Environment: Win10, oracle10.2.1, Plsql 7.4 question: After Oracle is installed, using Plsql to connect to the database, it is always reported that "ora-12154 cannot resolve the specified connection identifier" error. Solve: 1, download the Oracle client required files, unzip it in a folder, download the address: Www.oracle.com/technetwork/topics/winsoft-085727.html 2. Copy the extracted file folder to a directory, for example: H:\instantclie

1, the primary key defined as the automatic growth identifier type In MySQL, if the primary key of the table is set to the Auto_increment type, the database is automatically assigned the primary key. For example: CREATE TABLE Customers (ID int auto_increment PRIMARY key notnull, name varchar); INSERT into customers (name) VALUES ("Name1"), ("name2"); Once the ID is set to the Auto_increment type, the MySQL database automatically assigns valu

UUID (Universally unique IDentifiers), a globally unique identifier. It is a string that identifies the storage device in the system so that it determines all the storage devices in the system. Why should I use UUID? Because the system automatically assigns device names that are not always consistent, they depend on the order in which the kernel loads the modules at startup. The same name may represent a different hard disk partition. If each partiti

use the self-increment primary key of the database. String typeString types are definitely more space-intensive than integer types, and are slower than integer type operations. My main use is MySQL, the explanation of this topic is suggested to see "high-Performance MySQL" third edition P125. I used the scheme (MySQL): Using the self-increment ID as the primary key to deal with the insertion efficiency problem, the use of UUID as a logical ID, has many advantages of the logical primary key,

ObjectiveThere is a requirement in the recent project to share entity content directly from third-party apps to our app using the content sharing features available on iOS devices from the iOS system. The general principle is this, first for our iOS app registration can open document types (file type), and then in third-party apps, if they use the sharing features provided by iOS, then you will see our app, click to share. and the specific ideas about the design and implementation of the require

Any computer language is inseparable from identifiers and keywords. The following describes the swift identifiers and keywords in detail. Identifier An identifier is the name specified for a variable, constant, method, function, enumeration, struct, class, protocol, etc. There are certain specifications for the letters that make up the identifiers. The naming rules for identifiers in swift are as follows:

Hibernate uses object identifiers (OIDs) to establish correspondence between objects in memory and records in database tables, and the OID of the object corresponds to the primary key of the database. To ensure the uniqueness and immutability of the OID, hibernate should be assigned a value for the OID. Hibernate assigns a value to the OID through the identifier generator.One, specify the identifier generat

Solution for obtaining the unique identifier of a device on ios, ios Solution In iOS 7, Apple once again ruthlessly blocks mac addresses. Now, it cannot obtain the physical addresses of iOS 7 devices. How can we identify the uniqueness of a device during development? The method provided by apple is to store some logo information through the keychain, and then let the application identify the uniqueness of the device through the saved logo information.
