Question

System.Data.OleDb.OleDbConnection bes = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Users\JAMES DEAN\Documents\aha.mdb;User Id=admin; Password=;;");
System.Data.DataTable pc = new System.Data.DataTable();

System.Data.OleDb.OleDbDataAdapter save = new System.Data.OleDb.OleDbDataAdapter("SELECT * FROM Info (Quantity, Unit, Account, Description , Amount, Total Amount, [Date]) VALUES '"+ textBox1.Text +"','" +textBox2.Text +
            "','" + textBox3.Text + "','" + textBox4.Text + "','" + textBox5 + "','" + textBox6.Text+ "','" + dateTimePicker1.Value.ToString("MM/dd/yyyy") + "','" ,bes);
save.Fill(pc);
dataGridView1.DataSource = pc;

谢谢：D

System.Data.OleDb.OleDbCommand save = new System.Data.OleDb.OleDbCommand(
    "Insert into Info (Quantity, Unit, Account, Description , Amount, Total Amount, Account Title, [Date]) VALUES '"
    + textBox1.Text +"','" 
    +textBox2.Text +"','" 
    + textBox3.Text + "','" 
    + textBox4.Text + "','" 
    + textBox5 + "','" 
    + textBox6.Text+ "','"
    + comboBox1.Text+"','" 
    + dateTimePicker1.Value.ToString("MM/dd/yyyy") + "','" ,bes);
save.ExecuteNonQuery();
bes.Close();

现在这是我的代码，我仍然得到错误TT

Answer 1

您正在混合两个查询Select和Insert

选择

SELECT Quantity, Unit, Account, Description , Amount, Total Amount, [Date] FROM Info

插入

Insert into Info (Quantity, Unit, Account, Description , Amount, Total Amount, [Date]) VALUES ...

另外
1.列之间不能有空格。
2.请使用参数化查询来防止SQL注入。

如何在FROM子句中解决此语法错误？
