Question

I had try several type of date format and yet, I stil can’t get it right.

Below are the coding which had been writen

Dim serverDate As String = Format(Now(), "DD-MM-YYYY")
strNew &= "INSERT INTO Staff ("
            strNew &= "full_name"
            strNew &= ", login_id"
            strNew &= ", passwd"
            strNew &= ", last_update"
            strNew &= ") VALUES ("
            strNew &= "'" & txt_Name.Text & "'"
            strNew &= ", '" & txt_Login.Text & "'"
            strNew &= ", '" & txt_Password.Text & "'"
            strNew &= ", (STR_TO_DATE('" & serverDate & "', '%d-%m-%Y'))"
            strNew &= ")"

Any idea what had I missed out?.. Helps are much appreciated..

Edit #1:
Forgot to add in the error message
“Incorrect datetime value :’DD-09-YYYY’ for function str_to_date”

You are using hard-coded sql string so you need to use yyyy-MM-dd format date.

Dim serverDate As String = DateTime.Now.ToString("yyyy-MM-dd")

strNew &= "INSERT INTO Staff ("
            strNew &= "full_name"
            strNew &= ", login_id"
            strNew &= ", passwd"
            strNew &= ", last_update"
            strNew &= ") VALUES ("
            strNew &= "'" & txt_Name.Text & "'"
            strNew &= ", '" & txt_Login.Text & "'"
            strNew &= ", '" & txt_Password.Text & "'"
            strNew &= ", '" & serverDate & "'"
            strNew &= ")

Yes it is incorrect format. It should be

Format(Now(), "dd-MM-yyyy")

Take a look at this code-snippet

cmd=new MySqlCommand()
cmd.Connection=cn
cmd.CommandText="INSERT INTO Staff (?full_name,?login_id,?passwd,?last_update)"
cmd.Parameters.Add("?full_name", MySql.Data.MySqlClient.MySqlDbType.VarChar).Value =txt_Name.Text
cmd.Parameters.Add("?login_id", MySql.Data.MySqlClient.MySqlDbType.VarChar).Value =txt_Login.Text
cmd.Parameters.Add("?passwd", MySql.Data.MySqlClient.MySqlDbType.VarChar).Value =txt_Password.Text
cmd.Parameters.Add("?last_update", MySql.Data.MySqlClient.MySqlDbType.DateTime).Value =DateTime.Now

cn.Open()
cmd.ExecuteNonQuery()
cn.Close()

Off-topic: Don’t use hard-coded sql string. Use parameterized sql statement.
