ODBC is an underlying access technology. Therefore, ODBC APIs can be customer applications. Program You can set and control databases at the underlying layer to implement functions that cannot be completed by advanced database technology. However, ODBC can only be used for relational databases, it makes it difficult to access the object database and other non-rel
When programming, we need to save various types of data received in real time and replay the data in the future. We should create a data file, which can be read and written by common files, however, when there are many data types and data playback is required at any time, a large dynamic array is required during programming. This will occupy a large amount of system resources and even cause program crashes; the database can better solve this problem. We put the data into the data source file and

Using ODBC Connection pooling with cdatabase (under MFC)
Rating:None
James R. twine()August 3, 1999.
Environment:Visual c ++ 6
This article shows how you can use ODBC Connection pooling with MFC's cdatabase and crecordset objects. it will explain the way in which I did it, which I am sure is not the only way it can be done. also, I am no database expert,
How to configure a 32-bit ODBC data source in 64-bit WindowsThe procedure is as follows:1. Install mysql ODBC driver: mysql-connector-odbc-5.3.4-win322. Open cmd and enter C: \ Windows \ SysWOW64 \ odbcad32.exe (full path input is required !)Then, we need to configure mysql ODBC in the open
Recently, I tried to use sqlserver2005 integrate services to extract data from heterogeneous databases and use the ODBC-connected teradata as the data source. Refer to the "SQL Server 2005 database development details" (Electronic Industry Press Hu baijing Yao Qiao Mei) P361-363, the operation steps in SSIs are as follows:
(1) Right-click the Connection Manager and choose create connection> ODBC to create
The ODBC class of MFC encapsulates complicated ODBC APIs and provides simplified calling interfaces, which greatly facilitates database applications.ProgramDevelopment. Programmers can perform most database operations without having to know the detailed odbc api and SQL.
The ODBC categories of MFC mainly include:

ODBC File DSN's little secret
1. Use the attached WordPad text editor to create a suffix named. The file for the DSN, formatted as follows, and then saved in text format:
Note: The format is important and must be saved as ' text format ', otherwise the editor should be OK.

The data in the Oracle database is loaded to the DropDownList for the first time,
In addition, you can select a user name in the DropDownList to obtain all information about the user,
The function is very simple (because it is mainly used to access the Oracle database)
Let's look at Code-Behind.
The above is the Code-Behind part. In fact, apart from some different calling methods,
Basically, you can use ADO. NET to access SQL Server,
Then we can see the effect,

Using the JDBC-ODBC bridge to connect to the Oracle database and JDBC driver is almost the same, so we don't have to set the environment variable. There are two key statements for connecting to the database in JDBC:
Class. forname ("oracle. JDBC. Driver. oracledriver ");Connection con = drivermanager. getconnection ("JDBC: oracle: thin: @ 127.0.0.1: 1521: dbname", "username", "password ");
Similarly, bridge connections are the two statements, but
that the QueryString parameter does not contain the page parameter. The first page of data is displayed.
IntPage=1;
} Else {

IntPage=Java. Lang. Integer. parseInt (strPage );
If (intPage1)IntPage=1;}
// Load the JDBC-ODBC driver
Class. forName ("sun. jdbc. odbc. JdbcOdbcDriver ");
// Set the database connection string
