My SQL statement is in the form of "select name, address, age from table". But the actual statement is simply a much longer form i.e. it has 28 columns.

So does the error also appear with a simple SQL statement? <op>And can you reproduce it with $sqlexe->fetchrow_array instead of bind? (If not, it's likely a problem with the parameter binding). What happens if you use references to scalars instead of references to array elements for binding?
