Would you please tell me how to assign a value to the variable on the Task? Here's the detailed scenario of what I'm trying to accomplish and what the error is.
To get the latest query_id of the below SQL statement, I am creating the following function.
CREATE OR REPLACE FUNCTION rejected_records_queryid()
RETURNS varchar
AS 'select query_id from snowflake.account_usage.query_history where QUERY_TEXT LIKE \'select 1, 2%\' AND EXECUTION_STATUS=\'SUCCESS\' order by START_TIME desc limit 1';
If I run this manually, the function works perfectly,
set qid = rejected_records_queryid();
Session variable value:
select $qid;
Please refer attached screenshot for the output.

However, if I use the Task, the return values of the function will not be assigned to the session variable,
CREATE OR REPLACE TASK rejected_records_queryid1
WAREHOUSE = COMPUTE_WH
SCHEDULE = '1 MINUTE'
AS
set qid2 = rejected_records_queryid();
Change the task mode to resume,
ALTER TASK rejected_records_queryid1 RESUME;
The following error message appears after I check the value of the qid2 after Task run,
SQL compilation error: error line 1 at position 7 Session variable '$QID2' does not exist
Attached screenshot for the error message In order to use it in the below sql, I need the qid2 value to be assigned from the Task,
select * from table(result_scan($qid2))

I would appreciate any help on how to assign the value to the variable in TASK or any other workarounds.
I am trying to get the values in "ID" column of DOORS and I am currently doing this
string ostr=richtext_identifier(o)
When I try to print ostr, in some modules I get just the ID(which is what I want). But in other modules I will get values like "{\rtf1\ansi\ansicpg1256\deff0\nouicompat{\fonttbl{\f0\fnil\fcharset0 Times New Roman;}{\f1\froman\fcharset0 Times New Roman;}} {*\generator Riched20 10.0.17134}\viewkind4\uc1 \pard\f0\fs20\lang1033 SS_\f1\fs24 100\par } " This is the RTF value and I am wondering what the best way is to strip this formatting and get just the value.
Perhaps there is another way to go about this that I am not thinking of as well. Any help would be appreciated.
So the ID column of DOORS is actually a composite- DOORS builds it out of the Module level attribute 'Prefix' and the Object level attribute 'Absolute Number'.
If you wish to grab this value in the future, I would do the following (using your variables)
string ostr = ( module ( o ) )."Prefix" o."Absolute Number" ""
This is opposed to the following, which (despite seeming to be a valid attribute in the insert column dialog) WILL NOT WORK.
string ostr = o."Object Identifier" ""
Hope this helps!
Comment response: You should not need the module name for the code to work. I tested the following successfully on DOORS 9.6.1.10:
Object o = current
string ostr = ( module ( o ) )."Prefix" o."Absolute Number" ""
print ostr
Another solution is to use the identifier function, which takes an Object as input parameter, and returns the identifier as a plain (not RTF) string:
Declaration
string identifier(Object o)
Operation
Returns the identifier, which is a combination of absolute number and module prefix, of object o as a string.
The optimal solution somewhat depends on your underlying requirement for retrieving the object ID.
my table:
db.define_table('problem',
Field('title','string',unique=True,length=255),
Field('description','text',notnull=False,default=''),
Field('in_date','datetime',notnull=False,default=request.now),
Field('input','text',notnull=False,default=''),
Field('result','text',notnull=False,default=''),
Field('defresult','text',notnull=False),
Field('submit','integer',notnull=False,default=0),
Field('solved','integer',notnull=False,default=0),
Field('pass_rate','decimal(2,2)',notnull=True,default =0.00),
format = '%(title)s')
Insert a record into problem table by sqlform,how to acquire the result field of problem in sqlform dynamically.
def test():
user_id=_get_user_id(auth)
id=request.args(0,cast=int)
for row in db(db.belongs.id==id).select():
taskid=row.task_id
problemid=row.problem_id
record=db.problem(problemid) or redirect(URL('index'))
fields=['title','description','input','result']
form=SQLFORM(db.problem,record,readonly=False,fields=fields)
if form.process().accepted:
db(db.problem.id==problemid).update(submit=db.problem.submit+1)
if(form.vars.result==db.problem.defresult):
The last line I want to judge if the result field is equal to the defresult field.
The form.vars.result seems not change even I input another value into sqlform and the values insert before have fill the sqlform after I reloading the page. how to clear the sqlform? Thanks!
form.vars.result does contain the new value. The problem is that in form.vars.result==db.problem.defresult, you are comparing that value to a Field object rather than to the actual value from the record. Earlier, you have:
record=db.problem(problemid)
So, your equality test should be:
if form.vars.result == record.defresult:
I simplified the code a little while trying to debug:
[HttpPost]
public ActionResult Register(User model)
{
DateTime bla = new DateTime(2012, 12, 12);
try
{
User user = new User
{
gid = 1,
cid = 1,
firstName = model.firstName,
lastName = model.lastName,
email = model.email,
username = model.username,
password = model.password,
creationDate = bla,
active = 1
};
myContext.Users.AddObject(user);
myContext.SaveChanges();
}
catch (Exception ex)
{
throw ex;
}
return View();
}
The values are transmited accordingly. Users table:
[id] [int] IDENTITY(1,1) NOT NULL,
[cid] [int] NULL,
[gid] [int] NULL,
[firstName] [nvarchar](100) NOT NULL,
[lastName] [nvarchar](100) NOT NULL,
[email] [nvarchar](max) NOT NULL,
[username] [nvarchar](100) NOT NULL,
[password] [nvarchar](100) NOT NULL,
[creationDate] [datetime] NOT NULL,
[active] [int] NOT NULL,
CONSTRAINT [PK_Users_3213E83F0AD2A005] PRIMARY KEY CLUSTERED
I deleted all the foreign keys to be sure that nothing affects it. I am qute certain that at a previous moment it was working, but now I can not figure where the issue is.
It crashes while performing the savechanges:
{"An error occurred while updating the entries. See the inner exception for details."}
{"The member with identity '' does not exist in the metadata collection.\r\nParameter name: identity"}
I had the same error being thrown when I try to insert using EF, the error was
The member with identity 'Id' does not exist in the metadata collection.\r\nParameter name: identity
It wasn't obvious at first but the exception message was very concise because my database knows the column Id int but the property created for the object on my code was int ID so coming back to named mapping, Id is not mapped to ID.
So when an object with property ID is sent to database that only know Id you will get the above error.
I hope this helps, thanks
The issue was reproducing because of a trigger that was on the users table. Removed it and the issue is not reproducing anymore.
There is probably a trigger on the table being updated and it returns output. The output is thrown away but it conflicts with EF. Such output is often used to debug triggers (and forgotten to delete later):
select 'trigger called, i am here'
or there can be missing variable:
select column
instead of
select #variable=column
I think that the best solution is in this post. I used the 3rd option and works.
Here I report the reply in the link:
The issue could be related to a "instead of insert" trigger on one of
your tables.
The EF framework is performing validation on the inserted row of data
by calling scope_identity(). However, an "instead of insert" trigger
will change the context of the insertion in such a way that the EF
system's call to scope_identity will return null.
A couple ways around this:
Use a stored procedure to insert the data ( not tested )
Remove the instead of insert trigger ( triggers can cause other problems, so some people argue not to use them) ( tested, works!)
Turn off validation in the EF framework, so: context.Configuration.ValidateOnSaveEnabled = false ( tested, works!)
I had this same error today and spent a few frustrating hours trying to figure it out.
I was using Entity Framework to insert a record with an identity column into a SQL server database table. Simple enough.
The table had a trigger on it which in turn ran a stored procedure. The stored procedure had a line in it:
select newid()
This is the line that broke Entity Framework.
For tables with identity columns, Entity Framework expects to be returned a single row with a single field that is the identity column.
it's because of trigger pass back value to EF
if you are using trigger. in my problem i must check a value by selecting from other table and using of 'select' cause error in EF, so you must replace 'select' with 'set'.
you can not use this code.
select #any= any from tablename
you should use set instead of select
set #any= (select any from tablename)
Somedays, I hate M$.
The member with identity 'ChangeID' does not exist in the metadata collection.
Parameter name: identity
I've spent two days trying to get around this.
I'm using MVC.
To get all the data I need in one fell swoop, I created a view of the table in the DB for this application, and tables in other databases. (You may update views, with some constraints.)
I do a get, and all my data is present in the record, keys, descriptions, foreign keys, etc.
I created triggers on my view, to update the portion of the view that came from the local table.
Instead of Delete worked fine.
Instead of Update worked fine.
This error kept raising it's head on Instead of Insert. I could NOT get the insert trigger to successfully insert into my table. If I ran an insert on the view, with all fields provided in the SQL Management Studio, it worked fine. I know the exact values being passed because I ran SQL Server Profiler to see the code being passed.
But when the app attempted the update, it failed with The member with identity 'ChangeID' does not exist in the metadata collection.
Clue up above, someone said, "MVC expects table key to be ID"
I renamed ChangeID as ID in my view, changed it in the App, and BAM! Now it works.
What did NOT work:
db.Configuration.ValidateOnSaveEnabled = false;
adding a select to the trigger to get scope identity
Why do I have to modify my DB or my view to satisfy some hidden M$ assumption?
None the less, after two very frustrating days, code is now working. Maybe this will save someone else some time as well.
Try this
[HttpPost]
public ActionResult Register(User model)
{
DateTime bla = new DateTime(2012, 12, 12);
try
{
model.gid = 1;
model.cid = 1;
model.creationDate = bla;
model.active = 1;
myContext.Users.AddObject(model);
myContext.SaveChanges();
}
catch (Exception ex)
{
Console.WriteLine(ex);
throw;
}
return View();
}
I was having this issue and my fix, was that in my connection-string metadata I did not specify my model in the .msl format.
See more info here
In my case, SetName of the entity was incorrect. Shortly, this worked for me:
Use
myContext.AddObject(nameOfSetEntity, user);
Instead of:
myContext.Users.AddObject(user);
To get the whole correct name of the entity (thanks to Nix's answer)
string className = typeof(User).Name;
var container = myContext.MetadataWorkspace.GetEntityContainer(myContext.DefaultContainerName, System.Data.Metadata.Edm.DataSpace.CSpace);
string nameOfSetEntity= (from meta in container.BaseEntitySets
where meta.ElementType.Name == className
select meta.Name).First();
Context.AddObject(nameOfSetEntity, user);
I have a stored proc on an existing 3rd party application (SQL 2005) that I wish to interact with.
It is an insert statement followed by a select statement as follows;
Set #CustomerId = Cast(SCOPE_IDENTITY() As [int])
Select #CustomerId
Using VB6 how do I access the value of #CustomerID?
set rs = cmd.Execute
is not returning a resultset as expected...
[Edit]
rs.Fields.Count is 0.
Any attempt to access the resulting recordset, like rs(0).Value simply causes an "Item not found..." error.
I would guess that your stored procedure is returning more than one recordset.
If this is the case, you can use the NextRecordset() method to iterate through them.
MSDN:
If a row-returning command executes successfully but returns no records,
the returned Recordset object will be
open but empty. Test for this case by
verifying that the BOF and EOF
properties are both True.
If a non–row-returning command executes successfully, the returned
Recordset object will be closed, which
you can verify by testing the State
property on the Recordset.
When there are no more results, recordset will be set to Nothing.
This means I would suggest something like this to solve your problem:
Set rs = cmd.Execute
''# fetch the first value of the last recordset
Do Until rs Is Nothing
If rs.State = adStateOpen Then
If Not (rs.BOF And rs.EOF) Then
''# You can do a different sanity check here, or none at all
If rs.Fields(0).Type = adInteger Then
CustomerId = rs.Fields(0).Value
End If
End If
End If
Set rs = rs.NextRecordSet
Loop
MsgBox CustomerId
