Oracle managed data access connection string example

Create a OracleCommand object to work with Oracle Database : OracleConnection conn = DBUtils.GetDBConnection (); // Way 1: // Create a Command from Connection. OracleCommand cmd = conn.CreateCommand (); // Set Command Text cmd.CommandText = sql; // Way 2: // Create new Command OracleCommand cmd = new OracleCommand (sql); // Set connection. In order to successfully connect to the secondary using Application Intent, your connection string must: 1 Specify the availability group listener name. 2 Specify the catalog - the database that is defined in the availability group. 3 Specify the 'application intent' (SQLClient or SQL OLE DB) or 'applicationintent' (ODBC) connection property. To access the property, click the File menu, point to Options and settings, and then click Options. In the Options dialog box, go to the Security category, clear the property's checkbox if selected, and click OK.

Open a file (File -> New File) and set the file type to SQL (View -> Command Palette -> PostgreSQL: Manage Connection Profiles, and opt to select SQL as your file type, then select SQL from the list). Your file should now have the red barrel SQL icon on the tab. Now create a Connection Profile. Follow the View -> Command Palette -> PostgreSQL. Set the driver to the name of your driver. driver = ' {ODBC Driver 13 for SQL Server}'. Next, we’re going to set up the connection string. There are 2 ways to define the connection string, one is using quote_plus under urllib package to parse the string, the other is using sqlalchemy’s URL format. # Using urllib. Anybody who has worked with Oracle is aware of how this works. For .NET applications we are used to putting connection strings into configuration files and being done. That doesn't work with the unmanaged driver. The connection string you use is a pointer to the .ora file. A final issue with the driver was fixed in newer versions (v11+).
