for an extension we try to determine if a column has text or numeric values or both to determine if we need to select string or number values.
We tried to use the qTags field but ran into some odd behaviour. The documentation does not give a lot of information what this field actually is and how its computed.
LOAD * Inline [
A, B, C
38788010, I2040407, ABC
will create 3 columns with A having $numeric and $integer qTags, B having no qTags and C having $ascii and $text qTags.
I would have expected that B has all 4 options.
Does anyone have any pointers where qTags is explained?
