Orientdb sql auto increment: id is always null (sql batch, update increment, variables) - sql

I was looking at another question in stackoverflow regarding auto increment fields in orientdb, where one of the answers was to create our own vertex with counter field.
However, when I'm trying to execute the following code (both java api and console script batch), It is not working.
Do note however that the id is returned good (did some debug attempts, returning the id variable only), and the vertex is created.
However, the vertex id is always null (unless I set it explicit, that is).
The script:
script sql
LET id = UPDATE CCounter INCREMENT value=1 RETURN AFTER $current WHERE name='session'
LET csession = CREATE VERTEX CDate SET id=$id.result, meet_date='2015-01-01 15:23:00'
end
I tried playing around with $id and $current , but nothing seems to work.
Currently I am doing it in a 2-transaction mode; one to get the id, and another to create the vertex. I really hope there is a better way though.
P.S.
I am using version 2.0-M2

You should execute
LET csession = CREATE VERTEX CDate SET id=$id.value, meet_date='2015-01-01 15:23:00'
Note the $id.value in place of $id.result.

As stated in a comment to Lvca, the answer was:
(1) Change the field name. Id seems to be reserved (ish). It's probably possible to still bypass it and use a field named 'id', but I didn't want to mess around with it.
(2) From some reason, the result was a collection (shown as '[id]'). It took me some time to figure it out, but I just had to choose the first value from it.
(3) Also, there are 2 'values' here. One of the field ($current.value), and the second one(not sure where it's coming from).
Final solution that works:
script sql
LET id = UPDATE CCounter INCREMENT value = 1 RETURN AFTER $current.value WHERE name='session'
LET csession = CREATE VERTEX CDate SET data_id=$id[0].value, meet_date='2015-01-01 15:23:00'
end

Is there a more efficient way to return all records in a "traversed" link'ed list?

I have a generic (non-V) class with a LINKMAP field that links a chain of time-series data. Each record links to the next record based on a key of the next month/day/hour/etc. and a value of the #rid of the next record. I could use edges (non-lightweight, with a single property the same as the LINKMAP key), but I don't want to because I only need a one-direction link and want to use the least amount of storage space (plus my assumption is that while using edges might offer slightly easier querying, it wouldn't offer any benefit in terms of performance or storage space).
I currently have the following batch query:
begin;
let r = select from data where key='AAA';
let y = select expand(links['2017']) from $r;
let m = select expand(links['07']) from $y;
let d = select expand(links['15']) from $m;
let h = select expand(links['10']) from $d;
return (select $r[0], $y[0], $m[0], $d[0], $h[0])
This works, in the sense that I get a result set with the #rids of each record in the link'ed list.
I have two questions:
Is there a more efficient way to do this query? I've tried various TRAVERSE options with $path and such, but nothing else I attempted worked at all. I did not try MATCH because I'm not using edges.
The current result set is flat, with each value prop ($r, $y, etc.) containing the corresponding #rid. That's OK for my purposes, but I'd like to know if there's a way to return the actual records instead of just the #rids. Nothing I've tried works.
PS - I'm using orientjs, but the batch runs identically from the console as well.

Zoho Creator making a custom function for a report

Trying to wrap my head around zoho creator, its not as simple as they make it out to be for building apps… I have an inventory database, and i have four fields that I call to fill a field called Inventory Number (Inv_Num1) –
First Name (First_Name)
Last Name (Last_Name)
Year (Year)
Number (Number)
I have a Custom Function script that I call through a Custom Action in the form report. What I am trying to do is upload a CSV file with 900 entries. Of course, not all of those have those values (first/last/number) so I need to bulk edit all of them. However when I do the bulk edit, the Inv_Num1 field is not updated with the new values. I use the custom action to populate the Inv_Num1 field with the values of the other 4 fields.
Heres is my script:
void onetime.UpdateInv()
{
for each Inventory_Record in Management
{
FN = Inventory_Record.First_Name.subString(0,1);
LN = Inventory_Record.Last_Name.subString(0,1);
YR = Inventory_Record.Year.subString(2,4);
NO = Inventory_Record.Number;
outputstr = FN + LN + YR + NO;
Inventory_Record.Inv_Num1 = outputstr;
}
}
I get this error back when I try to run this function
Error.
Error in executing UpdateInv workflow.
Error in executing For Each Record task.
Error in executing Set Variable task. Unable to update template variable FN.
Error evaluating STRING expression :
Even though there is a First Name for example, it still thinks there is none. This only happens on the fields I changed with Bulk Edit. If I do each one by hand, then the custom action works—but of course then the Inv_Num1 is already updated through my edit on success functions and makes the whole thing moot.
this may be one year late, you might have found the solution but just to highlight, the error u were facing was just due to the null value in first name.
you just have put a null check on each field and u r good to go.
you can generate the inv_number on the time of bulk uploading also by adding null check in the same code on and placing the code on Add> On Submt.( just the part inside the loop )
the Better option would be using a formula field, you just have to put this formula in that formula field and you'll get your inventory_number autogenerated , you can rename the formula_field to Inv Number or whaterver u want.
Since you are using substring directly in year Field, I am assuming the
year field as string.else you would have to user Year.tostring().substring(2,4) & instead of if(Year=="","",...) you have to put if(Year==null , null,...);
so here's the formula
if(First_Name=="","",First_Name.subString(0,1))+if(Last_Name =="","",Last_Name.subString(0,1)) + if(Year=="","",Year.subString(2,4)+Number
Let me know ur response if u implement this.
Without knowing the datatype its difficult to fix, but making the assumption that your Inventory_Record.number is a numeric data item you are adding a string to a number:
The "+" is used for string Concatenation - Joiner but it also adds two numbers together so think "a" + "b" = "ab" for strings but for numbers 1 + 2 = 3.
All good, but when you do "a" + 2 the system doesn't know whether to add or concatenate so gives an error.

Neo4J create temp variable within Cypher

So my Top-Level problem is I am trying to return whether a MERGE resulted in the creation of a new Node or not.
In order to do this I was thinking I could just create a simple temp boolean setting it to TRUE using ON CREATE
How I imagine it working:
MERGE(: Person {id:'Tom Jones'})
WITH false as temp_bool
ON CREATE set temp_bool = true
RETURN temp_bool
Obviously this does not work.
I am looking for a way to create arbitrary temp values within a Cypher query, and have the ability to return those variables in the end.
Thanks
You can do what you want, here's how (combination of my first answer, with #cybersam's addition). You just do it with a node property you create and then remove, instead of an unbound variable as you've been trying.
MERGE(tom:Person {id:'Tom Jones'})
ON CREATE set tom.temp_bool = true
ON MATCH set tom.temp_bool = false
WITH tom, tom.temp_bool AS result
REMOVE tom.temp_bool
RETURN result;
In simple merging cases like this where maximum one node could be created, a cleaner way to achieve what you are looking for could be checking the result stats. I case of using Bolt API you should check:
results.consume().counters.nodes_created = 1

Magento Bulk update attributes

I am missing the SQL out of this to Bulk update attributes by SKU/UPC.
Running EE1.10 FYI
I have all the rest of the code working but I"m not sure the who/what/why of
actually updating our attributes, and haven't been able to find them, my logic
is
Open a CSV and grab all skus and associated attrib into a 2d array
Parse the SKU into an entity_id
Take the entity_id and the attribute and run updates until finished
Take the rest of the day of since its Friday
Here's my (almost finished) code, I would GREATLY appreciate some help.
/**
* FUNCTION: updateAttrib
*
* REQS: $db_magento
* Session resource
*
* REQS: entity_id
* Product entity value
*
* REQS: $attrib
* Attribute to alter
*
*/
See my response for working production code. Hope this helps someone in the Magento community.
While this may technically work, the code you have written is just about the last way you should do this.
In Magento, you really should be using the models provided by the code and not write database queries on your own.
In your case, if you need to update attributes for 1 or many products, there is a way for you to do that very quickly (and pretty safely).
If you look in: /app/code/core/Mage/Adminhtml/controllers/Catalog/Product/Action/AttributeController.php you will find that this controller is dedicated to updating multiple products quickly.
If you look in the saveAction() function you will find the following line of code:
Mage::getSingleton('catalog/product_action')
->updateAttributes($this->_getHelper()->getProductIds(), $attributesData, $storeId);
This code is responsible for updating all the product IDs you want, only the changed attributes for any single store at a time.
The first parameter is basically an array of Product IDs. If you only want to update a single product, just put it in an array.
The second parameter is an array that contains the attributes you want to update for the given products. For example if you wanted to update price to $10 and weight to 5, you would pass the following array:
array('price' => 10.00, 'weight' => 5)
Then finally, the third and final attribute is the store ID you want these updates to happen to. Most likely this number will either be 1 or 0.
I would play around with this function call and use this instead of writing and maintaining your own database queries.
General Update Query will be like:
UPDATE
catalog_product_entity_[backend_type] cpex
SET
cpex.value = ?
WHERE cpex.attribute_id = ?
AND cpex.entity_id = ?
In order to find the [backend_type] associated with the attribute:
SELECT
  backend_type
FROM
  eav_attribute
WHERE entity_type_id =
  (SELECT
    entity_type_id
  FROM
    eav_entity_type
  WHERE entity_type_code = 'catalog_product')
AND attribute_id = ?

Hope this helps you.

MOSS 2007: What is the source of "Directories"?

I'm trying to generate a new SharePoint list item directly using SQL server. What's stopping me is damn tp_DirName column. I have no ideas how to create this value.
Just for instance, I have selected all tasks from AllUserData, and there are possible values for the column: 'MySite/Lists/Task', 'Lists/Task' and even 'MySite/Lists/List2'.
MySite is the FullUrl value from Webs table. I can obtain it. But what about 'Lists/Task' and '/Lists/List2'? Where they are stored?
If try to avoid SQL context, I can formulate it the following way: what is the object, that has such attribute as '/Lists/List2'? Where can I set it up in GUI?
Just a FYI. It is VERY not supported to try and write directly to SharePoint's SQL Tables. You should really try and write something that utilizes the SharePoint Object Model. Writing to the SharePoint database directly mean Microsoft will not support the environment.
I've discovered, that [AllDocs] table, in contrast to its title, contains information about "directories", that can be used to generate tp_DirName. At least, I've found "List2" and "Task" entries in [AllDocs].[tp_Leaf] column.
So the solution looks like this -- concatenate the following 2 components to get tp_DirName:
[Webs].[FullUrl] for the web, containing list, containing item.
[AllDocs].[tp_Leaf] for the list, containing item.
Concatenate the following 2 components to get tp_Leaf for an item:
(Item count in the list) + 1
'_.000'
Regards,
Well, my previous answer was not very useful, though it had a key to the magic. Now I have a really useful one.
Whatever they said, M$ is very liberal to the MOSS DB hackers. At least they provide the following documents:
http://msdn.microsoft.com/en-us/library/dd304112(PROT.13).aspx
http://msdn.microsoft.com/en-us/library/dd358577(v=PROT.13).aspx
Read? Then, you know that all folders are listed in the [AllDocs] table with '1' in the 'Type' column.
Now, let's look at 'tp_RootFolder' column in AllLists. It looks like a folder id, doesn't it? So, just SELECT the single row from the [AllDocs], where Id = tp_RootFolder and Type = 1. Then, concatenate DirName + LeafName, and you will know, what the 'tp_DirName' value for a newly generated item in the list should be. That looks like a solid rock solution.
Now about tp_LeafName for the new items. Before, I wrote that the answer is (Item count in the list) + 1 + '_.000', that corresponds to the following query:
DECLARE #itemscount int;
SELECT #itemscount = COUNT(*) FROM [dbo].[AllUserData] WHERE [tp_ListId] = '...my list id...';
INSERT INTO [AllUserData] (tp_LeafName, ...) VALUES(CAST(#itemscount + 1 AS NVARCHAR(255)) + '_.000', ...)
Thus, I have to say I'm not sure that it works always. For items - yes, but for docs... I'll inquire into the question. Leave a comment if you want to read a report.
Hehe, there is a stored procedure named proc_AddListItem. I was almost right. MS people do the same, but instead of (count + 1) they use just... tp_ID :)
Anyway, now I know THE SINGLE RIGHT answer: I have to call proc_AddListItem.
UPDATE: Don't forget to present the data from the [AllUserData] table as a new item in [AllDocs] (just insert id and leafname, see how SP does it itself).
