Falha ao tentar deletar notícia

joãopedropereira · Fevereiro 3, 2010

Olá, amigos! Quando eu clico em deletar, para deletar a notícia do banco de dados, aparece o erro a seguir:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '@yahoo.com.br' at line 1

O que pode estar errado na query?

Pode ser erro de digitação, erro na hora de criar a instrução entre outros N motivos.

Imprima a query antes de executar e procure por erro de sintaxe (falta ou sobra de vírgula, falta ou sobra de aspa, ponto fora do lugar).
