Hi,
First post with an issue that is probably very simple but is driving me mad. I have searched the forums (and Google) for the answer but i cannot find it. Odd really, as it is a fundamental part of any data of any data control. Nevertheless, i just cannot figure out how to append new data to an existing data. I either end up losing the data of overwriting the data (I suspect deleting the table and creating a new one).
What I have is a series of report delivered daily, with a time stamp in the report name. What I would like is to import the latest report into the table for further trend analysis.
This is what I have (that does not work)
Let DaysBack=1;
Let StartDate=date(Today())-DaysBack;
Let FolderYear = Year(StartDate);
Let FolderMonth = num(Month(StartDate),00);
Let FolderDay=num(Day(StartDate),00);
Let FolderName='PROJECT'&' '& FolderYear&'-'&FolderMonth&'-'&FolderDay;
Let DirectoryP1GSM='lib://Company_Local/'&FolderName&'/*GSM_PROJECT_P1.txt';
//create path name to file for import (previous day)
TempTable:
LOAD * FROM [$(DirectoryP1GSM)](txt, codepage is 28591, embedded labels, delimiter is '\t', msq,table is [GSM_P1]);
//import new data into temporary table
GSM_P1:
concatenate
LOAD * Resident TempTable;
//append temporary table to main table (GSM_P1)
Drop Table TempTable;
//lose temporary table and free up memory
What I end up with is a loss of all tables!!
Is should be noted the structure (headers etc) of each imported file is exactly the same.
HELP!!
Thanks,
Paul
