+# Connection Properties on Apache Arrow Flight SQL ODBC Driver
+
+## Setting ODBC Connection Properties
+
+ODBC connection parameters can be set in a connection string or defined in a DSN inside your system's odbc.ini.
+
+The following sample connection string and sample DSN are two equivalent ways to connect to Arrow.
+
+### Sample Connection String
+```
+"driver={Apache Arrow Flight SQL ODBC Driver};HOST=1234.56.789;port=12345;uid=sample_user;pwd=sample_password;useEncryption=false;UseWideChar=true;"
+```
+
+### Sample DSN
+```
+[Apache Arrow Flight SQL]
+Driver        = Apache Arrow Flight SQL ODBC Driver
+Host          = 1234.56.789
+Port          = 12345
+UID           = sample_user
+PWD           = sample_password
+useEncryption = false
+UseWideChar   = true
+```
