 'X ')". But by replacing this code with isnotnullor (rejectedvalue), which is easier to understand and more similar to the human language, the code is obviously more readable and the system is protected, this avoids the need to modify the initial code implementation in the future to take advantage of the facilities of another database vendor. Use Java to create an internal DSL The best

into the memory, which we do not want to see. Therefore, Oracle DBA usually uses a small block size for small and randomly accessed tables. 　　Isolate tables with lob Columns-- For tables that contain raw, long raw, or In-line lobs, moving them to large data blocks will greatly improve disk I/O performance. Experienced DBAs will check dba_tables.avg_row_len to ensure that the block size is larger than the average row size. This will reduce the occurrence of row
