所以我试图将文本框和组合框控件中的文本插入到SQLite数据库中,但是我收到了语法错误
private void btnConfirm_Click(object sender, EventArgs e)
{
int indexID = 0;
string username = txtUsername.Text;
string password = txtPassword.Text;
string firstName = txtFirstName.Text;
string lastName = txtLastName.Text;
int age = cmbAge.SelectedIndex + 1;
string country = cmbCountry.Text;
string city = txtCity.Text;
string address = txtAddress.Text;
string breeds = txtBreeds.Text;
string notes = "None";
SQLiteConnection registerConnection = new SQLiteConnection("Data Source=|DataDirectory|/Resources/database.sqlite;Version=3;");
registerConnection.Open();
SQLiteCommand registerCommand = new SQLiteCommand("INSERT INTO users (indexID,username,password,firstname,lastname,age,country,city,address,tigerbreeds,notes)", registerConnection);
registerCommand.Parameters.AddWithValue("indexID", indexID); //0 for now, but we're going to change this later.
registerCommand.Parameters.AddWithValue("username", username);
registerCommand.Parameters.AddWithValue("password", password);
registerCommand.Parameters.AddWithValue("firstname", firstName);
registerCommand.Parameters.AddWithValue("lastname", lastName);
registerCommand.Parameters.AddWithValue("age", age);
registerCommand.Parameters.AddWithValue("country", country);
registerCommand.Parameters.AddWithValue("city", city);
registerCommand.Parameters.AddWithValue("address", address);
registerCommand.Parameters.AddWithValue("tigerbreeds", breeds);
registerCommand.Parameters.AddWithValue("tigerbreeds", notes);
registerCommand.ExecuteNonQuery();
}
有人知道如何解决这个问题吗?
System.Data.SQLite.dll中发生未处理的“System.Data.SQLite.SQLiteException”类型异常附加信息:SQL逻辑错误或“)”附近缺少数据库:语法错误

尝试更新到这个:
您必须构造有效的SQL查询 . Insert(columnName)Values(@paramName)
