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, the ACCESS database itself has many problems: performance is not good; data is not secure, users can directly use access to open data

First, Introduction:Although SQLite database is composed of a single file, but in fact there are some hidden temporary files in SQLite runtime, these temporary files for different purposes exist, for developers, they are transparent, so in the process of development we do not need to pay attention to their existence. However, if you can have a good understanding of the mechanism and application scenarios of

SQLite Introduction SQLite is a very popular embedded database. It supports the SQL language and has good performance only with a small amount of memory.

One, attach database: The ATTACH database statement adds another database file to the current connection, and if the file name is ": Memory:" We can treat it as a memory database and the memory databases cannot be persisted to disk files. If you are manipulating a table in a attached database, you need to add a database name, such as Dbname.table_name, to the table name. The last thing to note is that if a transaction contains multiple attached database operations, then the transaction is still

In the development of Win10 UWP, we can use SQLite. This article explains how to use SQLite in UWP. Because SQLite is Cross-platform, the version is numerous, I just started to use when do not know which to install, what WP8, WP8.1, Win RT ... I can't touch my head. I hope this article can make people take a little detour. One, add

SQLite is a lightweight local file database and is a relational database management system that complies with acid. Its design goal is embedded, and has been used in many embedded products, it's powerful, fast, it occupies a very low resource, in embedded devices, may only need hundreds of K of memory is enough. It can support the mainstream operating system such as Windows/linux/unix, and can be combined with many program languages. Data types of

The source of the data import can be output from other applications, or it can be a specified text file, where the specified text file is used.1. First, determine the imported data source, here is the text file to be imported, in a fixed format.2. Then, according to the imported file format, determine the target data table that you want to import, if not, you can create a corresponding data table according to the text file format to be imported.3. Finally, execute the. Import command to import t

SQLite Introduction In the introduction of System. data. SQLite is a single-host database management system similar to Access. It defines all databases (including definitions, tables, indexes, and data) are saved in a single file. In addition, SQLite is a class library implemented in C. It has good performance in terms of memory consumption, file size, and simpli

It is also a bit of programming memo. SQLite is a good embedded database. This embedded database is basically synonymous with exquisite and lightweight. SQLite references many scenarios, and Firefox and Android have internal applications, the code for this small database is not much, but its functions are quite complete. I will not describe how to use it here. If you want to know how to use it, please refer

SQLite is different from most other modern SQL databases in terms of basic design goals, and its goal is simple. SQLite follows this goal, even if this occasionally leads to inefficiency of some features. Here are some defects of SQLite: SQL-92 Characteristics As mentioned above, SQLite does not support some features a
