GETCOLTIME action
Function
The action retrieves the values' times in given column of structured local variable (i.e. local variable of the Record type).
Declaration
| Blok kódu | ||||
|---|---|---|---|---|
| ||||
GETCOLTIME _srcRec^Col, _dstRec^DateTimeCol |
Parameters
| _srcRec | in | Row identifier of local variable of the Record type - source column used to acquire times of individual values. |
| _dstRec | out | Row identifier of local variable of the Record type - target column used to write the times in. |
Description
For each item in the column DateTimeCol of the structure _dstRec, the action sets a value of the Absolute time type, which represents a time of the value occurrence in corresponding row and given column of the structure _srcRec. There must be the same number of rows in both the structures.
The action represents a substitution of the following loop:
| Blok kódu | ||||
|---|---|---|---|---|
| ||||
RECORD (SD.Def) _srcRec
RECORD (SD.Def) _dstRec
BEGIN
REDIM _srcRec[10]
REDIM _dstRec[10]
; Execution of the action GETCOLTIME
IF _srcRec\DIM # _dstRec\DIM THEN
; The error_ERR_RANGE_ERROR
END
ENDIF
INT _row
_row := 1
DO_LOOP
EXIT_LOOP _row > _srcRec\DIM
_dstRec[_row]^DateTimeCol := _srcRec[_row]^Col\TIM
_row := _row + 1
END_LOOP
; Action end
END |
The column DateTimeCol used in the example must be of the Absolute time type.
Example
The following example executes the loop described above using the the GETCOLTIME action GETCOLTIME .
