尝试插入数据表的数组值时出现SQL语法错误

Question

I am having a SQL syntax error when I try to Insert in mysql database array values of a datatable named 'table'.

ERROR [42000] [MySQL][ODBC 3.51 Driver][mysqld-5.0.27-community-nt]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right.

Datatable = table;

Here's the code:

 for (int x = 0; x < table.Rows.Count; x++)
   {
      conn.Open();
      OdbcCommand command = new OdbcCommand("INSERT INTO jevslimporttemp(JevSLImportTempCode, JevSLImportTempDescription, JevSLImportTempAmount)VALUES('" + table.Rows[x][0].ToString() + "','" + table.Rows[x][1].ToString() + "','" + Convert.ToDouble(table.Rows[x][2].ToString()) + "');", conn);
      command.ExecuteNonQuery();
      conn.Close();
   }

Answer 1

You most likely have values in your variable interfering with the sql, like a single quote or question mark. You should parameterize your query.

OdbcCommand command = new OdbcCommand("INSERT INTO jevslimporttemp(JevSLImportTempCode, JevSLImportTempDescription, JevSLImportTempAmount)VALUES(?, ?, ?);", conn);

command.Parameters.AddWithValue("JevSLImportTempCode", table.Rows[x][1].ToString());
command.Parameters.AddWithValue("JevSLImportTempDescription", table.Rows[x][1].ToString());
command.Parameters.AddWithValue("JevSLImportTempAmount", Convert.ToDouble(table.Rows[x][2].ToString()));

Answer 2

It looks like all three of your fields are not string type. From the field names my guess is the third field is numeric. Try without quote for the third field:

OdbcCommand command = new OdbcCommand("INSERT INTO jevslimporttemp(JevSLImportTempCode, JevSLImportTempDescription, JevSLImportTempAmount)VALUES('" + table.Rows[x][0].ToString() + "','" + table.Rows[x][1].ToString() + "'," + Convert.ToDouble(table.Rows[x][2].ToString()) + ");", conn);
