使用c#和asp.net将sql插入到access db时出现语法错误

I get an error on the line

我在线路上出错了

cmd.ExecuteNonQuery();

which says

说

Syntax error in INSERT INTO statement

INSERT INTO语句中的语法错误。

I think my query should be valid, I don't understand the problem and I've been working on it for hours. It's in the right order and putting [] around Users did not work for me, would appreciate help.

我认为我的问题应该是有效的，我不理解这个问题，我已经花了好几个小时在这个问题上。这是正确的顺序，并把[]周围的用户不为我工作，将感激帮助。

            OleDbConnection conn = new OleDbConnection(connStr);
            conn.Open();

            OleDbCommand cmd = new OleDbCommand(sql, conn);
            cmd.ExecuteNonQuery();

            conn.Close();
    }

3 个解决方案

#1

PASSWORD is a reserved keyword for MS-Access. Use it enclosed in square brackets

密码是MS-Access的保留关键字。用方括号括起来

    sql = "INSERT INTO Users(UserName, Email, [Password] ....

But please, change that sql text to use a parameterized query. Also, if you are able to send this command with the actual values your query remains open to Sql Injection vulnerability and a parsing problem could arise when your input string contains a single quote

但是请修改sql文本以使用参数化查询。另外，如果您能够将这个命令与实际值一起发送，那么您的查询仍然可以打开Sql注入漏洞，当您的输入字符串包含单引号时，可能会出现解析问题。

   sql = @"INSERT INTO Users(UserName, Email, [Password], Age, Country, Hobbie) 
           VALUES(?,?,?,?,?,?)";
   ....

   OleDbCommand cmd = new OleDbCommand(sql, conn);
   cmd.Parameters.AddWithValue("@p1", username);
   .... and so on for the other 5 parameters required by the query ....

#2

I think Password is a reserved word. use like [Password]

我认为密码是一个保留字。使用(密码)

Try this

试试这个

sql = "INSERT INTO Users(UserName,Email,[Password],Age,Country,Hobbie) VALUES('" + username + "','" + email + "','" + password + "'," + age + ",'" + country + "','" + skin + "')";

And this is not recommended. Use parameterized query. like below:

这是不推荐的。使用参数化查询。像下图:

 sql = "INSERT INTO Users(UserName, Email, [Password], Age, Country, Hobbie) 
           VALUES(@UserName,@Email,@Password,@Age,@Country,@Hobbie)";

   OleDbCommand cmd = new OleDbCommand(sql, conn);
   cmd.Connection = conn;
   cmd.CommandType = CommandType.Text;   
   cmd.Parameters.AddWithValue("@UserName", username);
   cmd.Parameters.AddWithValue("@Email", Email);
   cmd.Parameters.AddWithValue("@Password", Password);
   cmd.Parameters.AddWithValue("@Age", Age);
   cmd.Parameters.AddWithValue("@Country", Country);
   cmd.Parameters.AddWithValue("@Hobbie", Hobbie);

use [Password] instead of Password

使用[密码]代替密码
