i hadnt logged into my site for a while and did just now and noticed an update to 3.5.0, i also had several extensions available for update. Now here's my question. I chose to to the major upgrade first PRIOR to doing an extension update and it error out with something along the lines of  SQL= i think. Went back to the main login and the update does seem to have gone through. So i checked my extensions list and noticed an update from my existing 1.2.4 to 1.3.1 with the changelog for 1.3.0 and 1.3.1 carry references to 3.5.0. Now, i'm not blaming anyone, i'm just wondering the following.
does that sql 0 error have a negative impact? if it does can it be easily fixed by manually running a certain sql command or should i do a site restore first, then update all my extensions and then update to 3.5.0?
