The function ObjectInfo() can return different data types depending on the
parameters used and this has always caused problems when querying. One
solution is to create a temporary column and do an update with the
ObjectInfo() value which does work. Then, reissue your query using the
results in the temporary column. I have tried other methods (casting, etc.)
but nothing seems to work, or work well. If anyone has cracked the direct
method, do let me know!
