in the system information. If no DSN exists. in addition, we can specify whether this function needs to display a dialog box to provide more information for users. for example, if the user misses the database name, he will instruct the ODBC driver to display a dialog box for the user to select the database to connect. sqlbrowseconnectlevel 1: This function allows you to enumerate data sources at runtime. it is more flexible than sqldriverconnect. Bec

function if you already have a DSN for the database you need to use. Sqldriverconnectcore This function provides a more sqlconnect choice. We can connect to a data source that is not defined within the system information. If there is no DSN. In addition, we can specify whether the function needs to display a dialog box to provide more information to the user. For example, if the user omits the name of the database, it instructs the ODBC driver to display a dialog box that allows the user to sel

characters, this greatly simplifies the use of sqlbrowseconnect functions. 2. Establish a connection with the data source If you use odbc api functions for connection, both sqlconnect, sqldriverconnect, and sqlbrowseconnect functions can be implemented. The sqlconnect function is used to directly establish a connection with the data source given all parameters. sqldriverconnect is used to specify some

This article uses the SQL2005 + VS2008 environment to successfully connect to the database in ODBC API mode.1.SQL Installation and Environment configurationThis part of the Web-based random search has a lot of information, and it is easy to configure the success.Note the key points: sa account configuration, remote connection configuration.After the configuration succeeds, you can successfully connect to the remote database as shown in:　　2. Build the console program, using the ODBC API, the lang

you use the SQL Server Native Client OLE DB access interface ADO and ADO. NET, this interface is used. The connection string can be like this: 1 string connstr = "Server=(local);Database=AdventureWorks;User ID=sa;Password=test;MarsConn=true"; If you use the SQL Server Native Client ODBC driver The connection string can be like this: 1 SQLSetConnectAttr(hdbc, SQL_COPT_SS_MARS_ENABLED, SQL_MARS_ENABLED_YES, SQL_IS_UINTEGER);2 SQLDriverConnect(hdbc

, hdbc); Description: A connection handle corresponds to a data source and can have multiple connection handles. 3. Connect to the data source and connect to the data source sqldriverconnect (hdbc,...) using the connection handle. Description: obtain registration information in the dialog box and connect to the data source. 4.

applications, you can also set the special property of the provider: ssprop_init_currentlanguage before connecting.(2) Open Database Connection (ODBC) applications can include the language keyword in the connection string specified on sqldriverconnect. ODBC applications can also specify language settings in the SQL Server ODBC Data Source definition.(3) The db-library application can use dblogin to allocate loginrec, and then use the dbsetnatlang mac

data source. A connection handle that accesses a data source contains all the connection information that includes status, transaction declarations, and error information.(3) SQLDriverConnect: Similar to SQLConnect, used to connect to a driver or data source. But it has more connection information than SQLConnect support data source;(4) SQLBrowseConnect: Supports an interactive method to retrieve or list the attributes and property values required to
