As indicated earlier, you miss a quotation mark after fullname, but also:
- Try to always use backticks around fieldnames, it will save you a lot of
headache.
- In error messages like this, the error is 99% of the time on the left,
NOT the right.
- The extra quote is indeed not in your code, but the errormessage quotes a
part of your query, hence:
userid = '15'
becomes:
'userid = '15''
