set up oracle odbc connection

When using C + + to access Oracle, ODBC is an option and the DSN needs to be configured when CDatabase is used for OpenEx. Here's how to configure DSN Open ODBC Data Source Manager (ORC1 I have configured, not before configuration) Click "Add" and a dialog box appears:Select Oracle in Oraclinetxxx, after

replaced by this format. 4. Add the TNS_ADMIN environment variable to point to the created tnsnames. ora configuration file. So far, the configuration has been completed. You can use tools such as pl/SQL developer to connect to a remote oracle database. The database is the name of the added tns Service (WSR here) If you want to use odbc to connect to the database, you also need to add

There are 3 Oracle connection queries: cross-Connect, inner-join, outer-join. The result of a cross join is a superset of the results of other connections, and the outer join result is a superset of the result of the inner join. Take the example of Departments_v, Employees_v two View data (4 Department data, 9 personnel data) 1. Cross-linking: also known as the Cartesian product
