我该下载的也下载了，该设置的也设置了
最后出现了：Warning: odbc_connect() [function.odbc-connect]: SQL error: [Microsoft][ODBC 驱动程序管理器] 未发现数据源名称并且未指定默认驱动程序, SQL state IM002 in SQLConnect求大神们帮忙解决

odbc_connect
(PHP 4, PHP 5)odbc_connect — Connect to a datasource说明
resource odbc_connect ( string $dsn , string $user , string $password [, int $cursor_type ] )
The connection id returned by this functions is needed by other ODBC functions. You can have multiple connections open at once as long as they either use different db or different credentials.With some ODBC drivers, executing a complex stored procedure may fail with an error similar to: "Cannot open a cursor on a stored procedure that has anything other than a single select statement in it". Using SQL_CUR_USE_ODBC may avoid that error. Also, some drivers don't support the optional row_number parameter in odbc_fetch_row(). SQL_CUR_USE_ODBC might help in that case, too.参数
dsn
The database source name for the connection. Alternatively, a DSN-less connection string can be used.user
The username.password
The password.cursor_type
This sets the type of cursor to be used for this connection. This parameter is not normally needed, but can be useful for working around problems with some ODBC drivers.The following constants are defined for cursortype:
SQL_CUR_USE_IF_NEEDED
SQL_CUR_USE_ODBC
SQL_CUR_USE_DRIVER
返回值
Returns an ODBC connection id or 0 (FALSE) on error.
// Microsoft SQL Server using the SQL Native Client 10.0 ODBC Driver - allows connection to SQL 7, 2000, 2005 and 2008
$connection = odbc_connect("Driver={SQL Server Native Client 10.0};Server=$server;Database=$database;", $user, $password);// Microsoft Access
$connection = odbc_connect("Driver={Microsoft Access Driver (*.mdb)};Dbq=$mdbFilename", $user, $password);// Microsoft Excel
$excelFile = realpath('C:/ExcelData.xls');
$excelDir = dirname($excelFile);
$connection = odbc_connect("Driver={Microsoft Excel Driver (*.xls)};DriverId=790;Dbq=$excelFile;DefaultDir=$excelDir" , '', '');
