Hi Team,
I am trying to create a qvd monitor application, and have taken the reference from GIT hub library.
I am using this piece of code as suggested by @Qlik-Peterman
QvdTableHeader:
LOAD FilePath(FileName()) as Name, *;
LOAD QvBuildNo,
CreateUtcTime,
SourceFileSize,
FileName() as QVDFileName,
'$(FolderName)' as QVDFolder,
TableName,
RecordByteSize,
NoOfRecords,
Offset,
Length
FROM '$(File)'(XmlSimple, Table is [QvdTableHeader]);
//=========== qvd source of meta ---xml header ========
LOAD FilePath(FileName()) as Name, *;
QvdFieldHeader:
LOAD FieldName,
BitOffset,
BitWidth,
Bias,
NoOfSymbols,
Offset as HeaderOffset,
Length as HeaderLength,
[NumberFormat/Type] as Type,
[NumberFormat/nDec] as nDec,
[NumberFormat/UseThou] as UseThou,
[NumberFormat/Fmt] as Fmt,
[NumberFormat/Dec] as Dec
FROM '$(File)'(XmlSimple, Table is [QvdTableHeader/Fields/QvdFieldHeader]);
// ------------------------------------
// Get the number of columns manually
// ------------------------------------
LOAD
Name,
count(distinct FieldName ) as NoColumns
resident QvdFieldHeader
group by Name;
Next File
End sub
// ---------------------------------------------------------
// Now call the control loop above with the folder variable
// ---------------------------------------------------------
FOR i = 0 to NoOfRows('QVDFolders')-1
LET FolderName = peek('QVDPath', i, 'QVDFolders');
Call DoDir('$(FolderName)')
NEXT
let main_end=now();
QVDMetaHeader:
LOAD
Name & '_' & '$(MetaTime)' as %QVDKey,
Name as QVDName,
Date('$(MetaTime)', 'YYYY-MM-DD hh:mm:ss') as QVDMetaTime,
QVDFileName as QVDFileName,
QVDFolder as QVDFolder,
TableName as QVDTableName,
NoOfRecords as QVDNumRecs,
RecordByteSize as QVDRecLen
Resident QvdTableHeader;
IF Exists(QvdFieldHeader-1) THEN
Set vTable = '[QvdFieldHeader-1]';
ELSE
Set vTable = '[QvdFieldHeader-4]';
END IF
outer join
LOAD DISTINCT
Name as QVDName ,
NoColumns as QVDNumCols
// Resident [QvdFieldHeader-4];
Resident $(vTable);
However this last resident load is giving me an error, [QvdFieldHeader-4] table is not found.
Can someone please suggest where it's going wrong?
Regards
