Question

我正在尝试使用以下代码从sql表中的excel文件中插入数据

foreach (var sheetName in GetExcelSheetNames(connectionString))
{
    using (OleDbConnection con1 = new OleDbConnection(connectionString))
    {
        var dt = new DataTable();

        string query = string.Format("SELECT  * FROM [{0}]", sheetName);

        con1.Open();

        OleDbDataAdapter adapter = new OleDbDataAdapter(query, con1);
        adapter.Fill(dt);

        using (SqlConnection con = new SqlConnection(consString))
        {
            con.Open();
            for (int i = 2; i < dt.Rows.Count; i++)
            {

                for (int j = 1; j < dt.Columns.Count; j += 3)
                {
                    var s = dt.Rows[i][0].ToString();
                     s = s.Replace(",", string.Empty);
                    s = s.Substring(s.IndexOf(' ') + 1);
                    var dt1 = DateTime.Parse(s, CultureInfo.GetCultureInfo("fr-FR"));
                    var s1 = dt.Rows[i][j].ToString();
                    s1 = s1.Replace(" ", string.Empty);
                    var s2 = dt.Rows[i][j + 1].ToString();
                    s2 = s2.Replace(" ", string.Empty);
                    SqlCommand command = new SqlCommand("INSERT INTO [Obj CA] (CA,[VAL MRG],[Rayon],[Date],[Code Site]) VALUES(@ca,@val,'" + dt.Rows[0][j].ToString() + "', @date ,'" + sheetName + "')", con);
                    command.Parameters.Add("@date", SqlDbType.Date).Value = dt1;
                    command.Parameters.AddWithValue("@ca", s1);
                    command.Parameters.AddWithValue("@val", s2);
                    command.ExecuteNonQuery();
                }
            }

            con.Close();
        }
}

Answer 1

当您尝试将工作表名称插入[Obj CA]时，会触发您的错误。可能它有价值＆＃39; sheet01 $＆＃39;并且SQL Server无法解析$ char。

尝试重命名工作表或删除$ char，然后再将其插入表格。
