Hi Thomas,
Don’t know what you mean by " pbs on datas” ???
I assume this spurious chars at the beginning of the strings ?
yes (triple count is ok in V7/V7, no RDF data loss)
Are you saying this string values where XMLLiteral in vs but are now
XMLSchema#string in v7 , which may be the cause ?
yes XMLLiteral in V6 (via DATATYPE function call) and XMLSchema#string in V7
Did you convert the RDF_QUAD table to column store mode also ?
yes
As would be interesting to know if this occurred when it was in v7 row
store original mode also …
i will check this and provide information
Have you tried dumping and reloading the RDF Quad data as also
suggested as an alternative previously ? ie
not at the moment but i will do as "plan B" if we have the same missing
types in V7 row store test
Best Regards
Hugh Williams
