    1. COYou do not explain here why number < text = true for variant types. In case 2 you define types as string and integer and the error is expected, but why if we remove types in Dim (make all of them variant) we will get true for both comparisons in case 2?

    2. COI couldn't find any plausible documentation for this in VBA, however it totally imitates the behavior shown in older versions of python (check http://stackoverflow.com/questions/3270680/how-does-python-compare-string-and-int). I am not sure whether the same reasoning could be applied here too for string to integer comparison.

    3. COOMG, Python 2 is also counter intuitive! Thanks for the link! Wondering what was in minds of the people who did this, why not just an error!!?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
