My query in HQL is basically:
select functionA(a, :paramA), functionB(b, :paramB), functionC(c, :paramC), sum(d)
from tableA
groupby by functionA(a, :paramA), functionB(b, :paramB), functionC(c, :paramC)
However this gets turned into SQL of
select functionA(a, #param0), functionB(b, #param1), functionC(c, #param2), sum(d)
from tableA
groupby by functionA(a, #param3), functionB(b, #param4), functionC(c, #param5)
Now obviously this is going to throw a 'blah' is invalid in the select list because.... error as the group by clause doesn't match the select clause. I'm about to change this to a string format so I can get on with some productive work but if anyone has the answer as to why NHibernate will not reuse the same named query input the 2 times it is used that would be much appreciated.
A similar question seems to have been asked here with no real answer either.
This has been solved in NHibernate 3.0.0.Alpha1. You can get it here

I am quite new to access database and can't wrap my head around why a syntax error keeps popping up every time I try to run this query, I hope that you're able to help
SELECT Customer.forename, Customer.surname
FROM Customer, Booking
WHERE Booking.customerID=Customer.CustomerID AND Booking.childTicket=(SELECT
MAX(Booking.childTicket))
GROUP BY Customer.forename, Customer.surname;
The error says: Syntax error in query expression Booking.customerID=Customer.CustomerID AND Booking.childTicket=(SELECT MAX(Booking.childTicket)).
You must provide a complete subquery:
WHERE Booking.customerID=Customer.CustomerID AND Booking.childTicket=
(SELECT MAX(Booking.childTicket) FROM Booking)
I am pretty new to the DAX world. I am trying to do get distinct records on multiple columns in DAX query similar to the way I do in SQL. I tried joining two tables based on the model in the Query Designer which gave me the following query.
EVALUATE SUMMARIZECOLUMNS(
'Dim_Products'[SaleCode],
'Dim_Products'[ProducttName],
'Dim_TimeZone'[StartDate],
'Dim_TimeZone'[StartTime],
'Dim_TimeZone'[EndDate],
'Dim_TimeZone'[EndTime],
'Dim_TimeZone'[Variation],
"Fact_Sales_Count", [Fact_Sales_Count]
)
Running the above is giving duplicate records. How do I just get distinct records as I am trying to call this from SSRS?
Thanks!
Look at: https://www.sqlbi.com/articles/introducing-summarizecolumns/
You switch from "group by" columns to "summary" columns by convention in the argument list to SUMMARIZECOLUMNS.
EG:
EVALUATE SUMMARIZECOLUMNS(
'Dim_Products'[SaleCode],
'Dim_Products'[ProducttName],
'Dim_TimeZone'[StartDate],
'Dim_TimeZone'[StartTime],
'Dim_TimeZone'[EndDate],
'Dim_TimeZone'[EndTime],
'Dim_TimeZone'[Variation],
"Fact_Sales_Count", sum([Fact_Sales_Count])
)
Just in case if this helps someone in future.
EVALUATE
DISTINCT(
SELECTCOLUMNS('Dim_Products',
'Dim_Products'[SaleCode],
'Dim_Products'[ProducttName],
'Dim_TimeZone'[StartDate],
'Dim_TimeZone'[StartTime],
'Dim_TimeZone'[EndDate],
'Dim_TimeZone'[EndTime],
'Dim_TimeZone'[Variation]))
And, if we need to add a filter:
EVALUATE
DISTINCT(
SELECTCOLUMNS(
FILTER('Dim_Products', 'Dim_Products'[SaleCode] = 123 && ('Dim_Products'[ProducttName] = "ABC" || 'Dim_Products'[ProducttName] = "XYZ" )),
'Dim_Products'[SaleCode],
'Dim_Products'[ProducttName],
'Dim_TimeZone'[StartDate],
'Dim_TimeZone'[StartTime],
'Dim_TimeZone'[EndDate],
'Dim_TimeZone'[EndTime],
'Dim_TimeZone'[Variation]))
So, I have Hibernate 5.3.1 in a project which connects to different enginees (MySql, Oracle, PostgreSQL and MS SQL), so I can't use native queries.
Let's say I have 3 records in a table, which all of them have the same datetime, but I need to group them only by date (not time). For example, 2019-12-04;
I execute this query:
SELECT
CONCAT(year(tx.date_), month(tx.date_), day(tx.date_)),
iss.code,
COUNT(tx.id)
FROM
tx_ tx
JOIN
issuer_ iss
ON
tx.id_issuer = iss.id
GROUP BY
CONCAT(year(tx.date_), month(tx.date_), day(tx.date_)), iss.code
But, when I test it connected to SQL SERVER 2017, instead of return 20191204, it's returning 2035. In Oracle and MySQL is working fine.
Anyone has any idea why is this happen? I've tried different ways, like use + instead of CONCAT but the result is the same.
I've also tried to extract them for separate (without concat), and they have been returning correct. The problem is, I need to group them by the complete date.
And just for the record, the field is declared as datetime2 in DDBB
How about simply adding them, instead of using CONCAT.
(year(tx.date_)*10000 + month(tx.date_)*100 + day(tx.date_)*1) AS datenum
Thus, try this:
SELECT
CAST((year(tx.date_)*10000 + month(tx.date_)*100 + day(tx.date_)*1) AS string) AS datenum,
iss.code
FROM tx_ tx
JOIN issuer_ iss
ON tx.id_issuer = iss.id
GROUP BY year(tx.date_), month(tx.date_), day(tx.date_), iss.code
Thanks for the hint Gert Arnold gave me. I just didn't realize that the query was adding like if they were numbers in MSSQL.
Finally, I manage to make it work in the 4 RDBMS casting to string first
SELECT
CONCAT(CAST(year(tx.date_) AS string), CAST(month(tx.date_) AS string), CAST(day(tx.date_) AS string)),
iss.code
FROM
tx_ tx
JOIN
issuer_ iss
ON
tx.id_issuer = iss.id
GROUP BY
CONCAT(year(tx.date_), month(tx.date_), day(tx.date_)), iss.code
I tried also casting to TEXT, but it throws exception in MySQL
Why use concat() to begin with?
Assuming Hibernate takes care of converting the non-standard year(), month() and day() functions, then the following should work on any DBMS
SELECT year(tx.date_), month(tx.date_), day(tx.date_), iss.code
FROM tx_ tx
JOIN issuer_ iss ON tx.id_issuer = iss.id
GROUP BY year(tx.date_), month(tx.date_), day(tx.date_), iss.code
I am struggling with querying a value from an XML. I am new in this world so please forgive me if the answer is actually obvious and i am just not seeing it :)
<documentid>
<id accountingentity="200" lid="...."
variationid="6370">aa0000012</id>
</documentid>
I want to query the value "aa0000012" but I am not able to do it since there is no Xpath for this value available.
I tried it with this query right here but it is only giving me the whole content:
select
#salesorderxml.query('/syncsalesorder/dataarea/salesorder/salesorderheader/documentid/id')
Can anyone please help me? Thanks
This should work whether you have multiple documentid's or not
select o.value('id[1]', 'varchar(max)')
from #salesorderxml.nodes('/documentid') as t(o)
it basically says give me the nodes named documentid, then give me the value of element id
Try this - it will reach into the XML and fetch the element value of <id>:
SELECT
XC.value('text()[1]', 'varchar(100)')
FROM
#salesorderxml.nodes('/documentid/id') AS XT(XC)
This returns:
(No column name)

aa0000012
I have an xml column called OrderXML in an Orders table...
there is an XML XPath like this in the table...
/Order/InternalInformation/InternalOrderBreakout/InternalOrderHeader/InternalOrderDetails/InternalOrderDetail
There InternalOrderDetails contains many InternalOrderDetail nodes like this...
<InternalOrderDetails>
<InternalOrderDetail>
<Item_Number>FBL11REFBK</Item_Number>
<CountOfNumber>10</CountOfNumber>
<PriceLevel>FREE</PriceLevel>
</InternalOrderDetail>
<InternalOrderDetail>
<Item_Number>FCL13COTRGUID</Item_Number>
<CountOfNumber>2</CountOfNumber>
<PriceLevel>NONFREE</PriceLevel>
</InternalOrderDetail>
</InternalOrderDetails>
My end goal is to modify the XML in the OrderXML column IF the Item_Number of the node contains COTRGUID (like '%COTRGUID') AND the PriceLevel=NONFREE. If that condition is met I want to change the PriceLevel column to equal FREE.
I am having trouble with both creating the xpath expression that finds the correct nodes (using OrderXML.value or OrderXML.exist functions) and updating the XML using the OrderXML.modify function).
I have tried the following for the where clause:
WHERE OrderXML.value('(/Order/InternalInformation/InternalOrderBreakout/InternalOrderHeader/InternalOrderDetails/InternalOrderDetail/Item_Number/node())[1]','nvarchar(64)') like '%13COTRGUID'
That does work, but it seems to me that I need to ALSO include my second condition (PriceLevel=NONFREE) in the same where clause and I cannot figure out how to do it. Perhaps I can put in an AND for the second condition like this...
AND OrderXML.value('(/Order/InternalInformation/InternalOrderBreakout/InternalOrderHeader/InternalOrderDetails/InternalOrderDetail/PriceLevel/node())[1]','nvarchar(64)') = 'NONFREE'
but I am afraid it will end up operating like an OR since it is an XML query.
Once I get the WHERE clause right I will update the column using a SET like this:
UPDATE Orders SET orderXml.modify('replace value of (/Order/InternalInformation/InternalOrderBreakout/InternalOrderHeader/InternalOrderDetails/InternalOrderDetail/PriceLevel[1]/text())[1] with "NONFREE"')
However, I ran this statement on some test data and none of the XML columns where updated (even though it said zz rows effected).
I have been at this for several hours to no avail. Help is appreciated. Thanks.
if you don't have more than one node with your condition in each row of Orders table, you can use this:
update orders set
data.modify('
replace value of
(
/Order/InternalInformation/InternalOrderBreakout/
InternalOrderHeader/InternalOrderDetails/
InternalOrderDetail[
Item_Number[contains(., "COTRGUID")] and
PriceLevel="NONFREE"
]/PriceLevel/text()
)[1]
with "FREE"
');

If you could have more than one node in one row, there're a several possible solutions, none of each is really elegant, sadly.
You can reconstruct all xmls in table - sql fiddle demo
or you can do your updates in the loop - sql fiddle demo
This may get you off the hump.
Replace #HolderTable with the name of your table.
SELECT T2.myAlias.query('./../PriceLevel[1]').value('.' , 'varchar(64)') as MyXmlFragmentValue
FROM #HolderTable
CROSS APPLY OrderXML.nodes('/InternalOrderDetails/InternalOrderDetail/Item_Number') as T2(myAlias)
SELECT T2.myAlias.query('.') as MyXmlFragment
FROM #HolderTable
CROSS APPLY OrderXML.nodes('/InternalOrderDetails/InternalOrderDetail/Item_Number') as T2(myAlias)
EDIT:
UPDATE
#HolderTable
SET
OrderXML.modify('replace value of (/InternalOrderDetails/InternalOrderDetail/PriceLevel/text())[1] with "MyNewValue"')
WHERE
OrderXML.value('(/InternalOrderDetails/InternalOrderDetail/PriceLevel)[1]', 'varchar(64)') = 'FREE'
print ##ROWCOUNT
Your issue is the [1] in the above.
Why did I put it there?
Here is a sentence from the URL listed below.
Note that the target being updated must be, at most, one node that is explicitly specified in the path expression by adding a "[1]" at the end of the expression.
http://msdn.microsoft.com/en-us/library/ms190675.aspx
EDIT.
I think I've discovered the the root of your frustration. (No fix, just the problem).
Note below, the second query works.
So I think the [1] is some cases is saying "only ~~search~~ the first node".....and not (as you and I were hoping)...... "use the first node..after you find a match".
UPDATE
#HolderTable
SET
OrderXML.modify('replace value of (/InternalOrderDetails/InternalOrderDetail/PriceLevel/text())[1] with "MyNewValue001"')
WHERE
OrderXML.value('(/InternalOrderDetails/InternalOrderDetail/PriceLevel[text() = "NONFREE"])[1]', 'varchar(64)') = 'NONFREE'
/* and OrderXML.value('(/InternalOrderDetails/InternalOrderDetail/Item_Number)[1]', 'varchar(64)') like '%COTRGUID' */
UPDATE
#HolderTable
SET
OrderXML.modify('replace value of (/InternalOrderDetails/InternalOrderDetail/PriceLevel/text())[1] with "MyNewValue002"')
WHERE
OrderXML.value('(/InternalOrderDetails/InternalOrderDetail/PriceLevel[text() = "FREE"])[1]', 'varchar(64)') = 'FREE'
Try this :
;with InternalOrderDetail as (SELECT id,
Tbl.Col.value('Item_Number[1]', 'varchar(40)') Item_Number,
Tbl.Col.value('CountOfNumber[1]', 'int') CountOfNumber,
case
when Tbl.Col.value('Item_Number[1]', 'varchar(40)') like '%COTRGUID'
and Tbl.Col.value('PriceLevel[1]', 'varchar(40)')='NONFREE'
then 'FREE'
else
Tbl.Col.value('PriceLevel[1]', 'varchar(40)')
end
PriceLevel
FROM (select id ,orderxml from demo)
as a cross apply orderxml.nodes('//InternalOrderDetail')
as
tbl(col) ) ,
cte_data as(SELECT
ID,
'<InternalOrderDetails>'+(SELECT ITEM_NUMBER,COUNTOFNUMBER,PRICELEVEL
FROM InternalOrderDetail
where ID=Results.ID
FOR XML AUTO, ELEMENTS)+'</InternalOrderDetails>' as XML_data
FROM InternalOrderDetail Results
GROUP BY ID)
update demo set orderxml=cast(xml_data as xml)
from demo
inner join cte_data on demo.id=cte_data.id
where cast(orderxml as varchar(2000))!=xml_data;
select * from demo;
SQL Fiddle
I have handled following cases :
1. As required both where clause in question.
2. It will update all <Item_Number> like '%COTRGUID' and <PriceLevel>= NONFREE in one
node, not just the first one.
It may require minor changes for your data and tables.
