I'm having trouble using implicit joins or Arrow joins "->". It's on an Intersystems Cache database. This is my code that isn't working
SELECT qcpr_arf_OC.AssessmentCategoryDataElement->AssessmentCategoryID
FROM qcpr_arf_OC.AssessmentCategory
I've read through Intersystems Implicit join page http://docs.intersystems.com/ens20102/csp/docbook/DocBook.UI.Page.cls?KEY=GSQL_specialfeatures
And I tried to alter this one to work as it's also a for the QCPR application Intersystems Cache coding query
So am I doing something wrong or am I assuming a parent/child relationship when there is none? If so how do I tell? Thank you to everyone for your time.
The syntax you are using is correct, but without database schema it's difficult to find an actual error.
What I would suggest, is to use "Query Builder" to create your first few queries in Cache. It's accessible from Management Protal -> Explore -> SQL, "Execute Query" tab, and there is a "Query Builder" button above text area. Don't forget to switch to your application namespace.

I was adding new Menu functions to Responsibility and then i updated wrong one. But not sure if it is updated now or it was there before.
So, I am searching for a query to find when a certain menu function is added to the certain responsibility.
Please help me.
If you have SQL query access, the who columns (audit columns) are a good place to start looking - check out the LAST_UPDATE_DATE for the date the modification was made and LAST_UPDATED_BY will tell you who updated the table. All the tables should have them. The tables involved are:
fnd_menu
fnd_menu_entry
fnd_nodes
fnd_user_resp_groups
fnd_resp_function
fnd_responsibility
I have an exam using SQLPlus and sometimes I don't remember the exact syntax of SQL statements, so I was wondering if there is any way to get some nice inline help from inside SQLPlus.
For instance, say I forgot how to use INSERT INTO, and I want some reminder like this:
INSERT INTO table-name (column-names)
VALUES (values)
Is this possible?
I tried HELP command but none of that seems to suits my needs.
I Googled it with no success.
No. SQL is a standardized language (at least ANSI SQL) and SQLPlus "just" uses that syntax, so it's not covered by internal help. Internal help lists only SQLPlus specific commands (ex. SET, CONNECT, SPOOL).
It is possible to workaround that in some way, but very limited. You can call dbms_metadata.get_ddl function for some existing object. Some of those DDLs could have statements you are intrested in. For example - you'd like to see select statement - then you could call dbms_metadata.get_ddl for some existing view:
select dbms_metadata.get_ddl('VIEW', 'USER_TABLES', 'SYS')
from dual;
Be aware - it works only for Oracle 11G and lower, in the newest one SYS objects are not accessible in that way (I'm not sure about Oracle 12.1).
The more interesting are tiggers, procedures, functions, and packages. You cannot use dbms_metadata to get DDLs of packages owned by SYS, but maybe you can connect to some sample schemas like HR (Human Resources), AD (Academic), SH (Sales History).
In HR schema there is stored procedure ADD_JOB_HISTORY, which has inside insert statement, so it looks like that:
select dbms_metadata.get_ddl('PROCEDURE', 'ADD_JOB_HISTORY')
from dual;
CREATE OR REPLACE EDITIONABLE PROCEDURE "HR"."ADD_JOB_HISTORY"
( p_emp_id job_history.employee_id%type
, p_start_date job_history.start_date%type
, p_end_date job_history.end_date%type
, p_job_id job_history.job_id%type
, p_department_id job_history.department_id%type
)
IS
BEGIN
INSERT INTO job_history (employee_id, start_date, end_date,
job_id, department_id)
VALUES(p_emp_id, p_start_date, p_end_date, p_job_id, p_department_id);
END add_job_history;
There are better ways and better tools to achieve your goal - see below.
Are you allowed to use SQL Developer instead of SQLPlus? SQL Developer has nice feature to drag-and-drop table icon into worksheet, then you will be nicely prompted to choose what kind of example statement you are looking for (SELECT, INSERT, UPDATE etc.) - after choosing one you will get sample statement.
But the best way is just open in browser Database SQL Language Reference:
https://docs.oracle.com/database/121/SQLRF/toc.htm
I want to execute multiple cypher queries at same time for the brower, how count i execute that. And i am using noe4j version for 2.2.5. My sample query was,
CREATE(n:Taxonomy{UUID:10001, name:"BOSH", classType:"Interface Type", version:"2.2",isDeleted:"0"});
CREATE(n:Taxonomy{UUID:10002, name:"Iaas", classType:"AWS", version:"0.0",isDeleted:"0"});
CREATE(n:Taxonomy{UUID:10003, name:"order lifecycle", classType:"draft order", version:"0.0",isDeleted:"0"});
CREATE(n:IaaSTemplate{UUID:20001, IaasName:"Iaas Template 1",isDeleted:"0"});
CREATE(n:TemplateFunction{UUID:30001, functionName:"bosh target",isDeleted:"0"});
CREATE(n:TemplateFunction{UUID:30002, functionName:"bosh login",isDeleted:"0"});
Batching multiple queries into one is not (yet) supported by the Browser.
However, the specific queries in your question can be easily combined into a single query by:
Removing the n identifier from all the nodes.
Within a single query, an identifier is associated with a specific instance of a node or relationship (ignoring the effect of WITH clauses). But, since you don't actually use the identifier, getting rid of it would allow all the CREATE clauses to co-exist in the same query.
Removing all semicolons (except the last one).
So, this should work:
CREATE(:Taxonomy{UUID:10001, name:"BOSH", classType:"Interface Type", version:"2.2",isDeleted:"0"})
CREATE(:Taxonomy{UUID:10002, name:"Iaas", classType:"AWS", version:"0.0",isDeleted:"0"})
CREATE(:Taxonomy{UUID:10003, name:"order lifecycle", classType:"draft order", version:"0.0",isDeleted:"0"})
CREATE(:IaaSTemplate{UUID:20001, IaasName:"Iaas Template 1",isDeleted:"0"})
CREATE(:TemplateFunction{UUID:30001, functionName:"bosh target",isDeleted:"0"})
CREATE(:TemplateFunction{UUID:30002, functionName:"bosh login",isDeleted:"0"});
Unfortunately Neo4j Browser doesn't support that yet, it's on the long list of things.
You can use the bin/neo4j-shell that connects to a running browser.
Or a project like cycli which is a colorful, auto-complete shell for Neo4j that talks to the http interface and supports auth etc.
I am trying to use Macros in FireDAC to Preprocess my SQL Queries. I have a TADQuery object on a Data Module with the SQL set to something like:
Select * from MyTable
join OtherTable on MyTable.Key = OtherTable.Key
&Where
Then in my code I do this:
WhereClause = 'stuff based on my form';
Query.MacroByName('Where').AsRaw := WhereClause;
Query.Open;
This has worked great for complicated queries because it lets me make sure my fields and join conditions are correct using the SQL Property editor.
My problem is when the SQL statements ends up invalid because of my where clause. Is there any way to see the SQL after pre-processing that is going to be executed? Right now I am catching the FireDac errors and showing the SQL that is on EADDBEngineException object. However that is still showing my original SQL with the macros. If I can't get to it after the error happens is there anyway to force the Macro replacement to take place so I can look at the SQL in the debugger to help me see what is wrong.
If it matters I am connecting to a MS Access database with the goal of moving to SQL Server in the near future.
Apart from using Text property, to monitor what SQL is actually going to the database engine, consider using the "FDMonitor" FireDAC utility. According to the DokWiki pages (below):
drop a TFDMoniRemoteClientLink component on your form,
Set its Tracing property to True,
Add the MonitorBy=Xxx connection definition parameter to your existing FDConnection component. You can do this in the IDE object inspector, by selecting your FDConnection component, expanding the Params property, and setting MonitorBy to mbRemote.
Note that the TFDMoniXxxxClientLink should come before TFDConnection in the data module or form creation order, so adjust this by right clicking on the form or data module, then Creation Order, and moving the TFDMoni.. component above the FDConnection.
Also, it's helpful in the options of the TFDMoniXxxxClientLink, to disable most of the events being recorded, otherwise all the data returned is also shown in the FireDAC monitor. Expand the EventKinds property, and turn all the event kinds off, except for perhaps ekConnConnect, ekConnPrepare, and ekCmdExecute.
Then open the FireDAC Monitor from the IDE, (Tools > FireDAC Monitor). Start your app only once the monitor is running. Double click on a trace event (in the Trace Output tab), and you will see the actual SQL sent to the database in the bottom pane.
It also seems likely that adding the EventType of ekConnPrepare as mentioned above, would show you when the query's Prepare is called, but I haven't played enough with it say for sure.
Please see the following pages on the DocWiki for more information:
Overview: FDMonitor
How to: Tracing and Monitoring (FireDAC)
Other FireDAC utilities: Utilities (FireDAC)
(Just to remove this question from list of unanswered questions)
From comments:
Well, I've roughly checked what's happening there and I'm still not
sure if calling Prepare (which is useless for you as I get) is the
minimal requirement to trigger that preprocessing. Though, the
preprocessed SQL, the one which is sent to the DBMS you can access
through the Text property (quite uncommon name for such property). – TLama Feb

What's the best way to do joins in Meteor/mongo? Use one of these packages, or something else:
publish-with-relations
https://github.com/erundook/meteor-publish-with-relations/blob/master/publish_with_relations.coffee
collection-helpers
https://github.com/dburles/meteor-collection-helpers
I'm very familiar with PWR, but collection-helpers is new to me. It looks like the two are complimentary.
PWR solves the somewhat complex problem of publishing documents to the client via a reactive join based on arbitrarily complex relationships. See this question for more details.
collection-helpers appears to be a set of convenience functions added to the client to be used when traversing collection relationships inside of a template (given that the required documents have already been published). For example, if you have books and authors in separate (but related) collections, you can immediately get myBook.author.fullName inside of a template without having to type out the extra find for the author.
currently the top popular solution in atmosphere seems to be publish-composite https://atmospherejs.com/reywood/publish-composite
