Question

我有这个表主页：

"Record ID",Status,Placement,Private,Category,Note,Description,"Due Date",Completed,Priority,Blob,"Repeat On Complete Date","Complete Date","Alarm Set","Alarm Time","Alarm Advance","Repeat Start Date","Repeat Info"

示例条目

14340973,132,2147483647,False,3,Any note,Any Description,1956556799,False,1,System.Byte[],False,1956556799,False,1956470400,0,0,

在SQL中插入的正确语法是什么？

这就是我所做的：

string strSQL = "INSERT INTO Main ( Record ID , Status , Placement , Private , Category , Note , Description , Due Date , Completed , Priority , Blob , Repeat On Complete Date , Complete Date , Alarm Set , Alarm Time , Alarm Advance , Repeat Start Date , Repeat Info ) VALUES (@Rid,132, 2147483647, False,, @Kat, @Not, @Bes, 1956556799, False, @Pri, '', 1956556799, False, 1956470400, 0, 0, '', '')"; 
        MessageBox.Show(strSQL);
        OleDbCommand cmd = null;
        try
        {
            cmd = new OleDbCommand(strSQL, AufgabenVerbindung);
        }
        catch (Exception vvxc)
        {
            Console.WriteLine(vvxc.Message);
        }
        OleDbParameter Kat, Not, Bes, Pri, Rid;
        Rid = cmd.Parameters.Add("@Rid", OleDbType.BigInt);
        Kat = cmd.Parameters.Add("@Kat", OleDbType.TinyInt);
        Not = cmd.Parameters.Add("@Not", OleDbType.VarChar);
        Bes = cmd.Parameters.Add("@Bes", OleDbType.VarChar);
        Pri = cmd.Parameters.Add("@Pri", OleDbType.TinyInt);
        Rid.Value = Record_ID + 1;
        Kat.Value = 5;
        Not.Value = txtNotiz.Text;
        Bes.Value = txtBeschreibung.Text;
        Pri.Value = pri;
        cmd.ExecuteNonQuery();

cmd.ExecuteNonQuery（）抛出异常

Answer 1

我看到两个问题。首先你有空格的列名，如果这是用于SQL Server尝试在[]中包装它们，如下所示：

string strSQL = "INSERT INTO Main ( [Record ID] , Status , Placement , Private , Category , Note , Description , [Due Date] , Completed , Priority , Blob , [Repeat On Complete Date] , [Complete Date] , [Alarm Set] , [Alarm Time] , [Alarm Advance] , [Repeat Start Date] , [Repeat Info] ) VALUES (@Rid,132, 2147483647, False,, @Kat, @Not, @Bes, 1956556799, False, @Pri, '', 1956556799, False, 1956470400, 0, 0, '', '')";

如果这是MySQL，我相信你需要用`

来删除列名

此部分：False,, @Kat,无效。尝试删除额外的逗号或在其中放置一个值。

Answer 2

用[]包含空格

的字段换行

例如

[Record ID]和[Due Date]

在这种情况下，正确的SQL语法
