| ===== Description ===== | ===== Description ===== | ||
| - | The USER, CURRENT_USER and SESSION_USER functions return the current user of Omnidex. Omnidex does not provide a user security layer, and so these functions always return a value of "DEFAULT". | + | The CURRENT_TIME function returns the current time from the server's time-of-day clock. The function is processed once at the beginning of the execution of the SQL statement. A new value is not obtained with each reference or with each fetched row. In a client-server or Omnidex Grid application, the time returned is from the individual server processing the query. |
