CALCONDEMANDSTAT archIdent, timeFromIdent_TmA, timeToIdent_TmA, bCalcDepend[, statusIdent_Int] |
Parameters
archIdent | in | Reference to one value of historical value, column or row of structured historical value (see Note). |
timeFromItemIdent_TmA | in | Identifier of AbsTime type - interval beginning. |
timeToItemIdent_TmA | in | Identifier of AbsTime type - interval end. |
bCalcDepend | in | Identifier of Bool type - recalculation of dependent OnDemand archives. |
statusIdent_Int | out | Calculation (action) success. |
Description
The action sends requests to the process D2000 Archiv process to recalculate the statistical values of:
- one historical value (archIdent) - the value of the parameter bCalcDepend = @FALSE. The process Archiv Archiv process will calculate only defined historical value (archIdent),
- one historical value (archIdent) and all the historical values depending on it (in dependence on a value of the parameter bCalcDepend) - the value of the parameter bCalcDepend = @TRUE. The The D2000 Archiv process D2000 Archiv will calculate the given object (archIdent) and all archive objects that directly or indirectly depend on given archive object.
All the calculations are being executed for the time interval given by the parameters timeFromIdent_TmA and timeToIdent_TmA.
If the optional parameter statusIdent_Int is entered, the action will be terminated after terminating all required calculations on the Archiv process Archiv.
The parameter statusIdent_Int can get one of the following values:
- _ERR_TRANS_ABORT
- _ERR_TRANS_ERROR
- _ERR_TRANS_IGNORED
- _ERR_NO_ERROR
Note
The The archIdent parameter archIdent can also contain the reference to a part (row or column) or entire structured historical value.
Example:
Example:
- H.ColArchiv - reference to entire structured historical value
- H.ColArchiv[2] - reference to all values of structured historical value within the row of 2
- H.ColArchiv^ColName - reference to all values of structured historical value within the ColName column
