我有一个左加入v_gate_pm_trip与v_fate_pm_trip_cntr一个事实表。 我能够通过之日起的一个月名(到达)来生成QVD DT)howerver,当它加载*从居民实际上,没有数据被读取的所有月份。
FACT:
LOAD "TRIP_ID",
"PM_M",
"ARRIVE_DT",
MonthName("ARRIVE_DT") as MONTH_NAME, //find out the monthname present in the data
SQL SELECT *
FROM EODWADMIN."V_GATE_PM_TRIP";
LEFT JOIN
LOAD "TRIP_ID",
"CREATE_DT",
"MODIFIED_DT";
SQL SELECT *
FROM EODWADMIN."V_GATE_PM_TRIP_CNTR";
// Start looping through each distinct value in the Month field
for i = 1 to FieldValueCount('MONTH_NAME')
// In-loop variable that will get the current increment value from the Month field
let sMonhValue = FieldValue('MONTH_NAME', $(i));
trace Storing data for MONTH_NAME --> $(sMonhValue);
// NoConcatenate is used to tell Qlik to not concatenate the same tables
NoConcatenate
// Load the data for the current iteration month from the main data table
TempTable:

Resident
FACT
where
MONTH_NAME = $(i) order by ARRIVE_DT;
// Store one month data in qvd. The name of the qvd will include the month value
Store TempTable into FACT_$(sMonhValue).qvd;
// If the qvd files need to be stored somewhere else - just provide the path like:
//Store TempTable into c:\users\UserName\Documents\RandData_$(sMonhValue).qvd;
// Drop the temp table. Otherwise it will get concatenated to the "previos" temp table
Drop Table TempTable;
next
// At the end the app will contain only one table - `RandData`
