推荐答案

除了Anuj Banka所说的以外:您的SQL语句是由字符串串联组装的操作，因此容易受到SQL注入攻击.您的问题很可能是由以下事实引起的:在注释或标记内的某个地方存在一个单引号字符，这会破坏您幼稚地构造的SQL.使用 SqlCommand [参数 [ SqlParameter [

Apart from what Anuj Banka already stated: Your SQL statement is assembled by string concatenation operations and is thus prone to SQL injection attacks. Your problem most likely arises from the fact that somewhere inside a comment or a mark there is a single quote character which will corrupt your naively constructed SQL. Use the SqlCommand[^].Parameters[^] in conjunction with the SqlParameter[^] class.
