Resolved C# Mysql Query (Select) return wrong result compare to Mysql Workbench

I've got an little issue with SQL query for an MySQL db.
Here is my query :
SELECT *
FROM myTable.requests
WHERE (myAccount= 'test')
AND MONTH(Date) = MONTH(CURRENT_DATE())
AND YEAR(Date) = YEAR(current_date())
AND (State = 'Closed')
group by Date;
This SQL return 3 rows in Workbench.
With y C# code the result is 16050 (!!)
What am I missing ?
'''
MySqlConnection mySqlConnection = mySQLEngineObj.GetConnectionObject();
int myRecordsCount = 0;
if (mySqlConnection == null)
return -1;
else {
myCommand.CommandText = "SELECT * FROM myTable.requests " +
"WHERE ((myAccount= #account) " +
"AND MONTH(requests.Date) = MONTH(NOW()) " +
"AND YEAR(requests.Date) = YEAR(NOW()) ) " +
"AND requests.State = #state " +
"GROUP BY requests.Date";
myCommand.Parameters.AddWithValue("#state", "Closed");
myCommand.Parameters.AddWithValue("#account", user.name);
MySqlDataReader test = myCommand.ExecuteReader();
if (test.HasRows)
{
test.Read();
}
}
'''
Code test.GetInt32(0) return an wrong result.
Any idea?

Slow performance importing MS Access database into SQL Server

I have a problem with importing items from an MS Access .mdb database file into SQL Server. I wrote a C# application in practice database that extrapolates the data in a .mdb database and places them in a table in a SQL Server database.
My problem is that the .mdb database contains about 300,000 articles which are to be inserted with all of the controls inside the SQL Server database. The .mdb file is selected by the user.
How can I speed up the import of the articles?
This is my C# code:
dbConn = new OleDbConnection(#"Provider = Microsoft.Jet.OLEDB.4.0; Data Source=" + dialog.FileName + "; Persist Security Info = False; Jet OLEDB:Database Password = " + textBoxPwdComet.Text + "; Mode = Share Deny None");

Consider using SqlBulkCopy. Since you are running sql queries I would suggest you'd work server side as much as possible. Create a temp table in Sql Server, add all records to a datatable or array of datarows and use SqlBulkCopy to import. I think that is the fastest way to move all records to Sql Server.
From there you can synchronize the two tables in Sql Server with only a few queries.

I would use SqlBulkCopy ...
dbConn = new OleDbConnection(#"Provider = Microsoft.Jet.OLEDB.4.0; Data Source=" + dialog.FileName + "; Persist Security Info = False; Jet OLEDB:Database Password = " + textBoxPwdComet.Text + "; Mode = Share Deny None");
SqlConnection conn2 = db.apriconnessione();
string query = "SELECT CODMARCA,CODART,DESCR,UM,PRZNETTO,PRZCASA,DATAAGG FROM ARTICOLI";
OleDbDataAdapter da = new OleDbDataAdapter(query,dbConn);
DataTable dt = new DataTable();
da.Fill(dt);
conn2.Open();
SqlBulkCopy bulk = new SqlBulkCopy(conn2);
bulk.DestinationTableName = "ARTICOLI";
bulk.WriteToServer(dt);
conn2.close();

How to convert mysql query into acceptable c# string?

Im creating columns using mysql dynamically if column doesnt exist.. I got the code which works in mysql console but when it comes to c# its giving me "Fatal encountered during command execution"
SET #preparedStatement = (SELECT IF(
(SELECT COUNT(*)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE table_name = 'tableName'
AND table_schema = DATABASE()
AND column_name = 'colName'
) > 0,
"SELECT 1",
"ALTER TABLE `tableName` ADD `colName` TINYINT(1) NULL DEFAULT '0';"
));
PREPARE alterIfNotExists FROM #preparedStatement;
EXECUTE alterIfNotExists;
DEALLOCATE PREPARE alterIfNotExists;
above code i converted into c# string as
string qry = "SET #preparedStatement = ( SELECT IF( (SELECT count(*) FROM information_schema.COLUMNS WHERE TABLE_SCHEMA = 'attendance' AND TABLE_NAME = '" + tname + "' AND COLUMN_NAME = '" + code + "_C' ) > 0, \"SELECT 1', \"ALTER TABLE " + tname + " ADD " + code + "_C int(3) NOT NULL default '0'; \" )); PREPARE alterIfNotExists FROM #preparedStatement; EXECUTE alterIfNotExists; DEALLOCATE PREPARE alterIfNotExists;";
what's the error getting?
Execution Code:
private void columnCreate_Load(object sender, EventArgs e)
{
string tname = "bca_i"; //for temprory
string code = "BCAXX";//for temprory
string qry = #"SET #preparedStatement = ( SELECT IF( (SELECT count(*) FROM information_schema.COLUMNS WHERE TABLE_SCHEMA = 'attendance' AND TABLE_NAME = '" + tname + "' AND COLUMN_NAME = '" + code + "_C' ) > 0, \"SELECT 1', \"ALTER TABLE " + tname + " ADD " + code + "_C int(3) NOT NULL default '0'; \" )); PREPARE alterIfNotExists FROM #preparedStatement; EXECUTE alterIfNotExists; DEALLOCATE PREPARE alterIfNotExists;";
try
{
using (MySqlConnection conn = new MySqlConnection(ConStr))
{
conn.Open();
using (MySqlCommand cmd = new MySqlCommand(qry, conn))
{
cmd.ExecuteNonQuery();
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}

The part
\"SELECT 1', \"A
does not match your original query at
"SELECT 1",
"A
Do you spot it? You replaced the " after 1 by an '.

I just figured other way for checking column exist.. Just used below query and checked if the column exists iterating through the loop of columns
string last_col = "SELECT COLUMN_NAME FROM information_schema.COLUMNS WHERE TABLE_SCHEMA = 'attendance' AND TABLE_NAME ='" + subCodeText.Text + "'";
where attendance is database and subCodeText.Text is my table name.

select rows by datetime in sqlite

I am trying to select rows which are inbetween a startdate and an enddate in c# with sqlite.
my dates are formatted like this:
2015-05-16T17:22:04.920+02:00
which should be a valid format for sqlite (ref: http://www.sqlite.org/lang_datefunc.html)
i am trying to select the row like this:
string CmdString = "SELECT * FROM " + tablename + "WHERE DATETIME(timekey) >= DATETIME('2015-05-16T17:22:04.920+02:00') AND DATETIME(timekey) <= DATETIME('2015-05-16T17:24:04.920+02:00')";
SQLiteCommand cmd = new SQLiteCommand(CmdString, con);
SQLiteDataAdapter sda = new SQLiteDataAdapter(cmd);
DataTable MatchDt = new DataTable();
sda.Fill(MatchDt);
The Error i get is:
SQLiteException: SQL logic error or missing database
What am I doing wrong?

You are missing a space char before the where:
string CmdString = "SELECT * FROM " + tablename + " WHERE DATETIME(timekey) >= DATETIME('2015-05-16T17:22:04.920+02:00') AND DATETIME(timekey) <= DATETIME('2015-05-16T17:24:04.920+02:00')";
And I would reccomend using the BETWEEN operator:
string CmdString = "SELECT * FROM " + tablename + " WHERE DATETIME(timekey) BETWEEN DATETIME('2015-05-16T17:22:04.920+02:00') AND DATETIME('2015-05-16T17:24:04.920+02:00')";

Program stops responding when deployed

I am having a problem where my application works fine on the development enviroment, but when deployed to a customer just hangs without tripping any exceptions.
In order to deploy I have to change the login details (removed) and sql statements to those shown, which I suppose might be the issue but I'd expect any sql syntex errors to throw an exception. I have excluded infinite loops as a possibility (I think).
The only possibility I'm aware of is to use multithreading and hope the problem is solved, but I don't have that kind of time unless I can be certain that is the solution.
Frankly I'm at a loss and any tips / advice for extracting any kind of lead on the problem is appricated.
