Ways of Opening Oracle Databases

 

1. Opening through FireDAC interface. Select FireDAC interface, click Oracle, then fill all needed database parameters.

2. Opening through ODBC DSN. Select ADO or BDE interface, then choose ODBC data source option and then select the needed ODBC DSN from the drop-down list. But first, you should create an ODBC DSN of the corresponding type using Windows administrative tools, and point it to the database.

3. Opening through BDE alias. Select BDE interface, then choose Alias option and then select the needed alias from the drop-down list. But first, you should create the alias of type ORACLE using BDE Administrator tool or Tools | BDE | Aliases menu of Database Tour, and point it to the database.

4. Opening through connection string. Select ADO interface, then choose Connection string option and write a connection string. This way is very flexible and allows to specify many additional parameters in the connection string and override standard Database Tour connection behavior. It is recommended 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"

Notes
Oracle client must be installed. The bit-version of it (32 or 64) must match the bit-version of the program.
