I. Introduction
Databases are one of the most popular applications. Almost every business department uses databases to record and manage various types of data. In VC, we can select database support when creating a project, select the data source and related tables, and select crecordview as the base class of our program, in this way, you can establish associations between applications and databases without having to compile any Code. However, the premise is that you know which database to use w

In VC, there are two ways to connect to a database by using ODBC. The first method is to use odbc api, and the second is to use mfc odbc. Here I will only talk about MFC

ODBC(Open database Connectivity, opening databases interconnect)In 1992, Microsoft's Open Services Architecture (Wosa,windows Open service Architecture), a component of the database, established a set of specifications and provided a set of standard APIs (application programming interfaces) for database access. These APIs use SQL to accomplish most of their tasks. ODBC itself also provides support for the S

Ole db (Oledb)It is Microsoft's strategic low-level application interface to different data sources. Ole db not only supports the Structured Query Language (SQL) of Open Database Connectivity (ODBC), but also supports other non-SQL data types.
As a design of Microsoft's Component Object Model (COM), ole db is a set of methods for reading and writing data (which may have been called a channel in the past ). Objects in old dB mainly include data source

This is provided in the sqlitedll.zip file, including sqlite3.def.AndSqlite3.dll file, of course, you can directly use WIN32API such as loadlibrary to operate the DLL, find the functions contained in it, and use these functions, but generallyThe reason for not doing this is very simple: This is too troublesome. Therefore, we usually use the Lib command to generate the Lib for link, and then include the SQLite
SQLite has no restrictions on the Authorization protocol and supports most of the standard SQL 92 statements. We believe more and more people will use this database.
The combination of PHP and SQLite is just like the combination of ASP and ACCESS in the past. ACCESS can be maliciously downloaded, and SQLite cannot be spared because

I. Memory Database:
In SQLite, databases are usually stored in disk files. However, in some cases, we can keep the database in the memory. The most common method is to pass ": memory:" To the database file name parameter when calling sqlite3_open (), for example:Copy codeThe Code is as
