Issue with map creation using country geo polygonal data

[satyaban]

Dear All,

I want to draw area map in my visualisation where I am using country Geo QVD file and works fine . But due to some organisation policy level issue I cannot use qvd file in qlik sense .

__countryAliasesBase:
LOAD
    Alias AS [__Country],
    ISO3Code AS [__ISO3Code]
FROM [lib://AttachedFiles/countryAliases.qvd]
(qvd);

__countryGeoBase:
LOAD
    ISO3Code AS [__ISO3Code],
    ISO2Code AS [__ISO2Code],
    Polygon AS [__Polygon]
FROM [lib://AttachedFiles/countryGeo.qvd]
(qvd);

Basically I had tried to store country details and its polygonal values in Oracle DB again there is some issues like "STRING LATERAL IS TOO LONG"  because of high range of polygonal values .

Reference Country Geo data : https://github.com/datasets/geo-countries

So is there any ways to store same polygonal values or any other way to draw area layer in qlik sense map .

Thanks in advance
