我在做类似的事情
...
OracleCommand oCommand = new OracleCommand();
oConnection.Open();
oCommand.Connection = oConnection;
oCommand.CommandText = "SELECT * FROM employees WHERE user = :User";
oCommand.Parameters.AddWithValue(":Name","Employee1");
DbDataReader dbRdr = oCommand.ExecuteReader();
那么这会抛出一个例外：
ORA-01745: invalid host/bind variable name
编辑：连接字符串如下所示：
"Data Source=orcl;Persist Security Info=True;User ID=user_id;Password=pwd;Unicode=True"
oConnection.Open();所以我假设我的连接字符串是正确的.
我在哪一方面犯错？
