I am trying to show last4 of the CC and the Card type in a report, by going through the Database I have learned that inside sales_flat_quote_payment there is a field called additional information, and that field seems to have all the info I need, so I would need to extract if out of there. but the issue is that I am trying to find a way to join the sales_flat_quote_payment with sales_flat order tables so I can match the records by increment_id, but can't seem to find a way to do this.
I already tried:
orders->getSelect()->join(
array('p' => $orders->getResource()->getTable('sales/order_payment')),
'p.parent_id = main_table.entity_id',
array('cc_last4' => 'p.cc_last4', 'cc_type' => 'p.cc_type')
);
'OrderCreditCardLast4' => $order['cc_last4'],
but with no luck.
assuming you have the order number, do this:
select a.reserved_order_id, b.cc_last4
from sales_flat_quote a, sales_flat_quote_payment b
where b.quote_id=a.entity_id and a.reserved_order_id='YOUR ORDER NUMBER HERE';

This is a textual description of data for which I need to create a database design (using SQLite) for an application.
The application needs to keep a record of operations. Each operation has a Name and its list of parameters. Each parameter has its Name and a Value. However, the values of the parameters will change over the lifetime of the app (in fact the user will be able to changes them using GUI) and we want to keep a history of the values which a certain parameter has had. Furthermore, each operation can have multiple parameter sets. A parameter set is like an envelope which encompasses a set of parameter values (which all belong to the same operation) and gives this envelope a unique Number and a non-unique Description.
This is what I have so-far:
[Database model image][1]
The database model should allow me to perform these actions on the database data:
Show a list of operations - I know how to do this.
Show a list of parameters for a given operation - I know how to do this.
For a given operation, show all its parameters as columns and show the values of the parameters as rows - each row represents a different parameter value from the history of values. I'm stuck at this one.
For a given operation, show a list of all parameter sets which belong to that operation. I'm stuck at this one too.
For a given operation and for a given parameter set, get the latest values of its parameters. Stuck at this.
I'm not sure if I should re-work my database model or if I should look for proper SQL statements to accomplish the tasks above with the model that I have. Any help is greatly appreciated. Thank you.
EDIT 1
I have re-worked my database model according to a helpful advice from #Marek Herman. Thanks to that I am able to accomplish tasks 1) 2) 4).
Now I'm trying to accomplish 5) which should not be that difficult with the current database model. I have this SQL statement:
SELECT Parameter.ParameterIdentifier, ParameterValue.ParameterValue,
ParameterValueVersion.VersionNumber, ParameterValueVersion.ChangedOn
FROM ParameterValueVersion INNER JOIN
(((Operation INNER JOIN Parameter ON Operation.OperationPLC_ID = Parameter.OperationPLC_ID)
INNER JOIN ParameterSet ON Operation.OperationPLC_ID = ParameterSet.OperationPLC_ID)
INNER JOIN ParameterValue ON (ParameterSet.ID = ParameterValue.ParameterSetID) AND
(Parameter.ID = ParameterValue.ParameterID)) ON ParameterValueVersion.ID = ParameterValue.ParameterValueVersionID
WHERE (Operation.OperationPLC_ID=[opID] AND
ParameterSet.ParameterSetNumber=[parSetNum]);
where [opID] and [parSetNum] are the input parameters. This SQL statement actually only joins all these tables together on their PK->FK relationship: Operation, Parameter, ParameterSet, ParameterValue, ParameterValueVersion and filters the rows by specified OperationPLC_ID and ParameterSetNumber.
Here is an example of an output of this SQL statement. Each row shows a name of a parameter, its value, a version number of the value and date of change of that value. Some parameters only have one value (only one version -e.g., "OFFSET"). Some parameters have two values. For example "PREFILLING" has a value of "3" which was input on Oct 20, 2016 (and has a version number 1) and it also has a value of "3.5" which was input on Oct 21, 2016 and has a version number of 2. So I'd like to show only the latest versions of the values of the parameters. Any advice how to modify the SQL statement is much appreciated. Thank you.
EDIT 2
I guess I figured out how to perform 5). I had to study a bit how GROUP BY works. This did the trick:
SELECT Parameter.ParameterIdentifier, last(ParameterValue.ParameterValue) AS ParameterValue, last(ParameterValueVersion.ChangedOn) AS ChangedOn, max(ParameterValueVersion.VersionNumber) AS VersionNumber
FROM ParameterValueVersion INNER JOIN
(((Operation INNER JOIN Parameter ON Operation.OperationPLC_ID = Parameter.OperationPLC_ID)
INNER JOIN ParameterSet ON Operation.OperationPLC_ID = ParameterSet.OperationPLC_ID)
INNER JOIN ParameterValue ON (ParameterSet.ID = ParameterValue.ParameterSetID) AND
(Parameter.ID = ParameterValue.ParameterID)) ON ParameterValueVersion.ID = ParameterValue.ParameterValueVersionID
WHERE (((Operation.OperationPLC_ID)=[opID]) AND ((ParameterSet.ParameterSetNumber)=[parSetNum]))
GROUP BY Parameter.ParameterIdentifier
ORDER BY Parameter.ParameterIdentifier
Now I still need to figure out how to perform task no. 3. I'm gonna study the suggested COALESCE function. Thank you.
0) I would connect ParameterSet to Operation and Parameter and not to ParameterValue.
1) okay!
2) okay!
3) I think you can use the COALESCE() function to display the columns and then it should be possible to show all parameters with matching OperationID
4) you can do that if you do point #0
5) same as above I think
I have some images stored in the default cluster in my OrientDB database. I stored them by implementing the code given by the documentation in the case of the use of multiple ORecordByte (for large content): http://orientdb.com/docs/2.1/Binary-Data.html
So, I have two types of object in my default cluster. Binary datas and ODocument whose field 'data' lists to the different record of binary datas.
Some of the ODocument records' RID are used in some other classes. But, the other records are orphanized and I would like to be able to retrieve them.
My idea was to use
select from cluster:default where #rid not in (select myField from MyClass)
But the problem is that I retrieve the other binary datas and I just want the record with the field 'data'.
In addition, I prefer to have a prettier request because I don't think the "not in" clause is really something that should be encouraged. Is there something like a JOIN which return records that are not joined to anything?
Can you help me please?
To resolve my problem, I did like that. However, I don't know if it is the right way (the more optimized one) to do it:
I used the following SQL request:
SELECT rid FROM (FIND REFERENCES (SELECT FROM CLUSTER:default)) WHERE referredBy = []
In Java, I execute it with the use of the couple OCommandSQL/OCommandRequest and I retrieve an OrientDynaElementIterable. I just iterate on this last one to retrieve an OrientVertex, contained in another OrientVertex, from where I retrieve the RID of the orpan.
Now, here is some code if it can help someone, assuming that you have an OrientGraphNoTx or an OrientGraph for the 'graph' variable :)
String cmd = "SELECT rid FROM (FIND REFERENCES (SELECT FROM CLUSTER:default)) WHERE referredBy = []";
List<String> orphanedRid = new ArrayList<String>();
OCommandRequest request = graph.command(new OCommandSQL(cmd));
OrientDynaElementIterable objects = request.execute();
Iterator<Object> iterator = objects.iterator();
while (iterator.hasNext()) {
OrientVertex obj = (OrientVertex) iterator.next();
OrientVertex orphan = obj.getProperty("rid");
orphanedRid.add(orphan.getIdentity().toString());
}
I have a Table A related many to many with a Table B and I want to know how many related rows I have in B with a given A entity.
In SQL it would be something like this:
SELECT COUNT(*) FROM AB WHERE A_id=1;
I thought that I should place it in the model of A with a Virtual Field that retrieves the count, but I didn´t find a way to use the model itself to get the related B rows.
I tried with
$this->contain(['B'])->count()
But it didn't work because 'contain' is undefined. So, how should I get the count?
Make sure that u put the association in both of your models initialize method and dont call contain() on $this.
$query = $this->A->find();
numberOfRecords = $query->contain(['B'])->count;
I have a basic "property bag" table that stores attributes about my primary table "Card." So when I want to start doing some advanced searching for cards, I can do something like this:
SELECT dbo.Card.Id, dbo.Card.Name
FROM dbo.Card
INNER JOIN dbo.CardProperty ON dbo.CardProperty.IdCrd = dbo.Card.Id
WHERE dbo.CardProperty.IdPrp = 3 AND dbo.CardProperty.Value = 'Fiend'
INTERSECT
SELECT dbo.Card.Id, dbo.Card.Name
FROM dbo.Card
INNER JOIN dbo.CardProperty ON dbo.CardProperty.IdCrd = dbo.Card.Id
WHERE (dbo.CardProperty.IdPrp = 10 AND (dbo.CardProperty.Value = 'Wind' OR dbo.CardProperty.Value = 'Fire'))
What I need to do is to extract this idea into some kind of stored procedure, so that ideally I can pass in a list of property/value combinations and get the results of the search.
Initially this is going to be a "strict" search meaning that the results must match all elements in the query, but I'd also like to have a "loose" query so that it would match any of the results in the query.
I can't quite seem to wrap my head around this one. My previous version of this was to do generate some massive SQL query to execute with a lot of AND/OR clauses in it, but I'm hoping to do something a little more elegant this time. How do I go about doing this?
it seems to me that you have an EAV model here.
if you're using sql server 2005 and up i'd suggest you use XML datatype for this:
http://weblogs.sqlteam.com/mladenp/archive/2006/10/14/14032.aspx
makes searching and stuff much easier with built in xml querying capabilities.
if you can't change your model then look at this:

I have a n...n structure for two tables, makes and models. So far no problem.
In a third table (products) like:
id
make_id
model_id
...
My problem is creating a view for products of one specifi make inside my ProductsController containing just that's make models:
I thought this could work:
var $uses = array('Make', 'Model');
$this->Make->id = 5; // My Make
$this->Make->find(); // Returns only the make I want with it's Models (HABTM)
$this->Model->find('list'); // Returns ALL models
$this->Make->Model->find('list'); // Returns ALL models
So, If I want to use the list to pass to my view to create radio buttons I will have to do a foreach() in my make array to find all models titles and create a new array and send to the view via $this->set().
$makeArray = $this->Make->find();
foreach ($makeArray['Model'] as $model) {
$modelList[] = $model['title'];
}
$this->set('models', $models)
Is there any easier way to get that list without stressing the make Array. It will be a commom task to develops such scenarios in my application(s).
Thanks in advance for any hint!
Here's my hint: Try getting your query written in regular SQL before trying to reconstruct using the Cake library. In essence you're doing a lot of extra work that the DB can do for you.
Your approach (just for show - not good SQL):
SELECT * FROM makes, models, products WHERE make_id = 5
You're not taking into consideration the relationships (unless Cake auto-magically understands the relationships of the tables)
You're probably looking for something that joins these things together:
SELECT models.title FROM models
INNER JOIN products
ON products.model_id = models.model_id
AND products.make_id = 5
Hopefully this is a nudge in the right direction?
Judging from your comment, what you're asking for is how to get results from a certain model, where the condition is in a HABTM related model. I.e. something you'd usually do with a JOIN statement in raw SQL.
Currently that's one of the few weak points of Cake. There are different strategies to deal with that.
Have the related model B return all ids of possible candidates for Model A, then do a second query on Model A. I.e.:
$this->ModelB->find('first', array('conditions' => array('field' => $condition)));
array(
['ModelB'] => array( ... ),
['ModelA'] => array(
[0] => array(
'id' => 1
)
)
Now you have an array of all ids of ModelA that belong to ModelB that matches your conditions, which you can easily extract using Set::extract(). Basically the equivalent of SELECT model_a.id FROM model_b JOIN model_a WHERE model_b.field = xxx. Next you look for ModelA:
$this->ModelA->find('all', array('conditions' => array('id' => $model_a_ids)));
That will produce SELECT model_a.* FROM model_a WHERE id IN (1, 2, 3), which is a roundabout way of doing the JOIN statement. If you need conditions on more than one related model, repeat until you have all the ids for ModelA, SQL will use the intersection of all ids (WHERE id IN (1, 2, 3) AND id IN (3, 4, 5)).
If you only need one condition on ModelB but want to retrieve ModelA, just search for ModelB. Cake will automatically retrieve related ModelAs for you (see above). You might need to Set::extract() them again, but that might already be sufficient.
You can use the above method and combine it with the Containable behaviour to get more control over the results.
If all else fails or the above methods simply produce too much overhead, you can still write your own raw SQL with $this->Model->query(). If you stick to the Cake SQL standards (naming tables correctly with FROM model_as AS ModelA) Cake will still post-process your results correctly.
Hope this sends you in the right direction.
All your different Make->find() and Model->find() calls are completely independent of each other. Even Make->Model->find() is the same as Model->find(), Cake does not in any way remember or take into account what you have already found in other models. What you're looking for is something like:
$this->Product->find('all', array('conditions' => array('make_id' => 5)));
Check out the Set::extract() method for getting a list of model titles from the results of $this->Make->find()
The solution can be achieved with the use of the with operation in habtm array on the model.
Using with you can define the "middle" table like:
$habtm = " ...
'with' => 'MakeModel',
... ";
And internally, in the Model or Controller, you can issue conditions to the find method.
