Ways of Opening Oracle Databases

1. Opening through ODBC DSN (interface: ADO or BDE). Select 'ODBC data source' option and then select the ODBC DSN from the dropdown list. But first, you should create an ODBC DSN of the corresponding type using Windows administrative tools, and point it to the database.

2. Opening through BDE alias (interface: BDE). First, you should create the alias of type ORACLE using BDE Administrator tool or Tools | BDE | Aliases menu of Reportizer, and point it to the database.

3. Opening through connection string (interface: ADO). Select 'Connection string' option and write a connection string. This way is the most flexible one because it allows to specify many additional parameters in the connection string and override standard Reportizer connection behaviour. But it is recommended basically for advanced users. Here are basic connection strings (more examples and details can be found in the Internet):

Provider=msdaora;Data Source=MyOracleDB;User Id=myUsername;Password=myPassword;   (Microsoft OLE DB Provider for Oracle must be installed)

Provider=OraOLEDB.Oracle;Data Source=MyOracleDB;User Id=myUsername;Password=myPassword;   (Oracle Provider for OLE DB must be installed)

Driver={Microsoft ODBC Driver for Oracle};ConnectString=OracleServer.world;Uid=myUsername;Pwd=myPassword;   (Microsoft ODBC Driver for Oracle must be installed)

Provider=MSDASQL.1;Extended Properties="DSN=ORACLE_DB;UID=MyUsername;PWD=MyPassword"

Oracle client must be installed.
