Changing the default schema in Oracle

The application I was working on assumed that the user would always be in the default schema. I ran into a snag when I had to connect to the staging environment where the read only user that I was provided with didn’t have all the objects in his schema.

The solution was to make a call to change the default schema using the ALTER SESSION call with this code.

        /// <summary>

        /// Sets the schema to use if one is configured.

        /// </summary>

        public static void SetSchema()

        {

            var schema = ConfigurationManager.AppSettings["SchemaName"];

            if (string.IsNullOrEmpty(schema)) return;

            using (var connection = GetConnection())

            {

                using (var command = new OracleCommand("alter session set current_schema=" + schema))

                {

                    connection.Open();

                    command.Connection = connection;

                    command.ExecuteNonQuery();

                }

            }

        }
