INSERT INTO in MySQL not working but no errors? - mysql

Question

I somehow can't insert data into my MySQL database but I know there's no trouble with the query cause there is no error message and it can make it as far as the Success message box. I think the query is right for MySQL but it is not the specific one that I should use for INSERT INTO.
Here's my code:
Imports MySql.Data.MySqlClient
Public Class Register
Dim ServerString As String = "Server=localhost; UserId =root; Password = ; Database = gym;"
Dim MysqlConn As MySqlConnection = New MySqlConnection
Dim COMMAND As MySqlCommand
Dim password, pass As String
Dim member As Integer
Private Sub Register_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.CenterToParent()
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
MysqlConn.ConnectionString = ServerString
Dim READER As MySqlDataReader
password = TextBox2.Text
pass = TextBox3.Text
confirm(password, pass)
If TextBox1.Text = Nothing Or TextBox2.Text = Nothing Or TextBox3.Text = Nothing Or TextBox4.Text = Nothing Or TextBox5.Text = Nothing Or TextBox6.Text = Nothing Or DateTimePicker1.Text = Nothing Or RadioButton1.Checked = False And RadioButton2.Checked = False Then
MsgBox("Please Fill your Information Completely")
Else
MysqlConn.ConnectionString = ServerString
Try
MysqlConn.Open()
Dim query As String
query = "select * from gym.user where user_name ='" & TextBox1.Text & "'"
COMMAND = New MySqlCommand(query, MysqlConn)
READER = COMMAND.ExecuteReader
Dim count As Integer
While READER.Read
count = count + 1
End While
MysqlConn.Close()
If count > 0 Then
MsgBox("User Already Exists")
Else
MysqlConn.Open()
query = "INSERT INTO gym.user(user_name,user_password,user_firstname,user_lastname,user_birthday,user_contact,user_membership) VALUES ('" & TextBox1.Text & "', md5('" & TextBox2.Text & "') ,'" & TextBox4.Text & "','" & TextBox5.Text & "','" & DateTimePicker1.Value.Date & "','" & TextBox6.Text & "','" & member & "')"
COMMAND = New MySqlCommand(query, MysqlConn)
MsgBox("USER REGISTERED")
MysqlConn.Close()
End If
Catch ex As Exception
MsgBox(ex.Message)
Finally
MysqlConn.Dispose()
End Try
End If
End Sub

You're missing ExecuteNonQuery statement:
query = "INSERT INTO gym.user(user_name,user_password,user_firstname,user_lastname,user_birthday,user_contact,user_membership) VALUES ('" & TextBox1.Text & "', md5('" & TextBox2.Text & "') ,'" & TextBox4.Text & "','" & TextBox5.Text & "','" & DateTimePicker1.Value.Date & "','" & TextBox6.Text & "','" & member & "')"
COMMAND = New MySqlCommand(query, MysqlConn)
COMMAND.ExecuteNonQuery()
