Incrementaal load not success

Wed, 25 Nov 2020 16:16:04 GMT

Hi,

Implemented the incremental load. Data is not fetching the updated records in report.

Fact Table:

LET vSQLSection = '
SELECT
BAL.CODE_COMBINATION_ID,
LED.LEDGER_ID,
LED.NAME LEDGER_NAME,
BAL.Last_Update_Date,
(CASE WHEN led.ledger_category_code = ' & chr(39) & 'PRIMARY' & chr(39) & ' then ' & chr(39) & 'Primary' & chr(39) & ' else ' & chr(39) & 'Reporting' & chr(39) & ' end) Ledger_type,
PERIOD_NAME,
NVL (bal.begin_balance_dr, 0) - NVL (bal.begin_balance_cr, 0) Begin_USD,
(nvl(bal.period_net_dr,0) - nvl(bal.period_net_cr,0)) NET_USD,

LET vUniqueKey = 'LEDGER_ID & CODE_COMBINATION_ID & PERIOD_NAME';

SET vLastUpdateFieldName = 'BAL.Last_Update_Date';

Call IncrementalLoad ('$(vTableName)', '$(vSQLSection)', '$(vUniqueKey)','$(vOutputTableName)','$(vLastUpdateFieldName)') ;

Below is the logic implemented

sub IncrementalLoad (vTableName, vSQLSection, vUniqueKey, vOutputTableName, vLastUpdateField)

Trace('$(vDataFolder)$(vOutputTableName).qvd');

Let v_Incremental_qvd = isNull(QvdCreateTime('$(vDataFolder)$(vOutputTableName).qvd'));

If (v_Incremental_qvd = -1) then

Trace(Beginning Full Load for $(vTableName));

LET v_SQL = '$(vSQLSection)';

$(vTableName):

Load

$(vUniqueKey) as key_Unique;

SQL $(v_SQL);

RENAME field LAST_UPDATE_DATE to Last_Update_Date;

ELSE

Trace(Beginning Incremental Load for $(vTableName) on $(vSite));

// get dates

Dates:

Load distinct Last_Update_Date

from $(vDataFolder)$(vOutputTableName).qvd (QVD);

//exit script;

GetMaxDate:

Load Max(Last_Update_Date) as MaxRecordDate

Resident Dates;

LET v_MaxRecordDate = date(Peek('MaxRecordDate', 0, 'GetMaxDate'));

Drop Tables GetMaxDate, Dates;

LET v_SQL = '$(vSQLSection) AND $(vLastUpdateField) >= '& chr(39) & v_MaxRecordDate & chr(39);

Trace($(v_SQL));

temp:

Drop Table temp;

ENDIF

Store $(vTableName) into $(vDataFolder)$(vOutputTableName).qvd;

Drop Table $(vTableName);

end sub

After reload we observed in where class last_update_date checking ' ' instead of latest date

Could you please give an idea how to fix the incremental load.
