我想在C#中的現有MS Access數據庫表中添加一個新行。但是,當我調用DataAdapter的Update方法時,出現了「INSERT INTO語句中的語法錯誤」。我的代碼是:當我調用DataAdapter.Update()時,爲什麼此C#代碼會生成語法錯誤?
try
{
// Open the database
OleDbCommand mySelectCommand = new OleDbCommand(strAccessSelect, myAccessConn);
OleDbDataAdapter myDataAdapter = new OleDbDataAdapter(mySelectCommand);
OleDbCommandBuilder myCommandBuilder = new OleDbCommandBuilder(myDataAdapter);
myAccessConn.Open();
// Get Analogue table
int rowCount = myDataAdapter.Fill(myDataSet, "Analogue");
Console.WriteLine("Row Count: " + rowCount);
DataTable analogues = myDataSet.Tables["Analogue"];
analogues.PrimaryKey = new DataColumn[] { analogues.Columns["Name"] };
// Create a new row.
System.Data.DataRow newRow;
newRow = analogues.NewRow();
newRow["Name"] = "My new row";
newRow["Area"] = "System";
newRow["Description"] = "My new row, created by me!";
analogues.Rows.Add(newRow);
myDataAdapter.InsertCommand = myCommandBuilder.GetInsertCommand();
myDataAdapter.UpdateCommand = myCommandBuilder.GetUpdateCommand();
Console.WriteLine("Insert Command: " + myDataAdapter.InsertCommand.ToString());
Console.WriteLine("Update Command: " + myDataAdapter.UpdateCommand.ToString());
myDataAdapter.Update(myDataSet, "Analogue");
}
catch (Exception ex)
{
Console.WriteLine("Error: Failed to manipulate the DataBase.\n{0}", ex.ToString());
return;
}
finally
{
myAccessConn.Close();
}
我已刪除大多數列從表簡潔,但所有的列標題都在報價,他們沒有包含任何空格,且都不保留字。我沒有刪除的是Access關鍵字,但我注意到「NAME」和「Description」是。我不相信這會導致我的問題,因爲我已經能夠修改現有行中「說明」列中的文本。
命令生成器生成以下對我來說這似乎不太對勁:
System.Data.OleDb.OleDbCommand
我需要手動建立這個命令?如果是這樣,我應該使用插入或更新 - 適配器只有一個更新方法,據我所知可以調用更新或插入?
這裏是堆棧跟蹤與錯誤:
System.Data.OleDb.OleDbException (0x80040E14): Syntax error in INSERT INTO statement.

'Console.WriteLine(myDataAdapter.InsertCommand.CommandText);'現在你打印的只是類的名稱而不是屬性commandtext – Steve
