plugins are added inside build.gradle(app) and classpaths are added inside build.gradle(project).

QUESTION
I was trying to write a query in java stream, through speedment.
When I try to sum (l_extendedprice * (1 - l_discount))
in select, I get this error:
Bad return type in lambda expression: BigDecimal cannot be converted to long. Operator '-' cannot be applied to 'int', 'java.math.BigDecimal'.
My code is this:
...ANSWER
Answered 2019-May-30 at 20:57So the problem is that +
, -
, *
, /
, ... are not working with BigDecimal
s. You have to use .add()
, .subtract()
, .multiply()
, .divide()
, ... methods for calculations.
If it is possible, you can use BigDecimal.longValue()
or BigDecimal.longValueExact()
to convert the BigDecimal
s to long values to use them in your calculation:

I have implemented the persistence layer using Speedment and I would like to test the code using spring boot unit tests. I have annotated my unit tests with the following annotations:
...ANSWER
Answered 2017-Oct-31 at 17:19AFAIK it does not (yet) - correction: it seems to setup one transaction per stream / statement.
See this article: https://dzone.com/articles/best-java-orm-frameworks-for-postgresql
But it should be possible to implement with writing a custom extension: https://github.com/speedment/speedment/wiki/Tutorial:-Writing-your-own-extensions
Edit:
According to a speedment developer one stream maps to one transaction: https://www.slideshare.net/Hazelcast/webinar-20150305-speedment-2
QUESTION
I have a Speedment project set up but I do not want to run the GUI Tool and I do not want to check in the generated files in my software repository (GIT). How can I make Speedment automatically regenerate all code on build?

QUESTION
When Speedment generates entities from a database schema, is there some way to change the default type being generated? For an example, if I have a table like this:
...ANSWER
Answered 2017-May-05 at 23:25In the Tool, select the "posted_date"-column on the left side and change the "Type Mapper" property to "Timestamp to Long". When you regenerate the code, then that column will be represented as a long instead.
If you want to create a custom type mapper, there is a good tutorial for that on the Speedment GitHub page.

I have a database table that I want to filter and then sort in reversed (descending) order. How do I express that in a Speedment stream similar to this:

How can I use OR when I want to filter Speedment streams? How do I write a stream with users that are either from NY, NJ or PA?

QUESTION
Is there any way to explicitly set which directory/package where Speedment will put generated code? By default it creates a path like "com.company.project.db0.myschema.mytable" but maybe I want something like "com.company.database".
...ANSWER
Answered 2017-May-04 at 16:59The directory where source code is generated and the root package for a particular project are two different settings. Both can be configured either in the graphical tool or in the speedment.json-file.
Using the Tool
In the tool, select the root item in the "Node hierarchy" and deselect the "Auto" box to the right of "Package location" and "Package name". You can then enter the desired directory and package name here. You can also select a specific package name for each table by editing that node in the "Node hierarchy".
Without Using the Tool
If you don't want to use the tool, you can do the same changes directly in the speedment.json file. Locate the project and add/edit the following attributes:
