Question

似乎我总是有错误"syntax error in INSERT into"。你能告诉我为什么吗？

Dim conn As New System.Data.OleDb.OleDbConnection()
conn.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\Bro_Proj.accdb"
conn.Open()
Dim sql As String = "INSERT INTO Order(Stud_ID, BookName, Quantity, sale, DateOfOrder, TimeOfOrder)  VALUES ('" & TextBox1.Text & "', '" & ComboBox3.Text & "', '" & NumericUpDown1.Value & "','" & TextBox10.Text & "',' " & TextBox8.Text & "','" & TextBox9.Text & "') ;"
Dim sqlc As New System.Data.OleDb.OleDbCommand(sql, conn)
sqlc.ExecuteNonQuery()
conn.Close()

Answer 1

Quantity Data类型是Integer，因此您必须删除qyantity参数中的简单引号，真正的代码如下：

Dim sql As String = "INSERT INTO Order(Stud_ID, BookName, Quantity, sale, DateOfOrder, TimeOfOrder)  
VALUES ('" & TextBox1.Text & "', '" & ComboBox3.Text & "', " & NumericUpDown1.Value & ",'" & TextBox10.Text & "',' " & TextBox8.Text & "','" & TextBox9.Text & "')"

查询错误“INSERT中的语法错误”
