C++ :: Get DateTime From A Table
Aug 5, 2013
I'd like to get a a field name "eventDateTime" from a DB table and its storage is datetime year to fraction (3) . I have created a function return results like this but i put its type as a int:
int Status::GetEventFromSQL(){
int j = 0;
int eventTime = 0;
MYSQL_ROW myROW;
MYSQL_RES *myRES = NULL;
[code]....
"eventTime " is also declared in another sheet .h as an int. In execution i have a big and negative number ; I know that's because of the int type but i'm bigenner in C++...

I have an application in C sharp that searches for a record in a sql database using a datetimepicker,the output is displayed in a datagridview.When I execute it I got a blank datagridview with empty columns.I can not view the content and I don't get any error message.
Here is my code:
DataTable dt=new dataTable();
SqlDataAdapter sda=new sqldataadapter("select * from Delivery where convert
(char(20),Delivery_Date,112)='"+ dateTimePicker1.value.Date,con);
//con is sqlconnection
Sda.Fill(dt);
Datagridview1.DataSource=dt;

I currently have a DatePicker in my xaml forum. In my constructor and class I have my dates as a DateTime object. I am currently trying to get my datepicker date to be passed into my constructor or maybe I have to convert the datepicker to a datetime object?
private void btnSave_Click(object sender, RoutedEventArgs e)
{
DateTime xxx = new DateTime();
xxx = Convert.ToDateTime(dateCurrent.SelectedDate);
//validate registration form
lifter = new User(txtFirstName.Text, txtLastName.Text, txtStartWeight.Text, genderStatus, xxx);

I have a DateTime field on a database it looks like this :
2014-10-21 14:34:37.697
I want to use it, as is, in an UPDATE statement something like:
UPDATE PayrollRuns SET IsProcessed = 'True' WHERE Date_Time_Triggered = '2014-10-21 14:34:37.697'
I must have the exact date & time as that uniquely identifies the record.
The problem I'm having is getting it off the database and into an C# variable without it being changed.
I can get it into a string but it changes it becomes:
21/10/2014 14:34:37
I've got it in an object. I've tried:
string date_Time_Triggered = databasesRow["Date_Time_Triggered"].ToString();
//
//and
//
var date_Time_Triggered = databasesRow["Date_Time_Triggered"];

I am trying to insert values from a form into my SQL database. Two of the fields in the SQL database are of type DateTime.
When trying to insert I am receiving the error "Conversion failed when converting date and/or time from character string."
The relevant code is as follows:
DateTime saveNow = DateTime.Now;
string sqlFormattedDate = saveNow.ToString("yyyy-MM-dd HH:mm:ss");
conn.Open();

I am converting unix timestamp to datetime format like this:
static readonly DateTime UnixEpoch = new DateTime(1970, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc);
static readonly double MaxUnixSeconds = (DateTime.MaxValue - UnixEpoch).TotalSeconds;
public static DateTime UnixTimeStampToDateTime(double unixTimeStamp) {
return unixTimeStamp > MaxUnixSeconds
? UnixEpoch.AddMilliseconds(unixTimeStamp)
: UnixEpoch.AddSeconds(unixTimeStamp);
}
use it:
Console.WriteLine("From UNIX do datetime 1300123800440 : " + UnixTimeStampToDateTime(1300123800440));
output: 14.03.2011 5:30 PM
Now i would like to have function which convert it back to unix timestamp but unfortuently my new function is cutting down last 3 digits for instance:
public static long UnixTimestampFromDateTime(DateTime date) {
long unixTimestamp = date.Ticks - new DateTime(1970, 1, 1).Ticks;
unixTimestamp /= TimeSpan.TicksPerSecond;
return unixTimestamp;
}
after use of it i am retrieving:
Console.WriteLine(UnixTimestampFromDateTime(Convert.ToDateTime("14.03.2011 5:30 PM")));
result:
1300123800

I am having an issue with my sort function. This is one part of the Hash table program. The main issue is that I am trying to sort the pointer table after all of the values have been entered. The ptr_sort function is not a class function and so I am therefore unable to use the class variables psize and pTable. Is there another way I should be trying this? it is a Vector should I use the sort() function from the vector class in STL?
#include "/home/onyuksel/courses/340/progs/13f/p9/util9.h"
#include "/home/onyuksel/courses/340/progs/13f/p9/hTable.h"
#ifndef H_TABLE1
#define H_TABLE1
void ptr_sort ( );

If a user enters a string of boolean algebra it will ouput the table.
I have input parsing, cycling through the combinations, and outputing working. However once i parse the input I am not sure what to do with it. I have thought of having it write the parsed input to a new file as a function and then use that function, but that seems bad.
How to dynamically create the function, how to implement it.
BTW This is a console function, if that changes anything.

I have written an SQL statement that would:
1) Count the number of rows in the table booking that are open and where the booking.postcode is "MK",
2) Take a note of the plot (in booking.plot_id), and then update the table plot.jobs with the value count.
For example running the SQL query when booking table has the following rows:
Would see the following highlighted values in plot.jobs being updated to 1:
I managed to resolve it with this code so far (note I am using Connector/Net):
public void RefreshPlot(){
string query =
"SELECT Count(*) AS count, plot_id FROM booking WHERE postcode='MK' AND status='open' GROUP BY plot_id";
var cmd = new MySqlCommand(query, _connection);
var da = new MySqlDataAdapter(cmd);
var dtCounts = new DataTable();
da.Fill(dtCounts);
[code]....
Currently, my code only checks for existing rows in the booking table and updates the plot table. However if the row gets deleted in the booking, then the changes are not reflected in the plot table.
Example: If we delete the row with plot.id=1 and plot.plot_id=4, then booking.plot_id should go back to being 0, if it was initially 1. At the moment, it doesn't. How would I update my SQL statement to better reflect this? In a sense, it should check for "non-existent" rows, i.e. the impact that the row plot.plot_id=4 & plot.id=1 has on booking.plot_id when deleted?

I retrieve a null value from a nullable sql datacolumn but when I pull it into a property it automatically gets the current datetime.
How will I go about making sure that this value returns a null and not the currentdatetime.

How do I convert date in integer format to DateTime without using DateTime?
I have tried:
Regex regex = new Regex(@"^(0[1-9]|1[012])(0[0-9]|1[0-9]|2[0-9]|3[01])(1[789]|[2-9][0-9])dd+$");
if (regex.IsMatch(txt_fromdate.Text) == true)
{
DateTime dt = DateTime.ParseExact(txt_fromdate.Text, "MMddyyyy", null);

I am a bit stumped with trying to write some code to get the tableadapter/binding source to "update" a current 'user' to the table.
I have the insert/delete methods working fine, but it's the updating that has got me screwed up.
Example of insert.
try
{
personTableAdapter.Insert(tFirstName.Text, tSurname.Text, Convert.ToDateTime(tDoB.Text), tPhone.Text, tAdd1.Text, tAdd2.Text, tSuburb.Text, tState.Text, tPostcode.Text, TeacherType.Text);
teacherTableAdapter.Insert(Convert.ToInt32(tTID1.Text), tRegNo.Text, tPassword.Text);
[Code]....
I also tried to do the updated string/original string with the tableadapter.update, but that didn't work either.

I have a problem with this function that adds a new value to the hash table or updates its data if the value already exists:
Code:
int tab_add(tab_disp *td, const object *value) the function should return:
TABDISP_OK if the value is correctly added, or TABDISP_ERROR if memory error, or TABDISP_INVALID if pointer td = NULL
The type of structure I am using is the following:
Code:
typedef struct {
char key[25];
char value[100];
} object;

I have a table in which data is populated via an element. However some elements can have a parent element
The client now wants all the children and parent elements to be next to each other row wise.
How can i add the child rows under the parent rows?
parents
foreach (var inspection in elemInspections) {
var date = db.INSPEVNT.Find(db.INSPEVNT.INSPKEY == inspection.INSPKEY && db.INSPEVNT.BRKEY == m_sBrKey);
var paircode = db.PON_ELEM_DEFS.Find(db.PON_ELEM_DEFS.ELEM_KEY == inspection.ELEM_KEY);
[Code] .....
how can i make it so the children go under the parent rows?

6 4
7 4 Code: I want to store ID values on the bases of same Group, like we do in Hash table (key, value) .
Group ID
2 0,1
3 2
4 3,4,5,6,7
so when i said key 2 it will give me 0,1. how can i do it. As first i thought that i can use array of array but then how i can store the value of key. Now I am thinking of hash but i don't know how I will store and retrieve these values.

I have recently run into a problem at work in regards to organizing information for some variables in a table and sorting them based on priority values...
For example:
Case ID: 0 1 2 3 4
1 (2 3) (1 2) (5 1) **the first number in the () is the priority*
2 **the second number is the variable id**
3
So from up above (I made it shorter than mine), I have a table with 8 columns for the different cases and 30 rows for the different conditions possible. I am trying to figure out a way to create some type of function that will be able to run through the row and pick the case with the highest priority first (from 1-8), and output the case ID, the priority, and the second number within the brackets.
I thought about creating a decoder that will sort the values and give an array with the outputs, but I know there must be a smarter way to sort the data.
