How to convert this sql query to DAX

Try this -

Measure = 
CALCULATE(
    SUM('KPI A'[value]),
    FILTER(
        'KPI A',
        'KPI A'[period] IN 
        SELECTCOLUMNS(
            FILTER(
                CROSSJOIN('Time', 'period'),
                'Time'[period] = 'period'[Period] &&
                'Time'[quarter] >= 'period'[quarter] - 1 &&
                'Time'[quarter] <= 'period'[quarter] - 5
            ),
            "period", 'Time'[period]
        )
    )
)

DAX measure:

Selected Value = 
VAR CurrentQuarter = MAX('Period'[Quarter])
VAR FilteredPeriods = 
FILTER(
ALL('Time'),
'Time'[Quarter] >= CurrentQuarter - 5 &&
'Time'[Quarter] <= CurrentQuarter - 1
)
RETURN
CALCULATE(
MAX('KPI A'[Value]),
'KPI A'[Period] IN DISTINCT(SELECTCOLUMNS(FilteredPeriods, "Period", 'Time'[Period]))
)
