I want to sync and up-to-date the local database and the remote database concurrently. The owner have four restaurants(A, B, C, D) at different places. He maintains same price for products and same quality in all four restaurants. So he uses remote database to change price which used to affect the changed price in all branches. All four branches and remote server have the same database structure and same tables(i.e : A branch has records also other branch. Every branch every tables are uniquely identified by id and branch field(id + branch as composite key).
Sample table (purchase)
+----+--------+------------+------------+-----+--------------------+---------------------+
| id | branch | item | unit_price | qty | added_on | last_updated |
+----+--------+------------+------------+-----+--------------------+---------------------+
| 1 | A | Pizza | 800 | 5 |2018-12-05T15:47:54 | 2018-05-11T15:47:54 |

| 2 | A | Chicken | 350 | 5 |2018-12-05T15:49:54 | 2018-05-11T15:50:54 |

I have the following code to extract newly added record and updated record (with the field added_on and last_updated) from local database then upload and import in remote database with a timer. Here the checked time to extract records from local database is stored in a file which will use by the timer.
Now, to-up-to-date the local database(download other branch records) in every branch how can I download the newly inserted records and updated records from the remote server?

When I run my program, there is no some error. But when I see to my database, there is no data inserted. So, How can I insert data using json c# ?
With the following code, only the first set of database commands are actually carried out to fruition (one table is dropped, others have a record deleted from them) IF the MessageBox.Show() call at the beginning of DropTablesAndDeleteFromTables() is commented out.
If I uncomment it, so that the user has to dismiss after each set of database manipulations (obviously not what I want in the version to be used by customers), all is well - all the tables are dropped, and references to them deleted, as desired. Why does interrupting the process in this way (computus interruptus?) make the difference between success and failure, and how can I have my pie and eat it, too (get all the database commands to succeed without bothering the user with N MessageBox.Show() dialogs to dismiss?

What is a workaround to let the process come up for air without forcing the user to play a role in the charade?
UPDATE
It seems to be a matter of how much time elapses between each set of database manipulations. When I changed this:
while (i < 100000)
... in PauseThatRefreshes() to this:
while (i < 10000000)
(with the MessageBox.Show() commented out) it worked! But that still makes me nervous. Is there a more "scientific" (elegant?) way to accomplish this?
Your code example is both too complicated, and incomplete. So I can't say for sure what's wrong.
But the symptom is a classic indication that you are a) running the code in question on the main GUI thread, and b) that code at some point winds up blocked waiting for the main GUI thread to do something else (i.e. deadlock).
The right way to fix it is to perform those operations on a different thread than the main GUI thread. This will most likely introduce new problems where you are accessing GUI elements from the operation, which you'll have to address by using your GUI API's "Invoke" mechanism.
I'm fairly new to both Unity and PHP, and I am currently working on a project where I can parse data from a MySQL database to Unity, using PHP.
I initially wanted to try and enable a method where the user can perhaps change the php script and enable it to choose a different table of data, however I was advised that it may be safer to list all variables within the php script and call it from Unity accordingly;
Display.php
$table = mysql_real_escape_string($_GET['table'], $db);
if ($table == "shoes") {
$query = "SELECT * FROM `shoes` ORDER by `price` ASC LIMIT 10";
elseif ($table == "sneakers") {
$query = "SELECT * FROM `sneakers` ORDER by `price` ASC LIMIT 10";
$result = mysql_query($query) or die('Query failed: ' . mysql_error());
$num_results = mysql_num_rows($result);
for($i = 0; $i < $num_results; $i++)
{
$row = mysql_fetch_array($result);
echo $row['shopname'] . "\t" . $row['price'] . "\n";
}
I'm having trouble calling the php and choosing the table that I want to select, I am pretty new to this, so I apologise if this seems completely incompetent to you guys.
Here is the my Unity Script;
HSController.cs
void Start()
{
StartCoroutine(GetScores());
}
// remember to use StartCoroutine when calling this function!
IEnumerator PostScores(string name, int score)
{
string hash = Md5Sum(name + score + secretKey);
string post_url = addScoreURL + "name=" + WWW.EscapeURL(name) + "&score=" + score + "&hash=" + hash;
WWW hs_post = new WWW(post_url);
yield return hs_post; // Wait until the download is done
if (hs_post.error != null)
{
print("There was an error posting the high score: " + hs_post.error);
}
}
IEnumerator GetScores()
{
gameObject.guiText.text = "Loading...";
WWW hs_get = new WWW(highscoreURL);
yield return hs_get;
if (hs_get.error != null)
{
print("There was an error getting the high score: " + hs_get.error);
}
else
{
gameObject.guiText.text = hs_get.text; // this is a GUIText that will display the scores in game.
}
}
Any help or a point in the right direction would be great!
Kind Regards
Let me try to rewrite this into a working example:
C#
void Start() {
StartCoroutine(GetData());
}
IEnumerator GetData() {
gameObject.guiText.text = "Loading...";
WWW www = new WWW("http://yoururl.com/yourphp.php?table=shoes"); //GET data is sent via the URL
while(!www.isDone && string.IsNullOrEmpty(www.error)) {
gameObject.guiText.text = "Loading... " + www.Progress.ToString("0%"); //Show progress
yield return null;
}
if(string.IsNullOrEmpty(www.error)) gameObject.guiText.text = www.text;
else Debug.LogWarning(www.error);
}
PHP
<?php
//DB connection goes here
if ($_REQUEST['table'] === "shoes") { //I'm using REQUEST instead of GET, so it will work with both GET and POST
$query = "SELECT * FROM `shoes` ORDER by `price` ASC LIMIT 10";
} elseif ($_REQUEST['table'] === "sneakers") {
$query = "SELECT * FROM `sneakers` ORDER by `price` ASC LIMIT 10";
}
$result = mysql_query($query) or die(mysql_error());
while ($row = mysql_fetch_assoc($result)) {
echo $row['shopname'] . "\t" . $row['price'] . "\n";
}
?>
Hope this helps!
I am working on a project in which i read multiple field from an excel file and save them in db.How to show multiple errors messages on a page if user enters wrong value. Aspose.cells is used for reading data.My code is
public List<Data> ImportFromExcel(Stream bytes, out bool isFine)
{
isFine = true;
DateTime DOJ;
List<Data> list = new List<Data>();
DataTable dt = new DataTable();
Workbook workBook = new Workbook();
workBook.Open(bytes);
Worksheet workSheet = workBook.Worksheets[0];
try
{
dt = workSheet.Cells.ExportDataTable(0, 0, workSheet.Cells.MaxRow + 1, workSheet.Cells.MaxColumn + 1, true);
}
catch (Exception ex)
{
isFine = false;
ShowMessage("Your file has some invalid formats of data. Please review it and try again.", MessageType.Error, true);
return null;
}
try
{
int i = 1;
foreach (DataRow reader in dt.Rows)
{
if (reader["LetterId"].ToString().Length > 75)
{
isFine = false;
ShowMessage("In Row Number " + i + " Letter Id cannot exceed 75 characters.", MessageType.Error, true);
return null;
}
if (reader["Subject"].ToString().Length > 75)
{
isFine = false;
ShowMessage("In Row Number " + i + " Subject cannot exceed 75 characters.", MessageType.Error, true);
return null;
}
.
.
.
Show message method shows only single error message.
You could create an empty list of strings, and then each time you encounter an error just add it to the list. Then once you have all the errors in your list, you can just do this:
string allErrors = string.Empty;
foreach (string err in errorList)
{
allErrors += err + "<br />";
}
if (allErrors != string.Empty)
{
ShowMessage(allErrors);
}
I am inserting bulk data(serial number,pin number) to DB.Before inserting,the data from datatable is binded into XML tag.Here the pin number is encrypted one...as follows,
strXml = "<?xml<pre lang="c#"></pre> version=" + #"""1.0"" encoding=" + #"""iso-8859-1""?><batch>";
strPinXml =strPinXml + "<data cardid="+#"""" +strid+#""""+" pinnumber=" + #"""" + myRC4Engine.CryptedText + #"""" + "></data>";
strXml = strXml + strPinXml + "</batch>";
Problem is after inserting into db, to verify whether the actual pinnumber(encrypted format in db) is inserted, i decrypted the pinnumber and found that,
The first digit in all data are displaced by (’)single quote and last
digit for some pinnumber is empty (if the pinnumber is-œA_¡/Ì·ÞvËÛ
(ie)ending in Û for that pins last digit is empty).
Please note that i'am using SQL server 2000 in this application
Please provide the solution to resolve this issue

strid = strCardid + strBatchid + lobjbaseBatchDetail[2].ToString();
XElement data = new XElement("data");
data.Add(new XAttribute("cardid", strid));
