我尝试使用visual studio将新值插入到我的数据库中,这是我的代码:
SqlCommand cmd = new SqlCommand();
SqlConnection conn = new SqlConnection();
conn.ConnectionString = dbconnectionstring;
conn.Open();
cmd.Connection = conn;
cmd.CommandText = "INSERT INTO Data_ConfigInfo (TypeID, Name, ValidFromDate, ValidToDate, ValidFromSOP, ValidToSOP, Description)" +
"VALUES(@TypeID, @Name, @ValidFromDateTime, @ValidToDateTime, @ValidFromSOP, @ValidToSOP, @Description)";
cmd.Parameters.AddWithValue("TypeID", Logg.TypeID);
cmd.Parameters.AddWithValue("Name", Logg.Name);
if(Logg.ValidFrom.Equals(null)) {
cmd.Parameters.AddWithValue("@ValidFromDateTime", DBNull.Value);
}
else
{
cmd.Parameters.AddWithValue("@ValidFromDateTime", Logg.ValidFrom);
}
if (Logg.ValidTo.Equals(null))
{
cmd.Parameters.AddWithValue("@ValidToDateTime", DBNull.Value);
}
else
{
cmd.Parameters.AddWithValue("@ValidToDateTime", Logg.ValidFrom);
}
cmd.Parameters.AddWithValue("@ValidFromSOP", Logg.ValidFromSOP);
cmd.Parameters.AddWithValue("@ValidToSOP", Logg.ValidToSOP);
cmd.Parameters.AddWithValue("@Description", Logg.Description);
cmd.ExecuteNonQuery();
conn.close();
conn.dispose();
但是在
行cmd.ExecuteNonQuery();
我收到错误
ValidToDateTime和ValidFromDateTime的列名无效。
两者都是日期时间变量。我似乎无法找到错误。有任何想法吗?
这是我的数据表的外观
答案 0 :(得分:5)
您的数据库表格中包含ValidFromDateTime, ValidToDateTime
列,但INSERT
语句中的列列表中包含ValidFromDate, ValidToDate
。在这里发帖时你确定这不是一个错字吗?

你忘了'@'吗?
let currentHTML = stateToHTML(this.state.editorState.getCurrentContent());
currentHTML = currentHTML + "<li>" + value +"</li>"
let contentState = stateFromHTML(currentHTML);
this.setState({editorState : editorState.createWithContent(contentState)});
