Hello Django
what version and flavor of hana do you use?
I tried a retrieval with NCLOB via oData it works...I am on SPS7 and use the on premise version of HANA but i have not tested with really large data values
Suggestion: Why don't you create a view with a calculated column Substr(NCLOBField,0,5000) instead of the NCLOB...
Or
You could switch to an XSJS service instead of oData but you will need to write a little more code
Also you need not create a new view to eliminate you NCLOB data there is an option to use 'With' in the oData service look at
Thomas Jung gives a code sample on how to do this.
Warm regards
