We have a large number of price lists which are often dumped for review, my problem is not getting the data but labeling the output columns with the price list name so they make sense to the end user. Almost every time I run the query the combination of price lists change. The actual output is much wider than the simplified sample below making it rather laborious to go through and change all the individual column names. Is there a way to use the variable to label the columns as in the sample ?
(I am self taught in sql and consider myself to be at a basic level.)
Thanks for your time.

I have 2 entites, PERSON and PEOPLE
PERSON has columns namely -> FN, LN
PEOPLE has columns -> FIRST, LAST
I want to fetch the union of both the tables together. How do I do it in JPA.
I have used the below way:
Created a new DTO -> Human having 2 fields FIRSTNAME and LASTNAME (case sensitive)
#Query(value=" SELECT FIRSTNAME, LASTNAME FROM "+
"( SELECT "+
" P.FN AS FIRSTNAME, "+
" P.LN AS LASTNAME " +
" FROM PERSON P"+
" UNION "+
" SELECT "+
" A.FIRST AS FIRSTNAME, "+
" A.LAST AS LASTNAME ' +
" FROM PEOPLE A"+
")", nativeQuery = true)
Pageable<Human> getEntireHumanRace() {
....
}
The SQL runs fine, but the ORM always forms a malformed SQL
such as "Syntax error in SQL statement SELECT COUNT(P) FROM PERSON P ...."
InvalidDataAccessResourceUsageException: could not prepare statement
Is there any suggestion on what can be done? Why does it put the count in front of the generated query?
Appreciate in advance.
Why does it put the count in front of the generated query?
Because you are trying to get data with pagination (Pageable). So for total element count Count query executing.
Is there any suggestion on what can be done?
You are using class-based projection and use List<Human>
#Query(value="SELECT FIRSTNAME, LASTNAME FROM ...")
List<Human> getEntireHumanRace();
I'm using spring data with a postgresql server and i want to perform some GPS-data range queries. This means, given a coordinate i compute on the fly the distance from the entry to the given point and check for a certain range.
Since i also want to order my data regarding the distance and additionally i want to retrieve the actual distance too, in sql i would use the AS keyword to compute the expression only once and then use this auxiliary expression in the where and the order by part.
However, so far I haven't yet figured out how to do this in jqpl. So my query should do something like this:
SELECT NEW Result(p, <distance-expression>) FROM MyModel p where <distance-expression> <= :rangeParam order by <distance-expression>
however, i'm afraid that the will be evaluated more than once for each entry and so this will have a negative impact on the runtime/response time of the query.
Is there any way in jqpl to use the AS keyword to avoid the multiple evaluation of
<distance-expression>?
Best regards
A native query with an inner view should get the job done. Assuming class Location(id, latitude, longitude) and the Haversine formula for finding distances between points on great circles, the following repository method declaration with a custom native query should be sufficient:
#Query(nativeQuery = true
, value = "SELECT "
+ " r.id "
+ " , r.latitude "
+ " , r.longitude "
+ "FROM "
+ " (SELECT "
+ " l.id AS id "
+ " , l.latitude AS latitude "
+ " , l.longitude AS longitude "
+ " , 2 * 6371 * ASIN(SQRT(POWER(SIN(RADIANS((l.latitude - ?1) / 2)), 2) + COS(RADIANS(l.latitude))*COS(RADIANS(?1))*POWER(SIN(RADIANS((l.longitude - ?2) / 2)), 2))) AS distance "
+ " FROM "
+ " location l) AS r "
+ "WHERE "
+ " r.distance < ?3")
List<Location> findAllByProximity(BigDecimal latitude
, BigDecimal longitude
, BigDecimal distance);
Sample available on Github as an example (metric units assumed).
Note: The reason behind using a native query in the example as opposed to JPQL is the lack of support for trigonometric functions in JPQL. In cases where the expression is simpler and can be coded using native JPQL functions, the native query can be replaced with a JPA query.
I'm getting an exception error saying missing operators can anyone help
string sql = "Select SalesPerson.Name, Item.Description, Orders.Quantity, Orders.OrderDate"
+ "From([Orders]"
+ "Inner Join[SalesPerson] On Orders.SalesPersonID=SalesPerson.SalesPersonID)"
+ "Inner Join[Item] On Orders.ItemNumber=Item.ItemNumber"
+ "Where Orders.CustomerID=#customer Order by Orders.OrderDate DESC";
You need to add some spaces at the end of each of your lines of SQL!
string sql = "SELECT SalesPerson.Name, Item.Description, Orders.Quantity, Orders.OrderDate "
+ "FROM [Orders] "
+ "INNER JOIN [SalesPerson] ON Orders.SalesPersonID = SalesPerson.SalesPersonID "
+ "INNER JOIN [Item] ON Orders.ItemNumber = Item.ItemNumber "
+ "WHERE Orders.CustomerID = #customer "
+ "ORDER BY Orders.OrderDate DESC";
Otherwise, your SQL ends up being
Select ..... Orders.OrderDateFROM([Orders]Inner Join[SalesPerson] .....
and so on - and that's just not valid SQL.
I also removed some unnecessary parenthesis around the JOIN operators - those are only needed for MS Access, but since you're saying you're using ADO.NET, I assume this is not for MS Access and therefore, those parenthesis are not needed
I am trying to update a date field in a table to the current date when a button is clicked on a form and that given field is empty. However, when the field is updated, the output is the time 12:00:05, not a date at all. When year(date) is used instead, 7/7/1905 is the output. I am not sure why these values are my outputs. Here is my code:
Dim ctl As Control
Set ctl = [Forms]![frm1]![subfrm1].[Form]![CloseDate]
If IsNull(ctl) Then
DoCmd.SetWarnings False
DoCmd.RunSQL "Update tbl1 SET [CloseItem] = ""YES"" WHERE [ID] = " & [Forms]![frm1]![ID].Value & " AND [Item#] = " & [Forms]![frm1]![subfrm1].[Form]![ItemID].Value
DoCmd.RunSQL "Update tbl1 SET [CloseDate] = " & Date & " WHERE [ID] = " & [Forms]![frm1]![ID].Value & " AND [ItemID] = " & [Forms]![frm1]![subfrm1].[Form]![ItemID].Value
' Output is 12:00:05
' OR DoCmd.RunSQL "Update tbl1 SET [CloseDate] = " & Year(Date) & " WHERE [ID] = " & [Forms]![frm1]![ID].Value & " AND [ItemID] = " & [Forms]![frm1]![subfrm1].[Form]![ItemID].Value
DoCmd.RefreshRecord
' Output is 7/7/1905
End If
How can I get it to output the correct date?
Examine the string your code builds for this segment of the UPDATE statement. (This is an example copied from the Access Immediate window. You can go there with Ctrl+g)
? "Update tbl1 SET [CloseDate] = " & Date & " WHERE [ID] = "
Update tbl1 SET [CloseDate] = 2/16/2015 WHERE [ID] =
The db engine does not see 2/16/2015 as a Date/Time value. Instead, it treats that as 2 divided by 16 divided by 2015. And the resulting number, when expressed as a Date/Time value, gives you this ...
? Format(2/16/2015, "yyyy-m-d hh:nn:ss")
1899-12-30 00:00:05
You can signal the db engine that 2/16/2015 is a Date/Time value by enclosing it in # delimiters like this: #2/16/2015#
However, since the db engine understands the Date() function, you can use that function name directly in your UPDATE statement and not bother about concatenating in a value with proper delimiters.
Dim strUpdate As String
strUpdate = "Update tbl1 SET [CloseDate] = Date() WHERE [ID] = " & _
[Forms]![frm1]![ID].Value & " AND [ItemID] = " & _
[Forms]![frm1]![subfrm1].[Form]![ItemID].Value
Debug.Print strUpdate
CurrentDb.Execute strUpdate, dbFailOnError
Tutorials and samples about JPQL always deal with SELECT statement and sometimes, simple UPDATE statements. I need to update a table with a join.
I have simplified my env :
KEY
= id
- counter
APPLET
= id
! key_id (1-1)
DEVICE
= id
! applet_id (1-1)
! user_id (1-n)
USER
= id
- login
A device has a unique applet, which has a unique keyset. But an user can own several devices.
I need to reset the counter of every KEY attached to the USER login "x".
I tried some syntax with UPDATE and JOIN, without success. Any clue ?
Thank you.
What did you try and what error did you get? What is your object model?
Perhaps something like,
Update Key k set k.counter = 0 where exists (Select u from User u join u.devices d where u.login = "x" and d.applet.key = k)
See,
http://en.wikibooks.org/wiki/Java_Persistence/JPQL_BNF#Update
You could also select the objects and reset the counter in memory and commit the changes.
JPQL does not support join operations in bulk update operations.
When you edit query, nativeQuery = true, you can join.
Query should be written according to the fields in the database.
#Transactional
#Modifying
#Query(nativeQuery = true,
value = "UPDATE Team t" +
" SET current = :current " +
" FROM " +
" members," +
" account" +
" WHERE " +
" members.members_id = t.members_id " +
" AND members.account_id = :account " +
" AND t.current = :current_true ")
int updateTeam(
#Param("current") String current,
#Param("account") Long account,
#Param("current_true") Integer current_true);
