Object-oriented approach Mysqli class The way of 3.PDO Example Use the Mysqli class to access the database: 1. The object in Mysqli, which is equivalent to establishing a channel between PHP and MySQL database $db = new Mysqli ("localhost", "root", "123",

In the actual development process, the operation of the database is nothing more than "additions and deletions to check." In terms of the most common single-table operations, statements are similar except for tables and fields, and developers need to write a number of similar and tedious statements to complete business logic. To solve these tedious data manipulation statements, we first thought of using an ORM framework, such as Hibernate. By integrat

There are many methods to convert an Access data table to a mysql DATA table and search for it online. However, my method seems extremely simple. Export an excel file in access and import it to mysql. Mysql's visual operation tool is really simple! Specific practice: www.2cto.com 1. In the

Sometimes we want to obtain part of the data in the SQL database, while the other part of the data in the access database, but sometimes we need to associate the data in the two databases for query, integrating them into a dataset is undoubtedly a good method. follow the steps below to

Step 5: complete the data access layer Note that the ProductsTableAdapters class returns the values of CategoryID and SupplierID from the Products table, but does not include the CategoryName field of the Categories table and the CompanyName field of the Suppliers table, although when we display product information, these are probably the fields we want to display. We can expand the start method GetProduc

The actionform in struts is a Vo; The Entity Bean in Hibernate is a po, also called pojo; The criteria in Hibernate is equivalent to a Qo; When using hibernate, we will define some query methods. These methods can be written in interfaces and have different implementation classes. This interface can be said to be a Dao. I personally think that Qo is similar to DTO. Po is also called Bo. The closest layer to the database is the o in the orm. It is basically an attribute corresponding to t

Step 3: add parameterization method to the data access layer So far, ProductsTableAdapter has only one method, GetProducts (), which returns all products in the database. Operations on all products are useful, but we often want to obtain information about a specific product or all products under a specific category. To add such a feature to our data

More than a year ago bought @mrexcel's "Let Excel Fly" this book. The overall idea is to use Access combined with Excel to significantly improve data analysis efficiency.Recently I took it out and looked at it. The 15th chapter, more "Advanced" than the advanced screening, P241. Mainly about multi-table association query, can be applied to one-to-many scenarios.P248: Three types of join properties.Union uni
