FYI, I found (and submitted an support ticket) for this soon after upgrading to 10.6.
for those of you that use the ‘edit’ command in an editor tab, beware that only one line is getting executed when you hit ctrl-enter, click the execute snippet button, or highlight the statement and hit the execute button. I.E.:
edit table_a where id=123
works fine, but
edit table_a where
throws an error, and
ignores the where clause entirely.
