This asynchronous function replaces values and qualities in the history database at the specified timestamps for one or more items. If no value exists at the specified timestamp, the new value shall not be inserted; instead errors shall indicate an error. This function is intended to replace existing values at the specified timestamp; e.g., correct lab data that was improperly processed, but inserted into the history database.
The results are returned via the client's UpdateComplete event handler.
Overload List
| Overload | Description |
|---|---|
| Replace(Int32,Int32[],DateTime[],Object[],Int32[],Int32[],Int32) | This asynchronous function replaces values and qualities in the history database at the specified timestamps for one or more items. If no value exists at the specified timestamp, the new value shall not be inserted; instead errors shall indicate an error. This function is intended to replace existing values at the specified timestamp; e.g., correct lab data that was improperly processed, but inserted into the history database. The results are returned via the client's UpdateComplete event handler. |
| Replace(Int32,Int32[],Int64[],Object[],Int32[],Int32[],Int32) | This asynchronous function replaces values and qualities in the history database at the specified timestamps for one or more items. If no value exists at the specified timestamp, the new value shall not be inserted; instead errors shall indicate an error. This function is intended to replace existing values at the specified timestamp; e.g., correct lab data that was improperly processed, but inserted into the history database. The results are returned via the client's UpdateComplete event handler. |
| Replace(Int32[],Int64[],Object[],Int32[],Int32[]) | This synchronous function replaces the values and qualities in the history database at the specified timestamps for one or more items. If no value exists at the specified timestamp, the new value shall not be inserted; instead errors shall indicate an error. This function is intended to replace existing values at the specified timestamp; e.g., correct lab data that was improperly processed, but inserted into the history database. |
