Using Symfony with Sql Server and from what I've read, it seems that the connection to the database is not stable.
As soon as I use the orderBy method I get an error :
Here's an example :
$qStores =
$this->getManager()
->createQueryBuilder()
->select('rpdv')
->from('MainBundle:PointDeVenteReference', 'rpdv')
->andWhere( 'rpdv.partenaireClient = :id_partner ' )
->setParameter( 'id_partner', $this->getUser()->getPartenaire()->getIdPartenaire() )
->orderBy( 'rpdv.idPointDeVenteReference' , 'DESC' )
->setFirstResult( 0 )
->setMaxResults( 30 );
$stores = new Paginator( $qStores, FALSE );
And the error :
An exception has been thrown during the rendering of a template ("An exception occurred while executing
'SELECT DISTINCT TOP 30 id_point_de_vente_reference0
FROM ( SELECT p0_.id_point_de_vente_reference AS id_point_de_vente_reference0,
p0_.reference AS reference1,
p0_.date_derniere_modification AS date_derniere_modification2,
p0_.blocage AS blocage3
FROM point_de_vente_reference p0_
WHERE p0_.id_partenaire_client = ?

The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions,
unless TOP, OFFSET or FOR XML is also specified.") in MainBundle:Default:store/list.html.twig at line 79.
I tried to change the class SQLServerPlatform with corrections found on the net, without success.
Do you have any idea?
Thx !
Edit :
This bug appears to be related to the Paginator with the second parameter to true. Passing it to false, I have no error
The dctrn_result is a derived table. From the error message, you can not use an order by. I do not know symfony2, but the code going to the database engine is invalid.

I work with large databases that needs to be stored into a server.
So, to work with them on Rstudio I have to open a connection to my Microsoft SQL Server with the dbConnect function :
conn <- dbConnect(odbc(),"myconnection",uid="***",pwd="***",schema="dbo",access="readonly")
and in order to use dplyr, I have to create data references with the tbl function :
data <- tbl(conn, "data")
But one of the online dataframe contains a columns that I can't read because I dont have the access, but I can read everything else.
The SQL query behind the tbl() function is :
SELECT * FROM data
and this is my problem.
Even when I try to select a specific column it doesn't work (see below), so I can't create my references and I can't work.
select(tbl(conn, "data"), "columnX")
=
SELECT columnX FROM data
I think this is the tbl() function and the call of "SELECT *" that blocks me.
Do you know what can I do ? Is there smilar functions that could resolve my problem ?
If you know the columns that you have access to, then one option is to bypass the default access SELECT * FROM ... with your own SQL query.
A remote table is defined by two components:
The database conneciton
The query to the database
When you connect with the default approach tbl(conn, 'data') then it defaults to a query SELECT * FROM data.
But here is another approach:
custom_query = 'SELECT columnX FROM data'
remote_table = tbl(conn, dbplyr::sql(customer_query))
I'm using SQL Server within my Laravel application. I need to group/sum a table for the month/year. My query looks like this:
$positions = BelegPos::select(
DB::raw("YEAR(Datum) as year"),
DB::raw("MONTH(Datum) as month"),
DB::raw("SUM(Menge) as stunden")
)->groupBy("year", "month")
->get();
I'll get the following error message:
SQLSTATE[42S22]: [Microsoft][ODBC Driver 17 for SQL Server][SQL
Server]Invalid column name 'year'.
I don't know what's wrong, as the query the way I build it works fine with MySQL servers.
Thanks for any hint in the right direction.
UPDATE
I researched a bit more and read about somthing that points out, that the Select Statement isn't available in the GROUP BY section and that you have to add the same query there. so my query looks now like this:
$positions = selectlineBelegPos::select(
DB::raw("YEAR(Datum) as the_year"),
DB::raw("MONTH(Datum) as the_month"),
DB::raw("SUM(Menge) as stunden")
)
->groupBy(DB::raw("YEAR(Datum) as the_year"),DB::raw("MONTH(Datum) as the_month"))
->get();
Still not the solution but the error message has changed to this:
SQLSTATE[42000]: [Microsoft][ODBC Driver 17 for SQL Server][SQL
Server]Incorrect syntax near the keyword (SQL: select
YEAR(Datum) as the_year, MONTH(Datum) as the_month, SUM(Menge) as
stunden from [BELEGP]
So I think there is just one small thing wrong but can't figure out what.
Any ideas?
Solution
Just found the the solution:
$positions = selectlineBelegPos::select(
DB::raw("YEAR(Datum) AS year"),
DB::raw("MONTH(Datum) AS month"),
DB::raw("SUM(Menge) AS stunden")
)
->groupBy(DB::raw("YEAR([Datum])"),DB::raw("MONTH([Datum])"))
->get();
Indeed isn't the dynamically value names (year and month) unavailable in the GROUPBY clause, instead you have to call the DB::raw again but now without generating the key words again.
thank you all for the support!
In SSIS, I am trying to pull in table data from a large Data warehouse for some analysis in Excel. I have written the following query:
SELECT journal_name AS Journal_Name,
division AS DIV,
account AS Acct,
cost_center AS CC,
effective_date AS Effective_Date,
effective_month AS Month,
effective_year AS Year,
posted_date AS Posted_Date,
source AS Source,
line_description AS Line_Description,
category AS Category,
entered_amount AS E_Entered_Amount,
entered_currency AS E_Currency,
functional_amount AS Fuctional_Amount,
functional_currency AS F_Currency
FROM corp.source
WHERE ( (division = 'C301' )
AND ( account LIKE '%' )
AND ( cost_center = '8D' )
AND ( effective_month BETWEEN '01' AND '10' )
AND ( effective_year = '2019' ) )
ORDER BY posted_date
I am doing this with ODBC Source as I have taken Oracle connector info from a Microsoft Access tool. I run the parse in the ODBC screen and I look at the preview and get no issues. However, when I try to run this package just to make sure the connection works, I get:

Package Validation Error (Package Validation Error)

I'm not quite sure what column is causing the error. I have dealt with this exact same data in the past and was able to change all of the data coming in the Advanced Editor into Wide Strings [WSTR] when using OLE DB, then used data conversion to fix it and it worked very well. However, every time I try and change the type of the external data in this ODBC source advanced editor, it keeps resetting to the original data types. Is there a better way to do this, or is there a reason I cannot reset that incoming data to WSTR to deal with it?
Thanks.
I'm trying to make a simple select on my table mapped with sqlalchemy but I can't get it to match the exact table name.
As I noticed, the output of this:
class Users(base):
__tablename__ = "users"
[...]
was
[Microsoft][SQL Server Native Client 11.0][SQL Server]Invalid object name 'users'
And I tried to fix the error by explicitly writing the database I'm refering to
class Users(base):
__tablename__ = "[homework-3-cc-database].users"
[...]
giving the output:
[Microsoft][SQL Server Native Client 11.0][SQL Server]Incorrect syntax near ']'.
I noticed that it inserted some square brackets, unwanted. Here is their SQL statement:
[SQL: SELECT TOP 1 [[homework-3-cc-database].users].user_id AS [[homework-3-cc-database].users_user_id]
FROM [[homework-3-cc-database].users]]
This statement, ran from DataGrip works just fine:
SELECT TOP 1 [homework-3-cc-schema].users.user_id
FROM [homework-3-cc-schema].users
Do you have any suggestions regarding how should I fix this?
I had to specify the schema name in the following way:
__table_args__ = {"schema": "homework-3-cc-schema"}
I'm trying to run a custom query on my DB with Doctrine2 using the following:
$qb = $em->createQueryBuilder();
$qb->select(array('c', 'count(uc) as numMembers'))
->from('AcmeGroupBundle:Group', 'c')
->leftJoin('c.members', 'uc', 'WITH', 'uc.community = c.id')
->groupBy('c')
->orderBy('numMembers', 'DESC')
->setFirstResult( $offset )
->setMaxResults( $limit );
$entities = $qb->getQuery()->getResult();
This query runs flawlessly on my local MySQL DB. But when I try to run it against my production DB (MSSQL), i get the following error:
SQLSTATE[42000]: [Microsoft][SQL Server Native Client 11.0][SQL Server]Column 'Group.discr' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
I do have a discriminator column because I have classes inheriting from Group.
Any suggestions on how should I change the query to make it compatible with MSSQL?
Thanks!
