SQL存储过程和触发不能使用USE的应对方法_MySQL
bitsCN.com
大家都知道在SQL的存储过程,触发中不能使用USE。
怎么办呢,当然可以直接用[databasename].[user].[tablename]这样来访问,但是某些语句必须在当前数据库下执行,比
如sp_adduser等。
之前看到一篇文章,我测试了有问题。
原文:
这里提供一个解决方案:
使用Exec(ute)语句来改变当前数据库,不过要注意的是,数据库环境的更改只在Execute语句结束前有效,所以你必须把
后面的语句和Execute放到一起。Example:
create proc test
as
exec('use pubs') exec sp_adduser 'test'
go
exec test
我自己试了一下,根据下面的语句执行没有问题:
使用Exec(ute)语句来改变当前数据库。
如下:
CREATE PROCEDURE cs
AS
BEGIN
exec('use sjdbmis; select plucode from txtplu')
END
GO
又如:
CREATE PROCEDURE cs
AS
BEGIN
exec('use sjdbmis; exec sp_adduser ''test''')
END
GO

What is cache? A cache (pronounced ka·shay) is a specialized, high-speed hardware or software component used to store frequently requested data and instructions, which in turn can be used to load websites, applications, services, and other aspects of the system faster part. Caching makes the most frequently accessed data readily available. Cache files are not the same as cache memory. Cache files refer to frequently needed files such as PNGs, icons, logos, shaders, etc., which may be required by multiple programs. These files are stored in your physical drive space and are usually hidden. Cache memory, on the other hand, is a type of memory that is faster than main memory and/or RAM. It greatly reduces data access time since it is closer to the CPU and faster compared to RAM

Git is a fast, reliable, and adaptable distributed version control system. It is designed to support distributed, non-linear workflows, making it ideal for software development teams of all sizes. Each Git working directory is an independent repository with a complete history of all changes and the ability to track versions even without network access or a central server. GitHub is a Git repository hosted on the cloud that provides all the features of distributed revision control. GitHub is a Git repository hosted on the cloud. Unlike Git which is a CLI tool, GitHub has a web-based graphical user interface. It is used for version control, which involves collaborating with other developers and tracking changes to scripts and

How to correctly use sessionStorage to store sensitive information requires specific code examples. Whether in web development or mobile application development, we often need to store and process sensitive information, such as user login credentials, ID numbers, etc. In front-end development, using sessionStorage is a common storage solution. However, since sessionStorage is browser-based storage, some security issues need to be paid attention to to ensure that the stored sensitive information is not maliciously accessed and used.

For students who are familiar with database operations, writing beautiful SQL statements and finding ways to find the data they need from the database is a routine operation. For students who are familiar with machine learning, it is also a routine operation to obtain data, preprocess the data, build a model, determine the training set and test set, and use the trained model to make a series of predictions about the future. So, can we combine the two technologies? We see that data is stored in the database, and predictions need to be based on past data. If we query future data through the existing data in the database, then it is
