Ok I have a database that includes two tables. A datatable that looks like:
and a metadata table that looks like:
I want to select columns from the datatable based on the variable column in the metadata table. Such that I end up with:
Thus I need to do something like:
SELECT [pivot variable.metadata] FROM datatable;
Anyone know how to do the pivot of the metadata.variable column in SQLite?
