I am doing what looks like a simple query basically doing a WHERE clause on the competition_id and the prize_type
$criteria = new CDbCriteria;
$criteria->select = 't.*, myuser.firstname, myuser.surname';
$criteria->join ='LEFT JOIN myuser ON myuser.user_id = t.user_id';
$criteria->condition = 't.competition_id = :competition_id';
$criteria->condition = 't.prize_type = :prize_type';
$criteria->params = array(":competition_id" => $competition_id);
$criteria->params = array(":prize_type" => "1");
$winners = CompetitionWinners::model()->findAll($criteria);
Can anyone suggest what is wrong with my code... I am expecting around 4 rows.. but get over 600?
I just want to do ...
WHERE competition_id = 123 AND prize_type = 1;
Is there a simple function to simply output the SQL query for this SINGLE CDbCriteria 'event'?
try this
$criteria = new CDbCriteria;
$criteria->select = 't.*, myuser.firstname, myuser.surname';
$criteria->join ='LEFT JOIN myuser ON myuser.user_id = t.user_id';
$criteria->condition = 't.competition_id = :competition_id AND t.prize_type = :prize_type';
$criteria->params = array(":competition_id" => $competition_id,":prize_type" => "1");
$winners = CompetitionWinners::model()->findAll($criteria);
Or you could use CDbCriteria::addCondition()
$criteria->addCondition('t.competition_id = :competition_id')
->addCondition('t.prize_type = :prize_type');

I am using model.GetType().GetProperties() with foreach to compare properties of 2 object of same class.
like this
foreach (var item in kayit.GetType().GetProperties())
{
var g = item.GetValue(plu);
var b = item.GetValue(kayit);
if (g is string && b is string&& g!=b)
{
a += item.Name + "*";
}
else if (g is DateTime&& b is DateTime&& g!=b)
{
a += item.Name + "*";
}
}
But the problem is even if they have the same value g!=b returns a true all the time. I have used a break point to prove this and they are literally same thing. Actually I am taking the value putting it in textbox then creating another class after button click and comaring to see the changed properties. So even if I don't change anything it doesn't read the mas equals. Can someone help me about this please?
more info:
I get the plu from database and populate my control with it:
txtorder.Text = plu.OrderNo;
dtporder.Value = nulldate(plu.OrderDate);
dtp1fit.Value = nulldate(plu.FirstFitDate);
dtp1yorum.Value = nulldate(plu.FirstCritDate);
dtp2fit.Value = nulldate(plu.SecondFitDate);
dtp2yorum.Value = nulldate(plu.SecondCritDate);
dtpsizeset.Value = nulldate(plu.SizeSetDate);
dtpsizesetok.Value = nulldate(plu.SizeSetOkDate);
dtpkumasplan.Value = nulldate(plu.FabricOrderByPlan);
txtTedarikci.Text = plu.Fabric_Supplier;
dtpkumasFP.Value = nulldate(plu.FabricOrderByFD);
dtpfabarrive.Value = nulldate(plu.FabricArrive);
dtpbulk.Value = nulldate(plu.BulkFabricDate);
dtpbulkok.Value = nulldate(plu.BulkConfirmDate);
dtpaccessory.Value = nulldate(plu.AccessoriesDate);
dtpaccessoryarrive.Value = nulldate(plu.AccessoriesArriveDate);
dtpcutok.Value = nulldate(plu.ProductionStartConfirmation);
dtpcutstart.Value = nulldate(plu.ProductionStart);
dtpshipmentdate.Value = nulldate(plu.ShipmentDate);
dtpshipmentsample.Value = nulldate(plu.ShipmentSampleDate);
dtpshippedon.Value = nulldate(plu.Shippedon);
nulldate is just a method where I change null values to my default value.
And this is what I do after button click:
var kayit = new uretim();
kayit.OrderNo = txtorder.Text.ToUpper();
kayit.OrderDate = vdat(dtporder.Value);
kayit.FirstFitDate = vdat(dtp1fit.Value);
kayit.FirstCritDate = vdat(dtp1yorum.Value);
kayit.SecondFitDate = vdat(dtp2fit.Value);
kayit.SecondCritDate = vdat(dtp2yorum.Value);
kayit.SizeSetDate = vdat(dtpsizeset.Value);
kayit.SizeSetOkDate = vdat(dtpsizesetok.Value);
kayit.FabricOrderByPlan = vdat(dtpkumasplan.Value);
kayit.Fabric_Supplier = txtTedarikci.Text;
kayit.FabricOrderByFD = vdat(dtpkumasFP.Value);
kayit.FabricArrive = vdat(dtpfabarrive.Value);
kayit.BulkFabricDate = vdat(dtpbulk.Value);
kayit.BulkConfirmDate = vdat(dtpbulkok.Value);
kayit.AccessoriesDate = vdat(dtpaccessory.Value);
kayit.AccessoriesArriveDate = vdat(dtpaccessoryarrive.Value);
kayit.ProductionStartConfirmation = vdat(dtpcutok.Value);
kayit.ProductionStart = vdat(dtpcutstart.Value);
kayit.ShipmentDate = vdat(dtpshipmentdate.Value);
kayit.ShipmentSampleDate = vdat(dtpshipmentsample.Value);
kayit.Shippedon = vdat(dtpshippedon.Value);
kayit.Status = true;
kayit.WrittenDate = DateTime.Now;
kayit.GuidKey = plu.GuidKey != null ? plu.GuidKey : Guid.NewGuid().ToString("N");
I have proven by breakpoint that values are actually same. But the != check retruns a true.
When you are doing
g != b
compiler doesn't know that these objects are strings to compare so it compares their references. You can do:
g.Equals(b) //be carefull if one of them is null
or
g.ToString() != b.ToString()
EDIT
You can compare them after you check the type:
if (g is string && b is string)
{
if( g.ToString() != b.ToString() ){
}
}
I just want to know whether this is the right way to post request:
$http.post(urlBase+'productattributecreate?'
+"&products_id"="1"
+"&attributes_id"=tab.attributeId
+"&attributes_values_id"=tab.attributeValueId
+"®ularPrice"=tab.regularPrice
+"&salesPrice"=tab.salePrice
+"&purchasePrice"=tab.purchasePrice
+"&stockStatus"=tab.stockStatus
+"&sttockQuantity"=tab.stockQuantity
+"&minquantitySales"=tab.minQuantitySales
+"&maxQuantitySales"=tab.maxQuantitySales
+"&productImage"="")
I think a more correct way would be:
$http.post('../productattributecreate', uploadData)
Where uploadData is an object containing all you the data:
var uploadData = {
products_id = '1',
attributes_id = tab.attributeId,
attributes_values_id = tab.attributeValueId,
regularPrice = tab.regularPrice,
salesPrice = tab.salePrice,
purchasePrice = tab.purchasePrice,
stockStatus = tab.stockStatus,
sttockQuantity = tab.stockQuantity,
minquantitySales = tab.minQuantitySales,
maxQuantitySales = tab.maxQuantitySales,
productImage = ''
};
Also... It would be better if you had clarified your question with more information.
I am working on codeigniter app to allow user to add edit and modify database.
I want to repeat this code by loop:
$db['db1']['hostname'] = 'localhost';
$db['db1']['username'] = 'ts4l_wp13';
$db['db1']['password'] = 'O&3D6c(0zD70.^9';
$db['db1']['database'] = 'ts4l_wp13';
$db['db1']['dbdriver'] = 'mysql';
$db['db1']['dbprefix'] = '';
$db['db1']['pconnect'] = FALSE;
$db['db1']['db_debug'] = TRUE;
$db['db1']['cache_on'] = FALSE;
$db['db1']['cachedir'] = '';
$db['db1']['char_set'] = 'utf8';
$db['db1']['dbcollat'] = 'utf8_general_ci';
$db['db1']['swap_pre'] = '';
$db['db1']['autoinit'] = TRUE;
$db['db1']['stricton'] = FALSE;
I do this:
#$get_data = mysql_query("SELECT * FROM `database_name`");
while($getdata = mysql_fetch_assoc($get_data)){
$id='db'.$getdata['id'];
$iid="$id";
$db["$iid"]['hostname'] = 'localhost';
$db["$iid"]['username'] = $getdata['username'];
$db["$iid"]['password'] = $getdata['password'];
$db["$iid"]['database'] = $getdata['name'];
$db["$iid"]['dbdriver'] = 'mysql';
$db["$iid"]['dbprefix'] = '';
$db["$iid"]['pconnect'] = FALSE;
$db["$iid"]['db_debug'] = TRUE;
$db["$iid"]['cache_on'] = FALSE;
$db["$iid"]['cachedir'] = '';
$db["$iid"]['char_set'] = 'utf8';
$db["$iid"]['dbcollat'] = 'utf8_general_ci';
$db["$iid"]['swap_pre'] = '';
$db["$iid"]['autoinit'] = TRUE;
$db["$iid"]['stricton'] = FALSE;
}
and this block.
// Loading db and running query.
$CI = &get_instance();
$this->db1 = $CI->load->database('db1', TRUE);
$this->db1->set($data);
$this->db1->insert($this->_table_name);
$id=$this->db1->insert_id();
I do this:
$this->load->model('mdb_m');
$dbms =$this->mdb_m->get();
if (count($dbms)) {
foreach ($dbms as $dbm) {
$mid=$dbm->id;
$dbc='db'.$mid;
$CI = &get_instance();
$this->db.$mid = $CI->load->database( "$dbc" , TRUE);
$this->db.$mid->set($data);
$this->db.$mid->insert($this->_table_name);
}
}
But it only insert at first database in the array then stop and retrive this error "You have specified an invalid database connection group."
you can get brief information of using multiple database from here.As you have mentioned.
https://ellislab.com/codeigniter/user-guide/database/connecting.html
for better approach you can make a loader file to load a database.I was in same problem and got the clear visualization from here
https://coderwall.com/p/_kyjvg/codeigniter-loading-up-multiple-databases
refer here and if still confused please revert back to me thankyou.
I have a functionality as follows:
When Any user logs in I want to connect to a particular DB based on login credentials
.
I tried with
$this->db->close();
and this->db->reconnect();
but it did not help
In your application/config/database.php you can define more than one database connection by doing
$db['database1']['hostname'] = 'localhost';
$db['database1']['username'] = 'db1_root';
$db['database1']['password'] = 'xxxxxx';
$db['database1']['database'] = 'database1_name';
$db['database1']['db_debug'] = false; //Important
$db['database2']['hostname'] = 'localhost';
$db['database2']['username'] = 'db2_root';
$db['database2']['password'] = 'xxxxxx';
$db['database2']['database'] = 'database2_name';
$db['database2']['db_debug'] = false; //Important
Then you can load specific databases by doing
$database1 = $this->load->database('database1', true);
$database2 = $this->load->database('database2', true);
Then rather than doing
$this->db->query();
You will need to do either
$database1->query();
$database2->query();
You can connect using a dynamic config in your controller/model/library/whatever by passing a config array to $this->load->database().
$config['hostname'] = "localhost";
$config['username'] = $user_name;
$config['password'] = $user_password;
$config['database'] = $user_database;
$config['dbdriver'] = "mysql";
$config['dbprefix'] = "";
$config['pconnect'] = FALSE;
$config['db_debug'] = TRUE;
$config['cache_on'] = FALSE;
$config['cachedir'] = "";
$config['char_set'] = "utf8";
$config['dbcollat'] = "utf8_general_ci";
$user_db = $this->load->database($config, true);
I figured out my answer.. Coded as follows:
in the database.php file i have added a new database config:
$db['db2']=$db['default'];
$db['db2']['database'] = 'new_db2';
and then in all the models constructor function i have put the following code:
$new_db = $this->load->database('db2', TRUE );
$this->db = $new_db;
So in this case i don't need to change all my queries. Hurray!!! :)
I have 2 queries which work fine:
var q = (from c in _context.Wxlogs
where (SqlFunctions.DatePart("Month", c.LogDate2) == m3) && (SqlFunctions.DatePart("Year", c.LogDate2) == y1)
group c by c.LogDate2
into g
orderby g.Key
let maxTemp = g.Max(c => c.Temp)
let minTemp = g.Min(c => c.Temp)
let maxHum = g.Max(c => c.Humidity)
let minHum = g.Min(c => c.Humidity)
select new
{
LogDate = g.Key,
MaxTemp = maxTemp,
MaxTempTime = g.FirstOrDefault(c => c.Temp == maxTemp).LogTime,
MinTemp = minTemp,
MinTempTime = g.FirstOrDefault(c => c.Temp == minTemp).LogTime,
MaxHum = maxHum,
MaxHumTime = g.FirstOrDefault(c => c.Humidity == maxHum).LogTime,
MinHum = minHum,
MinHumTime = g.FirstOrDefault(c => c.Humidity == minHum).LogTime,
});
var r = (from c in _context.Wxlogs
where
(SqlFunctions.DatePart("Month", c.LogDate2) == m3) &&
(SqlFunctions.DatePart("Year", c.LogDate2) == y1)
group c by c.LogDate2
into g
orderby g.Key
let maxDew = g.Max(c => c.Dew_Point)
let minDew = g.Min(c => c.Dew_Point)
//let maxWind = g.Max(c=> c.Wind_Gust)
let maxRainRate = g.Max(c => c.Rain_rate_now)
let maxPres = g.Max(c => c.Barometer)
let minPres = g.Min(c => c.Barometer)
select new
{
LogDate = g.Key,
MaxRainRateTime = g.FirstOrDefault(c => c.Rain_rate_now == maxRainRate).LogTime,
MaxPres = maxPres,
MaxPresTime = g.FirstOrDefault(c => c.Barometer == maxPres).LogTime,
MinPres = minPres,
MinPresTime = g.FirstOrDefault(c => c.Barometer == minPres).LogTime,
MinDew = minDew,
MinDewTime = g.FirstOrDefault(c => c.Dew_Point == minDew).LogTime,
MaxDew = maxDew,
MaxDewTime = g.FirstOrDefault(c => c.Dew_Point == maxDew).LogTime,
MaxRainRate = maxRainRate,
});
however when I try to combine them using union, in order to output the results to a WPF datgrid:
var result = r.Union(q);
the following error is thrown on the union:
Error 1 Instance argument: cannot convert from 'System.Linq.IQueryable<AnonymousType#1>' to 'System.Linq.ParallelQuery<AnonymousType#2>'
I can't seem to find a way to make this work and any help would be appreciated.
A "union" operation combines two sequences of the same type into a single set (i.e. eliminating all the duplicates). Since you clearly have sequences of two different types, you don't want a union operation. It looks like you want a "concat" operation, which just chains two sequences together. You need something like:
var result = r.Concat<object>(q);
However, since you're using L2E, your query will try to get executed on the server. Since your server won't allow you to combine your two queries (due to mismatched types), you need to execute them separately and then concat the sequences on the client:
var result = r.AsEnumerable().Concat<object>(q.AsEnumerable());
The use of AsEnumerable() runs the queries on the server and brings the results to the client.
Since it turns out that you want to combine the sequences next to each other (i.e. using the same rows in your grid but another group of columns), you actually want a join operation:
var result = from rrow in r.AsEnumerable()
join qrow in q.AsEnumerable() on rrow.LogDate equals qrow.LogDate
select new { rrow.LogDate,
rrow.MaxTemp, rrow.MaxTempTime,
rrow.MinTemp, rrow.MinTempTime,
rrow.MaxHum, rrow.MaxHumTime,
rrow.MinHum, rrow.MinHumTime,
qrow.MaxRainRate, qrow.MaxRainRateTime,
qrow.MaxPres, qrow.MaxPresTime,
qrow.MinPres, qrow.MinPresTime,
qrow.MaxDew, qrow.MaxDewTime,
qrow.MinDew, qrow.MinDewTime };
