sintaxe incorreta perto de '' aspas não fechadas após a sequência de caracteres ')'
Criei um formulário da Web usando c # no Visual Web Dev 2010 Express e ele contém caixas de texto / rótulos (com base nas caixas de seleção), mas quando executo o código, falha ao executar o comando SQL. Consegui que o código funcionasse antes de usar apenas três caixas de texto, mas parece não funcionar quando eu expando o código.
Coisas que tentei:
Ao pesquisar no Google, alguém disse algo sobre as aspas serem um problema (e o erro reflete isso), mas se eu remover todas as citações do comando SQL, ele falha, mas meus pensamentos eram: sempre tinha que ser.'"+datahere+"' isso é verdade?
Também cito todo o meu código para o formulário da web em questão abaixo do erro. O erro fica assim quando executo uma 'depuração':
Sintaxe incorreta perto de 't'. Aspas não fechadas após a sequência de caracteres ')'.
Descrição: ocorreu uma exceção não tratada durante a execução da solicitação da web atual. Revise o rastreamento de pilha para obter mais informações sobre o erro e onde ele se originou no código.
Detalhes da exceção: System.Data.SqlClient.SqlException: sintaxe incorreta próxima a 't'. Aspas não fechadas após a sequência de caracteres ')'.
Erro de origem:
