Right, I missed that.

My last 2 cents on the whole topic. There is a fundamental design issue
here with deciding to handle the expression /column <
(value/literal/parameter typed or not)/ by converting the column to a
string. Obviously, with INSERT INTO the data values must be coerced to
the destination column type. In this case, while there is a
parsing/optimizing decision to be made, it should be made with a strong
bias to convert to the column type (and then handling any tricky
coercion failures or optimization issues).

Again thanks for your help,
Matt
