This section describes the arguments used to build a connect string to a MySQL database. In order for a SourcePro DB application to interact with a database, an RWDBDatabase instance must be created by calling:
RWDBManager::database(accessLib, serverName, userName,
passWord, databaseName, connectOptions);
|
All arguments are of type RWCString. These parameters are passed to the MySQL C API function mysql_real_connect().
The arguments you must provide to RWDBManager::database() are:
accessLib: If your DB Access Module for MySQL is compiled as a DLL or shared library, provide the name of the DLL or shared library. See the document Building Your Applications for information about naming conventions. If you are using a static library, supply the string "MYSQL".
serverName: Supply the name or the IP address of the MySQL server to which you are connecting.
userName: Supply a valid MySQL login ID.
passWord: Supply the password for the user specified by userName.
databaseName: Supply a valid database name. The databaseName is required due to a restriction from mysql_real_connect().
connectOptions: If the port number is other than the default, pass a string with the syntax PORT=XXXX where XXXX is the port number to use to connect to the server. For example: PORT=3667
Here are two examples of opening a database.
The first example accesses a MySQL Server database using a shared build of the Access Module. A user name and password are provided. Notice that accessLib is defined as "mys8015d.dll", indicating that the application will dynamically load the Access Module at runtime:
RWDBDatabase aDB = RWDBManager::database ("mys8015d.dll",
"MySQL-Server", "cratchitt","scrooge", "");
|
The second example accesses MySQL Server using a static build of the Access Module. Notice that accessLib is defined as "MYSQL", indicating that the application will use the static version of the Access Module:
RWDBDatabase aDB = RWDBManager::database ("MYSQL",
"192.168.1.100","cratchitt","scrooge", "");
