each file of the table you want to steal, and then write the contents of the table to your own database file: Now you have a new table y that contains other_db.x content that you can access completely. To prevent someone from attacking you in the same way, you should set permissions on the data directory according to the guidelines for internal security: Secure Data Directory

providing a way to save XML files to support XML, SQL Server provides an interface to relational data that allows you to read and write XML data in tables and other database objects. The XML features inherent in SQL Server include: You can access SQL Server through HTTP, template queries, FOR XML clauses, and OPENXML () functions. Next, I'll tell you how these functions work and how they can benefit your b

database, if you know where errors may occur and how to handle the errors, the possibility of errors caused during the Database Upgrade will be greatly reduced. The best advice I can provide for Database Upgrade is to make the most complete plan before development. Now, I will list the problems that may occur during

are some of the factors that affect: The index does not include one or several columns to be sorted; The order of the columns in the group BY or ORDER BY clause is not the same as the index; The sorted columns come from different tables. In order to avoid unnecessary sorting, it is necessary to build the index correctly and consolidate the database table reasonably (although it may sometimes affect the normalization of the table, but it is worthwhile

Use EF DataBase first to make a simple MVC3 registration site ORM (Object Relational Mapping) is a data access technology in object-oriented languages, and in ASP. NET, you can simplify data access by using the ADO. NET Entity Framework technology. In EF, there are three ways to do this, code First,model and

1. AccessWhen we do small projects, especially small MIS systems, we usually use databases to store data. It has been observed that most small systems use access databases. Some systems have changed the data file suffix to cover up the database type. In fact, as long as the data is changed back to MDB and opened with access, the data is clear at a glance, in fact

Use Access Database in C ++ Access database has been widely used in management. In the long-term use, many data files are stored in Access database files. When C ++ builder is used for programming, it is often necessary to use an

the best way to separate database application development from the physical implementation of database design. Stored procedures can be created in one place and invoked by the application.If the database on which the stored procedure is based changes and the stored procedures are carefully modified to reflect these changes, the call to the stored procedure will

the query owner can save the modified query. Only the query owner can change the query ownership. You can also set the default permissions for all new queries. Click "options" on the "Tools" menu, click the "Table/query" tab, and then click the "execution permission" option you want to use. Q: How to define user-level security?

understand how to use it, there are many examples to illustrate this problem. It is not difficult to encapsulate ASP's database operations, and I believe you have done similar code or borrowed other people's encapsulated code before. However, as you know, the use of encapsulated code once the error, row error is a more troublesome thing, generally speaking, the simpler the encapsulation operation is more complex. When I write this code, I have done
